Diaschisis
Diaschisis (pronounced: /daɪˈæskɪsɪs/) is a medical term used to describe a sudden change or loss of function in a portion of the brain connected to a damaged area. The term is derived from the Greek word διάσχισις, meaning 'to cleave or split'.
Etymology
The term 'Diaschisis' was first introduced by the German neurologist and psychiatrist Carl Wernicke in 1894. It is derived from the Greek word διάσχισις (diaschisis), which means 'to cleave or split'. This term was used to describe the observed phenomenon where damage to one area of the brain can lead to functional deficits in a distant, structurally intact area.
