3a. Overview of Dementia Types
As we learned in the previous lesson, dementia is an umbrella term used to describe several conditions that affect the brain. There are many disorders that cause dementia, and each can have its own unique symptoms and signs.
Some disorders are known as progressive dementias. These are disorders that grow progressively worse over time and are not reversible.
Progressive Dementias
- Alzheimer’s disease
- Vascular dementia
- Lewy body dementia
- Frontotemporal dementia
- Mixed dementia
Other disorders can be linked to Dementia
- Huntington’s disease

We will also explore substance abuse-induced dementia, which is not always considered a progressive dementia.
