Neuropsychiatric disturbances caused by arsenic poisoning in 28 patients were reported. The incidence was 32.2% of all the arsenic poisoning patients. The patients were classified into three types according to their clinical symptoms. The neurologic type constituted 46.4%, mental type 21.4% and mixed type 32.1% of the patient respectively. Various abnormalities were found in EEG, EMG, EP and EKG examination. EMG and EP were still abnormal in most of the patients after treatment for three months. The results showed that arsenic poisoning may cause neuropsychiatric disturbances. The symptoms in these patients are serious and the recovery is quite slow.
