Because of the hypoxic damage that occurs as a result of brain injury in epileptic patients, it often causes varying degrees of neuropsychological changes. The longer the history of epilepsy and the greater the number of seizures, the more severe and involved the neuropsychological effects. (1) Mental impairment. It is most common in patients with intractable epilepsy. The majority of patients are dull-witted, with severe cases reaching imbecility and foolishness, while a small number of patients have a moderate IQ and few are wise and demented. (2) Language disorders. The main manifestation is the decrease of verbal expression, verbal communication and verbal use ability. Patients have difficulty in describing things and expressing their feelings in rich language, and in severe cases, they may have difficulty in speaking, slurred pronunciation or mispronunciation. (3) Motor disorders. The chance of occurrence is low, and complete paralysis of the limbs (except in motor areas) rarely occurs. Only minor or mild motor dysfunction is reflected in prolonged fine and coordinated movements. (4) Attention and memory disorders. Patients show difficulty in concentration, show dullness, fixation, reduced interest while attention is frozen to something, difficulty in mastering new learning content, and poor academic performance. (5) Emotional and personality disorders. Patients have a simple way of thinking, reduced ability to think concretely and abstractly, and insufficient ability to associate and discriminate. It is difficult to control the emotion, easy to fluctuate significantly in the moment, strong excitement or tension, out can appear depression, anxiety, etc. (6) Cognitive impairment. If the lesion is located in the parieto-occipital lobe, visual-spatial agnosia, face cognitive impairment and color recognition difficulties may occur. Temporal lobe epilepsy may present with visual distortions, illusions and hallucinations. (7) Social adjustment disorder. Poor academic performance, difficulty in completing normal schooling, poor work skills and interpersonal tension, and difficulties in employment. There are obvious personality and psychiatric changes, and changes in sexual behavior, which cause many conflicts in the family, and are often the main problems that cause marriage breakup and family disintegration.
