Loneliness and isolation are associated with an increased risk for developing coronary artery disease (CAD) and stroke.

In its 2016 guidelines, the American Academy of Neurology recommended the use of onabotulinumtoxin A (Botox) injections as a way to help reduce the frequency of chronic migraines.

A class of drugs commonly used in over-the-counter and prescription drugs to treat such problems as insomnia, diarrhea, high blood pressure, depression, and urinary incontinence may be linked to cognitive impairment. Scientists believe the drugs block the neurotransmitter acetylcholine that helps process information, which scientists believe is responsible for the effect. 

Loneliness and social isolation raises your risk of heart attack, stroke, and even early death, says a new study. The risk was similar to light smoking or obesity. 

Getting immediate attention for symptoms of a transient ischemic attack can minimize the risk of a subsequent stroke.

Intermittent tension-type headaches may seem like a consequence of everyday life. Yet you can minimize and even prevent them.

Tension-type headaches can be annoying, but they can often be nipped in the bud by using nonprescription pain relievers.

Compared to migraines, tension-type headaches are a mere annoyance. They tend to be relatively mild and usually aren't accompanied by nausea or oversensitivity to light or sounds. Yet they can occasionally disrupt your day, making it difficult to concentrate on work or enjoy leisure pastimes.

Knowing you have a gene variant that may raise your risk can be distressing. But new research reveals a silver lining.

A particular gene variant that affects cholesterol levels in the blood may influence a person’s risk of both Alzheimer’s and heart disease.

Alzheimer's disease strikes fear in people's hearts, as it gradually erodes a person's ability to remember, think, and learn. There is no cure, and available treatments alleviate symptoms only temporarily. Yet while an estimated 5.3 million Americans currently have Alzheimer's disease, this brain disorder is far less common than heart disease. More than 85 million people in the United States are living with some form of cardiovascular disease or the aftereffects of stroke, which also affects brain function.

Q. Do you think we'll ever be able to prevent Alzheimer's disease?

A. I do. Not because I'm an optimist (though I am) but because of the results of research in the past 25 years.

A negative attitude about aging appears to be associated with a higher likelihood of Alzheimer's disease.

A study in the journal Psychology and Aging examined healthy, dementia-free subjects from the Baltimore Longitudinal Study of Aging, the nation's longest-running scientific study of aging.

Although the two conditions seem unrelated, Alzheimer’s and heart disease actually share a genetic link. People who have a certain gene variant have both a somewhat elevated heart disease risk and a significantly elevated Alzheimer’s risk. Fortunately, a recent study has suggested that when people know they have this variant, they’re more likely to make healthy lifestyle choices that benefit their heart — and what’s good for the heart is good for the brain.
