Vascular dementia was found to have either comparable or worse survival rates when compared to Alzheimer's disease; [22] another 2014 study found that the prognosis for people with vascular dementia was worse for male and older people. [23] Vascular dementia may be a direct cause of death due to the possibility of a fatal interruption in the ...
A study from the National Library of Medicine found forms of dementia that affect mental health and behavior — such as Lewy body dementia — may cause paranoia in earlier stages.
[25] [26] As of 2020, there were approximately 50 million people worldwide with Alzheimer's disease.

In extreme cases, individuals may completely forget who they are. Generally, this is a more severe type of amnesia known as global, or generalized amnesia. [12] However, memory loss can also be selective or categorical, manifested by a person's inability to remember events related to a specific incident or topic.
Again, dementia is a complex disease—and this is just one study. However, other studies have also found a link between having a lower level of education and a higher risk of developing dementia.
