An autopsy of [[stroke]] may be able to establish the time taken from the onset of cerebral infarction to the time of death.

Various microscopic findings are present at times from infarction as follows:<ref name="pmid19690757">{{cite journal|last1=Mărgăritescu |first1=O|last2=Mogoantă |first2=L|last3=Pirici |first3=I|last4=Pirici |first4=D|last5=Cernea |first5=D|last6=Mărgăritescu |first6=C| title=Histopathological changes in acute ischemic stroke. | journal=Rom J Morphol Embryol | year= 2009 | volume= 50 | issue= 3 | pages= 327–39 | pmid=19690757 | doi= | pmc= | url=https://www.researchgate.net/publication/26751521}}</ref>
