As we age, our cognitive abilities tend to decline. It's unfortunate, but normal. Now, a study in about 5,200 cognitively normal, older people living in England shows that this decline is more rapid in individuals with elevated blood sugar levels.
It's well known that air pollution contributes to many health problems, including heart disease, asthma, and other respiratory disorders. But evidence is accumulating that it can also harm the brain, especially as people age, contributing to cognitive decline and dementia.
People with Alzheimer's disease and other dementias often need assistance with such basic activities of daily living as washing, grooming, and dressing themselves. These practical tips can help you provide care while letting your loved one feel comfortable, independent, and respected.
For most people, social interaction is crucial for wellbeing. Yet many individuals with dementia get very little. Findings from a recent study offer a potential solution for encouraging more interaction—at least for ...
There's good evidence that people with chronic hypertension (high blood pressure) are more likely than people without this condition to develop memory loss. Although proving that lowering blood pressure reduces the risk of cognitive decline has turned out to be difficult, preliminary results from a major randomized trial on the topic are generating excitement.
Recent research suggests that a simple blood test to detect beta-amyloid in the brain will be available soon—if you consider the next five years or so to be soon. But will such a blood test be useful in diagnosing Alzheimer's disease?
Two recent studies shed light on ways to optimize your cognitive performance. Here's what the researchers found.
As the severity of the sleep apnea increases, so do levels of beta-amyloid plaque, a hallmark of Alzheimer's disease, according to a study in the American Journal of Respiratory and Critical Care Medicine. This finding suggests that treatment of the sleep condition may reduce the risk of Alzheimer's.
Requiring in-person driver's license renewal visits and vision testing is highly associated with fewer car crashes involving drivers with dementia, according to a study reported in 2018 in Neurology.
People with preclinical Alzheimer's disease (i.e., those with biomarker evidence of the disease but no symptoms) have a good chance of never developing symptoms of full-blown dementia. That's the conclusion of an analysis of several long-term studies in more than 2,000 people reported in 2018 in Alzheimer's & Dementia.
Older people who have seven modifiable cardiovascular risk factors under optimal control are at dramatically reduced risk for dementia, according to a recent French study in ...
People who have a stroke are about twice as likely to develop dementia as people who don't have a stroke, according to a review of studies involving 3.2 million people—mostly older adults—worldwide. The good news is that there are ways to help prevent one.
Thanks to new developments in imaging technology, researchers are now able to use positron emission tomography (PET) scans to search the brain for a protein known as tau. Although tau is essential for normal cell functioning, it can also become dysfunctional and cause the formation of neurofibrillary tangles, abnormal twisted threads, found within the brain nerve cells of almost all people with AD.
Not all memory loss is irreversible. Loss of memory can result from medication side effects, depression, certain medical conditions, and other controllable causes.
The holidays are upon us. If you're planning to get together with family in the days and weeks ahead, here are some things you can do to help a loved one with Alzheimer's take part—if she or he would like to do so. Keep in mind that these tips can help strengthen family ties at any time of the year.
