Status epilepticus is a medical emergency characterized by prolonged or continuous seizure activity without recovery between seizures. It can be convulsive, involving muscle contractions and loss of consciousness, or nonconvulsive with episodes of staring and unresponsiveness. Immediate treatment is needed to prevent permanent brain or heart damage. Diagnosis involves assessing symptoms, medical history, and tests like bloodwork, EEG, or brain imaging. Treatment focuses on stopping seizures and managing complications through medications, injury prevention, and educating patients and their families on self-care and coping strategies.
