At ERG sites, the principal investigators who helm neurology clinical trials include industry experts, advisors to large pharmaceutical companies, and small biotechs alike. They are joined by neuropsychiatric/neurocognitive raters, certified movement disorder clinicians and raters, licensed clinical psychologists, licensed compounding pharmacists, and a staff specifically trained to work with these populations.


ERG’s dedicated standalone clinical research units offer access to a full spectrum of neuroimaging and psychometric testing for cognitive disorder, as well as APOE genetic testing, onsite cerebrospinal fluid (CSF) sampling and serial CSF sampling capabilities in CLIA-Waived laboratories. We also are able to house both patients and caregivers for short- or long-term clinical research studies.
ERG’s dedicated recruitment team starts with our robust network of referring neurologists, family practitioners, and psychiatrists/ psychologists, as well as community outreach—especially in snowbird locations with large elderly populations. We bolster those efforts by working closely with targeted affiliations, such as the Alzheimer’s Association, the Global Alzheimer’s Platform, the International Essential Tremor Foundation and The Michael J. Fox Foundation. All these recruitment sources simply extend our own robust database of over 215,000 patients, ensuring rapid enrollment for neurological clinical research trials.
