Many women with hair loss suffer in silence, altering their hairstyle to hide thinning or patches. But the sooner you seek care, the better the chances of successfully treating it, says Mary Gail Mercurio, MD, associate professor of dermatology at the University of Rochester in Rochester, N.Y. It's not as uncommon as you may think: As many as 5% of women under 30 and 60% of those older than 70 are affected, she says. At the recent meeting of the American Academy of Dermatology in Miami Beach, Fla., Mercurio discussed common forms of hair loss in women and treatment options.
LBD is not a rare disease. It affects an estimated 1.4 million individuals and their families in the United States. Because LBD symptoms can closely resemble other more commonly known diseases like Alzheimer’s and Parkinson’s, it is currently widely underdiagnosed. Many doctors or other medical professionals still are not familiar with LBD. LBD is an umbrella term for two related diagnoses. LBD refers to both Parkinson’s disease dementia and dementia with Lewy bodies. The earliest symptoms of these two diseases differ, but reflect the same underlying biological changes in the brain. Over time, people with both diagnoses will develop very similar cognitive, physical, sleep, and behavioral symptoms. While it may take more than a year or two for enough symptoms to develop for a doctor to diagnose LBD, it is critical to pursue a formal diagnosis. Early diagnosis allows for important early treatment that may extend quality of life and independence. LBD is a multisystem disease and typically requires a comprehensive treatment approach. This approach involves a team of physicians from different specialties who collaborate to provide optimum treatment of each symptom without worsening other LBD symptoms. Many people with LBD enjoy significant improvement of their symptoms with a comprehensive approach to treatment, and some can have remarkably little change from year to year. Some people with LBD are extremely sensitive or may react negatively to certain medications used to treat Alzheimer’s or Parkinson’s in addition to certain over-the-counter medications.
Although drug treatment of hypertension is associated with improved survival and decreased vascular complications, drug compliance is a major problem in the control of hypertension. All antihypertensive medications are associated with side effects; thus, it is a physician's responsibility to explain to each patient the side effects of the drugs he prescribes to treat hypertension, and to instill in the patient a sense of necessity for the treatment of hypertension. The choice of antihypertensive drug should be made based on each patient's lifestyle, overall health and ability to tolerate the drug. Ideally, the antihypertensive regimen should be simple, effective, convenient to take and have very few side effects.

A colonoscope is the special tool used to perform a colonoscopy. It is a thin, flexible, tubular ‘telescope’ with a light and video camera that your doctor carefully guides through your colon in order to see and determine the health of your colon. Watch this animation to learn about the features of the colonoscope, how the colonoscopy procedure is performed and how polyps are removed, and the follow-up care you and your doctor should talk about after your procedure.
