Impacts of caring for a child with the CDKL5 disorder on parental wellbeing and family quality of life

Validating the Communication and Symbolic Behavior Scales-Developmental Profile Infant-Toddler Checklist (CSBS-DP ITC) Beyond Infancy in the CDKL5 Deficiency Disorder

CDKL5 deficiency disorder (CDD) results in early-onset epilepsy and lifelong cognitive and motor impairments. With no validated measure for communication in CDD, this study evaluated the psychometric properties of the Communication and Symbolic Behavior Scales-Developmental Profile Infant Toddler Checklist (CSBS-DP ITC). Caregivers (n = 150; affected individuals aged 1-29 years) completed the CSBS-DP ITC. Distribution of scores indicated a floor effect. There was poor divergent validity for the three-factor model but goodness of fit and convergent validity data were satisfactory for the one-factor model. Individuals with poorer overall functional abilities scored lower on the CSBS-DP ITC. Test-retest reliability was excellent. The floor effect could explain the very high reliability, suggesting problems as a sensitive outcome measure in clinical trials for CDD.

Growth patterns in individuals with CDKL5 deficiency disorder

AIM

To compare growth in individuals with cyclin-dependent kinase-like 5 (CDKL5) deficiency disorder with population norms and to investigate the effect of gastrostomy on growth.

METHOD

The longitudinal study included 353 individuals from the International CDKL5 Disorder Database with any anthropometric measurement in baseline and/or follow-up questionnaires. The British 1990 growth reference was used to determine the age- and sex-standardized z-score. Repeated cross-sectional data were fitted using a Gaussian linear regression model with generalized estimating equations.

RESULTS

All growth parameters were below the general population norm (mean z-scores: weight -0.97, height -0.65, body mass index [BMI] -0.81, head circumference -2.12). The disparity was particularly pronounced for all anthropometric measurements after 4 years of age except for BMI. Moreover, individuals with gastrostomy placement were shown to have a larger decrease than those without.

INTERPRETATION

In addition to weight, height, and BMI, head circumference was also compromised in this disorder. Microcephaly could be considered a helpful diagnostic feature, especially in adults. Any benefit of gastrostomy on weight and BMI was mainly seen in the early years.

Psychological aspects of being a parent of an individual with Rett syndrome: A scoping review

BACKGROUND

Rett syndrome (RTT) causes multiple disabilities with a lifelong need for substantial care, placing a tremendous lifelong responsibility on the parents. Parenting an individual with RTT can therefore be challenging. Research on the psychological aspects of parenting individuals with RTT is limited and unclear. We aimed to identify and map the existing literature on this subject.

METHOD

A scoping review was conducted with systematic searches in PubMed, PsycINFO and CINAHL.

RESULTS

Eighteen studies were included. Negative and positive psychological aspects were described with the majority focusing on the negative. Three factors seemed to especially affect the parents: severity of the diagnosis, time (increasing age of parents or individual with RTT; years of caretaking), work-status of the mother.

CONCLUSIONS

Seemingly, parents are highly affected; however, the literature is scarce and has several gaps. Future research should include older parents, fathers, parents of individuals living in group homes, and positive aspects.

Quality of life in caregivers of a child with a developmental and epileptic encephalopathy

AIM

To explore the relationship between social care-related quality of life (SCrQoL) for caregivers of a child with a developmental and epileptic encephalopathy (DEE; such as SCN2A and Dravet syndrome) and health literacy, illness perceptions, and caregiver activation.

METHOD

As part of a larger pre-post pilot study of an information linker service, caregivers completed a baseline questionnaire which included demographics and measures to assess SCrQoL, health literacy, illness perceptions, and caregiver activation. We used Spearman's Rho to determine relationships between variables.

RESULTS

Seventy-two caregivers completed the questionnaire. Total SCrQoL varied widely, ranging from an 'ideal state' to 'high needs state'. Caregivers most frequently reported high needs regarding doing activities they enjoy and looking after themselves. Total SCrQoL was correlated with cognitive (r[70] = -0.414, p < 0.000) and emotional representations of illness (r[70] = -0.503, p < 0.000), but not coherence (r = -0.075, p = 0.529). Total SCrQoL was not correlated with health literacy (r[70] = 0.125, p = 0.295) or caregiver activation (r[70] = 0.181, p = 0.127).

INTERPRETATION

Future research should explore whether interventions that help caregivers cognitively reframe the negative experiences of having a child with a DEE, and support them to partake in activities they enjoy, boost their SCrQoL.

WHAT THIS PAPER ADDS

Caregiver social care-related quality of life (SCrQoL) varied widely, from 'ideal state' to 'high needs state'. Most common high needs were doing enjoyable activities and self-care. Caregivers with higher SCrQoL may perceive their child's illness as less threatening. SCrQoL does not appear to be related to caregiver activation in this sample.

Stakeholder Perceptions of Complementary and Integrative Medicines from People Living with Rare Diseases in Northern Ireland: A Mixed Methods Study

INTRODUCTION

Only 5% of rare diseases have an approved treatment available, therefore patients often utilise complementary and integrative medicines (CIMs) to help manage their condition. Limited high-quality evidence-based studies are available which support the effectiveness of CIM, as it is difficult to show that an outcome is a direct result of the CIM intervention and not due to bias. Patients and healthcare professionals must weigh up the evidence quality, safety, efficacy, practical logistics, and financial implications of utilising CIM for rare diseases. This study aimed to elucidate perspectives of stakeholders (individuals with rare diseases, carers, family members, CIM practitioners and healthcare professionals), on the usage of CIM for rare diseases across Northern Ireland.

METHODS

This was a mixed methods study. An online survey was open from January to February 2019 (n = 29 responses). Themes identified from the survey were then discussed with stakeholders in a semi-structured discussion workshop in March 2019.

RESULTS

A limited number of participants responded to the survey (n = 29). Some individuals with rare diseases reported CIM as effective in the management of their condition, in particular acupuncture, dietary supplements, herbal medicines, homoeopathy, hydrotherapy, kinesiology, mindfulness, pilates, reflexology, tai chi, and yoga. However, a number of respondents (n = 7) experienced a negative side effect from CIM. Workshop participants raised concerns over the lack of information available about CIM and rare disease. Both the survey and workshop identified inequality of access with participants reporting CIM to be expensive.

CONCLUSIONS

More information, high-quality research, and education about CIM are required for patients and healthcare professionals to help make informed decisions about the usage of CIM for rare diseases. Improved communication, information, and health and social care in general would help individuals be more confident and knowledgeable about therapeutic options in relation to their rare disease(s).

Einleitung

Nur für fünf Prozent der seltenen Erkrankungen existiert eine zugelassene Behandlung, weshalb Patienten häufig komplementäre und integrative Medizin (CIM) nutzen, um ihre Krankheit zu behandeln. Es liegen nur wenige qualitativ hochwertige evidenzbasierte Studien vor, die die Wirksamkeit von CIM stützen, da sich schwer nachweisen lässt, dass ein Behandlungsergebnis direkt durch die CIM-Intervention bedingt und nicht Folge einer Verzerrung ist. Patienten und Angehörige der Gesundheitsberufe müssen die Qualität der Evidenz, die Sicherheit und Wirksamkeit sowie praktische logistische Aspekte und die finanziellen Folgen der Anwendung von CIM bei seltenen Erkrankungen abwägen. Mit der vorliegenden Studie sollte die Perspektive der Betroffenen (Menschen mit seltenen Erkrankungen, Betreuungspersonen, Familienangehörige, CIM-Praktiker und Angehörige der Gesundheitsberufe) in Bezug auf die Anwendung von CIM bei seltenen Erkrankungen in Nordirland untersucht werden.

Methoden

Es handelte sich um eine Studie mit gemischten Methoden. Eine Online-Umfrage war von Januar bis Februar 2019 geöffnet (n = 29 Antworten). Die in der Umfrage ermittelten Themen wurden anschließend im März 2019 im Rahmen eines halbstrukturierten Diskussionsworkshops mit den Betroffenen erörtert.

Ergebnisse

Eine begrenzte Anzahl von Teilnehmern antwortete auf die Umfrage (n = 29). Einige Personen mit seltenen Erkrankungen gaben an, dass CIM bei der Behandlung ihrer Erkrankung wirksam war, insbesondere Akupunktur, Nahrungsergänzungsmittel, pflanzliche Arzneimittel, Homöopathie, Hydrotherapie, Kinesiologie, Achtsamkeit, Pilates, Reflexologie, Tai Chi und Yoga. Einige Befragte (n = 7) berichteten jedoch über negative Nebenwirkungen der CIM. Die Workshop-Teilnehmer äußerten Bedenken in Bezug auf den Mangel an Informationen über CIM und seltene Erkrankungen. Sowohl in der Umfrage als auch im Workshop zeigte sich eine Ungleichheit beim Zugang zu CIM und die Teilnehmer berichteten, dass CIM teuer sei.

Schlussfolgerungen

Patienten und Angehörige der Gesundheitsberufe benötigen mehr Informationen, qualitativ hochwertige Forschung und Aufklärung über CIM, um fundierte Entscheidungen über die Anwendung von CIM bei seltenen Erkrankungen treffen zu können. Eine bessere Kommunikation, Information sowie gesundheitliche und soziale Versorgung im Allgemeinen würden zu mehr Selbstvertrauen und Wissen der Betroffenen über die therapeutischen Möglichkeiten im Zusammenhang mit ihrer seltenen Erkrankung beitragen.

Quality of life of Brazilian families who have children with Fragile X syndrome: a descriptive study

This study aimed to assess the Family Quality of Life (FQoL) of Brazilian families with male children with Fragile X syndrome (FXS). Data from 53 families were collected using forms that included sociodemographic and clinical information, as well as the Beach Center Family Quality of Life Scale, a 5-point Likert scale ranging from "very dissatisfied" (1) to "very satisfied" (5). The mean overall FQoL score was 3.56 ± 0.79; the emotional well-being domain had the lowest score (2.98 ± 1.11) and showed significant differences between the other domains: family interaction (3.81 ± 0.89; p < 0.001), parenting (3.66 ± 0.89; p < 0.001), physical and material well-being (3.48 ± 0.83; p < 0.001), and disability-related support (3.75 ± 0.98; p < 0.001). Physical and material well-being was the second-lowest domain and was statistically different from the family interaction domain (p = 0.013). Lower FQoL satisfaction ratings were found in families with children who had difficulty getting along with people of the same age (t(51) = -3.193, p = 0.002; d = 1.019) and difficulty in living together on a day-to-day basis (t(51) = -3.060, p = 0.004; d = 0.888). These results highlight the importance of proper emotional support for the family, emphasizing the need to provide assistance not only for individuals with FXS but also for other family members. Besides, we advocate for the adoption of public policies that provide financial assistance to families and the implementation of the Brazilian Policy of Comprehensive Care for People with Rare Diseases.

How Families Manage the Complex Medical Needs of Their Children with MECP2 Duplication Syndrome

MECP2 duplication syndrome (MDS) is a rare, X-linked, neurodevelopmental disorder resulting from the duplication of the methyl-CpG-binding protein 2 (MECP2) gene. The clinical features of MDS include severe intellectual disability, global developmental delay, seizures, recurrent respiratory infections, and gastrointestinal problems. The aim of this qualitative study was to explore how the parents of children with MDS manage their child's seizures, recurrent respiratory infections, and gastrointestinal symptoms, and the impact on them as parents. The data were coded into three categories: (1) complex care needs in the home, (2) highly skilled caregivers, and (3) impact on caregivers and families. Complex 24 h care was required and parents developed complex skillsets to ensure that this was delivered well to their child. The provision of extensive complex medical care in the home had an impact on parent mental and physical health, family dynamics, and finances. This study captures the management of high-burden comorbidities in MDS at home. Investigations into how best to support caregiver wellbeing to reduce their stresses, whilst maintaining optimal child health and wellbeing, are needed.

Long time polysomnographic sleep and breathing evaluations in children with CDKL5 deficiency disorder

STUDY OBJECTIVES

CDKL5 deficiency disorder (CDD) is a rare developmental and epileptic encephalopathy, developing in the first months of life, caused by a mutation in the cyclin-dependent kinase-like 5 (CDKL5) gene. Children with CDD often have sleep (90%) and breathing disorders in wake (50%). Sleep disorders may have a significant impact emotional wellbeing and quality of life of caregivers of children with CDD and are challenging to treat. The outcomes of these features are unknown in children with CDD.

METHODS

We retrospectively evaluated sleep and respiratory function changes over 5-10 years in a small cohort of Dutch children with CDD, using video-EEG and/or polysomnography (3 × 24 h) and a parental questionnaire, the Sleep Disturbance Scale for Children (SDSC). The present study is a follow-up sleep and PSG study to evaluate if sleep and breathing disturbances persist in children with CDD previously studied.

RESULTS

Sleep disturbances persisted during the study period (5.5-10 years). All five individuals had long sleep latency (SL, range 32-174.5 min) and frequent arousals and awakenings (14-50/night), unrelated to apneas/seizures, corresponding to the SDSC findings. Low sleep efficiency (SE, 41-80%) was present and did not improve. In our participants, total sleep time (TST, 3h52min-7h52min) was short and remained so. Time in bed (TIB) was typical for children aged 2-8 years, but did not adjust with ageing. Low duration (4.8-17.4%) or even absent REM sleep persisted over time. No sleep apneas were noted. Central apneas due to episodic hyperventilation were reported during wakefulness in two of the five.

CONCLUSION

Sleep disturbances were present and persisted in all. The decreased REM sleep and sporadic breathing disturbances in wake may indicate failure of brainstem nuclei. Sleep disturbances can severely affect the emotional wellbeing and quality of life of the caregivers and the individuals with CDD and are challenging to treat. Hopefully our polysomnographic sleep data contribute to find the optimal treatment of the sleep problems in CDD patients.

Needs of informal caregivers of people with a rare disease: a rapid review of the literature

OBJECTIVES

Many people living with a rare disease (RD) are cared for by a family member. Due to a frequent lack of individual RD knowledge from healthcare professionals, the patient and their informal caregiver are frequently obliged to become 'experts' in their specific condition. This puts a huge strain on family life and results in caregivers juggling multiple roles in addition to unique caring roles including as advocate, case manager and medical navigator. We conducted a rapid review of literature reporting on the unmet needs of informal caregivers for people living with an RD. All searches were conducted on 14 September 2021, followed by a manual searches of reference lists on 21 September 2021.

SETTING

Searches were conducted in Medline, Embase, Web of Science, GreyLit and OpenGrey.

RESULTS

Thirty-five papers were included in the final review and data extracted. This rapid review presents several unmet needs identified by informal caregivers of persons with an RD. The related literature was organised thematically: caregiver burden, support through the diagnosis process, social needs, financial needs, psychological needs, information and communication needs and acknowledgement from healthcare professionals.

CONCLUSIONS

This review provides evidence that increased meaningful support is required for caregivers. Active engagement should be encouraged from this cohort in future research and awareness raised of the support available to improve the quality of life for families living with an RD. The unmet needs identified through this review will benefit people living with an RD, caregivers, healthcare professionals and policy makers.

Quality of life of Brazilian families who have children with Rubinstein-Taybi syndrome: An exploratory cross-sectional study

This exploratory cross-sectional study aimed to examine the family quality of life (FQoL) among 51 Brazilian families who have children with Rubinstein-Taybi syndrome, a rare genetic disorder. Data were collected using sociodemographic and clinical data forms, as well as the Beach Center FQoL Scale, a 5-point Likert scale ranging from "very dissatisfied" (1) to "very satisfied" (5). The average score of the overall FQoL was 3.93 ± 0.64. Families' scores were higher for family interaction (4.17 ± 0.76), parenting (4.13 ± 0.61), and disability-related support (4.08 ± 0.76) domains, and lower for the family's emotional well-being (3.31 ± 0.96) and physical/material well-being (3.76 ± 0.82) domains. Family income, attendance at religious services, presence of ocular abnormalities, and aggressive behavior explained 46.2% of the variance in the overall FQoL. In summary, FQoL seems to be anchored in aspects such as family interaction and the care of parents, and be negatively affected by emotional issues, physical, and material limitations. In this context, psychological assistance should be provided to both parents and siblings whenever indicated, for improving emotional well-being and increasing family resilience. Additionally, investments in social policies, services, and human and material resources are needed to improve the physical and material conditions of families, promote better health care, and therefore reduce the family burden.

Group intervention programs and their impact on well-being and quality-of-life for adults living with a rare or orphan disease - realist review of literature

PURPOSE

Adults living with a rare or orphan diseases (ROD) experience common psychosocial difficulties that are often poorly addressed in usual care. This realist literature review aims to inform the development, evaluation and implementation of evidence based group therapy programs adapted to shared needs of patients living with various ROD.

METHOD

The review is based on an analysis of Context-Mechanism-Outcome configurations. It included 21 primary studies published between 2010 and April 2022 and used a PRISMA process for study selection and inclusion.

RESULTS

Our results show that group psychosocial interventions can help reduce perception of symptoms and psychological impacts of disease, improve social functioning and support and quality of life in patients.

CONCLUSION

Group therapy programs seem promising for ROD-patients and should be considered within comprehensive treatment and support plans. However, more comprehensive studies of group therapies in context should aim to identify core active components of these interventions with ROD-patients. Implications for Rehabilitation:Rare or Orphan Diseases are varied, difficult to diagnose and have a major impact on all aspects of the patients' lives (physical, emotional, psychological, social, professional).Psychosocial support is a key but underdeveloped component to support the recovery trajectory for these patients.In this review of group interventions, we identified a few promising practices adaptable to patients living with Rare or Orphan Diseases (Acceptance and commitment therapy, cognitive behavioural therapies, psychoeducational programs).Patients who received psychosocial group interventions are likely to experience improvement in their quality of life.

Assessing the Burden on Caregivers of MECP2 Duplication Syndrome

BACKGROUND

MECP2 duplication syndrome (MDS) is a rare neurogenetic disorder characterized by severe neurodevelopmental disorder, refractory epilepsy, recurrent infections, and functional gastrointestinal problems. Because of the significant clinical problems and lifelong disability of children with this disorder we hypothesized that the burden on parents/caregivers of these children is significant. However, there are no reports of the impact on caregivers of individuals with MDS.

METHODS

We developed and validated a burden scale to investigate the challenges of caregivers of children and adults with MDS and identified factors contributing to the burden on caregivers. We developed a Health Insurance Portability and Accountability Act-compliant patient registry for families with MDS and delivered caregiver burden survey through the registry.

RESULTS

Of 237 completed surveys, 101 were eligible for the study. We identified increased levels of self-perceived anxiety, depression, and emotional exhaustion in caregivers that correlated with higher burden scores. Epilepsy was the only clinical feature that caused a higher burden in caregivers of individuals with MDS. In addition, a higher burden was found in Hispanic caregivers. The duration of care negatively correlated with burden score.

CONCLUSIONS

This is the first study to investigate the burden on caregivers of individuals with MDS and identify several factors contributing to increased burden. Addressing these concerns has the potential to improve the health of individuals with MDS and contribute to the well-being of their caretakers.

CDKL5 deficiency disorder: clinical features, diagnosis, and management

CDKL5 deficiency disorder (CDD) was first identified as a cause of human disease in 2004. Although initially considered a variant of Rett syndrome, CDD is now recognised as an independent disorder and classified as a developmental epileptic encephalopathy. It is characterised by early-onset (generally within the first 2 months of life) seizures that are usually refractory to polypharmacy. Development is severely impaired in patients with CDD, with only a quarter of girls and a smaller proportion of boys achieving independent walking; however, there is clinical variability, which is probably genetically determined. Gastrointestinal, sleep, and musculoskeletal problems are common in CDD, as in other developmental epileptic encephalopathies, but the prevalence of cerebral visual impairment appears higher in CDD. Clinicians diagnosing infants with CDD need to be familiar with the complexities of this disorder to provide appropriate counselling to the patients' families. Despite some benefit from ketogenic diets and vagal nerve stimulation, there has been little evidence that conventional antiseizure medications or their combinations are helpful in CDD, but further treatment trials are finally underway.

Mental health care for rare disease in the UK - recommendations from a quantitative survey and multi-stakeholder workshop

Background

Rare disease patients and carers report significant impacts on mental health but studies on UK populations have focussed on relatively few, specific conditions. Collectively rare conditions represent a substantial health burden, with an estimated 3.5 million affected individuals in the UK.

Method

We explored the impact on mental health of living with a rare condition, and experiences of health service support, through an online survey. The survey assessed the impact of specific experiences commonly reported by those affected by a rare condition through multiple choice questions and Likert scale items, and open text question boxes. Through a multi-stakeholder workshop that involved facilitated discussion of our findings with patients/carers, clinicians and a government advisor, we developed recommendations for policy and practice toward a more person-centred and integrated approach.

Results

Eligible responses came from 1231 patients and 564 carers. Due to their rare condition, the majority of respondents (> 90%) had felt worried/anxious; stressed; and /or low/depressed. Thirty-six percent of patients and 19% of carers had had suicidal thoughts.

Challenges that are particular to rare conditions and which negatively affect mental health included limited knowledge of the condition amongst healthcare professionals (88%), and not being believed or taken seriously by them.

Only 23% of respondents felt healthcare professionals considered mental and physical health as equally important. Almost half reported never having been asked about mental health by healthcare professionals. Our findings indicate that access to, and appropriateness of, professional psychological support needs to be improved. Peer group support is important but signposting is inadequate.

Our recommendations are for healthcare professionals to be supported to effectively and sensitively recognise and address patients’ and carers’ mental health needs; and for service level coordination of care to integrate professional psychological support with rare disease services.

Conclusion

Living with a rare disease substantially impacts mental health. Many of the drivers of poor mental health reflect issues specific to managing rare conditions. To meet UK government commitments, there should be a focus on empowering healthcare professionals who treat rare disease patients and on integration of mental health support with rare disease services.

Carer reported experiences: Supporting someone with a rare disease

This exploratory study aimed to gain an understanding of carer reported experiences derived specifically from persons caring for someone with a rare disease. The survey took place online on the SmartSurvey platform from November 2019 to January 2020. The facilitated workshop took place in Bangor Carnegie Library, Northern Ireland. To be eligible to participate in the online survey respondents had to be adults caring for someone with a rare disease. Fifty-seven respondents took part, 15.8% male, 84.2% female. Thirty-two attendees were part of the facilitated workshop. While carers reported several positive aspects of their caring role, the majority of comments highlighted challenges such as sub-optimal interactions with healthcare professionals, insufficient (or absent) emotional, psychological and social support, lack of financial support and lack of awareness of existing support services. It is important that strategies are put in place to ensure that carers are given the time they need to care for themselves, and that awareness is raised of what support options are available for carers of people with a rare disease(s) from health and social care providers, charities or support groups.

Gender Differences in Caring for Children with Genetic or Rare Diseases: A Mixed-Methods Study

As a factor in parenting stress, gender differences in caring for children with genetic or rare diseases warrant research attention; therefore, this study explored gender differences in parenting stress, health outcomes, and illness perceptions among caregivers of pediatric genetic or rare disease populations to improve the understanding of such gender differences. Applying a concurrent triangulation mixed-methods design, we conducted a questionnaire survey to assess study measures for 100 family caregivers (42 men and 58 women), which included a free-text response item to probe caregivers' subjective perceptions of the children's illness. The gender differences hypothesis was tested with statistics and the qualitative data about illness perception was analyzed by directed content analysis. Most female caregivers served as the primary caregivers and provided more caregiving, while they experienced significantly increased levels of parenting stress and depressive symptoms compared with male caregivers. Female caregivers perceived the conditions of their children's diseases to be highly symptomatic, with negative consequences and requiring disease control. By contrast, male caregivers had stronger perceptions regarding the negative effects of the disease on the children's quality of life. The gender discrepancy in viewpoints of illness perception sequence may contribute to female caregivers' higher levels of stress and depressive symptoms than males.

Sleep Disorders in Rett Syndrome and Rett-Related Disorders: A Narrative Review

Rett Syndrome (RTT) is a rare and severe X-linked developmental brain disorder that occurs primarily in females, with a ratio of 1:10.000. De novo mutations in the Methyl-CpG Binding protein 2 (MECP2) gene on the long arm of X chromosome are responsible for more than 95% cases of classical Rett. In the remaining cases (atypical Rett), other genes are involved such as the cyclin-dependent kinase-like 5 (CDKL5) and the forkhead box G1 (FOXG1). Duplications of the MECP2 locus cause MECP2 duplication syndrome (MDS) which concerns about 1% of male patients with intellectual disability. Sleep disorders are common in individuals with intellectual disability, while the prevalence in children is between 16 and 42%. Over 80% of individuals affected by RTT show sleep problems, with a higher prevalence in the first 7 years of life and some degree of variability in correlation to age and genotype. Abnormalities in circadian rhythm and loss of glutamate homeostasis play a key role in the development of these disorders. Sleep disorders, epilepsy, gastrointestinal problems characterize CDKL5 Deficiency Disorder (CDD). Sleep impairment is an area of overlap between RTT and MECP2 duplication syndrome along with epilepsy, regression and others. Sleep dysfunction and epilepsy are deeply linked. Sleep deprivation could be an aggravating factor of epilepsy and anti-comitial therapy could interfere in sleep structure. Epilepsy prevalence in atypical Rett syndrome with severe clinical phenotype is higher than in classical Rett syndrome. However, RTT present a significant lifetime risk of epilepsy too. Sleep disturbances impact on child's development and patients' families and the evidence for its management is still limited. The aim of this review is to analyze pathophysiology, clinical features, the impact on other comorbidities and the management of sleep disorders in Rett syndrome and Rett-related syndrome.

Piloting positive psychology resources for caregivers of a child with a genetic developmental and epileptic encephalopathy

Developmental and epileptic encephalopathies (DEEs) are chronic and life-threatening conditions, frequently with a genetic basis and infantile-onset. Caregivers often experience enduring distress adapting to their child's diagnosis and report a deficit of accessible psychological supports. We aimed to pilot a novel, empirically-driven suite of audio-visual positive psychology resources tailored for caregivers of children with a DEE, called 'Finding a Way'.

METHODS

We recruited caregivers through two paediatric hospital databases, and we also shared an invitation to the online questionnaire via genetic epilepsy advocacy organisations. The online questionnaire included a combination of validated, purpose-designed, and open-ended questions to assess the acceptability, relevance, and emotional impact of the resources among caregivers.

RESULTS

167 caregivers from 18 countries reviewed the resources, with 56 caregivers completing over 85% of the evaluation. Caregivers rated the resources as highly acceptable and relevant to their experiences. In both the quantitative and qualitative data, caregivers reported that the resources normalised their emotional experiences and provided helpful suggestions about managing their personal relationships, seeking support and accepting help from others. Frequently reported emotional responses after viewing the resources included feeling "comforted", "hopeful", "connected" and "reassured". Suggestions for improvement included, expanding the suite of resources and embedding the resources with links to specialised psychological services.

CONCLUSION

'Finding a Way' is a novel codesigned suite of audio-visual positive psychology resources tailored for caregivers of children with DEEs. Our results suggest that 'Finding a Way' is acceptable to caregivers and may contribute towards enhanced emotional adaptation and coping.

Influences on the trajectory and subsequent outcomes in CDKL5 deficiency disorder

OBJECTIVE

The study investigated the effect of seizure and medication burden at initial contact with the International CDKL5 Disorder Database on subsequent development and clinical severity and compared quality of life among those whose development progressed, remained stable, or regressed between baseline and follow-up.

METHODS

The effects of seizure and medication burden at baseline (high or low) on the CDKL5 Disorder Severity Scores and CDKL5 Developmental Score (CDS) at follow-up were assessed using linear and negative binomial regressions, respectively, with adjustment for age at baseline, gender, and follow-up duration with and without genotype. Seizure and medication burden were defined by average daily seizure count (high, ≥5/day; low, <5/day) and number of antiseizure medications (high, ≥3/day; low, <3/day), respectively. The effects of change in CDS over time (improved, stable, or deteriorated) on Quality of Life Inventory-Disability (QI-Disability) total and domain scores at follow-up were assessed in those aged at least 3 years at follow-up using linear regression models with adjustment for baseline CDS, gender, and follow-up duration.

RESULTS

The expected follow-up CDS was lower for individuals with high compared to low seizure burden at baseline (β = -.49, 95% confidence interval [CI] = -.84 to -.13). The average total QI-Disability score was 5.6 (95% CI = -.2 to 11.5) points higher among those with improved compared with stable or deteriorating CDS and 8.5 (95% CI = 3.1-13.8) points lower for those with deteriorating compared to stable or improved CDS.

SIGNIFICANCE

Our finding that later development showed slight improvement in those with better earlier seizure control even after adjustment for genotype suggests that the trajectory for an individual child is not necessarily predetermined and could possibly be influenced by optimal seizure management. This has implications for children's quality of life.

Impact of developmental and epileptic encephalopathies on caregivers: A literature review

OBJECTIVES

Developmental and epileptic encephalopathies (DEEs) are rare neurodevelopmental disorders characterized by early-onset seizures and numerous comorbidities. Due to the complex requirements for the care of a child with a DEE, these disorders would be expected to impact health-related quality of life (HRQL) for caregivers as well as for patients. The objective of this literature review was to describe the impact of DEEs on the HRQL, emotional wellbeing, and usual activities (social, work, relationships, etc.) of caregivers, including the wider impact on other family members such as siblings.

METHODS

A literature search was conducted in May 2020 using MEDLINE® and Embase® databases. Quantitative and qualitative studies were identified using search terms related to family, disease type (including >20 specific DEEs), and quality of life/methodology. Each study was assessed for relevance and was graded using customized critical appraisal criteria. Findings from studies that were given the highest quality ratings were summarized and used to develop a conceptual model to illustrate the complex impact of DEEs on caregiver HRQL.

RESULTS

Sixty-seven relevant studies were identified, of which 39 (27 quantitative, 12 qualitative) met the highest appraisal criteria. The studies recruited caregivers of patients with one of eight individual DEEs, or pediatric intractable or refractory epilepsy. Most studies reported negative impacts on HRQL and emotional wellbeing in caregivers. The wide-ranging impact of a DEE was highlighted by reports of negative effects on caregivers' physical health, daily activities, relationships, social activities, leisure time, work, and productivity. Factors that influenced the perceived impact included demographic characteristics (e.g., child's age, living arrangements, family income) and clinical factors (e.g., feeding or sleep difficulties, disease severity). Few studies evaluated the impact on siblings.

CONCLUSIONS

There is evidence that DEEs can impact HRQL and emotional wellbeing and can limit usual activities for the primary caregiver and their wider family. However, no research was identified regarding many individual DEEs, and only limited research assessed the impact on different family members with most studies focusing on mothers. Further research is required to understand the influence of certain factors such as the age of the patient, disease severity, and seizures on caregiver burden. Furthermore, the review highlighted the lack of appropriate measurement tools to assess caregiver HRQL in this population.

Current neurologic treatment and emerging therapies in CDKL5 deficiency disorder

Background

CDKL5 deficiency disorder (CDD) is associated with refractory infantile onset epilepsy, global developmental delay, and variable features that include sleep, behavioral disturbances, and movement disorders. Current treatment is primarily symptom-based and informed by experience in caring for this population.

Methods

We describe medication and non-medication approaches to treatment of epilepsy and additional key neurologic symptoms (sleep disturbances, behavioral issues, movement disorders, and swallowing dysfunction) in a cohort of 177 individuals meeting criteria for CDD, 154 evaluated at 4 CDKL5 Centers of Excellence in the USA and 40 identified through the NIH Natural History Study of Rett and Related Disorders.

Results

The four most frequently prescribed anti-seizure medications were broad spectrum, prescribed in over 50% of individuals. While the goal was not to ascertain efficacy, we obtained data from 86 individuals regarding response to treatment, with 2-week response achieved in 14–48% and sustained 3-month response in 5–36%, of those with known response. Additional treatments for seizures included cannabis derivatives, tried in over one-third of individuals, and clinical trial medications. In combination with pharmacological treatment, 50% of individuals were treated with ketogenic diet for attempted seizure control. Surgical approaches included vagus nerve stimulators, functional hemispherectomy, and corpus callosotomy, but numbers were too limited to assess response. Nearly one-third of individuals received pharmacologic treatment for sleep disturbances, 13% for behavioral dysregulation and movement disorders, and 43% had gastrostomy tubes.

Conclusions

Treatment for neurologic features of CDD is currently symptom-based and empiric rather than CDD-specific, though clinical trials for CDD are emerging. Epilepsy in this population is highly refractory, and no specific anti-seizure medication was associated with improved seizure control. Ketogenic diet is commonly used in patients with CDD. While behavioral interventions are commonly instituted, information on the use of medications for sleep, behavioral management, and movement disorders is sparse and would benefit from further characterization and optimization of treatment approaches. The heterogeneity in treatment approaches highlights the need for systematic review and guidelines for CDD. Additional disease-specific and disease-modifying treatments are in development.

CDKL5 deficiency disorder in males: Five new variants and review of the literature

The X-linked Cyclin-Dependent Kinase-Like 5 (CDKL5) gene encodes a serine-threonine kinase highly expressed in the developing brain. Loss of function of CDKL5 is pointed out to underlie the CDKL5 Deficiency Disorder (CDD), an X-linked dominant disease characterized by early-onset epileptic encephalopathy and developmental delay, usually affecting females more than males. To the best to our knowledge, only 45 males with CDD have been reported so far. Type and position of CDKL5 variants with different impact on the protein are reported to influence the clinical presentation. X-chromosome inactivation occurring in females and post-zygotic mosaicism in males are also believed to contribute to this variability. Based on these issues, genotype-phenotype correlations are still challenging. Here, we describe clinical features of five additional affected males with unreported CDKL5 variants, expanding the molecular spectrum of the disorder. We also reviewed the clinical profile of the previously reported 45 males with molecularly confirmed CDD. Severe developmental delay, cortical visual impairment, and early-onset refractory epilepsy characterize the CDD picture in males. By assessing the molecular spectrum, we confirm that germ-line truncating CDKL5 variants, equally distributed across the coding sequence, are the most recurrent mutations in CDD, and cause the worsen phenotype. While recurrence and relevance of missense substitutions within C-terminal remain still debated, disease-causing missense changes affecting the N-terminal catalytic domain correlate to a severe clinical phenotype. Finally, our data provide evidence that post-zygotic CDKL5 mosaicism may result in milder phenotypes and, at least in a subset of subjects, in variable response to antiepileptic treatments.

Variables related to the quality of life of families that have a child with severe to profound intellectual disabilities: A systematic review

Background

Family quality of life (FQoL) of families that have a child with severe to profound intellectual disabilities (SPID) is an important and emerging concept, however, related variables are inconclusive.

Aim

To gain a better understanding of variables related to the FQoL of families that have a child with SPID, variables related to the FQoL of families that have a child with intellectual disabilities (ID) were systematically reviewed.

Methods and procedures

A search strategy was performed in five databases. Critical appraisal tools were employed to evaluate the quality of both quantitative and qualitative studies. Data extraction and synthesis occurred to establish general study characteristics, variables, and theoretical concepts. Variables were categorised into four key concepts of the FQoL: systemic concepts, performance concepts, family-unit concepts and individual-member concepts.

Outcomes and results

A total of 40 studies were retrieved with 98 variables. Quality scores ranged from 7 to 13 (quantitative) and 5 to 13 (qualitative) out of 13 and 14 points, respectively. Five out of the 40 studies (13%) focused on individuals with SPID. Variables related positively or negatively to the FQoL, and were categorised within systemic concepts (n = 3); performance concepts (n = 11); family-unit concepts (n = 26); and individual-member concepts (n = 58).

Conclusions and implications

Several variables were found to be (inter)related to the FQoL of families that have a child with ID. A contrasting picture emerged regarding the impact of a disability in relation to transitional phases. However, studies which include families of children with SPID were minimal, therefore, it remained ambiguous to what extent the identified variables apply to these families.

Being the Pillar for Children with Rare Diseases-A Systematic Review on Parental Quality of Life

Parents caring for children with rare diseases fear the long-term progression of the child’s disease. The current study aims to systematically investigate the quality of life (QoL) in parents of children with different rare diseases. We performed a systematic literature search including quantitative studies on QoL of parents caring for children and adolescents with rare diseases in five databases (APA PsycArticles, APA PsycInfo, MEDLINE, PSYNDEXplus, and PubMed) published between 2000–2020. Of the 3985 titles identified, 31 studies met the inclusion criteria and were selected for narrative review. Studies were included if they investigated predictors of parental QoL or reported QoL compared to normative samples, parents of healthy children, or children with other chronic diseases. We used the Newcastle–Ottawa Scale to assess methodological quality. The systematic review revealed that parents of children with rare diseases experience reduced QoL compared to parents with healthy children and norm values. Psychosocial factors, beyond disease-specific predictors, were shown to influence parental QoL substantially and may thus present an essential aspect within interventions for this highly burdened group. Health care professionals should consider and address the impairment of parental QoL due to the child’s rare disease. We discuss insights into existing research gaps and improvements for subsequent work.

Exploring quality of life in individuals with a severe developmental and epileptic encephalopathy, CDKL5 Deficiency Disorder

BACKGROUND

CDKL5 Deficiency Disorder (CDD) is a rare genetic disorder caused by a mutation in the cyclin-dependent kinase-like 5 (CDKL5) gene. It is now considered to be a developmental and epileptic encephalopathy because of the early onset of seizures in association with severe global delay. Other features include cortical visual impairment, sleep and gastro-intestinal problems. Progress in clinical understanding, especially regarding the spectrum of functional ability, seizure patterns, and other comorbidities was initially slow but accelerated in 2012 with the establishment of the International CDKL5 Database (ICDD). Our aim was to use this data source to investigate quality of life (QOL) and associated factors in this disorder.

METHOD

A follow-up questionnaire was administered in 2018 to parents of children registered with the ICDD who had a pathogenic CDKL5 variant. QOL was assessed using QI Disability, an instrument, specifically developed to measure total and specific domains of QOL (physical health, positive emotions, negative emotions, social interaction, leisure and the outdoors (leisure) and independence) in children with intellectual disability. Associations with functional abilities, physical health, mental health and family factors were investigated, initially using univariate analyses followed by multivariate analyses for each of these groups with a final composite model which included the important variables identified from previous models.

RESULTS

Questionnaires were returned by 129/160 families with a child aged >3 years. Functional impairment, including lack of ability to sit, use hands and communicate had the greatest adverse impact on QOL. There were also some relationships with major genotype groupings. Individuals using three or more anti-epileptic medications had poorer QOL than those on one or no medication, particularly in the physical health domain. There was also variation by geographical region with those living in North America typically having the best QOL and those living in middle or lower income countries poorer QOL.

CONCLUSION

Although lower functional abilities were associated with poorer quality of life further research is needed to understand how environmental supports might mitigate this deficit. Comprehensive care and support for both the child and family have important roles to play in helping families to thrive despite the severity of CDD.

Quality of Life and Concerns in Parent Caregivers of Adult Children Diagnosed with Intellectual Disability: A Qualitative Study

Background: Previous studies have confirmed that parenting a child diagnosed with an intellectual disability (ID) can negatively affect the parents’ quality of life in several dimensions. However, fewer have assessed its impact years after the initial diagnosis. The objective of this work was to carry out an in-depth analysis of the current quality of life and concerns of both mothers and fathers of adults diagnosed with ID, having as a reference the moment of the diagnosis. Methods: 16 parents of adult children with ID were evaluated using a semi-structured interview format. A thematic qualitative analysis was carried out by employing ATLAS.ti software. Results: The results suggested that both the emotional and physical well-being of parents, as well as their interpersonal relationships, had declined. In addition, the multiple life changes that had occurred over the time considered in this study, as well as day-to-day worries, had prevented improvements in their quality of life. Conclusions: Several dimensions of the parents’ quality of life were affected years after a child is diagnosed with ID. These included poor physical and psychological health, economic difficulties, lack of social and family support, and lack of time for self-care.

The Spanish Family Quality of Life Scales under and over 18 Years Old: Psychometric Properties and Families' Perceptions

BACKGROUND

Family quality of life (FQoL), just like individual quality of life, has become a priority outcome in the policies and services received by persons with intellectual and developmental disabilities (IDD) and their families. Conceptualizing, measuring, and theorizing FQoL has been the object of investigation in recent decades. The goal of this paper is to present a revision of the Spanish Family Quality of Life Scales, the CdVF-E < 18 and the CdVF-E >18, and describe the FQoL of Spanish families with a member with IDD.

METHODS

The sample included a total of 548 families with a member under 18 years old and 657 families with a member over 18. Based on an Exploratory Factor Analysis (EFA) firstly and a Confirmatory Factor Analysis (CFA) secondly, the two scales' psychometric properties were explored.

RESULTS

The CdVF-ER < 18 and the CdVF-ER > 18 comprise 5 dimensions, containing 35 and 32 items, respectively, and they show good validity and reliability. The families obtained a high FQoL score, although some differences exist between the dimensions on which families with children under and over 18 score highest and lowest.

CONCLUSION

The characteristics of the revised scales facilitate their use by professionals, administrations, and services.

Behavioral phenotype and sleep problems in SATB2-associated syndrome

AIM

To determine the nature and frequency of behavioral phenotypes and sleep disturbances in individuals with SATB2-associated syndrome (SAS).

METHOD

The Strengths and Difficulties Questionnaire (SDQ) and an age-appropriate sleep questionnaire were distributed to the parents of individuals with SAS. All scores were compared to available normative data.

RESULTS

Thirty-one individuals completed the assessment (18 females, 13 males; mean age 7y 4mo [SD 4y 1mo], range 2-16y). Individuals with SAS had significantly higher Total Difficulty scores than the normative sample (14.9 [SD 5.8] vs 7.1 [SD 5.7], p<0.001). A high frequency of emotional problems (22.6% vs 8%, p=0.01), peer problems (48.4% vs 10%, p<0.001), hyperactivity (48.4% vs 9%, p<0.001), and low prosocial behaviors (45.2% vs 9%, p<0.001) contribute to the behavioral profile in SAS. Concurrent sleeping difficulties were also frequently identified. Ten individuals in the 5 to 15 years age range had at least one sleep disorder (mean Sleep Disturbance Scale for Children total score 40.9 [SD 8.4] vs 35.1 [SD 7.7], p<0.001).

INTERPRETATION

With previous limited available objective neurobehavioral data on the SAS population, we reported evidence of high-risk for a broad spectrum of burdensome behavioral phenotype and concurrent sleeping difficulties, the latter being particularly prevalent during early childhood. Routine assessment and treatment for behavioral issues and sleep problems is recommended.

WHAT THIS PAPER ADDS

Emotional and peer problems, hyperactivity, and low prosocial behavior are common in SATB2-associated syndrome. The Strength and Difficulties Questionnaire Total Difficulty scores are atypical in nearly half of individuals. Behavioral difficulties are perceived as burdensome to over half of the parents. Nearly half of individuals have at least one sleep disorder. Sleep-wake transition disorders were most common.

Consensus guidelines on managing Rett syndrome across the lifespan

BACKGROUND

Rett syndrome (RTT) is a severe neurodevelopmental disorder with complex medical comorbidities extending beyond the nervous system requiring the attention of health professionals. There is no peer-reviewed, consensus-based therapeutic guidance to care in RTT. The objective was to provide consensus on guidance of best practice for addressing these concerns.

METHODS

Informed by the literature and using a modified Delphi approach, a consensus process was used to develop guidance for care in RTT by health professionals.

RESULTS

Typical RTT presents early in childhood in a clinically recognisable fashion. Multisystem comorbidities evolve throughout the lifespan requiring coordination of care between primary care and often multiple subspecialty providers. To assist health professionals and families in seeking best practice, a checklist and detailed references for guidance were developed by consensus.

CONCLUSIONS

The overall multisystem issues of RTT require primary care providers and other health professionals to manage complex medical comorbidities within the context of the whole individual and family. Given the median life expectancy well into the sixth decade, guidance is provided to health professionals to achieve current best possible outcomes for these special-needs individuals.

Qualidade de vida de famílias de filhos com deficiência intelectual moderada

RESUMO Objetivo Investigar a qualidade de vida familiar (QVF) entre famílias brasileiras que têm filhos com deficiência intelectual (DI) moderada. Métodos Estudo transversal, realizado com 50 famílias com filhos com DI moderada de São Carlos, São Paulo, Brasil. Os dados foram coletados por meio de formulários, com informações sociodemográficas, os índices de funcionalidade de Barthel e de Lawton & Brody e a Escala de Qualidade de Vida Familiar do Beach Center. Resultados Os domínios mais fortemente correlacionados com a QVF total foram “interação familiar” (r = 0,870; p < 0,001) e “cuidado dos pais com os filhos” (r = 0,845; p < 0,001). Não houve diferenças na distribuição da QVF em relação às variáveis sociodemográficas investigadas. Observou-se correlação moderada (r = 0,326) e significativa (p = 0,021) entre o índice de funcionalidade de Lawton & Brody e a QVF. O modelo de regressão linear ajustado explicou 10,6% da variabilidade encontrada na QVF (p = 0,021) e mostrou que o aumento de uma unidade no valor do índice de Lawton & Brody representou aumento de 0,092 na QVF. Conclusão A QVF das famílias investigadas encontra-se aquém de outras amostras internacionais. Ações clínicas que fortaleçam o diálogo e a coesão familiar e a construção de um plano terapêutico individualizado podem ser meios efetivos de ajuda a essas famílias.

Longitudinal effects of caregiving on parental well-being: the example of Rett syndrome, a severe neurological disorder

Little longitudinal research has examined parental well-being in those with a child with specific genetic developmental disorder although the associated severe neurological impairments and multiple physical comorbidities likely place substantial burden of caregiving on the parent. We aimed to examine longitudinally the well-being of parents of individuals included in the Australian Rett Syndrome Database over the period from 2002 to 2011 using the Short Form 12 Health Survey. Residential remoteness, the child being a teenager at baseline, having frequent sleep disturbances or behavioural problems, and the type of MECP2 gene mutation were each associated with later poorer parental physical well-being scores. Being a single parent or on a low income was also associated with later poorer physical well-being, while the child having enteral feeding was associated with later poorer emotional well-being. Both the physical and emotional well-being of the parent improved if the child was living in out-of-home care. Our findings suggest that some opportunities do exist for clinicians to help optimise parental well-being. Being alert to the possibility and need for management of a child's sleep or emotional disturbance is important as is awareness of the additional likely parental burden as the child moves through adolescence into early adulthood and their need for additional support at that time. However, the findings also highlight the complex nature of parental well-being over time in parents of children with a severe neurological disorder and how they may be affected by a range of inter-related family and child factors.

Maternal and paternal quality of life in children with epilepsy: Who is affected more?

INTRODUCTION

This study aimed to evaluate and compare parental quality of life (QoL), anxiety, and depression in mothers and fathers of children with epilepsy (CWE).

MATERIAL AND METHODS

Thirty-three mothers and 33 fathers of 33 CWE (aged 1-16 years) completed the World Health Organization Quality of Life-Brief Form (WHOQOL-BREF), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI) questionnaires. Scores for the questionnaires were compared for 36 mothers and 36 fathers of 36 healthy children (aged 1-16 years). The control group consisted of hospital staff who had healthy children.

RESULTS

Mothers of CWE had significantly lower scores for the environmental domain of the WHOQOL-BREF, BDI, and BAI questionnaires compared with mothers of healthy children (p < 0.05), while fathers showed no significant difference (p > 0.05). Furthermore, mothers of CWE had significantly lower scores for the psychological domain of the WHOQOL-BREF compared with fathers (p < 0.05). The environmental domain of the WHOQOL-BREF questionnaire was negatively correlated with the number of children for all parents (r = -0.342, p = 0.005), and the BAI and BDI scales were positively correlated with the number of children (r = 0.386, p = 0.001; r = 0.395, p = 0.001, respectively).

CONCLUSION

Mothers of CWE showed lower scores for the psychological domain in QoL analysis compared with fathers of CWE, as well as decreased emotional wellbeing and lower QoL compared with mothers of healthy children. These results reveal that parents of CWE with a larger family size are more affected and that mothers of CWE are more affected. The reasons for these findings and possible interventions that might improve QoL, particularly in mothers with CWE, require further research.

Cannabis for refractory epilepsy in children: A review focusing on CDKL5 Deficiency Disorder

Severe paediatric epilepsies such as CDKL5 Deficiency Disorder (CDD) are extremely debilitating, largely due to the early-onset and refractory nature of the seizures. Existing treatment options are often ineffective and associated with a host of adverse effects, causing those that are affected to seek alternative treatments. Cannabis based products have attracted significant attention over recent years, primarily driven by reports of miraculous cures and a renewed public preference for 'natural' therapies, thus placing intense pressure on health professionals and the government for regulatory change. This study provides a comprehensive overview of the potential role for cannabis in the treatment of CDD. Key areas discussed include the history, mechanism of action, efficacy and safety of cannabis based preparations as well as the burden related to CDD. The evidence supports the use of cannabinoids, especially cannabidiol, in similar forms of refractory epilepsy including Dravet and Lennox-Gastaut syndromes. Evidence for cannabinoids specifically in CDD is limited but growing, with multiple anecdotal reports and an open-label trial showing cannabidiol to be associated with a significant reduction in seizure activity. This review provides the first comprehensive overview of the potential role for cannabis based preparations in the treatment of CDD and provides justification for further clinical and observational research.

Quality of life related to clinical features in patients with Rett syndrome and their parents: a systematic review

Patients with a neurodevelopmental disorder such as Rett syndrome (RS), as well as their families, have complex needs that affect their quality of life (QoL). Therefore, both families and patients with RS must be provided with multidisciplinary health care that can identify the clinical features that most affect their QoL and mental health risks. The main objective of this paper is to provide a comprehensive overview of the QoL subdimensions of families affected by RS, including both the parents and children. We conducted a systematic review, following PRISMA criteria, of the data in the PubMed, PsycINFO, Cuiden, and LILACS databases. The results indicated that when considering the family as a whole, RS equally affects the physical and psychological QoL dimensions; the next most affected was the social dimension. According to parents' reports, seizures are one of the main factors that decreases their QoL. Thus, from a clinical point of view, controlling seizure activity of children with RS is the main way of improving the QoL of their parents. Interventions in patients affected by RS should be based on the improvement of visual contact and concentration, reducing somnolence, and increasing mobility. The subdimensions of QoL that were most affected in parents of girls with RS were those related to mental health and feelings of well-being.

Care-related quality of life in caregivers of children with drug-resistant epilepsy

BACKGROUND

Epilepsy in children negatively impacts on caregiver quality of life (QOL). The study aimed to evaluate the relationships between patient factors [demographics, clinical factors, health-related quality of life (HRQL)], contextual factors (socio-economic factors), caregiver mood, and caregiver QOL, and whether family factors mediate the relationship between patient HRQL and caregiver QOL.

METHODS

Children aged 4-18 years with medically intractable epilepsy were enrolled. Patient demographics, clinical data, patient HRQL [measured using Quality of Life in Childhood Epilepsy Questionnaire (QOLCE)], socio-economic factors, caregiver anxiety and depression, and family factors (adaptation, resources and demands) were assessed. Caregiver QOL was measured using CarerQol, which evaluates care-related QOL, incorporating the negative and positive effects of caregiving.

RESULTS

One hundred and eighty-one children were studied. In bivariable regression analysis, higher patient HRQL (QOLCE) (β = 0.54, p < 0.001) and household income (β = 10.49, p = 0.019) were associated with higher caregiver QOL. Higher depression (β = - 2.48, p < 0.001) and anxiety (β = - 2.04, p < 0.001) were associated with lower caregiver QOL. Seizure severity and other socio-economic factors did not influence caregiver QOL (all p > 0.05). In multivariable regression analysis, higher QOLCE (β = 0.21, p = 0.001), lower depression (β = - 1.07, p < 0.001) and lower anxiety (β = - 1.19, p < 0.001) were associated with higher caregiver QOL. Family demands and resources moderated the relationship between patient HRQL and caregiver QOL.

CONCLUSIONS

Patient HRQL and caregiver mood were more important correlates of caregiver QOL than seizure severity in medically intractable epilepsy. The findings are significant in delineating variables (caregiver mood and family factors) that are potentially modifiable, and show promise for improving caregiver QOL.

A systematic review of quality of life in parents of children with epilepsy

OBJECTIVES

This systematic review aimed to 1) describe the quality of life (QOL) of parents of children with childhood-onset epilepsy (CWE), 2) identify factors associated with parental QOL, and 3) evaluate the association between parents' QOL and children's psychological well-being.

METHODS

We conducted a comprehensive search of MEDLINE, EMBASE, and PsycINFO and conducted forward and backward citation tracking. A total of 15 articles met inclusion criteria. Parents' QOL was compared with population norms, healthy controls, and parents of children with other chronic conditions. Factors associated with parental QOL were systematically evaluated.

RESULTS

Heterogeneity in study design and reporting prevented a meta-analytic synthesis of results. The majority of studies found that parents of CWE had poorer QOL relative to healthy controls or population norms and similar QOL as parents of children with other chronic conditions. In addition, poorer parental QOL was consistently associated with greater parental anxiety and depressive symptoms and poorer socioeconomic status and child QOL. Mothers had poorer QOL relative to fathers. Seizure control was not consistently associated with parental QOL. Results highlight the impact of family environment and psychosocial factors.

SIGNIFICANCE

This review suggests that parents of CWE have compromised QOL. The results are in line with previous research showing the interdependent nature of psychosocial and medical factors, with psychosocial factors playing a critical role in child and parental QOL and well-being. Interventions targeting the family unit are warranted, and healthcare providers should be aware of the bidirectional relationship of epilepsy, family environment, and child/parent health and well-being.

Sleep disturbances in Rett syndrome: Impact and management including use of sleep hygiene practices

Sleep disturbances are debilitating for individuals with Rett syndrome (RTT) and their families yet the evidence base for management is poor. We investigated management strategies and their relationships with sleep problems. Data were provided by 364/461 (79%) families with a child with RTT and registered with the International RTT Phenotype Database. Logistic regression models were used to investigate relationships between impacts of sleep problems on the child and family with age group, mutation type, medication type, and sleep hygiene score. Linear regression models were used to estimate the association of disorders of initiating and maintaining sleep (DIMS) with age group, mutation type, medication type, and sleep hygiene. Among those who ever had difficulty falling asleep or night waking, use of any medication was associated with higher odds of moderate/major impact sleep problems (relative to minor/no impact) for the affected child and the family, as well as higher DIMS scores, when compared with the no treatment/nonmedication group accounting for the effects of age, mutation type, and sleep hygiene score. Better use of sleep hygiene practices was associated with lower odds of moderate/major impact on the family (odds ratio 0.60, 95% confidence intervals [CIs] 0.37, 0.98) and lower DIMS scores (geometric mean ratio 0.86, 95%CI 0.80, 0.92) compared with poorer use after adjusting for covariates. Attention to sleep hygiene remains an important management strategy for sleep problems in RTT. Further prospective research is required to investigate efficacy of pharmaceutical treatments.

Effect of Epilepsy on Families, Communities, and Society

The effect of epilepsy extends beyond those with the diagnosis and impacts families, communities and society. Caregiver and sibling quality of life is often negatively affected by frequent seizures, comorbid behavioral and sleep disorders and stigma surrounding the diagnosis. Furthermore, the negative effects can be magnified by individual coping styles and resources available to families of those with epilepsy. Beyond the family and immediate caregivers, epilepsy affects local communities by drawing additional resources from education systems. The direct costs of caring for an individual with epilepsy and the indirect costs associated with decreased productivity place financial strain on individuals and health care systems throughout the world. This review details factors affecting family and caregiver quality of life and provides several approaches through which health care providers may address these concerns. Furthermore, we examine the financial effect of epilepsy on society and review emerging strategies to lessen health care use for individuals with epilepsy.
