Cognitive improvement

Researchers successfully reverse Alzheimer’s disease in mice

A team of researchers from the Cleveland Clinic Lerner Research Institute have found that gradually depleting an enzyme called BACE1 completely reverses the formation of amyloid plaques in the brains of mice with Alzheimer’s disease, thereby improving the animals’ cognitive function. The study, which will be published in the Journal of Experimental Medicine, raises hopes that drugs targeting…

In wine, there’s health

Low levels of alcohol might actually be good for your brain

While a couple of glasses of wine can help clear the mind after a busy day, new research shows that it may actually help clean the mind as well. The new study, which appears in the journal Scientific Reports, shows that low levels of alcohol consumption tamp down inflammation and helps the brain clear away toxins, including those associated with Alzheimer’s disease. “Prolonged intake of…

Research examines a different culprit behind Alzheimer's disease

What if one of the prime suspects behind Alzheimer’s disease was a case of mistaken identity? Amyloid plaques, sticky buildup that accumulates in and around neurons in the brain, have long been believed to be an indicator of neurodegenerative disease. Most clinical drug trials for Alzheimer’s disease treatment have failed, presumably because they target these plaques. But according to Raymond…

Old technique & new technology

Optoacoustics: the sound of cells

For centuries, hands, eyes and ears were the physicians’ most important instruments when it came to detecting and diagnosing disease. Today, one of the traditional techniques, percussion, is being revived, supported by state-of-the-art technology and dressed in a new name: optoacoustics. In one of the most exciting visionary ideas in modern healthcare short laser pulses (optics) are transmitted…

Exercising may improve thinking ability and memory

Exercising twice a week may improve thinking ability and memory in people with mild cognitive impairment (MCI), according to a guideline released by the American Academy of Neurology. The recommendation is an update to the AAN’s previous guideline on mild cognitive impairment and is published in the online issue of Neurology, the medical journal of the American Academy of Neurology. The…

Leafy greens vs. Alzheimer's

Putting a fork in cognitive decline

While cognitive abilities naturally decline with age, eating one serving of leafy green vegetables a day may aid in preserving memory and thinking skills as a person grows older, according to a study by researchers at Rush University Medical Center in Chicago. The study results were published in Neurology, the medical journal of the American Academy of Neurology. “Adding a daily serving of…

Just 4,000 steps a day to better brain health

Walking more than 4,000 steps a day can improve attention and mental skills in adults ages 60 and older, according to UCLA research published December 12 in a preprint edition of the Journal of Alzheimer’s Disease. Various studies have found that physical activity is important in preventing cognitive decline and dementia in older adults. Cognitive decline occurs when people start having…

Experimental drug interferes with Alzheimer’s mechanisms

The chemical compound “anle138b” eases cognitive deficits and normalizes gene expression in a mouse model of Alzheimer’s disease. Furthermore, the drug seems to close harmful openings in the membrane of nerve cells. An international collaboration reports these findings in the journal “EMBO Molecular Medicine”. The scientists suggest that anle138b should be validated in clinical trials…

Christmas isolation

Holiday loneliness can be harmful to seniors’ health

The holidays are supposed to be a happy time of the year, but many isolated seniors often are left feeling lonely — which can be harmful to their health. Loneliness is linked to serious medical conditions, including Alzheimer’s disease, stroke and heart disease as well as a higher risk of premature death. But loneliness can be easily overlooked as a health risk because healthcare providers…

Gaming vs. Alzheimer's

Are video games good for older adults' brains?

If you're between 55 and 75 years old, you may want to try playing 3D platform games like Super Mario 64 to stave off mild cognitive impairment and perhaps even prevent Alzheimer's disease. That's the finding of a new Canadian study by Université de Montréal psychology professors Gregory West, Sylvie Belleville and Isabelle Peretz. Published in PLOS ONE, it was done in cooperation with the…

Grim prognosis

Number of americans with Alzheimer’s will more than double by 2060

About 15 million Americans will have either Alzheimer’s dementia or mild cognitive impairment by 2060, up from approximately 6.08 million this year, according to a new study by researchers at the UCLA Fielding School of Public Health. The findings highlight the need to develop measures that could slow the progression of the disease in people who have indications of neuropathological changes…

Clever peptides

Biomarker may predict early Alzheimer’s disease

Researchers at Sanford Burnham Prebys Medical Discovery Institute (SBP) have identified a peptide that could lead to the early detection of Alzheimer’s disease (AD). The discovery, published in Nature Communications, may also provide a means of homing drugs to diseased areas of the brain to treat AD, Parkinson’s disease, as well as glioblastoma, brain injuries and stroke. “Our goal was to…

Protein quality control system

Cellular power outage

A common feature of neurodegenerative diseases are deposits of aggregated proteins in the patient's cells that cause damage to cellular functions. Scientists report that, even in normal cells, aberrant aggregation-prone proteins are continually produced due to partial failure of the respiratory system. Unless they are removed by degradation, aggregates accumulate preferentially in the…

Risks – and benefits – of the Alzheimer’s gene

Scientists drilling down to the molecular roots of Alzheimer’s disease have encountered a good news/bad news scenario. A major player is a gene called TREM2, mutations of which can substantially raise a person’s risk of the disease. The bad news is that in the early stages of the disease, high-risk TREM2 variants can hobble the immune system’s ability to protect the brain from amyloid beta,…

Odor identification problems may be a warning bell for dementia

A long-term study of nearly 3,000 adults, aged 57 to 85, found that those who could not identify at least four out of five common odors were more than twice as likely as those with a normal sense of smell to develop dementia within five years. Although 78 percent of those tested were normal – correctly identifying at least four out of five scents – about 14 percent could name just three out…

$20 million lifestyle intervention trial to prevent cognitive decline

The Alzheimer's Association announced the launch of a $20 million U.S. two-year clinical trial to test the ability of a multi-dimensional lifestyle intervention to prevent cognitive decline and dementia in 2,500 older adults with no current cognitive symptoms but who are at increased risk for later cognitive decline. The announcement was made at the 2017 Alzheimer's Association International…
