1.1.2 Causes of Dementia

Although it primarily affects older individuals, dementia is not a normal part of aging. Damage to brain cells causes dementia. The interfering damage from dementia prevents brain cells from communicating with one another. Thinking, behavior, and feelings might be impacted when brain cells cannot communicate correctly.

The brain is divided into numerous areas, each performing a different function, such as memory, judgment, and movement. Damaged cells prevent a specific region from performing its normal activities.

Certain forms of brain cell damage are linked to specific brain regions and various types of dementia.

For instance, large quantities of particular proteins within and outside of brain cells contribute to Alzheimer’s disease by making it difficult for brain cells to maintain their health and interact with one another.

The hippocampus is a part of the brain that controls memory and learning, and this area of the brain experiences damage first. Because of that, memory loss is frequently one of the first signs of Alzheimer’s.
