Dementia Causes And Risk Factors

In most cases genetic risk factors come from small influences of many genes rather than one mutation being responsible for. Vascular dementia is caused by reduced blood flow to the brain which damages and eventually kills brain cells.

There is a strong case for further research into the effect of air pollution on brain health.

Dementia causes and risk factors. Key Risk Factors. A single stroke where the blood supply to part of the brain is suddenly cut off. Researchers have discovered several important factors that affect our risk of developing dementia.

Risk Factors for Dementia Geneticsfamily history. What are risk factors. Adipose fat tissues have the potential to cause narrowing within the arteries leading to heart attack or stroke.

The most common causes include Alzheimers disease Parkinsons disease vascular dementia Lewy body dementia frontotemporal dementia and severe head injury. The biggest risk factor for dementia is age and the older you are the more likely you are to develop the condition but it is not an inevitable part of ageing. There is evidence that tiny air pollution particles can enter the brain but at this time we cant say if they play a role in the development of dementia.

In most cases it is likely that our age genes medical history and lifestyle all contribute to our risk of dementia. Risk factors on their own are not causes of a disease. The causes and risk factors for dementia include older age genetics history of head trauma lower education the risk factors for heart and vessel disease many reversible and irreversible medical conditions infections medications alcohol and other drugs and nutritional deficiencies.

2020 Report of the Lancet Commission These are key risk factors -- many arising later in life but some sooner -- for dementia-- Less education in early. Modifying 12 risk factors could delay or prevent up to 40 of dementia cases according to an evidence analysis in the updated Dementia Prevention Intervention and Care. Researchers have discovered a number of genes that increase the risk of developing.

The short answer is that the risk of developing dementia is related to a combination of genetics and lifestyle with age being the biggest risk factor. Generally speaking dementia is caused by changes in or damage to the brain. Modifiable risk factors include.

The reason is that being overweight negatively impacts our vascular health. Air pollution has been a focus of several studies on cognitive impairment and dementia risk. However although getting older is undeniably the biggest risk factor for dementia research suggests up to one in three cases of dementia are preventable.

Atherosclerosis is the. Some ways to reduce these risk factors are. These include age and genetics but also medical conditions and lifestyle choices.

Dementia can be caused by a variety of issues including vascular problems and the build up of proteins called alpha-synuclein and Pick bodies in the brain. Several recent studies have found that smoking significantly increases the risk of mental.
