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.

Article Synopsis
- * Researchers evaluated AR dimensions in 74 patients, finding that 32.4% exhibited ARD, with a notable correlation between ARD severity and skeletal/connective tissue disorders.
- * The study concluded that isolated ARD is prevalent in this population, and regular cardiac monitoring is essential for improving long-term health outcomes, despite unclear risk factors and complications.

Chromosome 22q11.2 deletion syndrome (22q11DS) is characterized by congenital cardiac abnormalities, hypoplastic thymus, palatal abnormalities, and hypocalcemia, although other clinical features are frequent such as autoimmune and psychiatric disorders. One-third of the patients have psychotic disorders, frequently followed by developmental regression and long-term cognitive disturbances.

Article Synopsis
- The 22q11.2 deletion syndrome (22q11.2DS) is a genetic disorder linked to various health issues, including heart defects, developmental delays, and hearing impairments due to ear malformations.
- A case study describes a 38-year-old male with 22q11.2DS who experienced fluctuating hearing loss and vertigo similar to Ménière's disease over a decade.
- Medical tests revealed issues like abnormal ear structures and endolymphatic hydrops, suggesting that problems with fluid flow in the ear can lead to acute vertigo and hearing loss in individuals with 22q11.2DS.
