Memory allows us to classify, store and retrieve information

Problems with memory are very common after stroke, and memory deficits are often revealed on formal testing. 

"Memory problems can lead to longer hospital stays, poorer functional outcomes, risks to personal safety, and can cause subjective distress to patients and their families. Memory loss is a characteristic feature of dementia, which affects about 20% of people 6 months after stroke."
