A structured guide for understanding the disease and preparing for clinical conversations.
Polymicrogyria is a brain development disorder in which an abnormally large number of small gyri are formed in the cerebral cortex.
Representative clinical manifestations include epileptic seizures, developmental delay, difficulties with muscle strength or motor control, and language or learning problems.
Causes are diverse and may involve genetic changes related to brain development, infections during pregnancy, or issues with blood flow or oxygen supply.
Abnormalities in the process of forming the structure and neural connections of the cerebral cortex can cause seizures and affect motor, language, or cognitive functions.
Symptoms and functional levels vary greatly depending on the location and extent of the lesion, whether there is unilateral or bilateral cerebral involvement, and accompanying genetic or brain development factors.
Symptoms can appear at various stages from infancy to adulthood, and the course of seizures and developmental/functional problems also differs from person to person.
Diagnosis is based on medical history, developmental assessment, and neurological examination, with brain MRI being central, and EEG and genetic testing considered as needed.
Since the degree of symptoms or future prognosis cannot be determined solely by the structural abnormalities seen on MRI, imaging results must be interpreted along with clinical evaluation.
Management focuses on seizure control and supporting developmental, motor, and language functions, with collaboration from neurology, rehabilitation medicine, pediatric development, etc., if necessary.
Treatment focuses on reducing seizures and functional difficulties and helping participation in daily life, rather than reversing already formed brain structures.
Follow-up observations check seizure frequency, treatment response, and changes in development and function, and being enrolled in a clinical trial does not, by itself, imply effectiveness or that it is standard treatment.
In clinical practice, it is important to simultaneously assess seizure type and changes, developmental, learning, and motor functions, sleep and behavioral problems, and family goals and necessary support.
