The term dementia is a comprehensive word used to describe the symptoms of cognitive impairment. Alzheimer’s disease, while the most common type of dementia, is just one of many variations within the dementia family. There are many types of dementia, including dementia resulting from alcohol misuse, dementia associated with HIV, and dementia resulting from traumatic brain injury. Below we explore the characteristics of and differences among the four most common types of dementia.
Alzheimer’s can be described as a slow process of going backwards in time. The disease process is divided into seven stages, beginning with simple confusion. The later stages can mean significant impairment (e.g., loss of ability to swallow) and the need for full-time care. Early symptoms include:
Also known as Dementia with Lewy Bodies, LBD is another very common, yet frequently misdiagnosed or undiagnosed type of dementia. Symptoms include:
This type of dementia, sometimes called “post stroke dementia,” is very different from Alzheimer’s or LBD. Vascular dementia is brain damage traced to cardiovascular problems, or mini-strokes that have caused bleeding or injury in the brain. Symptoms may be most obvious when they happen soon after a major stroke. The use of medication has been shown to prevent or slow further brain damage. Sudden post-stroke changes in thinking and perception may include:
FTD occurs when there is deterioration to the frontal and temporal lobes of the brain. Symptoms may occur in clusters, and some may be more prevalent in early or later stages. Symptoms include:
