Vascular dementia accounts for at least 20% of dementia cases, making it the second most common type.<ref name=pmid24267647>{{cite journal | vauthors = Iadecola C | title = The pathobiology of vascular dementia | journal = Neuron | volume = 80 | issue = 4 | pages = 844–866 | date = November 2013 | pmid = 24267647 | pmc = 3842016 | doi = 10.1016/j.neuron.2013.10.008 }}</ref> It is caused by disease or injury affecting the [[cerebral circulation|blood supply to the brain]], typically involving a series of [[mini-stroke]]s. The symptoms of this dementia depend on where in the brain the strokes occurred and whether the blood vessels affected were large or small.<ref name="Memory Loss"/> Repeated injury can cause progressive dementia over time, while a single injury located in an area critical for cognition such as the hippocampus, or thalamus, can lead to sudden cognitive decline.<ref name=pmid24267647 /> Elements of vascular dementia may be present in all other forms of dementia.<ref name=Baskys>{{cite journal |vauthors=Baskys A, Cheng JX |title=Pharmacological prevention and treatment of vascular dementia: approaches and perspectives |journal=Exp Gerontol |volume=47 |issue=11 |pages=887–891 |date=November 2012 |pmid=22796225 |doi=10.1016/j.exger.2012.07.002 |s2cid=1153876}}</ref>

[[Neuroimaging|Brain scans]] may show evidence of multiple strokes of different sizes in various locations. People with vascular dementia tend to have risk factors for [[vascular disease|disease of the blood vessels]], such as [[tobacco use]], [[high blood pressure]], [[atrial fibrillation]], [[Hypercholesterolemia|high cholesterol]], [[diabetes]], or other signs of vascular disease such as a previous heart attack or [[angina]].<ref>{{Cite web|title=Vascular dementia – Symptoms and causes|url=https://www.mayoclinic.org/diseases-conditions/vascular-dementia/symptoms-causes/syc-20378793|access-date=July 8, 2021|website=Mayo Clinic|language=en}}</ref>
