Аннотация
BACKGROUND: The 22q11.2 deletion syndrome affects multiple organ systems, and the neurological manifestations are an important aspect of this disorder. Many are aware of cardiac anomalies associated with this uncommon genetic disorder. However, the different types of seizures, electroencephalography (EEG), and brain magnetic resonance imaging (MRI) findings seen in this condition are not appreciated.
METHODS: Medical records of four patients with epilepsy due to 22q11.2 deletion syndrome were retrospectively reviewed for documentation of seizure types, EEG, and brain MRI findings. In addition, we also did a literature review of previously reported individuals with unprovoked seizures in this condition.
RESULTS: A review of all published cases including our patients reveals that focal epilepsy (39 of 88, 44%) is the most common type followed by genetic generalized epilepsy (24 of 88, 27%). Diffuse cerebral atrophy and polymicrogyria were the most frequent MRI findings.
CONCLUSIONS: Patients with structural brain abnormalities, especially polymicrogyria and associated epilepsy should have a chromosomal microarray (CMA) performed to screen for the 22q11.2 deletion syndrome. Focal epilepsy and genetic generalized epilepsy are the most frequent epilepsy types reported in this condition.
