Benign focal seizures of adolescence

Benign focal seizures of adolescence (BFSA) is a rare, self-limited epilepsy syndrome that typically manifests during adolescence, generally between the ages of 10 and 18 years. It is characterized by infrequent focal (partial) seizures that may involve motor, sensory, or autonomic symptoms depending on the cortical region involved. The seizures are typically brief and may occasionally secondarily generalize to tonic-clonic seizures. Importantly, this condition is considered benign because affected individuals have normal neurological development, normal brain imaging (MRI), and a favorable long-term prognosis with spontaneous remission usually occurring within a few years of onset. The condition primarily affects the central nervous system. Electroencephalography (EEG) findings may show focal epileptiform discharges, but interictal EEGs can also be normal. Neurological examination and cognitive function remain intact. Because seizures are infrequent and the condition is self-limiting, treatment with antiepileptic drugs may not always be necessary. When treatment is initiated, standard antiepileptic medications are generally effective in controlling seizures. The decision to treat is typically individualized based on seizure frequency and impact on the patient's daily life. Long-term prognosis is excellent, with most patients achieving complete seizure freedom, often allowing discontinuation of medication if it was started.
