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. ==References== <references/> *Chang, Steven; Doty, James; Skirboll, Stephen; Steinberg, Gary.
