G40-G47: Episodic and paroxysmal disorders
G40: Epilepsy
Epilepsy, categorized under the ICD-10 code G40, encompasses a group of neurological disorders characterized by frequent seizures. These conditions can be caused by various factors including brain injury, stroke, tumors, infectious diseases that affect the brain, and genetic influences. Epilepsy manifests itself predominantly through repeated episodes of seizures that vary in frequency and severity, depending on the condition's specific subtype. Seizures often involve uncontrolled shaking and temporary confusion, but can also manifest in the form of brief stares or periods of unconsciousness. The progression of epilepsy varies largely between individuals and the specific type of condition. Generally, the primary system affected by epilepsy is the central nervous system, which comprises the brain and spinal cord. As the disease progresses, it may lead to problems in mental health, learning, memory, and overall neurological function.
