Northwest Neurological offers quality care and research leadership for patients with neurological conditions.

The providers at Northwest Neurological are dedicated to developing new treatments for neurological disorders. Dr. Greeley and Dr. Aldred have over 29 years of combined experience conducting clinical trials for Parkinson’s disease, Alzheimer’s disease, dystonia, movement disorders, migraine, stroke, and many other conditions. We partner with government agencies and pharmaceutical groups to bring cutting edge research for these conditions to Spokane and the Inland Northwest.

Research Collaboration

Memory in Older Adulthood and Parkinson’s Disease Research Program

Northwest Neurological is proud to collaborate with researchers at Washington State University on their Memory in Older Adulthood Parkinson’s Disease Research Program. Researchers are examining different types of cognitive and memory abilities and how they relate to activities that older adults are involved with every day. The goal is to better understand cognitive disorders in older adulthood and Parkinson’s disease, and to develop programs and assistive technologies to help maintain independent living.

Please consider being a participant in this important study! For more information, call (509) 335–4033 (Washington State University Cognitive Aging and Dementia Laboratory).

Awake Versus Asleep Deep Brain Stimulation (DBS) Study

Contact our office (call (509) 458-7720) if you have an interest in deep brain stimulation. We’ll ask some questions to determine whether you qualify to be a candidate in our research trial for awake versus asleep DBS.
