Vascular dementia (VaD) is caused by reduced blood supply to the brain due to diseased blood vessels. How VaD affects people varies depending on the underlying causes and generally from person to person. Symptoms may develop suddenly, for example after a stroke, or more gradually, such as with a small vessel disease. Risk factors for VaD include smoking, diabetes, hypertension, raised cholesterol and obesity. People with VaD may: 

  • Have problems with planning or organising, making decisions or solving problems 
  • Experience difficulties following a series of instructions 
  • Appear to have slower speed of thought 
  • Have problems concentrating 
  • Struggle to recall recent events 
  • Become less fluent in their speech 
  • Make visual mistakes and misperceptions, for example seeing a rug as a pond
  • Experience mood swings including depression and anxiety.
