  • Vascular: stroke.
  • Genetic: neurofibromatosis.
  • Immune: multiple sclerosis.

Do brain lesions cause dementia?

Conclusion White matter lesions, especially in the periventricular region, increase the risk of dementia in elderly people. Cerebral white matter lesions (WML) in elderly people are thought to result from small-vessel disease and are considered to be a risk factor for dementia.
