Deryk Beal, PhD, R-SLP, CCC-SLP, joins Peter Reitzes to discuss brain imaging research, related research and stuttering. Dr. Beal is asked about structural and functional brain imaging research with people who stutter. Dr. Beal is asked to consider this research in relation to gender, severity, recovery, persistency, covert stuttering (passing as fluent), singing, cerebral dominance, other speech disorders (such as apraxia), treatment, relapse and much more. Deryk also discusses deep brain stimulation and direct current stimulation.

DR. DERYK BEAL is an Assistant Professor in the Department of Speech-Language Pathology and Audiology and the Executive Director of the Institute for Stuttering Treatment and Research (ISTAR) at the University of Alberta in Edmonton, Canada. Dr. Beal’s research program aims to understand the neurobiological origins of speech production, stuttering and associated disorders of speech motor control at multiple levels of organization. Deryk’s ultimate goal is to leverage this knowledge for improv cal treatment via genetic risk assessment for dysfluent speech and the development of novel pharmaceutical and neurorehabilitative interventions.
