A 59-year-old woman was admitted to our psychiatric department for ECT.
She had been diagnosed with schizophrenia at the age of 17 years and had taken antipsychotic drugs for 42 years.
She had no history of alcohol consumption, drug use, or epileptic seizures.

One day, at the age of 55 years, she lay on a road and was unable to move or speak due to a catatonic state. However, medicines proved ineffective, despite attempting several types of second-generation antipsychotic drugs and benzodiazepines.She exhibited severe catatonia as well as many other psychotic symptoms, such as hallucination, delusion, and negative symptoms.She was taking risperidone 9 mg daily without side effects for nearly 10 years.These studies have indicated a dysfunction of the ANS in patients with schizophrenia [1, 2, 5–8].Measurement of salivary alpha-amylase  activity levels is reportedly useful for evaluating activity of the ANS [10–13], and a simple, noninvasive appliance has been recently developed to measure s AA activity levels [14, 15].Several studies have suggested that measuring salivary alpha-amylase activity levels is useful for evaluating the ANS activity and that s AA levels increase in schizophrenia and correlate with Brief Psychiatric Rating Scale (BPRS) scores.However, no study has examined the relationship between s AA activity levels and symptoms of schizophrenia with catatonic state. We present the case of a 59-year-old female with persistent catatonic schizophrenia treated by electroconvulsive therapy.In order to eliminate the effects of hospitalization, we measured s AA activity levels again not only immediately after hospitalization but also just before ECT.Thus, we measured her s AA activity levels twice before ECT.The pathology of schizophrenia remains unknown, and a relevant biomarker remains to be identified.Various studies have been conducted to address this, including studies on the autonomic nervous system (ANS) [1–7].
