Sergei Sergeyevich Korsakov (Russian: Серге́й Серге́евич Ко́рсаков; 22 January 1854, Gus-Khrustalny – 1 May 1900, Moscow) was a neuropsychiatrist from the Russian Empire, known for his studies on alcoholic psychosis. His name is lent to the eponymous Korsakov's syndrome and Wernicke–Korsakoff syndrome.

Career

In 1892, Korsakov was appointed professor extraordinarius at a new university psychiatric clinic. During this time, he visited Vienna, where he was a pupil of Theodor Meynert. He was ordinarius of neurology and psychiatry from 1899 until his death the next year. He died from heart failure at the age of 46.^[1]

Legacy

Korsakov was one of the greatest neuropsychiatrists of the 19th century and published numerous works in neuropathology, psychiatry, and forensic medicine. Apart from his studies on alcoholic psychosis, he introduced the concept of paranoia and wrote an excellent textbook on psychiatry published in 1893. Additionally, he was a proponent of the non-restraint treatment in psychiatry.^[2] Korsakov studied the effects of alcoholism on the nervous system and drew attention to several cases of alcoholic polyneuropathy with distinctive mental symptoms (Korsakov's syndrome).^[3]

An able organiser, Korsakov was instrumental in founding the Moscow Society of Neuropathologists and Psychiatrists. The Zhurnal nevropatologii i psikhiatrii imeni Korsakova (Russian: Журнал невропатологии и психиатрии имени Корсакова, Korsakov Journal of Neurology and Psychiatry) was named after him.

According to a study conducted in 2015, Korsakov was included in "Russia team on medicine". This list includes fifty-three famous Russian medical scientists from the Russian Federation, the Soviet Union, and the Russian Empire who were born in 1757—1950.
