Final answer:
Anticonvulsants, such as diazepam, are commonly used in the treatment of GTC seizures, and they help in improving prognosis and reducing brain damage. For absence epilepsy, different medications, particularly suited for managing the unique nature of these seizures, are employed.
Step-by-step explanation:
In the treatment of Generalized Tonic-Clonic (GTC) seizures, anticonvulsants like diazepam are often used. Diazepam is effective for managing active seizures and can improve long-term prognosis while reducing the risk of brain damage. It is important to note that diazepam is not usually self-administered, but given to patients who are actively seizing.
For the treatment of absence epilepsy, other types of medications may be used. These medications are geared towards stopping the brief, sudden lapses of consciousness characteristic of absence seizures. As always, treatment should be guided by a healthcare professional specialized in epilepsy management to ensure the best outcome for the patient.
