Dr. Harrington joined HMRI and established the Molecular Neurology Program in 1998. He studies how the cerebrospinal fluid composition explains the intermittent disorder of migraine and the progressive neurodegeneration of Alzheimer’s disease. He also studies molecules that are transported to/from the brain in blood (including changes after mild traumatic brain injury), and those excreted in urine. Mike enjoys collaborating with other clinical and scientific colleagues that apply complementary measures of brain function so as to gain as much information from the same study participants. is approach is important to understand what is causing brain disorder, develop tests that identify disease, and direct treatment to the underlying mechanism.
