Dementia Causes and Risk factors

  • Dementia
    is a broad term for a range of conditions that involve loss of mental ability and so cause problems with memory, language, behaviour and emotions. Dementia is most common in the elderly. Around five percent of people over the age of 65 are affected to some extent.  According to Alzheimer’s Disease International with increasing life expectancy, this is expected to surge to 75.6 million in 2030. Disease awareness and understanding is a huge challenge

What causes Dementia

The most common cause is Alzheimer's disease, which accounts for up to 60% of all cases. Alzheimer's disease is caused by the destruction of certain brain cells leading to the loss of the neurotransmitter acetylcholine. Vascular dementia, which occurs after a stroke, is the second most common dementia type. But there are many other conditions that can cause symptoms of dementia, such as thyroid problems and vitamin B complex deficiencies. Dementia can also be caused by excessive alcohol intake.

Are you at risk of developing Dementia

Risk factors include:

• Increasing age: As you age, the risks of Alzheimer's disease, vascular dementia and several other dementias greatly increase, especially after the age of 65. However, dementia isn't a normal part of ageing, and dementia can occur in younger people.

• Positive family history: If you have a family history of dementia, your risk goes up by approximately 20-25%. It can be an inherited condition and the gene responsible is the amyloid precursor protein gene (APP)

• Poorly managed high blood pressure

• Brain injury

• Brain tumours

• High cholesterol

• Atherosclerosis: This build-up of fats and other substances in and on your artery walls (plaques) can reduce blood flow to your brain and lead to stroke. Reduced blood flow to your brain can cause vascular dementia. Some research shows there may be an association between blood vessel (vascular) conditions and Alzheimer's disease.

• Diabetes

• Smoking

• Poor diet 

• Excessive alcohol intake

• Vitamin B 12 deficiency

• Down syndrome: By middle age, many people with Down syndrome develop the plaques and tangles in the brain that are associated with Alzheimer's disease. Some may develop dementia.

  • Vitamin D deficiency increases risk of Dementia
    In a population-based study of its kind, a team of researchers has found a link between vitamin D consumption and the risk of developing dementia. Older people who do not get enough vitamin D could double their risk of developing the condition. http://www.medicalnewstoday.com/articles/280704.php
  • Powerful Self-Portraits Reveal Artist's Descent Into Alzheimer's Disease
    Utermohlen's self-portraits provide a stark look at the devastating effects of Alzheimer's. As the artist struggled to keep in touch with the world around him, his works became flatter, more abstract, with a new loss of details and spatial sense. By 2000, Utermohlen's memory and technical skills had deteriorated to the point where his heartbreaking portrayal of himself was simply a scribbled skull and the barest shadows of facial features. http://www.mymodernmet.com/profiles/blogs/william-…

  • New techniques to help identify Dementia earlier
    The most common form of dementia is Alzheimer's, accounting for about two thirds of cases, but it's currently impossible to detect what form of dementia someone has while they're alive. While we are not anywhere near a cure, the ability to deal it earlier would still be useful.  http://www.theguardian.com/science/head-quarters/2014/jul/21/detecting-dementia-dignity-alzheimers
