Young onset dementia
Dementia beginning before the age of 65 is known as young onset dementia (YOD). Many people assume that Alzheimer's disease and other dementias only affect older people. However, about 1 person in every 1,000 under the age of 65 develops dementia.
Mild Cognitive Impairment
People with mild cognitive impairment (MCI) have problems with memory, language, thinking or judgement that are greater than the cognitive changes associated with normal aging.

Mixed dementia
Mixed dementia has characteristics of both Alzheimer’s disease and vascular dementia. Researchers don't know exactly how many older adults currently diagnosed with a specific type of dementia actually have mixed dementia
Frontotemporal dementia
Frontotemporal dementia tends to occur at a younger age than Alzheimer's disease and can affect both men and women. The average length of the disease can vary. This type of dementia resembles Alzheimer's disease in that it also involves a progressive degeneration of brain cells that is irreversible.
With this form of dementia, a person may have symptoms such as sudden onset of memory loss, behaviour changes, or difficulties with speech and movement.
Lewy body dementia
Lewy body dementia is a form of dementia that occurs because of abnormal deposits of a protein called alpha-synuclein inside the brain's nerve cells. These deposits are called "Lewy bodies," after the scientist who first described them. The deposits interrupt the brain’s messages. Lewy body dementia usually affects the areas of the brain that involve thinking and movement. Why or how Lewy bodies form is
