Bilateral frontal polymicrogyria

Bilateral frontal polymicrogyria (BFPP) is a rare brain malformation characterized by an excessive number of abnormally small folds (gyri) on the surface of both frontal lobes of the brain. This condition results from abnormal development of the cerebral cortex during fetal life, specifically a disruption in the later stages of cortical formation. The frontal lobes play a critical role in motor control, executive function, language, and social behavior, and their malformation leads to a range of neurological difficulties. The key clinical features of bilateral frontal polymicrogyria include intellectual disability of variable severity, spastic quadriparesis or diplegia (increased muscle stiffness affecting the limbs), epilepsy (seizures that may be difficult to control), speech and language delays, and cognitive impairment. Motor development is typically delayed, and affected individuals may have difficulty with fine motor coordination. Some patients also exhibit mild facial features associated with the condition. Seizure types can vary and may include generalized tonic-clonic, absence, or focal seizures, with onset typically in childhood. There is currently no cure for bilateral frontal polymicrogyria, and treatment is supportive and symptomatic. Management focuses on seizure control with antiepileptic medications, physical therapy and rehabilitation for motor difficulties, speech and language therapy, and educational support tailored to the individual's cognitive abilities. In cases of drug-resistant epilepsy, surgical evaluation may be considered. The prognosis varies depending on the severity of the cortical malformation and the degree of associated neurological impairment. Genetic counseling is recommended for affected families, as both genetic and non-genetic (such as prenatal infections or vascular events) causes have been implicated.
