Alzheimer's disease (AD) is a dementing illness, clinically characterized by progressive memory loss and impairment in conducting the activities of daily living. Many scientists believe that AD results from an increase in the production or accumulation of a specific protein in the brain (so-called beta-amyloid) that causes death of nerve cell. Loss of nerve cells in strategic brain areas, in turn, results in deficits of certain neurotransmitters, which are the brainís chemical messengers.

The main risk factor for AD is increased age. Other risk factors are genetic disposition, oxidative stress as well as a number of medical conditions such as depression or cerebrovascular diseases.

Rapid advances in basic scientific and clinical knowledge have led to the development of specific drugs against AD. TULSA CLINICAL RESEARCH, LLC in Tulsa, Oklahoma, is currently conducting various research studies with promising new agents for the treatment of patients in all severity stages of Alzheimer's disease.
