'''Brain ischemia''' (or '''cerebral ischemia''') is an [[ischemic]] condition where the [[brain]] or parts of the brain do not receive enough [[blood flow]] to maintain normal [[neurological]] function.
==Causes==
Cerebral ischemia can be the result of various [[diseases]], or the result of [[arterial]] obstruction such as [[strangulation]].
==Presentation==
Similarly to [[cerebral hypoxia]], severe or prolonged cerebral ischemia will result in [[unconsciousness]], [[brain damage]] or [[death]], mediated by the [[ischemic cascade]].
An extensive review of mechanisms by which ischemia damages the nervous system has been published by Peter Lipton.<ref name="urlIschemic Cell Death in Brain Neurons -- Lipton 79 (4): 1431 -- Physiological Reviews">{{cite web |url=http://physrev.physiology.org/cgi/content/full/79/4/1431 |title=Ischemic Cell Death in Brain Neurons -- Lipton 79 (4): 1431 -- Physiological Reviews |format= |work= |accessdate=}}</ref>
==Related conditions==
A related condition is [[subcortical ischemic depression]], also known as [[vascular depression]]. This condition is most commonly seen in elderly depressed patients. Late onset depression is increasingly seen as a distinct variety of depression, and is commonly detected with an MRI.
