Ugo Cerletti (26 September 1877 – 25 July 1963) was an Italian neurologist who discovered the method of electroconvulsive therapy used in psychiatry. Electroconvulsive therapy is a therapy in which electric current is used to provoke a seizure for a short durration. This therapy is used in an attempt to treat certain mental disorders, and may be useful when other possible treatments have not, or cannot, cure the person of their mental disorder.
Ugo Cerletti was born in Conegliano, in the region of Veneto, Italy, on 26 September 1877. He studied Medicine at Rome and Turin, later specializing in neurology and neuropsychiatry. In his early scientific studies, Cerletti mainly focused on common issues in the fields of histology and histopathology. He demonstrated how the nervous tissue reacts to different pathogenic stimuli in its own ways, making the histopathology of nervous tissue an independent category in the study of medicine. As a student, he conducted some research under several influential people studying in the Medicinal field at that time. He studied with the most eminent neurologists of his time, first in Paris, France, with Pierre Marie and Dupré, then in Munich, Germany, with Emil Kraepelin (the "father" of modern scientific psychiatry) and Alois Alzheimer (the discoverer of the most common form of senile dementia, which today bears his name); and in Heidelberg, with Franz Nissl, a neuropathologist. Other large names in medicine that he studied with at the time include Sciamanna and Nissl.
