About the Memory Health Center

Our goal at the Memory Health Center at Summit Research Network is to expand scientific knowledge as it pertains to memory loss and brain health while maintaining the highest quality patient care. 

Summit Research Network is an independent medical research organization located in the greater Portland, Oregon area. Since 1976, we remain dedicated to improving medical treatment by conducting high quality scientific research and patient care.  We work in cooperation with pharmaceutical companies to develop better future treatments and better health for individuals with medical and mental health conditions.  Our expanded services include the Memory Health Center within Summit Research Network to focus on dementia and other age related memory conditions.

What kind of research is done at the Memory Health Center?

We perform research studies, also known as clinical trials, of approved and investigational medications. Some of these studies are undertaken to enhance our understanding of currently available medications (for example; determining optimal dose schedules). We also conduct research on medications that are not available to the general public except in research studies.

All medications available by prescription in the U.S. must go through this highly regulated, scientific process to evaluate whether an investigational medication can be approved and made available to all.   

Many of our studies involve comparisons between an investigational study medication, and a placebo (inactive substance). Placebo groups are included in some of our studies because the status of patients in the placebo group provides a comparison base for evaluating the effectiveness of active medications. Almost all of the studies at the Memory Health Center require a study partner to accompany the patients to visits. A study partner is usually a close friend or family member and is and a very important part of the research study team.  

Whether on a placebo or the investigational medication, all participants receive all research-related care, evaluations, and supervision by our professional and experienced staff. All of these services are provided at no cost to the patient and health insurance is not required for any study required visits or procedures. In addition, many of our clinical trials provide study participants with a stipend or compensation for time and travel.
