Silent Strokes Can Jeopardize Memory.

 :: Posted by nousdefions on 09-23-2014
BOSTON—The symptoms of a stroke are sometimes obvious, like numbness or weakness on one side of the face, trouble speaking, difficulty walking, and vision problems. Some strokes, though, pass completely unnoticed. But even these can have a significant and lasting effect on memory, reports the Harvard Women’s Health Watch.These so-called silent strokes create pinpoints of dead cells in the brain. The damaged areas are smaller than with a traditional stroke, and often don’t affect areas of the brain associated with movement or speech.

During a typical ischemic stroke, a blood clot blocks a blood vessel that feeds part of the brain. Without a steady supply of blood, cells in that area malfunction and may die. Symptoms that appear reflect the functions that were controlled by the affected part of the brain. A hemorrhagic stroke caused by a burst blood vessel does the same thing. During a silent stroke, the interruption in blood flow occurs in part of the brain that doesn’t control any vital functions. Although it doesn’t cause any obvious symptoms—most people who’ve had a silent stroke have no idea it occurred—the damage does show up on an MRI or CT scan.

Many Men Start Testosterone Therapy without Clear Medical Need

 :: Posted by nousdefions on 04-26-2014

Chevy Chase, MD–Although testosterone use has sharply increased among older men in the past decade, many patients appear to have normal testosterone levels and do not meet the clinical guidelines for treatment, according to new research accepted for publication in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism.

Testosterone is a key male sex hormone involved in maintaining sex drive, sperm production and bone health. Since testosterone levels tend to naturally decline as men age, lower levels of the hormone do not necessarily mean that an individual has hypogonadism, a condition that results from low testosterone. As the population ages and an increasing number of men struggle with obesity and diabetes, more men may experience low testosterone levels without meeting diagnostic criteria or displaying symptoms of hypogonadism.

“Over the past decade, older and middle-aged men are increasingly being tested for low testosterone levels and being prescribed testosterone medications, particularly in the United States,” said one of the study’s authors, J. Bradley Layton, PhD, of the University of North Carolina at Chapel Hill. “While direct-to-consumer advertising and the availability of convenient topical gels may be driving more men to seek treatment, our study suggests that many of those who start taking testosterone may not have a clear medical indication to do so.” Read the rest of this entry »

10 Things You Need to Know After Your Child Is Diagnosed with Autism

 :: Posted by nousdefions on 04-01-2014

NEW YORK (March 26, 2014) — In recognition of Autism Awareness Month, Dr. Catherine Lord, director of the Center for Autism and the Developing Brain at NewYork-Presbyterian Hospital, and a national authority on autism spectrum disorders (ASD), offers families guidance and tips for coping with a child’s diagnosis.

Have hope. Every day we learn more about how to help people with ASD.
Remember that your child is an individual. Your child is first and foremost his or her own unique person, then a child, then a child with strengths and difficulties, and only then a child with ASD.
Build a strong support system. Find people you can trust to support you as an individual, and then to support you as a parent of a child with autism.

Find credible sources. You will hear many contradictory and unfounded pieces of information. Find professionals and resources in which you have faith. Read the rest of this entry »

Let sleep burn away brain fog, from the March 2014 Harvard Health Letter

Boston, MA —Struggling with fuzzy thinking and a faltering memory? Try this rejuvenating and risk-free approach—sleeping more—to help burn away brain fog, reports the March 2014 Harvard Health Letter.

“Poor sleep has an adverse impact on thinking,” says sleep expert Dr. Lawrence Epstein, an instructor in medicine at Harvard Medical School. “This is true whether it’s due to a lack of sleep or a sleep disorder.”

Lack of sleep can interfere with attention, concentration, and reaction time. Going without sleep for 48 hours harms thinking skills as much as a blood alcohol concentration of 0.1%, which is above the legal limit for driving in every state. Read the rest of this entry »

Doing Yourself Harm

Recently, there has been much ado about an article appearing in the January 8, 2012 Sunday New York Times Magazine by William J. Broad entitled, All Bent Out of Shape, The Problem With Yoga.

The article examined the numerous reasons why so many people are getting injured while practicing yoga. The author quotes a world-renowned instructor as saying, “the vast majority of people should give up yoga altogether. It’s simply too likely to cause harm.”

 
According to the country’s top yoga experts, reasons for the increased number of injuries include; not enough qualified instructors to meet the demand, too many students in a class, the introduction of nontraditional styles like “power” yoga, applying the western mindset of to-always-want-more and unfit overweight individuals trying to use yoga as a way of getting into quick shape.

The rising injury rate is not just limited to yoga. This phenomenon has also been noted in other exercise methods including dance aerobics, Pilates and even in the more conventional activities like weightlifting.

Simple Steps for Boosting Energy, from the Harvard Men’s Health Watch

 :: Posted by nousdefions on 06-20-2013

BOSTON—Some days do you feel like the Energizer Bunny with a weak battery—starting strong but unable to keep going and going? There are several ways to help boost flagging energy, like pacing activities, taking power naps, and eating healthfully, according to the June 2013 issue of the Harvard Men’s Health Watch. One thing that doesn’t work: taking overhyped dietary supplements.

Sometimes fatigue is due to a medical condition. If that’s been ruled out, here are a few basic steps to maintain energy throughout the day:

Set a steady pace: With age, the energy “battery” may not be able to store quite the charge it used to. “It’s fully charged but it’s smaller and you have fewer hours of energy in it,” says Dr. Fabiny, chief of geriatrics at Cambridge Health Alliance and an assistant professor of medicine at Harvard Medical School. “If you try to do all the things you did in the past, you could end up feeling tired.” Instead of burning through the battery in two hours, spread it out between morning tasks, afternoon tasks, and evening activities—with rest and meals between.

The Immense Value of Exercise

 :: Posted by nousdefions on 06-20-2013

By Mark William Lisky

According to information provided by the National Center for Health Statistics (NCHS), the leading five causes of death in the U.S. from birth to middle age in descending order are all-cause accidents, birth defects, cancer, homicide and heart disease. Aside from accidents which holds a very high constant at the number one spot until about age forty-five, the other causes have some crossover peaks and valleys.

At about the age of ten, death by birth defects fall rapidly and is replaced by cancer. During one short period between the ages of twenty-five to thirty-five, suicide overtakes cancer at the number two spot for mortalities. Deaths from liver disease spike shortly above both homicide and suicide at age fifty.

Apart from some of these fluctuations, there is a startling change between the ages of forty-five and  fifty-five. Accidents, liver disease, homicide and suicide begin to disappear from the radar. These are replaced in descending order by cancer, heart disease, stroke, respiratory diseases and falls. Eventually, after age sixty-five, heart disease beats out cancer as the number one killer of men and women.
