Low concentrations of air pollutants are associated with poorer health, and previous research has found a link between air pollution and dementia risk. Researchers at Karolinska Institutet, among others, have now investigated this connection. The study, published in the journal Neurology, contributes to a better understanding of the biological mechanisms that might explain why air pollution seems to increase the risk of developing dementia.

Older people with ischemic heart disease have an increased long-term risk of dementia and accelerated cognitive decline. A recent study published in Alzheimer's & Dementia: The Journal of the Alzheimer's Association, suggests that the heart, the brain, and cognitive function are connected in the ageing process and that appropriate prevention and treatment of ischemic heart disease in older people might reduce the burden of dementia.

Sugar molecule in blood can predict Alzheimer’sEarly diagnosis and treatment of Alzheimer’s disease requires reliable and cost-effective screening methods. Researchers at Karolinska Institutet have now discovered that a type of sugar molecule in blood is associated with the level of tau, a protein that plays a critical role in the development of severe dementia. The study, which is published in Alzheimer's & Dementia, can pave the way for a simple screening procedure able to predict onset ten years in advance.

Alzheimer’s disease is the most prominent cause of dementia affecting millions of people worldwide. As the changes in the brain function starts 10-20 years before the clinical onset of Alzheimer’s disease, there is a strong interest in the identification of early markers that can be predictive of future mental health/cognitive decline. This may be something that some KI researchers are on the lookout for. Their latest study is now published in Nature Reviews Neurology.

The same genes may be behind cardiometabolic diseases and dementiaBeing affected by several cardiometabolic diseases such as diabetes, heart disease and stroke, is linked to a greatly increased risk of dementia and Alzheimer’s disease. A new twin study by researchers from Karolinska Institutet suggests that the same genes may be behind the risk of both cardiometabolic diseases and dementia. The findings have been published in European Heart Journal.

Alzheimer disease begins decades before any symptoms, such as memory loss, start to show. Consequently, early diagnosis increases the chances of slowing the disease down with drugs. A new study on an inherited form of the disease shows that a protein called GFAP is a possible biomarker for very early stages of the disease. The study, conducted by researchers at Karolinska Institutet and published in the journal Brain, could one day lead to an earlier detection of this serious and common disease.

People with at least two of the diseases type 2 diabetes, heart disease or stroke have double the risk of developing dementia. Prevention of diabetes and cardiovascular disease could therefore be a strategy for reducing dementia risk, a study from Karolinska Institutet published in the journal Alzheimer’s & Dementia suggests.

Elevated heart rate linked to increased risk of dementiaHaving an elevated resting heart rate in old age may be an independent risk factor of dementia, according to a study at Karolinska Institutet published in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association. Since resting heart rate is easy to measure and can be lowered through exercise or medical treatment, the researchers believe that it may help to identify people with higher dementia risk for early intervention.

Clarification on diabetes and dementia riskIt is mainly poorly controlled type 2 diabetes that carries an elevated risk of cognitive impairment and dementia, not the diabetes per se, a longitudinal study by researchers at Karolinska Institutet in Sweden shows. The study comprises over 2,500 people and is published in the journal Alzheimer’s & Dementia: The Journal of the Alzheimer's Association.
News

Researchers at Karolinska Institutet have compared how well different Alzheimer’s biomarkers predict the progression of the disease and its effect on the memory. They found that early accumulation of tau proteins in the brain as measured by PET scanner was more effective at predicting memory impairment than biomarkers in the cerebrospinal fluid or amyloid plaque in the brain. The results are published in the journal Molecular Psychiatry.

Postural hypotension in older adults related to poor cognitionPostural hypotension, a drastic drop in blood pressure when standing up, is linked to an increased risk of dementia and accelerated progression from cognitive impairment to dementia, even in the absence of symptoms, for instance when feeling dizzy or faint. In a study published in the journal Hypertension, researchers from Karolinska Institutet show that postural hypotension could anticipate worse cognition in old age.
