Types of dementia

Dementia is a wide term used to describe the loss of memory and other mental capabilities in a way that prevents the person suffering from dementia from fully engaging in life. It is caused by physical changes in the brain.

There are many different kinds of dementia:

Frontotemporal dementia (FTD)

Frontotemporal dementia, or frontotemporal degenerations are terms that are referring to disorders which are physically created by a progressive death of nerve cells in the brain’s frontal lobes (behind the area of the forehead) or its temporal lobes (the area in the brain that is located behind the ears).

The damage that is caused to the nerve cells in people who suffer from frontotemporal dementia manifests as a difficulty in communication- speaking and verbalizing, producing and comprehending language.

Lewy body dementia (LBD)

Lewy body dementia is a progressive kind of dementia that manifests as a gradual decline in one’s ability to focus, reason, concentrate and solve problems, due to abnormal microscopic deposits that create a huge damage to the brain cells.

The symptoms of Lewy body dementia mainly include difficulties in thinking and reasoning, but also confusion, anxiousness and alertness that might change significantly from one moment to the other

Other symptoms of Lewy body dementia are more related to the physical functioning: slowness of movement, imbalance in walking, lack of coordination and disorientation.

Vascular dementia

Vascular dementia is caused by a reduction in blood flow to certain regions in the brain, depriving them from oxygen and nutrients, and results in severe difficulties in thinking and concentrating.

The impact of vascular dementia varies widely, from minor to highly severe, depending on how much damage has been created in the brain. Memory loss is a significant symptom of vascular dementia, although not the only one.

The symptoms of vascular dementia can be very obvious, when they start soon after a brain stroke, and includes severe confusion, trouble concentrating, difficulty speaking or understanding language, disorientation and poor balance.
