Seizures
In
a small number of people, antipsychotic medication can lead to seizures.
A seizure is a disturbances of brain function due to a sudden, abnormal,
excessive, and disorganized discharge of brain cells. When a patient
has a seizure, he or she manifests "abnormal motor, sensory
and psychic phenomena". For example, the patient may get severe
convulsions.
Use of antipsychotic medication can lower
a person´s threshold for seizures, i.e. they happen more easily.
The frequency of seizures is dose-related, with higher doses related
to greater risks.
In particular, treatment with the atypic
antipsychotic clozapine may lead to a greater risk of seizures.
Sometimes the doctor chooses to combine antipsychotics with anticonvulsant
medications to cope with, and control, the seizure problems.
