[Case report of a boy with Prader-Willi syndrome and focal epilepsy]
Insights
This case report details an 11-year-old boy with Prader-Willi syndrome and partial epilepsy, highlighting extreme hypotonia and developmental delays. The study documents his significant physical, cognitive, and neurological characteristics, including obesity and abnormal EEG findings.
Area of Science:
- Genetics and Developmental Pediatrics
- Neurology and Clinical Neurophysiology
- Endocrinology and Metabolism
Background:
- Prader-Willi syndrome (PWS) is a complex genetic disorder characterized by hypotonia, developmental delays, and hyperphagia.
- Epilepsy is a recognized, though not universal, comorbidity in individuals with PWS.
- This report presents a unique case to further understand the PWS phenotype and its neurological manifestations.
Observation:
- An 11-year-old male with PWS presented with severe infantile hypotonia, delayed motor and speech milestones, and later onset of partial epilepsy.
- Clinical examination revealed characteristic PWS features including obesity, hypogonadism, minor dysmorphies, and skeletal anomalies.
- Neurological assessment showed abnormal electroencephalogram (EEG) findings with focal irritative discharges in the left hemisphere.
Findings:
- The patient exhibited significant developmental retardation, obesity, hypogonadism, and multiple minor morphological and skeletal anomalies.
- Dermatoglyphic analysis revealed unique characteristics, and glucose tolerance tests were abnormal.
- EEG demonstrated paroxysmal discharges indicative of partial epilepsy, primarily in the left frontal-temporal regions.
Implications:
- This case underscores the variable presentation of Prader-Willi syndrome and the importance of monitoring for neurological comorbidities like epilepsy.
- Understanding the specific phenotype, including EEG abnormalities, can aid in personalized management strategies for PWS patients.
- Further research into the neurobiological underpinnings of epilepsy in PWS may reveal targeted therapeutic approaches.
Abstract:
An 11-old boy with Prader-Willi syndrome and partial epilepsy was reported. Muscular hypotonia in early infancy was extreme and developmental milestones were retarded, especially walk and speech. He achieved these landmarks within three years. The first seizure disorder was seen in the 9th year. The patient was characterized by hypotonic musculature, severe mental retardation, obesity (gynaecomasty, excess of fat on the thighs, the abdomen and the trunk), hypogonadism (a minute penis, hypoplastic scrotum and cryptorchidism). Apart from these characteristics, the patient presented some minor morphological anomalies (turicephalic skull, high-arched palate, abnormally shaped pinnae, clinodactily, defects on teeth enamel), and some skeleton and joint anomalies (small feet, kyphosis, lumbar lordosis, knock-knee, flat foot). Speech retardation, behaviour disturbance and inappropriate emotional reaction were noted. Karyotype was normal. Dermatoglyphic analysis showed some significant qualitative and quantitative characteristics. An abnormal glucose tolerance curve was obtained. Electroencephalogram showed an irritative paroxysmal discharge with primary focal activity in frontal-temporal cortical regions of the brain left hemisphere.
