Phase 3 Alzheimer’s drug increases toxic beta amyloid in the brain — but still provides benefits

Prescription medicineVienna, July 15, 2009 – New insights into how a Phase III Alzheimer’s drug might work were among the advances in potential therapies targeting two abnormal brain proteins – beta amyloid and phosphorylated tau – that were reported today at the Alzheimer’s Association 2009 International Conference on Alzheimer’s Disease (ICAD 2009) in Vienna.

Scientists also reported on how clinicians view and treat mild cognitive impairment (MCI), a research category used to define the state between normal aging and Alzheimer’s, that is now being used widely in clinical practice.

"There are now more than 5 million people living with Alzheimer’s disease in the United States.
