There are many different factors that can contribute to developing dementia.

Age – As a person gets older the chances of developing Alzheimer’s disease, vascular dementia and several other dementias increases. Genetics – Research has proven that there are a number of genes that can be inherited that will increase the risk of developing dementia.

Smoking and Alcohol abuse – Studies have found that smoking significantly increases the risk of mental decline and dementia. People who smoke are at a greater risk of vascular disease which may be the underlying dementia risk. Drinking large amounts of alcohol also appears to increase the risk of developing dementia.

Atherosclerosis - This affects the delivery of blood circulated to the brain and can lead to a stroke. Cholesterol - High levels of bad cholesterol appears to increase the chance of a person developing vascular dementia. Plasma Homocysteine - Research shows that a person with a higher than average type of amino acid known as plasma homocysteine is a high-risk factor for the development of Alzheimer’s disease and vascular dementia. Diabetes – Diabetes is another high-risk factor that can be attributed to both Alzheimer’s disease and vascular dementia.

Mild Cognitive Impairment – People with this condition do not necessarily develop dementia however they do have significantly Down syndrome – Studies have found that most people with Down syndrome develop characteristic Alzheimer’s disease plaques and neurofibrillary tangles by the time they reach middle age, many also develop dementia symptoms
