Delirium syndrome

Delirium syndrome (delirium syndrome) is a group of syndromes manifested by a wide range of cognitive disorders, especially the main feature of consciousness. It is often caused by diffuse brain, temporary poisoning infection or metabolic disorders. Because it often occurs in diseases such as acute onset, short duration, rapid development of toxic infections, and brain trauma, it is also called acute brain syndrome or acute confusional state. Delirium syndrome is the most common mental disorder in general hospitals, accounting for about 5% to 15% of internal and surgical patients, most of which can be recovered. The following six types of patients are more prone to delirium: ① elderly, ② children, ③ after heart surgery, ④ burns, ⑤ brain damage, ⑥ drug dependent people. Recently, two general hospitals abroad conducted epidemiological studies, and found that there were signs of delirium among the elderly aged 70 and over, which were 30% and 50%, respectively. However, since most elderly patients with physical disorders are accompanied by mild mental obsession and often stay at home for treatment, the incidence of delirium in the elderly appears to be much higher than generally estimated.
