There are three stages, early, middle and later, as a person goes through the stages the symptoms will worsen. In later stages, falls, loss of mobility and struggling to speak are common too.


Vascular Dementia

Vascular Dementia is a condition caused by the lack of blood that carries oxygen and nutrient to a part of the brain. It causes problems with reasoning, planning, judgment, and memory. It contributes to around 20% of all Dementia cases, and is much more common in males. Similarly to Alzheimer’s Disease, there is no cure but treatments to help manage the condition.
