Now simple blood test to detect risk of dementia

Now simple blood test to detect risk of dementiaWashington, Feb 10 - Now you can test the possibility of developing dementia with a prick of a needle. As opposed to cardiovascular diseases, where the level of cholesterol in our blood indicates the risk of cardiac arrest, there are no such trustworthy markers in our blood in terms of diagnosing the risk of dementia setting in.


Eyes are window into dementia

Eyes are window into dementiaWashington, Aug 26 : A new study has found that changes in the eye could help predict dementia, even before the symptoms show.

According to the researchers from Gladstone Institutes and University of California, San Francisco, loss of cells in the retina could be used as an early marker for frontotemporal dementia (FTD), prior to the onset of cognitive symptoms.


Statins could cut dementia risk by 25 pc

Statins could cut dementia risk by 25 pcLondon, April 14 : Scientists have revealed that statins drugs can slash the risk of dementia by a quarter.

Chewing linked to lowered dementia risk

Chewing linked to lowered dementia riskStockholm, Oct 5 - If you can bite into an apple, then you are more likely to maintain mental abilities and keep dementia at bay, according to a new research.

The older we become the more likely it is that we risk deterioration of our cognitive functions, such as memory, decision-making and problem solving.

Several studies have also demonstrated a link between not having teeth and loss of cognitive function and a higher risk of dementia.


Vitamin C keeps dementia at bay

Eating junk food could also give you dementia

Eating junk food could also give you dementiaLondon, August 30 : Gorging on junk food may not just make you fat but it could also give you dementia, a new study has claimed.

Bad diets are already linked to dementia, through high blood pressure and cholesterol interrupting blood supply to the brain, but the latest theory points to high levels of fatty and sugary food damaging the brain by interrupting its supply of insulin.


Dementia can drain words of meaning

Dementia can drain words of meaningSydney, July 27 - Dementia can impair one's ability to recognise words describing feelings such as 'thrilled' and 'annoyed', according to the latest research.

Sharpley Hsieh and colleagues from Neuroscience Research Australia (NRA) explored how people with different types of dementia comprehend words describing sentiments such as 'doubt' and 'hopeful'.


Too much or lack of sleep could trigger dementia

Too much or lack of sleep could trigger dementia London, July 17 : Those who restrict themselves to seven hours of sleep a night could prevent their brain from ageing by an extra two years, compared with their peers who sleep too much - or not enough, scientists say.

American researchers had found that older women who had managed seven hours a night had far better concentration and memories than those who slept for nine hours.

Those who got less than five hours had been also found to suffer.


Prolonged stress ‘can shrink the brain’ and cause dementia

 Prolonged stress ‘can shrink the brain’ and cause dementia London, Oct 3 : Suffering from stress for long periods of time can shrink the brain and even lead to dementia, researchers have claimed.

Chemicals released by the body during prolonged stress are toxic to brain tissue, they found.

Types of stress linked to the condition include that suffered by those in loveless marriages, dead end jobs and post traumatic situations.


Simple painkillers ‘may lessen agitation in dementia patients’

Simple painkillers ‘may lessen agitation in dementia patients’London, July 18 : Agitation, a common dementia symptom, could be better treated with simple painkillers rather than the riskier `chemical cosh' antipsychotic drugs, according to a study.

It found painkillers significantly cut agitation in dementia patients.

On the other hand, antipsychotics have a powerful sedative effect, can worsen dementia symptoms, and increase the risk of stroke or even death.


Maintaining your overall health may help cut dementia risk

 Maintaining your overall health may help cut dementia riskWashington, July 14: Keeping up with your overall health - including whether a person''s dentures fit properly or they suffer from poor eyesight or hearing - may help reduce the risk for dementia, according to a new research.

Improving and maintaining health factors not traditionally associated with dementia may in fact be key to avoiding the brain disorder, researchers say.


Why elderly dementia patients experience ''Sundowning’

Why elderly dementia patients experience ''Sundowning’Washington, June 28 : ''Sundowning'' is a coming-of-age story, which is characterized by high levels of anxiety, agitation, general activity and delirium among older adults, especially those with dementia, in late afternoon and evening, before they would normally go to bed.


Irregular heart beat plus stroke may increase dementia risk

Irregular heart beat plus stroke may increase dementia riskWashington, Mar 8: A new study has warned that stroke patients who also suffer from an irregular heartbeat are at double the risk of developing dementia.

Findings show that stroke survivors with an irregular heartbeat - or atrial fibrillation - are 2.4 times more likely to develop dementia than stroke survivors without the heart condition.


Shunt surgery ‘improves’ dementia patients’ mental function

Shunt surgery ‘improves’ dementia patients’ mental functionWashington, Jan 26: Swedish researchers have shown that a shunt surgery could improve the mental function and the ability to walk in people suffering from dementia as a result of hydrocephalus and white matter changes.

The study was the first in the world to use a placebo-controlled design to prove the effects of dementia surgery on mental function in hydrocephalus patients.


Green tea ‘fights dementia and cancer’

 Green tea ‘fights dementia and cancer’Washington, Jan 6: A new research by scientists at Newcastle University has suggested that regularly drinking green tea could protect the brain against developing Alzheimer''s and other forms of dementia.

Gene that protects against dementia in high-risk individuals found

Gene that protects against dementia in high-risk individuals foundWashington, Dec 23: Scientists have found a gene that protects against dementia in high-risk individuals.

It was assumed that a mutation in the progranulin gene, which makes the progranulin protein and supports brain neurons, was sufficient to produce a kind of dementia known as frontotemporal lobar degeneration
(FTLD).


Vitamin B may keep dementia at bay

Vitamin B may keep dementia at bayWashington, Aug 18 : University of California-San Francisco researchers have conducted studies to look at the role B vitamins–B-6, B-12 and folate may play in preventing decline in brain function.
