Impaired olfactory function—a declining sense of smell—is associated with mild cognitive impairment (MCI) as well as Alzheimer’s disease (AD). A recent study reveals that olfactory functioning naturally weakens in healthy older adults and is impaired, in terms of odor identification, in people with neurodegenerative conditions such as MCI and AD.

The search for ways to prevent and treat Alzheimer’s disease (AD) has been a long and arduous process. Although progress is being made in many areas, years of research still have not produced therapies that can stop or reverse the steady advance of this mind-wrecking neurodegenerative disease.
Yet scientists are accruing
Chances are the majority of older Americans would agree to undergo a test that would tell them if they’re likely to develop Alzheimer’s disease (AD), even if it delivers bad news. That’s the conclusion of a study in which 875 men and women aged 65 and older were asked if
You read and hear a lot about dietary fats these days: Some are “good,” some are “bad,” and there are conflicting recommendations about how much is safe to eat. How do you sort this out when you’re in the grocery store, or it’s time for dinner?
“In a perfect case of
Your genetic background is responsible, at least in part, for your propensity to inherit certain medical conditions, including Alzheimer’s disease (AD) and other dementias. The more family members you have who are affected by certain types of dementia, including Alzheimer’s, the greater your risk becomes. So, strictly speaking, is dementia
Impaired olfactory function is associated with mild cognitive impairment (MCI) and Alzheimer’s disease (AD). Olfactory functioning (sense of smell) declines in healthy older adults, and is impaired, in terms of odor identification, in people with neurodegenerative conditions, such as MCI and AD.
Previous studies have shown that neurodegeneration can affect brain
The critical difference between Alzheimer’s and dementia is that Alzheimer’s is a specific disease and dementia is a term used to describe symptoms that can be caused by a number of different diseases, including Alzheimer’s disease (AD). So, the answer to the question, “Is there a difference between Alzheimer’s and
Various dementia types can be caused by medical or psychiatric conditions, among them high fever, vitamin deficiency, head trauma, or depression. These are the so-called “reversible dementias.” Other dementia types are irreversible and—if you’re wondering, “Is dementia hereditary?”—can be caused by family genes.
Let’s look at reversible dementias first. It’s important
Sleep disorders can be caused by internal factors, such as medical problems, or by external factors, such as stressful situations. Some sleep disorders affect your ability to get to sleep and stay asleep, while others disrupt the structure of your sleep.
The most common sleep disorders by far are insomnia and
Lewy body dementia (also known as dementia with Lewy bodies, or DLB) affects up to 25 percent of individuals with progressive dementia in the United States, ranking second behind Alzheimer’s disease (AD). Yet most of us know little about this irreversible neurodegenerative disease.
Because early Lewy body dementia symptoms are difficult
