Two new Alzheimer's treatments offer hope. One is the drug PBT2, which prevents brain metals from driving production of plaques and tangles. The other is Neuro AD, a therapy combining electromagnetic brain stimulation with cognitive training.
People with a 70% blockage in the carotid artery and symptoms such as a mini-stroke may want to have surgery to unblock the artery sooner rather than later. Other options include angioplasty with stent placement and blood-thinning medicines.
Living at 6,000 feet of altitude causes the heart to work more efficiently. It results in more oxygen-carrying red blood cells and less fluid in the blood.
High-tech imaging tests that use computed tomography (CT) scans to determine heart health may play a valuable role in patients who are at intermediate risk. If the imaging test results are abnormal, that can push a person into a high-risk group.
Depression and obesity are linked. Obesity affects parts of the brain that regulate mood. Low energy and low motivation from depression can translate into less activity and exercise. The result may be weight gain.
Topical nonsteroidal anti-inflammatory drugs (NSAIDs) can bring weeks of pain relief without the risks of oral NSAIDs. Topicals are best for people who have occasional joint pain, when other methods of treatment have failed.

Prostate cancer screening should not be offered routinely to all men. For some men, the resulting treatment-which can produce side effects-is worse than the disease.
Blepharoplasty removes drooping excess skin and fat around the eye that comes with aging. The surgery is meant to change a person's appearance to create a more youthful look or to improve a person's vision.
Actinic keratoses look minor, but they can progress to skin cancer. Treatment involves freezing, scraping, chemical peels, medicated creams, or photodynamic therapy. Treatment is almost always successful.

In November 2012 the FDA approved a new treatment for people with rheumatoid arthritis called tofacitinib (Xeljanz). Unlike previous biologic treatments, the new drug is a pill, not an injection, and it targets another type of inflammatory molecule.
Stop leg wounds that don't heal
Venous leg ulcers are the final stage in the progression of venous disease. Treatment involves compressing the swelling out of the leg using either bandages or compression stockings with dressings on top of the broken skin.
Are painkillers also killing your hearing?
Frequent and long-term use of pain relievers, such as ibuprofen (Advil, Motrin) or acetaminophen (Tylenol), may be a risk factor for hearing loss. Researchers say the drugs may damage the cochlea, the snail-shaped hearing mechanism in the inner ear.
What you should know about: Magnesium
