The pathological superfluous pathogenesis lies in the alteration of the patient’s brain function, mostly because the patient’s thinking activity is too slow or stagnant, meandering, associating too many branches, doing unnecessary overly detailed and cumbersome descriptions, unable to make him speak a little more concise, must be finished in the way he originally spoke, this situation generally occurs in patients with epilepsy and mental retardation. The cause: 1. Epilepsy: is a sudden, episodic transient brain disorder caused by abnormal hyper-synchronous discharges in groups of brain cells. Two-thirds of the population with epileptic seizures have only one lifetime seizure, and the other one-third have recurrent seizures called epilepsy. Each seizure occurs as a painful seizure. Patients have a variety of seizure forms, sequelae and complications also show diversity, so it can be called a prominent representative of the diversity of neuropsychiatric disorder performance among organic diseases, a typical class of neuropsychiatric diseases, even its neurological seizures and psychiatric seizures occupy half. 2, mental retardation: also known as mental retardation, is a syndrome caused by a variety of causes of brain development disorders, with mental retardation and social adaptation difficulties as the main features, can be accompanied by some kind of mental or physical disease. It starts during the developmental period and progresses slightly with age, but moderate and severe cases still pose a heavy burden to the family and society. Mild patients have no obvious physical developmental abnormalities and are often overlooked in the recruitment experience and selected, causing difficulties in training and management of the troops, and should be taken into account.
