Are there Dementia Prevention methods that work? This is the question everyone wants to know the answer to. While there is no one way to prevent dementia, researchers continue to research how to prevent dementia. There is good evidence that living a healthy lifestyle can help lower your risk of dementia.
What is Dementia?

Dementia is used to describe symptoms that affect your memory, thinking, and behavior. These symptoms will start to interfere with performance of everyday activities. It usually develops in individuals over 65 years old and is known as a late-life disease.
Early signs of dementia will often go undetected and become noticeable over time. It is a progressive disease that currently has no cure. While there are many different types of Dementia, Alzheimer’s Disease, Vascular Dementia, Lewy Body Dementia, and Parkinson’s Disease Dementia are the most common.
What causes Dementia?
Several factors can cause dementia.
One of the causes of dementia is when brain cells and neurons begin to die because connections are lost. Proteins in the brain form plaques and tangles, the nerves die, and brain tissue is lost.
Trauma can also cause dementia. This can be from strokes, brain tumors, or head injuries. The damage then causes the cells in the brain to die.
Dementia can also be from depression, Vitamin B12 deficiencies, thyroid issues, or drug or alcohol use.
The good news about all this is that understanding the risk factors and possible dementia prevention may help prevent it as you age.
Risk Factors of Dementia

Dementia Prevention

#1. Physical Activity
Being physically active in your life is one of the best ways to reduce the risk of dementia. It is good for different parts of your body, including your heart, weight, mental wellbeing, and circulation.
When you are not physically active, you are at a greater risk of developing heart disease, being overweight, and type 2 diabetes. All put you at a greater risk of developing dementia.
What to do: It is recommended that you get at least 150 minutes of moderate-intensity aerobic exercise each week. This can include many different activities including, walking, cycling, swimming, tennis, pushing the lawnmower, and dancing. Consider strength training twice a week. Things like yoga and gardening can also be great options.
While it may be hard to get started at first, try to get up and move around more than you currently are.
