Health Alert: New alzheimer's drugs needed

(CBS)- Researchers say there is an urgent need for the development of new Alzheimer's drugs. A review at the Cleveland Clinic finds more than 99 percent of medications developed over the course of a decade have failed.  Now the pipeline for new therapies is nearly dry.  The study says 44 million people around the world suffer from Alzheimer's and that efforts for drug development need more support.

(CBS)- A good brisk walk may improve the symptoms of Parkinson's disease.  A study in the journal neurology looked at patients with mild to moderate cases, who walked three times a week for 45 minutes.  Researchers say the exercise improved motor function as well as mood, fatigue, and some mental abilities.

(CBS)- For people with type 2 diabetes, combining different types of exercise may be best.  A study found evidence that aerobic exercise combined with resistance training may be most effective for controlling both blood sugar and blood fat.  Researchers in Austria reviewed more than a dozen trials, involving about a thousand patients.

(CNN)- There have been a lot of questions about childhood vaccinations out there and it can be overwhelming to parents, but a new study comes down to the numbers, so parents will want to listen up.  The study in the medical journal, Pediatrics, takes a big stand that children should absolutely get their vaccines, period. The researchers poured over more than 20,000 scientific titles and 67 different papers to reach what they believe is the most comprehensive conclusion. They found no ties between vaccines and the rising number of children with autism. Research showed that negative side effects from vaccines only affect a small fraction of people.
