Abstract
Nodding syndrome (NS) is a debilitating yet often neglected neurological disease affecting thousands of children in several sub-Saharan African countries. The cause of NS remains unknown, and effective treatment options are lacking. Moreover, knowledge regarding NS is scarce and is based on a limited number of publications, with no comprehensive overview published to date. Therefore, the aim of this scoping review was to summarise the current evidence and identify existing knowledge gaps in order to help clinicians, scientists, and policymakers develop guidelines for prioritising this severe condition. We searched the Medline (Ovid), Embase (Ovid), Scopus, and Global Health Library databases in accordance with the PRISMA extension for scoping review guidance and in accordance with the Joanna Briggs Institute guidelines and methodology for a scoping review, using keywords describing NS. We then extracted and presented the original data regarding the epidemiology, aetiology, pathophysiology, clinical features, diagnosis, management, and outcomes of NS, as well as community perceptions and the psychosocial and economic impact of NS. Out of 1470 identified articles, a total of 69 were included in this scoping review. Major gaps exist in understanding the aetiology and pathogenesis of NS. Future research is urgently needed not only to address these gaps, but also to study the treatment options, epidemiology, and psychosocial and economic impacts of NS. Innovative interventions and rehabilitation programmes designed to address the psychosocial and economic burdens associated with NS are also urgently needed.

Abstract
Nodding syndrome is an enigmatic neuropsychiatric and epileptiform disorder associated with psychomotor, mental, and physical growth retardation. The disorder affects otherwise previously normal children aged 3-18 years, with a slight preponderance for the male child. Nodding syndrome has been described in rural regions of some low-income countries in sub-Saharan Africa including northern Uganda, South Sudan, and a mountainous region of southern Tanzania. The cause of the disorder has hitherto eluded scientists. Neuroimaging studies show involvement of the nervous system with associated severe cortical atrophy in the affected children. The affected communities have generated a number of perceived causes including some conspiracy theories related to intentional poisoning of water sources and foods, and causes related to fumes and chemicals from ammunitions used during civil wars in the affected regions. From biomedical perspectives, the treatment of the affected children is geared towards symptoms control and rehabilitation. There is evidence that seizures and behavioral problems including wandering and episodes of aggressions are controllable with anticonvulsants, especially sodium valproate and antipsychotics. No treatments have proven effective in reversing the course of the disorder, and cure remains a distant goal. Community members have used indigenous medicines, cleansing rituals, and prayer interventions, but have not perceived any reasonable improvements. A randomized controlled clinical trial is ongoing in northern Uganda to test the efficacy and effectiveness of doxycycline in the treatment of nodding syndrome. The hypothesis underlying the doxycycline trial underscores the role of antigenic mimicry: that antibodies generated against an antigen of a microorganism that resides inside the black fly-transmitted parasite, Onchocerca volvulus becomes directed against nervous tissue in the brain. This paper reviews some of the recent advances in researches on the etiologies, pathophysiology, and treatment of nodding syndrome.

Abstract
This paper presents a comparative study on conceptualizations of the poorly understood nodding syndrome (NS) in Uganda and Tanzania. NS has been constructed as a biomedical category to serve global health discourse as well as national contexts of managing the condition. The paper looks into the shifting meanings and conceptualizations of NS in the affected areas of Kitgum (UG) and Mahenge (TZ) district. The perceived universality of biomedical classifications is problematized as conflicting with the specific contexts of lucluc and kifafa cha kusinzia. Reconciliation proves to be challenging, poignantly evoking the cultural construction as such of any medical condition.

PLoS One 2016; 11:e0159549. [PMID: 27471850 PMCID: PMC4966934 DOI: 10.1371/journal.pone.0159549] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2015] [Accepted: 07/04/2016] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Nodding syndrome is a neurological disorder which had affected about 3000 children with over 170 deaths in northern Uganda by 2012. With limited data on health seeking, the study aimed to assess the health seeking behavior and associated factors among caretakers of children with nodding syndrome in Pader district. METHODS A mixed methods cross sectional study was conducted in July 2013 among 249 caretakers of children with nodding syndrome in three sub-counties of Pader. Respondents were consecutively interviewed using semi-structured questionnaires. Eleven key informants were additionally interviewed. We determined the associations of various factors with health care seeking and obtained adjusted odds ratios and 95% confidence intervals using logistic regression model. Quantitative data was analysed using Stata version 12 while qualitative data was analysed manually and quotes reported. RESULTS Most caretakers, 78.3% (195/249) sought care first from a health facility, 12.9% (32/249) visited traditional healers and 8.8% (22/249) self-medicated. Of those who sought care from a health facility, 50% sought care after a month. Factors associated with improved care seeking included: Time taken to reach care 1-3 hours; adjusted odds ratio = 6.4 (95% CI = 2.96-14.03), time spent in care above five years; adjusted odds ratio = 12.0 (95% CI: 1.24-117.73) and changed care seeking place; adjusted odds ratio = 17.2 (95% CI: 3.64-81.67). CONCLUSION/ RECOMMENDATION Caretakers sought care from multiple places. One in five caretakers still sought care outside a formal health facility. Many respondents who sought care first from health facilities went late, at least one month after symptoms onset. Factors associated with health seeking included distance, duration in treatment and not having changing care provider. There is need for massive sensitization of community to enhance prompt care seeking. More research is needed to elucidate the cause, thus finding the treatment for nodding syndrome, to prevent "wandering in hope".

Abstract
Background Nodding syndrome has increasingly become an issue of public health concern internationally. The etiology of the disorder is still unknown and there are yet no curative treatments. We explored perceptions about treatment practices and barriers to health seeking for nodding syndrome in Pader and Kitgum districts in northern Uganda in order to provide data necessary for informing policy on treatment adherence and rehabilitations. Methods We used focus group discussions and individual interviews to gain deep insights into help-seeking and treatment practices for nodding syndrome. Purposive sampling was used to identify information-rich participants that included village health teams, community members not directly affected with nodding syndrome, district leaders, healthcare professionals, and caregivers of children affected with nodding syndrome. We used qualitative content analysis to analyze data and presented findings under distinct categories and themes. Results Caregivers and communities sought care from multiple sources including biomedical facilities, traditional healers, traditional rituals from shrines, and spiritual healing. Nodding syndrome affected children reportedly have showed no enduring improvement with traditional medicines, traditional rituals, and prayers. A substantial minority of participants reported minimal improvements in symptoms of convulsions with use of western medicines. Challenges involved in health seeking included; (1) health system factors e.g. long distances to facilities, frequent unavailability of medicines, few healthcare providers, and long waiting times; (2) contextual and societal challenges e.g. lack of money for transport and medical bills, overburdening nature of the illness that does not allow time for other activities, and practical difficulties involved in transporting the physically deformed and mentally retarded children to the health facilities. Conclusions Help-seeking for nodding syndrome is pluralistic and include use of traditional and biomedical practices. Western medicines admittedly showed at least short term control on nodding syndrome symptoms, especially convulsions and led in a few cases to regain of functional abilities. However, multiple barriers hinder health seeking and interfere with adherence to biomedical treatments. Regarding cure, there are hitherto no treatments participants perceive cure nodding syndrome.

Abstract
PURPOSE To describe the neurophysiological and clinical features of Nodding Syndrome (NS) in South Sudan. METHODS The study was performed at the Epilepsy Service of "Usratuna" sited in Juba, South Sudan. The clinical history of each subject was collected along with an EEG tracing. RESULTS Twenty-one children (10 females) were diagnosed with NS. Fifteen (72%) children were classified as Probable NS and six (28%) as Confirmed NS. They ranged in age between 6 and 14 years, and age at seizure onset ranged from 5 to 12 years. All the subjects presented with intellectual disability which was mild in severity in 12 (57%) cases, moderate in seven (33%) cases and severe in two (10%) cases. Interictal EEG was abnormal in 20 subjects. In 18 (85%) subjects, the EEG showed 2-3.5 Hz spike-and-wave discharges often intermingled with sharp waves. Intermittent light stimulation was normal. In 12 (57%) children, interictal abnormalities were activated by hyperventilation. Ictal EEG was obtained in three patients. In all ictal EEGs head nodding episodes came in clusters during hyperventilation. None of the patients achieved good seizure control even if all of them received antiepileptic treatment (carbamazepine alone [43%] or in association with phenobarbitone or phenytoin). CONCLUSION This study confirms that NS is an encephalopathy and intellectual disabilities are partially independent of seizure frequency and EEG pathological activity. Based on interictal and ictal EEG patterns and on the experience of other researchers, valproic acid would seem to be the first-choice antiepileptic drug. NS in South Sudan presents with clinical and neurophysiological features which are similar to those described in northern Uganda and more severe than in Tanzania.

Abstract
BACKGROUND Nodding syndrome, an epidemic epileptic encephalopathy of unknown etiology, has affected an estimated 1834 children in Northern Uganda. Children are being treated symptomatically but inconsistently with antiepileptic drugs. DESIGN Ten semistructured interviews with caregivers of affected children and five focus group discussions with 23 relatives, teachers, and religious leaders were conducted to examine the experiences of affected families and communities in Kitgum and Pader districts. The researcher also did participant observation during MoH outreach clinics. Data collection was carried out from July to September 2012, and data were analyzed through inductive thematic analysis. RESULTS Nodding syndrome severely affects the children's ability to participate in daily life activities. Daily seizures and physical features such as salivating and stunting make them unable to pass as normal, and mood changes make it difficult for some to interact with others. Caregivers of children with nodding syndrome feel confined to their homes, and economic activities are reduced, which affects entire families, especially the education of healthy siblings. The familial clustering and the unknown etiology made many separate from the affected children when eating, sleeping, and having seizures because of a fear of transmission through saliva. Families struggle to provide care with minimal resources and have experienced a reduction in visitors since their children were affected by nodding syndrome. There were signs of apathy in patterns of care, and, generally, parents felt that antiepileptic medicine had brought only slight improvement in their child's condition because many had begun treatment when developmental milestones had already been lost. CONCLUSIONS A consistent supply of antiepileptic medication is likely to reduce the stigma and fear of transmission, as the affected children's acceptance among others was greatly compromised whenever they had seizures. The loss and suffering involved with nodding syndrome are seen as a continuation of the confinement and trauma once caused by war, and a good regimen of medication is not the whole answer.

Abstract
Background Nodding syndrome, a disabling epidemic epileptic encephalopathy, has affected an estimated 1,834 children in northern Uganda, with reports of as many as 3,000. Etiology is unknown and children are being treated symptomatically but inconsistently with anti-epileptic drugs. Design This qualitative study comprised 10 semi-structured interviews with caregivers of affected children and five focus group discussions with 23 participants; relatives, teachers, and religious leaders. Data collection and participant observation were carried out from July to September 2012 in Kitgum and Pader districts. The material was coded through inductive thematic analysis. Results Nodding syndrome has brought signs of discrimination in school admission procedures, founded in a fear of transmission. The suffering and loss caused by nodding syndrome is collective, and participants felt that nodding syndrome was viewed as a threat to the Acholi only, and that interventions had therefore been delayed. Multiple theories of causation exist, most commonly that the disease is caused by chemicals from bombs or that food aid distributed in IDP camps had expired or been poisoned. A feeling of uncertainty was present in all focus group discussions, fueled by the fact that results of investigations were not being shared with the communities. It was especially agonizing that CDC results had been given to the Ugandan government in 2010 but not to the public. The definitive fear is that the disease will be the end of the Acholi. Conclusions This study provided insight into the perceptions of communities affected by an unknown emerging disease. Families of affected children are grieving not only their child's illness; it is a loss of social value and of lineage. The loss and suffering involved with nodding syndrome should be seen in the context of the wider suffering of a society disrupted by violent conflict. The memory of war is omnipresent and is also how nodding syndrome is understood.

Abstract
SUMMARY Epilepsy is a common neurological disease in tropical countries, particularly in sub-Saharan Africa. Previous work on epilepsy in sub-Saharan Africa has shown that many cases are severe, partly a result of some specific causes, that it carries a stigma, and that it is not adequately treated in many cases. Many studies on the epidemiology, aetiology, and management of epilepsy in sub-Saharan Africa have been reported in the past 10 years. The prevalence estimated from door-to-door studies is almost double that in Asia, Europe, and North America. The most commonly implicated risk factors are birth trauma, CNS infections, and traumatic brain injury. About 60% of patients with epilepsy receive no antiepileptic treatment, largely for economic and social reasons. Further epidemiological studies should be a priority to improve understanding of possible risk factors and thereby the prevention of epilepsy in Africa, and action should be taken to improve access to treatment.

Abstract
OBJECTIVE To explore processes of conceptualizing nodding syndrome (NS), an unknown illness which has been reported to affect thousands of children in post-conflict northern Uganda, in South Sudan and in Tanzania. DESIGN This qualitative study comprised 40 in-depth interviews with affected families, health workers and politicians during five months of fieldwork in northern Uganda and a review of available reports, newspapers and academic literature on NS. In addition, observations have been made at treatment centers and during outreaches and meetings. Focus is put on how meanings of key terms related to NS are produced and negotiated. Attention is being paid to the circulation of different discourses and explanatory models. RESULTS Discourses and explanatory models play an active role in the conceptualization of illness, as much by medical personnel as by affected families and the media. The prominent use of biomedical terms in the academic discourse on NS is striking; links are suggested with onchocerciasis and epilepsy. In contrast, the local discourse associates NS with social issues. The illness experiences are connected to the trauma of past conflict, to poverty and to (region-bound) frustration over neglect. The cultural significance of physical symptoms raises the question of the impact of culture on health. CONCLUSION By only looking at the biomedical significance of this new syndrome, we will miss important aspects of how this illness is being experienced and understood. In our future dealings with NS, we will have to consider and re-conceive the relation between culture and neurobiology.
