A Review on Focal Epilepsy: Clinical Features, Diagnostic Challenges, and Treatment Approaches.

Abstract Focal epilepsy, the most common type of epilepsy in adults, is distinguished by seizures that originate in a single area of one hemisphere of the brain. This study examines the clinical characteristics, underlying causes, and therapeutic options for focal epilepsy. The syndrome causes a variety of seizure forms, including focal aware seizures, focal seizures with decreased awareness, and subsequent generalized seizures. The aetiology is frequently complex, with structural brain abnormalities such as cortical malformations, traumatic traumas, infections, and vascular lesions being discovered. Despite breakthroughs in neuroimaging, a considerable minority of patients continue to be idiopathic. Anti-seizure drugs are the primary form of management, while surgical options are considered in pharmacoresistant patients. This review emphasizes the importance of understanding the complexities of focal epilepsy. Keywords: - Focal Epilepsy, Focal Seizure, EEG, ILAE.
