Ajay Wasan, M.D., M.Sc. – Research
The research of Dr. Wasan is centered on understanding the great variability in treatment response in patients with chronic pain, seen in most populations with chronic painful illnesses.
There is little understanding of which patients respond best or least to various medications, nerve block procedures, or rehabilitation programs for chronic pain, such as chronic low back pain. His research focuses on whether comorbid psychiatric illness (a highly prevalent comorbidity) is an important predictor of pain treatment and a predictor of the neural patterns of brain activation associated with processing painful stimuli. He also has an interest in developing standardized measures (patient surveys and physical exams) to quantitatively describe the variability in symptoms and signs in patients with neuropathic pain. Quantitative sensory testing and functional MRI are important tools of physiological investigation Dr. Wasan incorporates into his studies. In his studies he often combines quantitative measures with qualitative research to provide a detailed description of the phenomena he studies. He has ongoing studies examining predictors of opioid analgesia, prescription opioid misuse, and nerve block response.He is also validating a method for standardized examinations in neuropathic pain.He has begun work using fMRI to describe neural activations patterns in the brain associated with chronic low back pain.His work is funded by NIH, industry, and private foundations.
