The anticonvulsants are a diverse group of pharmaceuticals used in the treatment of epileptic seizures. Anticonvulsants are also increasingly being used in the treatment of bipolar disorder, since many seem to act as mood stabilizers. The goal of an anticonvulsant is to suppress the rapid and excessive firing of neurons that start a seizure. Because of this, anticonvulsants also have proven effective in treating many kinds of dysfunctional anxiety. Failing this, an effective anticonvulsant would prevent the spread of the seizure within the brain and offer protection against possible excitotoxic effects that may result in brain damage. However, anticonvulsants themselves have been linked to lowered IQ in children. Anticonvulsants are often called antiepileptic drugs (abbreviated \"AEDs\") or antiseizure drugs (abbreviated \"ASDs\").
