Alzheimer's & Dementia

Alzheimer’s disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills. Alzheimer’s is the most common cause of dementia among older adults. Dementia is the loss of cognitive functioning—thinking, remembering, and reasoning—and behavioral abilities to such an extent that it interferes with a person’s daily life and activities.

Alzheimer’s Disease | Definition, Causes, Diagnosis & Treatment

Alzheimer’s Disease (AD) is the most common form of dementia worldwide (60-70% of all dementia cases) and is a progressive neurodegenerative disorder.

First large-scale stem cell bank created to investigate Alzheimer’s genetic risk factors

Alzheimer's disease (AD) is a common, debilitating neurodegenerative disease affecting about 10 percent of people over the age of 65 and one third of people aged 85 and above. Besides environmental factors, the genes have a strong influence on whether or not a person develops AD during their lifetime.

Short walks after meals deliver big benefits for blood glucose

A randomized crossover trial in healthy young adults found that a 10-minute walk immediately after glucose intake significantly blunted post-meal blood glucose spikes. Both short and longer walks improved overall glycemic control, but only the immediate walk reduced peak glucose levels.

Long-term study confirms lasting benefits of lifestyle changes in preventing diabetes

In the early 2000s the U.S. Diabetes Prevention Program (DPP), a large randomized clinical trial, showed that intensive lifestyle modification was better than a medication called metformin at preventing at-risk patients from developing Type 2 diabetes.

Alzheimer’s protein found to drive lung cancer spread to the brain

Researchers at McMaster University, Cleveland Clinic and Case Comprehensive Cancer Center have uncovered how a protein long associated with Alzheimer's disease helps lung cancer spread to the brain – a discovery that offers hope that existing Alzheimer's drugs could be repurposed in preventing cancer's spread.

New AI tool helps clinicians identify brain activity patterns linked to nine types of dementia

Mayo Clinic researchers have developed a new artificial intelligence (AI) tool that helps clinicians identify brain activity patterns linked to nine types of dementia, including Alzheimer's disease, using a single, widely available scan - a transformative advance in early, accurate diagnosis.

TET2 mutations in blood stem cells linked to lower Alzheimer's risk

A study published in Cell Stem Cell reveals that some mutations in blood stem cells might help protect against late-onset Alzheimer's disease.

Poor lifestyle habits nearly double your chance of developing AFib

A large Framingham Heart Study analysis found that adults with poor cardiovascular health scores on the Life’s Essential 8 were nearly twice as likely to develop atrial fibrillation as those with ideal scores. Maintaining healthy lifestyle habits, especially optimal BMI, blood pressure, and glucose, may help reduce AF risk.

Mediterranean diet wins on weight but misses on memory in diverse aging population

A 14-month randomized trial in older African American adults with obesity found that adopting a Mediterranean diet, with or without calorie-restricted weight loss, significantly improved diet quality and reduced body weight and visceral fat. However, no cognitive benefits were observed compared to usual diet.

Many older adults take aspirin for heart disease prevention without doctor’s advice

Around 1 in 6 older adults take aspirin as their primary method of preventing cardiovascular disease – despite stricter guidelines that no longer always call for it, a study finds.

Shingles and RSV vaccines with AS01 adjuvant reduce dementia risk

Researchers found that older adults who received AS01-adjuvanted shingles or RSV vaccines had a significantly lower risk of developing dementia within 18 months compared to flu vaccine recipients. The protective effect is likely linked to the AS01 adjuvant itself, highlighting new avenues for dementia prevention.
