Summary
Fragile X syndrome, a common cause of intellectual disability, can present with epilepsy. Specific EEG patterns and seizures were observed only in males, suggesting a potential structural alteration.
Area of Science:
- Neurogenetics
- Epileptology
- Developmental Neuroscience
Context:
- Fragile X syndrome (FXS) is the leading genetic cause of intellectual disability.
- Epilepsy affects 20-40% of FXS patients, often considered a minor symptom.
- Specific age- and sex-dependent EEG patterns resembling rolandic epilepsy have been noted.
Purpose:
- To analyze clinical and electroencephalographic (EEG) manifestations in Fragile X syndrome patients.
- To investigate the relationship between EEG patterns, seizures, and sex in FXS.
- To identify potential differential diagnostic traits for FXS-associated epilepsy.
Summary:
- This study examined 10 patients (4-60 years old) with Fragile X syndrome.
- Three patients experienced partial seizures evolving into generalized seizures; two asymptomatic patients showed abnormal EEG findings.
- Abnormal EEG patterns and epileptic seizures were exclusively observed in male patients, with slow background activity noted in others.
- The presence of sharp waves preceding rolandic paroxysms may indicate a structural alteration in FXS.
Impact:
- Highlights the sex-specific presentation of epilepsy in Fragile X syndrome.
- Suggests that specific EEG findings, like sharp waves preceding rolandic paroxysms, could be a marker for underlying structural changes.
- Informs clinical evaluation and management of epilepsy in individuals with Fragile X syndrome.
