Focal impaired awareness seizures, previously known as complex partial seizures, occur when abnormal electrical activity in the brain affects a specific area, leading to a change in awareness or consciousness. During these seizures, individuals may appear awake but are not fully aware of their surroundings and may not respond to others. Symptoms can include confusion, repetitive movements, or unusual behaviors. These seizures can last from 30 seconds to a couple of minutes and may be followed by a period of confusion or fatigue. Treatment often involves medications, and understanding triggers can help manage the condition effectively.
