​​Types Of Dementia

There are different types of dementia, each with different causes and symptoms. Being aware of the common types and their diagnosis could help you to better support your loved one's needs.

​​​​​​​​​What Are The Different Types?

​Alzhei​mer’s DiseaseAlzheimer’s Disease damages brain cells. It is associated primarily with memory loss and other intellectual abilities which interfere with daily life. ​
Vascular Dementia​​Vascular dementia results in the decline of thinking skills due to conditions that block or reduce blood flow to the brain, depriving brain cells of oxygen and nutrients. It is often associated with strokes.
​Lewy Body Dementia​Protein deposits, known as Lewy bodies, develop in nerve cells in regions of the brain involved in cognition, memory and movement. Apart from the symptoms of Alzheimer’s disease, Lewy Body Dementia can result in symptoms similar to Parkinson's disease.
​Fronto-temporal Dementia
Fronto-temporal Dementia refers to a group of disorders caused by progressive nerve cell loss in the front and side regions of the brain, often resulting in personality changes and behavioural issues​
Alcohol-related Dementia​​It is a cognitive disorder caused by severe deficiency of vitamin B1. It is most commonly caused by alcohol misuse.
