Postoperative delirium is a common complication of deep brain stimulation in Parkinson's disease, which affects the short-term and long-term prognosis of Parkinson's disease patients.With the continuous development of deep brain stimulation for Parkinson's disease in China, the prevention and treatment of postoperative delirium has also received increasing attention. To promote standardization and normalization of the prevention and treatment of delirium after deep brain stimulation for Parkinson's disease, reduce the occurrence of delirium after deep brain stimulation for Parkinson's disease in China, and achieve better prognosis. The Functional Neurosurgery Group of the Neurosurgery Branch of the Chinese Medical Association, Functional Neurosurgery Group of Chinese Congress of Neurological Surgeons and Chinese Neuromodulation Society organized experts with experience in deep brain stimulation for Parkinson's disease to write this consensus. Based on a systematic review and summary of domestic and international literature and clinical evidence related to delirium following deep brain stimulation for Parkinson's disease, this expert consensus was developed. It discusses six aspects: epidemiology, pathogenesis, risk factors, diagnosis, treatment, and prevention, and forms 14 recommended suggestions, providing reference and guidance for clinical diagnosis, treatment, and prevention of delirium after deep brain stimulation surgery in Parkinson's disease.
