Diaschisis

Diaschisis

Diaschisis (from Greek, meaning "shocked throughout"[1]) is a sudden loss of function in a portion of the brain connected to but at a distance of a damaged area.[2] The site of the originally damaged area and of the diaschisis are connected to each other by neurons.[3] The loss of the damaged structure disrupts the function of the remaining intact systems and causes a physiological imbalance. The injury is produced by an acute focal disturbance in an area of the brain. Some function may be restored with gradual readjustment of the intact but suppressed areas.[citation needed]
The term diaschisis was coined by von Monakow in 1914. Currently the term diaschisis is used to describe a depression of regional neuronal metabolism and cerebral blood flow caused by dysfunction in an anatomically separate but functionally related neuronal region.[1]

It is important to note that diaschisis is a dysfunction of tissue that is not damaged but for which the blood supply has been altered because of interruption of "up stream". Diaschisis can be related to traumatic brain injury or stroke. The relief of diaschisis can sometimes be achieved through intervention and the brain's natural neuroplasticity.
