Vascular Dementia
Affecting 150,000 people in the UK, it is caused by reduced blood flow to the brain, which occurs because of stroke, or the hardening and narrowing of arteries (atherosclerosis). Vascular dementia is most prevalent in smokers or those with high blood pressure, Type 2 diabetes, obesity or heart problems. Symptoms include confusion, memory loss, slow thought patterns, impaired concentration, hallucinations, mood swings, depression and anxiety.
