Most of the time, memory blips are due to normal age-related changes, but sometimes memory complaints can herald the development of mild cognitive impairment (MCI)—a stage of memory loss that represents the first signs of dementia in many individuals. Taking a memory loss test can help determine whether you or

Winter can be a depressing time, especially if you live in a cold northern climate. It’s easy to feel sad when the long, dark days and frigid temperatures keep you cooped up inside. Just about everyone has had the “winter blues” at one time or another. Yet in some people,
Smoking, drinking alcohol, and gastroesophageal reflux disease (GERD) all can increase your risk of throat cancer, but genital human papillomavirus (HPV) has become a leading cause of oropharyngeal cancers in the United States. In fact, some 9,000 people are diagnosed each year with throat cancer that may be caused by
The BRAIN Initiative
Never before has so much science been focused on exploring the secrets of the human brain. In October 2015, the National Institutes of Health announced a second wave of grants to support the Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative, bringing the NIH’s annual investment to $85
There was a time when receiving a cancer diagnosis was tantamount to a death sentence. Any treatment with chemotherapy or radiation could only postpone the inevitable, and only for a relatively short time. Today, that statement no longer holds true for many cancers, including lymphoma, as evidenced by the fact
If your doctor suspects you have heart disease, you may be advised to undergo cardiac tests to diagnose your condition. These tests range from simple, non-invasive screenings to more involved procedures that may include the use of high-tech imaging equipment.
“Typically, these tests are ordered in response to symptoms such as
Another Eye-Scanning Test for AD.
Study results of an eye scanning system (fluorescent ligand eye scanning, or FLES) that detects beta-amyloid deposits on the lens of the eye, conducted by the Banner Alzheimer’s Institute, Phoenix, also were reported at the AAIC. While small—the study comprised only 20 people with probable AD
The classic symptoms of Alzheimer’s disease (AD)—beta-amyloid plaques and tangles—are detectable as much as 15-20 years before clinical diagnosis via a retinal imaging device developed at Cedars-Sinai Medical Center, Los Angeles, CA. The test is noninvasive and could lead to earlier treatment, researchers say.
Earlier diagnosis could “increase our chances of
Alzheimer’s research has made great strides in recent years. Scientists have found new ways to diagnose the disease while it’s still in its early stages. Blood tests and brain scans may be able to spot the presence of beta-amyloid and other Alzheimer’s markers before symptoms appear. And although no definitive
It is becoming increasingly obvious that there is no simple answer to the question, what causes depression? Is it your brain? Your genes? Your thought patterns? Your life experiences? Likely, it’s all of the above and more.
How the Brain Works
To better understand what causes depression, it helps to have a
