Generalized seizures are a type of seizure that affects both sides of the brain simultaneously. They can cause a variety of symptoms, including loss of consciousness, muscle stiffness, and convulsions. These seizures can occur without warning and may last from a few seconds to several minutes. There are different types of generalized seizures, such as tonic-clonic seizures and absence seizures. Tonic-clonic seizures involve intense muscle contractions and shaking, while absence seizures may cause brief lapses in awareness. Treatment often includes medications to help manage and reduce the frequency of these seizures.
