Epilepsy is one of the common diseases in life, and people with epilepsy will have certain mental changes. Epileptic personality change is one of the epileptic psychiatric disorder syndromes, which is a group of primary recurrent abnormal brain discharges. The incidence of personality changes in epileptic patients generally ranges from 12-20%. Patients with epileptic personality changes are “bipolar”, showing irritability, irritability, viciousness, cruelty, complaining, pickiness, stubbornness, suspicion, vindictiveness and narrow-mindedness on the one hand, and conformity, over-politeness, gentleness and obedience, bending over backwards to please and fight for justice on the other. So the same patient can be a tendency to dominate, and some patients have both extremes of characteristics, but at different times one characteristic is more prominent. Patients may have low self-esteem due to trivial matters, or they may be impulsive, commit crimes or even kill for insignificant reasons, which are extremely harmful to society and families and should be given sufficient attention.
