Many studies have been conducted to determine average survival of patients with dementia. The studies were frequently small and limited, which caused contradictory results in the connection of mortality to the type of dementia and the patient's gender. A very large study conducted in Netherlands in 2015 found that the one-year mortality was three to four times higher in patients after their first referral to a day clinic for dementia, when compared to the general population. If the patient was hospitalized for dementia, the mortality was even higher than in patients hospitalized for cardiovascular disease.<unk>  was found to have either comparable or worse survival rates when compared to Alzheimer's Disease; another very large 2014 Swedish study found that the prognosis for<unk>  patients was worse for male and older patients. Unlike Alzheimer's disease, which weakens the patient, causing them to succumb to bacterial infections like pneumonia,<unk>  can be a direct cause of death due to the possibility of a fatal interruption in the brain's blood supply.
