Schizophrenic disorders may have a relationship with epilepsy, particularly with temporal lobe epilepsy. In epileptic schizophrenia, catatonia is less common.
In epileptics, abnormal behaviour may occur during –
1. The actual fit (ictal) – During this stage, there is usually spontaneous and stereotype activity. The phase is short-lived and the activities have no relationship with the circumstance. The acts and behaviour are aimless and purposeless.
2. Post epileptic – The post epileptic abnormal activities are due to a state of mental confusion and are simple in nature. These may occur due to certain stimuli or may be performed on the basis of past experience and may be repetitive in nature. The subject is restless, aggressive, or fugue. The acts are automatic in nature. The person walks, fumbles or performs routine works blindly. He resists help or interference. Any purpose of any act is immediate and crude. This phase also stays for a short period.
3. In case of status epilepticus – The abnormal activities may last for a few hours.
Prolonged, elaborate, intelligent and purposeful acts may be seen in many varieties of mental unsoundness but not in case of epilepsy.
