Assessment of child neurology outpatients with headache, dizziness, and fainting

The Relationship Between Vertigo/Dizziness and Somatoform Complaints: A Systematic Review

To systematically synthesize published literature on somatoform complaints as psychological factors in vertigo/dizziness to determine the characteristics of comorbidities, relationships and causality. Following PRISMA guidelines, systematic searches of PubMed, WOS, and Cochrane Library databases and manual follow-up reference searches were performed for articles published in English up to 2021. All original research studies and retrospective or prospective studies focusing on the relationship between vertigo/dizziness and somatoform complaints/somatization were systematically retrieved. Studies that did not include data on the association between somatoform complaints/somatization and vertigo/dizziness were excluded, as were reviews, comments, case reports, editorials, letters, and practice guidelines. Extracted data included research type, number of participants, assessment tools for vertigo/dizziness and somatoform complaints/somatization, statistical methods, and the main results. The quality of included studies was evaluated. Records identified through database searching n = 1238. After removing duplicates and unrelated articles based on abstract and title search, 155 articles recorded as relevant. Except for the 5 articles, title and abstract of all records screened and 88 of them excluded. Critically evaluating those full texts, 28 studies included. The present study highlights the relationship between the vertigo/dizziness and somatoform complaints/somatization. It is determined that somatoform complaints of the individuals suffering from vertigo/dizziness is highly prevelant and some other factor such as personality characteristics or accompanying psychopathology have affect on the prevelance. The main results of all reviewed studies emphasize the requirement for assessment and intervention of vertigo/dizziness, in collaboration with the department of psychiatry.

The Relationship Between Parental and Family Functioning and Post-Concussive Symptoms After Pediatric Mild Traumatic Brain Injury: A Scoping Review

This scoping review aimed to address the following questions: (1) Does mild traumatic brain injury (mTBI) result in more parental distress or poorer family functioning than other injuries? (2) Does pre-injury or acute parental distress and family functioning predict post-concussive symptoms (PCS) after mTBI? and (3) Do acute PCS predict later parental distress and family functioning? The subjects of this review were children/adolescents who had sustained an mTBI before age 18 and underwent assessment of PCS and parent or family functioning. MEDLINE®, PsycInfo, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Embase, and CENTRAL databases were searched to identify original, empirical, peer-reviewed research published in English. PCS measures included parent- and child-reported symptom counts and continuous scales. Parent and family measures assessed parental stress, psychological adjustment, anxiety, psychiatric history, parent-child interactions, family burden, and general family functioning. A total of 11,163 articles were screened, leading to the inclusion of 15 studies, with 2569 participants (mTBI = 2222; control = 347). Collectively, the included articles suggest that mTBI may not result in greater parental distress or poorer family functioning than other types of injuries. Pre-injury or acute phase parental and family functioning appears to predict subsequent PCS after mTBI, depending on the specific family characteristic being studied. Early PCS may also predict subsequent parental and family functioning, although findings were mixed in terms of predicting more positive or negative family outcomes. The available evidence suggests that parent and family functioning may have an important, perhaps bidirectional, association with PCS after pediatric mTBI. However, further research is needed to provide a more thorough understanding of this association.

Benign paroxysmal positional vertigo in a young child

A girl in her early childhood presented to a regional otolaryngology outpatient clinic with classic signs of benign paroxysmal positional vertigo (BPPV). She reported episodic dizziness when rolling in a supine position. She did not convey any other associated audiovestibular symptoms. A bedside Dix-Hallpike test confirmed geotropic rotational nystagmus indicative of lateral canal BPPV. Due to her young age, limited communicative abilities and concerns for more sinister underlying pathology, a complete neurological examination, MRI and pure tone audiometry were performed. After two sessions of Epley's manoeuvre, she was symptom-free. At her 3-month follow-up, the patient denied any recurrent episodes of vertigo.

Neurofeedback as neuroempowerment technique for affective regulation and interoceptive awareness in adolescence: preliminary considerations applied to a psychogenic pseudosyncope case

Revisions of classical models of acute stress response spectrum and defence cascade process might represent a valuable background for the interpretation of the link between affective reactions, traumatic experiences, and Psychogenic pseudosyncope (PPS) events in childhood and across the lifespan. Indeed, associations between subjective emotional life, early exposure to distressing and/or traumatic events, and PPS have fuelled a debate on potential causes of occurrence and recurrence of such a peculiar clinical manifestation. At the same time, such background suggests that empowering stress management and affective regulation skills could be the target for neurorehabilitation interventions aiming at reducing the severity of symptomatology and/or improving awareness and management of pseudosyncopal spells. Specifically, neuro/biofeedback-based empowerment of self-regulation skills, associated to an increased interoceptive increased awareness, could be a promising complement to classical psychological therapies. Starting from the presentation of a paediatric PPS clinical case, the present work discusses the relevance of assessing affective appraisal and autonomic reactivity in individuals suffering from PPS episodes and introduces a novel potential neuroempowerment protocol aimed at improving self-regulation and stress management skills in adolescence based on a combined neurofeedback and embodied-awareness intervention. By capitalizing available evidence of the effects of neuromodulation and embodied practices on self-awareness/regulation across the life-span, the proposed protocol is based on neurofeedback-supported affective management training, as well as both contemplative and informal awareness exercises devised to be appealing and challenging even for younger patients.

(Doctor…My child keeps falling over) unexpected MRI findings in children with history of frequent falls and dizziness: a case series

Frequent falls and dizziness are common complaints in children. These symptoms can be caused by wide range of underlying pathologies including peripheral vestibular deficits, cardiac disease, central lesions, motor skills delay and psychogenic disorders. We report three paediatric cases who presented with complaints of repeated falls and imbalance. MRI scan revealed underlying brain lesions (frontal lobe arteriovenous malformation, exophytic brain stem glioma and cerebellomedullary angle arachnoid cyst with cerebellar tonsillar ectopia). By reporting these cases, we would like to emphasise the importance of a thorough assessment of children with similar symptoms by detailed clinical history, physical examination and maintaining low threshold for investigations, including radiological imaging. Taking in consideration, the wide range of differential diagnosis, the challenge of obtaining detailed history and difficulty of performing reliable physical examination in this age group. Management of underlying disorders can be medical, surgical or just observational.

What Are the Psychosocial Factors Associated With Migraine in the Child? Comorbid Psychiatric Disorders, Family Functioning, Parenting Style, or Mom's Psychiatric Symptoms?

OBJECTIVE

Psychiatric diagnoses, parenting style, family functioning among children and adolescents with migraine, and psychiatric symptoms of their mothers were examined.

METHODS

The K-SADS and other measurements were used to assess psychiatric disorders in 50 children with migraine (aged 8-18) and matched 50 controls.

RESULTS

At least one psychiatric disorder was diagnosed in 56% of the migraine group. The presence of any psychiatric disorder in children (odds ratio [OR] = 2.765, P = .027) and somatization symptoms in their mothers (OR = 2.061, P = .025) were increasing the risk of migraine diagnosis. The parenting style scale assessments revealed that parents in the migraine group grant their children less autonomy.

CONCLUSION

Psychiatric comorbidity, especially depression and anxiety disorders, is more common in children with migraine. The frequency of eating disorder is also higher. Evaluating comorbidity, family functioning, and particularly affective responsiveness in migraine families may guide the clinician to a targeted treatment plan.

Childhood trauma and lifetime syncope burden among older adults

OBJECTIVE

Vasovagal syncope is governed by the autonomic nervous system and often precipitated by highly salient emotional situations. We hypothesized that a lifetime tendency towards vasovagal syncope may be precipitated by exposure to childhood trauma.

METHODS

We examined data from the first wave of The Irish Longitudinal Study on Ageing (TILDA) of adults aged 50+ (n=6497) who were asked to report lifetime syncope frequency and any history of childhood sexual or physical abuse. Mediation analysis was used to assess the relative importance of pathways via which childhood trauma could plausibly increase risk of later life recurrent syncope including via depression, mid-life cardiovascular disease and frequent syncope in youth.

RESULTS

18.2% reported a lifetime syncopal event: 4.0% frequent syncope in youth and 1.5% recurrent syncope in the last year. 10.9% reported childhood sexual or physical abuse, rising to 14.2% among those reporting any lifetime syncopal event, 21.0% with frequent syncope in youth and 20.2% with recurrent syncope in later life. In fully adjusted logistic regression models the report of childhood sexual or physical abuse was independently associated with frequent syncope in youth (OR 1.85 (CI 95% 1.27-2.71); p=0.001; OR 2.14 (1.48-3.10); p<0.001 respectively). A history of frequent syncope in youth and depression partially mediated the relationship between childhood sexual and physical abuse and recurrent syncope in later life, while mid-life cardiovascular disease was less important.

CONCLUSION

Childhood trauma may contribute to a lifelong vasovagal tendency. Early attention should be given to the potential precipitating and perpetuating psychosocial factors affecting recurrent syncope.

Parenting stress and dimensions of parenting behavior: cross-sectional and longitudinal links with adolescents' somatization

OBJECTIVE

This study explored direct and indirect associations between adolescents' somatization, parenting stress, and three parenting dimensions (warmth, psychological control, and harsh punishment). First, the associations were explored cross-sectionally. Second, significant cross-sectional links were further examined longitudinally in order to decide upon temporality.

METHOD

A total of 1499 adolescents and one of their parents (mostly the mother) agreed to participate. Questionnaires were administered when the child was respectively 12-13 (T1), 13-14 (T2), and 14-15 (T3) years old. Adolescents reported on their somatization, parents on their parenting behavior and parenting stress.

RESULTS

Cross-sectionally, indirect links were found between all parenting dimensions and adolescents' somatization, through parenting stress. Longitudinal examination revealed two key aspects. First, parenting stress significantly predicted somatization. Higher T1 parenting stress was predictive for higher T2 and T3 somatization. When controlled for T1 parenting stress, higher T2 parenting stress (or in other words increased parenting stress at T2) was predictive for lower T3 somatization. Second, parenting stress was found to significantly predict parenting behaviors. Higher T1 parenting stress was predictive for higher T2 and T3 harsh punishment but increased parenting stress at T2 was predictive for lower harsh punishment one year later. Higher T1 parenting stress significantly predicted higher T2 psychological control.

CONCLUSIONS

Clinicians should be aware that parenting stress may be a risk factor for the development of somatization in early adolescence. However, in later adolescence, increased parenting stress might be protective.

Parental anxiety at initial acute presentation is not associated with prolonged symptoms following pediatric concussion

OBJECTIVES

Anxiety modulates symptom perception in adults following concussion, prolonging the time to full recovery. The authors sought to determine whether parental anxiety was associated with persistent postconcussive symptoms (PCS) in their children following concussion.

METHODS

A prospective observational cohort with 98 children aged 5 to 17 years following concussion participated from a tertiary pediatric emergency department (ED). The main exposure was parental anxiety at the time of acute presentation following pediatric concussion, measured using the self-administered, validated Spielberger State-Trait Anxiety Inventory-State Anxiety Scale (STAI-S). The primary outcome measured was presence of PCS in the child at 1 month, per the validated Post-Concussive Symptom Inventory (PCSI). Secondary outcome measures included parental anxiety score over time, school absenteeism, and return to sports. Data were collected during the initial ED visit and at 3-day, 7-day, 2-week, 1-month, and 3-month follow-ups.

RESULTS

Of 98 children enrolled, 27% (95% confidence interval [CI] = 19% to 36%) developed PCS at 1 month. No significant associations were detected between parental anxiety at the index visits and the number of previous pediatric concussions (p = 0.73), sex (p = 0.61), loss of consciousness (p = 0.43), history of migraines (p = 0.31), or history of anxiety diagnosed in the patients (p = 0.09). A significant association was noted between patient diagnosis of attention deficit hyperactivity disorder (ADHD) and parental anxiety at the index visits (p = 0.001). Parental anxiety at acute presentation was not associated with children's prolonged symptoms at 1 month (p = 0.63). Parental anxiety remained elevated in parents whose children had prolonged symptoms compared to those parents whose children's symptoms resolved (median = 30, interquartile range [IQR] = 22 to 44; and median = 21, IQR = 20 to 25, respectively; p < 0.001). Initial parental anxiety presentation was not associated with school absenteeism (p = 0.23) or not returning to sport or gym class (p = 0.89). There were no significant effects involving ADHD alone (p = 0.44) or together with baseline parental anxiety (p = 0.36 for ADHD and p = 0.55 for anxiety) using logistic regression analysis to examine potential predictive effects of child's ADHD combined with parental anxiety at the index visit on persistent symptoms at 1 month.

CONCLUSIONS

Parental anxiety at time of acute presentation does not appear to be associated with prolongation of postconcussive symptoms in their children. However, parents of persistently symptomatic children remain significantly more anxious than those whose children's symptoms have resolved. Future research should attempt to reduce the familial burden of concussion through expectation management strategies.

Vertigo in children and adolescents: characteristics and outcome

Objectives. To describe the characteristics and outcome of vertigo in a pediatric population. Patients. All children and adolescents presenting with vertigo to a tertiary otoneurology clinic between the years 2003–2010 were included in the study. Results. Thirty-seven patients with a mean age of 14 years were evaluated. The most common etiology was migraine-associated vertigo (MAV) followed by acute labyrinthitis/neuritis and psychogenic dizziness. Ten patients (27%) had pathological findings on the otoneurological examination. Abnormal findings were documented in sixteen of the twenty-three (70%) completed electronystagmography evaluations. Twenty patients (54%) were referred to treatment by other disciplines than otology/otoneurology. A follow-up questionnaire was filled by twenty six (70%) of the study participants. While all patients diagnosed with MAV had continuous symptoms, most other patients had complete resolution. Conclusions. Various etiologies of vertigo may present with similar symptoms and signs in the pediatric patient. Yet, variable clinical courses should be anticipated, depending on the specific etiology. This is the reason why treatment and follow up should be specifically tailored for each case according to the diagnosis. Close collaboration with other medical disciplines is often required to reach the correct diagnosis and treatment while avoiding unnecessary laboratory examinations.

Do parent protective responses mediate the relation between parent distress and child functional disability among children with chronic pain?

OBJECTIVES

To examine whether protective parent responses mediate the relation between parent distress and child functioning.

METHODS

At a pain clinic evaluation, 157 families participated. Parents completed measures of global distress (BSI-18), distress in the context of their child's pain (BAP-PIQ), and protective responses to their child's pain. Children completed measures of functional disability and pain.

RESULTS

BAP-PIQ subscales were significantly associated with child functional disability, whereas BSI subscales were unrelated. Protective parent responses partially mediated the relation between parent distress and child functional disability for depression, anxiety, and catastrophizing. However, parent protective behavior fully mediated the relationship between parent helplessness and child functional disability, indicating that feelings of parent helplessness did not uniquely contribute to child functional disability. Discussion Results suggest that when treating youth with chronic pain, parental distress in the context of children's pain needs to be addressed.

Child and family psychiatric and psychological factors associated with child physical health problems: results from the Boricua youth study

To examine associations among Puerto Rican children's physical health problems and children's internalizing disorders, parental psychopathology and acculturative stress, and family factors. A population-based probability sample of 2491 Puerto Rican children, aged between 5 and 13 years, and caregivers from the South Bronx and the U.S. Commonwealth of Puerto Rico participated in this study. The parent version of the Diagnostic Interview Schedule for Children-IV was used to assess children's internalizing disorders. Children's anxiety disorders, parental psychopathology, and acculturative stress were associated with childhood asthma, abdominal pain, and headaches. Children's depressive disorders, maternal acceptance, and family functioning were associated with abdominal pain and headaches. Parents of children living in Puerto Rico were more likely to report physical health problems in their children than in the Bronx. Children's internalizing disorders, parental psychopathology, and acculturative stress may be important areas to target among Puerto Rican children with physical health problems.

Somatoform disorders in vertiginous children and adolescents

OBJECTIVE

To investigate the frequency and characteristics of psychiatric co morbidity in a group of vertiginous children.

METHODS

A retrospective review of patient notes between years 2000 and 2006 in the ENT clinic of Helsinki University Hospital. Patients were identified from the clinic database, based on hospital discharge codes.

RESULTS

119 children were examined because of vertigo. Nine vertiginous children had purely psychogenic vertigo. The main psychiatric diagnosis was depression. The prevalence of somatoform disorders was 2.5%. According to our study the main predictors of a psychogenic vertigo were constant or frequent vertigo usually with coexisting headaches, absence from school and problems with relationships at school or home.

CONCLUSION

Somatisation should always be kept in mind while dealing with vertiginous children. A thorough clinical work-up is needed to rule out potential illnesses, but as soon as the possibility of somatisation comes to mind, psychiatric consultation is recommended.

[Therapy of tinnitus in children]

Tinnitus in childhood is quite common when children are directly asked about this syndrom. Children rarely spontaneously complain of tinnitus. Material consists of 67 children (6-18 year old) with tinnitus, treated in the Pediatric Otolaryngology Clinic and Outpatient. Between children there were 2 groups: I tinnitus connected with hearing loss--35 children, II tinnitus without hearing loss--32 children. Methods. Anamnesis, otolaryngologic, neurologic, psychologic examinations, panel of audiologic tests before and after treatment of betahistine. In 12 patients there were recognized conductive hearing loss and they were excluded from therapy of betahistine. 55 children were treated with betahistine (Betaserc). Results indicates that betahistine is a good drug in therapy of tinnitus in children.

Recurrent headache as the main symptom of acquired cerebral toxoplasmosis in nonhuman immunodeficiency virus-infected subjects with no lymphadenopathy: the parasite may be responsible for the neurogenic inflammation postulated as a cause of different types of headaches

Headache and/or migraine, a common problem in pediatrics and internal medicine, affect about 5% to 10% children and adolescents, and nearly 30% of middle-aged women. Headache is also one of the most common clinical manifestations of acquired Toxoplasma gondii infection of the central nervous system (CNS) in immunosuppressed subjects. We present 11 apparently nonhuman immunodeficiency virus-infected children aged 7 to 17 years (8 girls, 3 boys) and 1 adult woman with recurrent severe headaches in whom latent chronic CNS T. gondii infection not manifested by enlarged peripheral lymph nodes typical for toxoplasmosis, was found. In 7 patients, the mean serum IgG Toxoplasma antibodies concentration was 189 +/- 85 (SD) IU/mL (range 89 to 300 IU/mL), and in 5 other subjects, the indirect fluorescent antibody test titer ranged from 1:40 to 1:5120 IU/mL (n= <1:10 IU/mL). Some of the patients suffered also from atopic dermatitis (AD) and were exposed to cat and/or other pet allergens, associated with an increased IL-4 and decreased IFN-gamma production. These cytokine irregularities caused limited control of cerebral toxoplasmosis probably because IL-4 down-regulated both the production of IFN-gamma and its activity, and stimulated production of a low NO-producing population of monocytes, which allowed cysts rupture, increased parasite multiplication and finally reactivation of T. gondii infection. The immune studies performed in 4 subjects showed a decreased percentage of T lymphocytes, increased total number of lymphocytes B and serum IgM concentration, and impaired phagocytosis. In addition, few of them had also urinary tract diseases known to produce IL-6 that can mediate immunosuppressive functions, involving induction of the anti-inflammatory cytokine IL-10. These disturbances probably resulted from the host protective immune reactions associated with the chronic latent CNS T. gondii infection/inflammation. This is consistent with significantly lower enzyme indoleamine 2,3-dioxygenase (IDO) activity reported in atopic than in nonatopic individuals, and an important role that IDO and tryptophan degradation pathways plays in both, the host resistance to T. gondii infection and its reactivation. Analysis of literature information on the subjects with different types of headaches caused by foods, medications, and other substances, may suggest that their clinical symptoms and changes in laboratory data result at least in part from interference of these factors with dietary tryptophan biotransformation pathways. Several of these agents caused headache attacks through enhancing NO production via the conversion of arginine to citrulline and NO by the inducible nitric oxide synthase enzyme, which results in the high-output pathway of NO synthesis. This increased production of NO is, however, quickly down-regulated by NO itself because this biomolecule can directly inactivate NOS, may inhibit Ia expression on IFN-gamma-activated macrophages, which would limit antigen-presenting capability, and block T-cell proliferation, thus decreasing the antitoxoplasmatic activity. Moreover, NO inhibits IDO activity, thereby suppressing kynurenine formation, and at least one member of the kynurenine pathway, 3-hydroxyanthranilic acid, has been shown to inhibit NOS enzyme activity, the expression of NOS mRNA, and activation of the inflammatory transcription factor, nuclear factor-kB. In addition, the anti-inflammatory cytokines IL-4 and IL-10, TGF-beta, and a cytokine known as macrophage deactivating factor, have been shown to directly modulate NO production, sometimes expressing synergistic activity. On the other hand, IL-4 and TGF-beta can suppress IDO activity in some cells, for example human monocytes and fibroblasts, which is consistent with metabolic pathways controlled by IDO being a significant contributor to the proinflammatory system. Also, it seems that idiopathic intracranial hypertension, pseudotumor cerebri, and aseptic meningitis, induced by various factors, may result from their interference with IDO and inducible nitric oxide synthase activities, endogenous NO level, and cytokine irregularities which finally affect former T. gondii status 2mo in the brain. All these biochemical disturbances caused by the CNS T. gondii infection/inflammation may also be responsible for the relationship found between neurologic symptoms, such as headache, vertigo, and syncope observed in apparently immunocompetent children and adolescents, and physical and psychiatric symptoms in adulthood. We therefore believe that tests for T. gondii should be performed obligatorily in apparently immunocompetent patients with different types of headaches, even if they have no enlarged peripheral lymph nodes. This may help to avoid overlooking this treatable cause of the CNS disease, markedly reduce costs of hospitalization, diagnosis and treatment, and eventually prevent developing serious neurologic and psychiatric disorders.

Vertigo in childhood: a clinical experience

OBJECTIVE

Vertigo in childhood is a complaint consisting of a wide spectrum of diagnoses. The aim of this study was to evaluate pediatric patients with vertigo with normal eardrum and middle ear findings and discuss the differential diagnoses.

METHODS

Patient records of 50 children under 18 years of age with vertigo as the chief complaint, examined at the Baskent University, Research and Application Centers at Konya and Adana otorhinolaryngology clinics between May 2003 and October 2005 were retrospectively reviewed. The questionnaires, laboratory tests including blood samples, audiological and vestibular tests, and final diagnoses were analyzed. Patients with perforated eardrums, otitis media with effusion, and acute upper respiratory tract infections were not included in the study.

RESULTS

The study group consisted of 50 patients (33 females, 66%; 17 males, 34%), between 4 and 17 years of age (mean age, 11.5+/-3.9 years). Severe sensorineural hearing loss was present in one patient unilaterally (2%) and one patient bilaterally (2%). Bilateral low-frequency sensorineural hearing loss was present in one patient (2%). Electronystagmography revealed central vestibular abnormalities in three patients (6%). Canal paresis was established in six patients (12%). The Dix-Hallpike test was positive in six patients (12%). The most frequent cause of vertigo was migraine, occurring in 34% of patients (n=17). Other less-frequent etiologies of vertigo were benign paroxysmal vertigo (n=6; 12%), benign paroxysmal positional vertigo (n=6; 12%), psychogenic vertigo (n=5; 10%), epilepsy (n=3; 6%), metabolic disorders (n=3; 6%), vestibular neuritis (n=2; 4%), Meniere's disease (n=1; 2%), perilymphatic fistula (n=1; 2%), amblyopia (n=1; 2%), and unclassifiable (n=5; 10%).

CONCLUSIONS

Migraine was found to be the most frequent presenting diagnosis in childhood vertigo, although several peripheral vestibular disorders also were diagnosed. Evaluation of vertigo in childhood should begin with a thorough neuro-otologic evaluation and include other relevant multidisciplinary team members as needed to avoid unnecessary effort and cost.
