Alzheimer’s Drug Discovery Offers Fresh Hope

Alzheimer’s Drug Discovery Offers Fresh Hope

In a remarkable medical breakthrough, Scottish research claim to have discovered a new drug which can stop the development of Alzheimer’s disease. The drug –Rember- can slow the patients’ cognitive decline by as much as 81 percent, thus, making it more than twice as effective as any treatment currently available.

The results of the study were presented at the International Conference on Alzheimer’s Disease (ICAD) 2008, in Chicago, Illinois on Tuesday.

321 patients of mild-moderate Alzheimer’s disease from 17 centres across the UK and Singapore took part in the 84-week trail. Patients were randomly assigned to receive the drug - Rember (in either a 30, 60, or 100mg dose) or a placebo, three times a day for 24 weeks.

Once this was completed, patients then received a blinded treatment for a further 60 weeks.

Then, using cognitive tests and brain scans carried out at the beginning of the trial; after 24 weeks and up to 60 weeks later, the researchers monitored the effect on cognitive function of the patients.

Patients receiving a 60mg dose of the drug, Rember, reported a significantly improved cognition, researchers found. Moreover, the effect at 50 weeks was greater than that seen at 24 weeks, thereby, suggesting an improvement in the rate of cognitive decline.

As high as 81 percent cognitive decline was noticed over a period of one year, researchers highlighted.

Rember, also capable of stabilizing the progression of the disease, reduced the decline in blood flow in certain areas of the brain which are first and most severely affected by tau aggregates (the hippocampus and the entorhinal cortex), brain imaging revealed.

By the end of the trial - at 84 weeks – patients receiving a 60mg dose experienced a significantly low cognitive decline compared the other participants from other groups.

The research led by Professor Claude Wischik, chairman of TauRx Therapeutics and Professor of Psychiatric Geratology and Old Age Psychiatry at the University of Aberdeen's Institute of Medical Sciences was carried out by teams from the University of Aberdeen and TauRx Therapeutics, a company based in Singapore.

Alzheimer’s, an increasingly common condition is typically characterized with memory loss, problems with speech and language, difficulty in planning and carrying out normal routine tasks and activities. Alzheimer patients also experience problems with recognition of people and things.

Cancerdefine is one of the most potent diseases and claims millions of lives around the globe every year. Certain kinds of cancer typically affect women only. Here’s themedguru’s low-down on these lady-killers…

Cancers in Women

A cancerdefine is a state of abnormal growth and replication of cells in the body at a certain point. The cell division is a highly regulated process with the new cells getting formed only when the old cells die. However, this process can go off track at times with the continuous growth of new cells at a rate higher than the cell death rate. Thus, the extra cell mass is formed in a tissue or an organ which is called a tumor.

    Heart attack is one of the major causes of women’s death after breast cancerdefine and poses a great threat to women. At least one in three women dies of heart disease or stroke. The fact is that women are as much vulnerable to a heart attack as men.

    Heart-attack in Women – A Silent Killer

    While heart disease becomes significantly prevalent among women after they reach menopause, it can and does affect younger women too. According to the American Heart Association, heart disease kills about 16,000 young women and accounts for 40,000 hospitalizations in young women in U.S. every year. So, women of all ages need to become aware of it and take steps to prevent heart disease.

      Diabetes has a unique impact on the lives of adolescents and requires constant monitoring of blood sugar levels, medication and effects of food and activity. With careful management by diabetologists, nutritionists, and psychologists, and with support from parents, these young people can lead full and healthy lives.

      With proper care, adolescent diabetics can lead full and healthy lives

      The International Diabetes Federation (IDF)’s World Diabetes Day campaign focuses this year on children and adolescents with diabetes. According to IDF, children and adolescents with diabetes face a lifetime of living with a disease that poses particular challenges for them. These struggles include higher insulindefine insensitivity linked to puberty, rapid behavioural changes, increased risk of depressiondefine, anxiety, and low self-esteem and transition to adult services.
