Alzheimer’s disease, a severe form of progressive dementia, casts a long and fearful shadow on the baby boom generation, but lifestyle changes and advance planning can delay and even diminish its impacts.

A certified Occupational Therapist, Teepa Snow  is a dementia expert who trains and consults for healthcare professionals and families privately. She explains that  while Alzheimer’s is the most widely recognized form of dementia, it is just one of the many forms that condition may take. Here, Snow  (left) describes a few of the others.

Simple forgetfulness is a common trait for most adults, but the early signs of Alzheimer’s are significantly more acute. Here, Teepa Snow breaks down the difference.

The diagram below illustrates the physiological changes that characterize Alzherimer's disease.

Economist Helene Jorgensen thought she had good health insurance, until she got really sick. Having survived both her illness and her direct dealings with hospitals, laboratories and insurance companies, she has written a bluntly critical account of her experiences, both economic and medical, titled Sick and Tired.

In her analysis of the American employer-based heath insurance model, which Jorgensen describes its development as a fluke of history.

That, in turn, fostered the development of the current “fee for service” medical system, which Jorgensen sees as vulnerable to corruption, and horribly wasteful.

Coming from a European perspective, the Danish economist shares in the general distain for a health care system that excludes millions of citizens. But she says the reform measures most widely under discussion in Washington would do little to fix a deeply flawed system.

Marin General Hospital is leaving the corporate umbrella of Sutter Health Care, effective at the end of June. But the separation is proving to be less than amicable.

Dr. Martin Brotman, President of the Sutter Health West Bay Region, is well aware of the criticisms directed at Sutter and their actions in Marin County. He contends those critics fail to give the company credit for the substantial investment it has made in the Greenbrea hospital.

Sutter Health Care’s internal financial maneuvers may be legal, observes Assemblyman Jared Huffman (D-San Rafael), but they do not support the best interests of the communities where the corporation’s hospitals are located.

As the number of African children orphaned by AIDS continues to grow, a new model for housing, teaching and caring for them is trying to take root in Mozambique.

Malena Ruth, Founder and President of the African Millennium Foundation, says that while it is clearly her intention to create opportunities for the orphaned youth and children of her home country, she is just as clear that her vision is not just another orphanage.

Actress  CCH Pounder’s first contact with AMF was as a donor. As she learned more about the organization, she was impressed enough to join their board of directors. And she is now firmly committed to promoting the A Nossa Casa project, because she believes it will begin to make a difference in the near future.

UNICEF has projected that before the end of this year in Mozambique,  more than 926,000 children such as these with have been orphaned by HIV/AIDS.

Even in patients with advanced Alzheimer’s Disease, familiar music from long ago can awaken memories and prompt interactive behaviors. But how does that happen? A U.C. Davis researcher is working to unravel the neural mechanisms within the brain.

Much of the research that has been done so far on how music stimulates the brain has used musical samples that are not particularly stimulating. Dr. Petr Janata, associate professor of Psychology at the UC Davis Center for Mind and Brain, says that a new round of studies should work with recognizable samples, and could discover that the brain encodes different types of music in different ways or areas.

That’s one area of research that Janata hopes to explore himself, along with expanding the studies he’s done on Alzheimer’s patients to include different age groups.

Dr. Peter Janata will discuss his research into “Music, Memories and the Brain"  in a public presentation Friday, Feb. 19 at 8 pm in the Glaser Center in Santa Rosa, a benefit event for the Sonoma County Bach Society.
