The Causes and Symptoms of Dementia

Dementia is a neurocognitive disorder caused by a loss of memory, ability to think, attention, and logical reasoning, among other mental skills. While certain symptoms of dementia stay consistent, the changes in the brain develop over time in most patients and become severe enough to interfere with day-to-day functioning.

Dementia is most common in the senior population. About 5% to 8% of adults over age 65 have some form of dementia. This percentage doubles every five years after the age of 65. However, dementia is not a part of the natural aging process. Many people live will up to the age of 90 or beyond without exhibiting any signs of dementia.

Causes of Dementia

Dementia is caused by damage to the brain cells that affect the ability of the cells to communicate with one another. When brain cells are unable to communicate, it impacts your thinking, feeling, and behavioral capabilities. The brain has different regions, each responsible for different functions. When cells in a region get damaged, that particular region loses its ability to function normally.

Different types of dementia are linked to types of brain cell damage. For example, Alzheimer's disease is a type of dementia where high levels of proteins in the brain make it difficult for brain cells to communicate and stay healthy. The hippocampus region in the brain is the center of memory and learning, and the cells in this region are often the first to be damaged. Hence, memory loss is one of the earliest signs of Alzheimer's.

The majority of the changes that occur in the brain and lead to dementia are permanent. They worsen with time. However, if your thinking and memory problems are caused by medications, depression, excess alcohol use, thyroid problems, and vitamin deficiencies, they may improve when your condition is addressed.

Symptoms of Dementia

Symptoms of dementia may vary depending on the cause of the condition, but the most common signs include:
