Poststroke Amnesia

Studies investigating the time course of poststroke memory function are scarce specially because the stroke does normally not affect structures involved in memory [1]. However, amnesia has been repeatedly reported in patients following surgical repair of anterior communicating artery (ACoA) aneurysms [2]. Cerebral aneurysm is a relatively common disease with a prevalence of 5% in Western populations and whose incidence of rupture is estimated at 10-15 per 10,000 inhabitants per year [3]. The survival to surgical repair of cerebral aneurysms has, fortunately, increased considerably nowadays. However, it is common to find some type of behavioural and cognitive impairments because of these accidents.
