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.

Fish oil capsules have long been suspected of including small amounts of toxic PCBs, but a new lawsuit contends some manufacturers of the supplements contain far more of the banned chemicals than others.

 Oakland attorney David Roe, who filed the suit on behalf of the Eureka-based Mateel Environmental Justice Foundation (known for their actions seeking enforcement of California's Proposition 65) and two other plaintiffs, says it included actions against General Nutrition Center and CVS  Pharmacy stores because it is important that the consumer warnings also be prominently placed in locations where consumers purchase these products.

 Roe says the tests his clients have conducted, and the lawsuit those tests prompted, are also intended to encourage the industry that produces fish oil supplements to do more rigorous testing themselves.

 A new website set up to publicize the lawsuit has details on the  legal action as well as  an online petition calling for stronger labeling requirements. There is also a list of the products tested and  their  test results. A summary graph is shown below.

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.
