Diaschisis

Diaschisis (from the Greek “splitting, division” synonym - Monakov phenomenon) is a neurological phenomenon in which damage in one area of ​​the brain leads to dysfunction in distant but related areas.

With diaschisis, the activity of neurons in intact areas of the brain, remote from the site of damage, is suppressed. This is due to a disruption in the conduction of nerve impulses from the damaged area to the intact ones. As a result, metabolism and blood flow are reduced in intact areas.

The phenomenon of diaschisis was first described by the Russian neurologist A.V. Monakov in 1947. He observed this phenomenon in stroke patients, where a lesion in the frontal lobe caused a decrease in function in the opposite parts of the brain.

Diaschisis is usually reversible and goes away as the damaged nerve tracts are restored. However, in some cases it can persist for a long time and lead to permanent neurological impairment. Studying the mechanisms of diaschisis is important for understanding the processes of plasticity and recovery of the brain after damage.

Diaschisis is a disorder of brain development in which it is divided into separate areas located at a distance from each other. Diaschisis is diagnosed in people with physical and mental disorders, as well as in patients who have undergone brain surgery or treatment for a stroke. According to research, diaschisis can lead to dysfunction of the central nervous system (CNS), including impairment of motor skills, speech, thinking, memory and emotions. In this article we will look at the causes, symptoms and treatment of diaschisis.
