As any caregiver will know, Alzheimer's disease is associated with enormous changes in the mood, behavior, sleep patterns and activities of daily living in the person affected. Some of these symptoms have been associated with disturbances in the circadian rhythm - the term used to describe the 24 hour cycle of our biological processes. Evidence suggests that this inbuilt timing system is very sensitive to both light levels and the hormone melatonin.
A study out this month highlighting the importance of bright lighting to improve the circadian rhythm of elderly people, showed a modest improvement in their symptoms of dementia. The research, by Rixt F. Riemersma-van de Lek, M.D., and colleagues at the Royal Netherlands Academy of Arts and Science in Amsterdam, also found that the additional use of melatonin resulted in improved sleep.
Twelve elderly group care facilities were studied as to the effects of supplementary lighting and/or melatonin over 3 years. Residents with ...

In some countries with universal or nationalized health care, a joint replacement is considered an elective procedure. That means the person chooses to have the operation but it's not an emergency procedure. So despite pain and loss of motion or function, that individual must wait in a queue (line) until the resources are available to them. This could take weeks to months. In the meantime, they are advised to stay active. What's the best way to do that? Should patients exercise on land or in a pool? Is one better than the other? That's what the researchers involved in this study wanted to find out. Physical therapists from down under (Australia) compared patients with hip or knee osteoarthritis exercising either on land (group one) or in a pool-based program (group two) while waiting for surgery. The patients were randomized (randomly placed) into one group or the other. They were all found to be medically fit and able to exercise. Both groups engaged in their respective exercise (land-...
