Gestalt syndrome is also known as bed catching and gestalt sign. Groping is most often seen in delirium with severe illness, such as typhoid, typhus, epidemic B encephalitis, severe pneumonia, hepatic coma and other toxemia, alcohol intoxication, and after overdose of sedatives and atropine intoxication. When the patient sees aimless groping movements of the upper limbs, it is accompanied by mild impairment of consciousness, loss of orientation, irritability, babbling, and disorganized speech, which is called groping symptom. What are the causes of groping disorder? Generally speaking, this symptom is a sign of critical illness, indicating the inhibition of the cerebral cortex and subcortical reticular system. Delirium syndrome is a group of syndromes manifesting as widespread cognitive deficits, particularly impairment of consciousness. It is often caused by diffuse, temporary toxic brain infections or metabolic disturbances. It is also called acute encephalopathy syndrome or acute confusion state because it often occurs in acute onset, short duration and rapid development of lesions such as toxic infection and traumatic brain injury. Delirium syndrome is the most common type of mental disorder in general hospitals, accounting for about 5% to 15% of medical and surgical patients, and most can recover. The following six categories of patients are more prone to delirium: (1) elderly, (2) children, (3) post-heart surgery, (4) burn injuries, (5) brain damage, and (6) drug-dependent patients. In a recent epidemiological study conducted in two foreign general hospitals, it was found that 30% and 50% of the elderly aged 70 years and above showed signs of delirium, respectively. However, since most elderly patients with physical illnesses accompanied by mild mental confusion often stay at home for treatment, the incidence of delirium in the elderly seems to be much higher than generally estimated.
