#2 Lewy Body Dementia

Lewy Body dementia has a pattern of decline that may be similar to Alzheimer's disease. Lewy Body dementia includes initial or early symptoms such as sleep disturbances, followed by Parkinsonian-like tremors and stiffness, as well as visual hallucinations.

#2/5

#3 Vascular Dementia

Vascular dementia results from brain damage caused by multiple strokes. The symptoms overlap with Alzheimer's disease, and memory loss may not be as seriously apparent. Impaired judgment or ability to make plans is more likely to be the initial symptom.

#3/5

#4 Frontotemporal Dementia

Frontotemporal dementia begins inside the forehead area of the brain and has symptoms including changes in personality and behaviour, and difficulty with language. Symptoms generally develop at a younger age (approximately 60) and people affected survive for fewer years than those with Alzheimer's.

#5 Mixed dementia

Increasing evidence indicates that many people have "mixed dementia," which means more than one disorder is present. The most common combination is Alzheimer's disease and Vascular dementia.
