Sleep Apnea Connected to the Higher Risk of Dementia

A recent research, published in the European Respiratory Journal, finds that sleep apnea, a common disorder that interferes with the breathing while sleeping, is connected to the changes in brain structure similar to changes seen in early dementia.sleep apnea increases the risk of dementia

For the study, 83 participants were involved with the age from 51 to 88. They reported memory and mood problems to their doctors. None of them was diagnosed with obstructive sleep apnea (OSA) They underwent memory tests and MRI brain scans.

Having analyzed the received data, the scientists concluded that a low level of oxygen in blood during sleep was associated with the loss of thickness of the right and left temporal lobes of the brain. These brain structures play important role in memory processes and proved to be changed in dementia.

Cheap Drugs May Help Prevent Dementia after a Stroke

A new research from the University of Edinburgh, UK, suggests that cheap cilostazol tablets may reduce damage to arteries, which lead to blood clots, resulting in strokes and cognitive decline.cheap drugs may reduce risk of dementia

The researchers plan to assess the medications’ ability to cut the risk of lacunar strokes and dementia within the next three years.

Dr. Doug Brown from the Alzheimer’s Society says: “With no new dementia drug in 15 years – but one person every three minutes developing it – the race is on to find desperately needed drugs that can prevent people getting dementia. Finding an existing drug which can prevent dementia would be a huge breakthrough.”

Eating Vegetables, Fruit, and Fish May Keep Your Brain Sharp

A new study finds that brain volumes of people who regularly eat vegetables, fruit, and fish are on average 2ml greater than brain volumes of those who often drink sugary beverages. A brain volume reduction of 3.6ml equals to one year of aging.vegetables keep your brain sharp

For the study, the researchers from Erasmus University, Rotterdam, analyzed diets of 4,213 adults with an average age of 66 who didn’t have dementia. The participants also had to take scans to determine their brain volumes.

Dr Meike Vernooij, the author of the study, says: “People with greater brain volume have been shown in other studies to have better cognitive abilities, so initiatives that help improve diet quality may be a good strategy to maintain thinking skills in older adults.”

These Common Drugs Associated with the Risk of Dementia

A new study, led by the University of East Anglia (UEA) in the United Kingdom, suggests that a class of common drugs used to treat such conditions as depression, incontinence, and gastrointestinal disorders connected to the higher risk of developing dementia in the future.common drugs linked to dementia

For the study, which is considered to be the largest study of the alleged link, the researchers used medical data of more than 300,000 persons over the age 65. This sample included around 50,000 patients with dementia.

Study leader Dr. George Savva, who works in the School of Health Sciences at UEA, explains: “This research is really important because there are an estimated 350 million people affected globally by depression, and bladder conditions requiring treatment are estimated to affect over 13 percent of men and 30 percent of women in the U.K. and [United States].”

Blood Test to Detect Alzheimer’s Disease before Symptoms Appear

A group of researchers claims that they are close to developing a blood test that will be able to detect the Alzheimer’s disease long before the symptoms appear.blood test

One of the main problems in treating the Alzheimer’s disease is that it is always diagnosed at a relatively late stage as the symptoms may develop over the many years.

In a recent study, published in the journal EMBO Molecular Medicine, researchers wanted to understand whether measuring the relative levels of healthy and pathological amyloid-beta in the blood could identify Alzheimer’s disease at its early stages.

The initial phase of the study demonstrated promising results – in participants who showed subtle early symptoms of the Alzheimer’s disease, the test detected changes in levels of amyloid-beta that associated with abnormal deposits visualized using brain scans.
