Today we give an overview of Fetal Alcohol Spectrum Disorder (FASD), which includes a collection of disorders that occur when a fetus is exposed to alcohol. We discuss this topic with Jeffrey Wozniak, Ph.D., a neuropsychologist with extensive research and clinical experience in FASD.

Dr. Wozniak is a Professor, Head of the Psychology Division, and a clinical child neuropsychologist in the Department of Psychiatry at the University of Minnesota where he sees patients with a variety of neurodevelopmental, neurological, and psychiatric conditions. He also trains graduate students and clinical psychology interns in the practice of clinical neuropsychology. Dr. Wozniak’s research focuses on Fetal Alcohol Spectrum Disorders. He directs the University’s FASD Research Program, which conducts neuroimaging, neurocognitive, and intervention studies in FASD. He is the past-president of the Fetal Alcohol Spectrum Disorders Study Group (FASDSG) and is involved with the Collaborative Initiative on FASD (CIFASD), which is an ongoing multi-site imaging, neurobehavioral, genetic, and facial dysmorphology project.
Dr. Wozniak and his team also work to inform the public about the dangers of prenatal alcohol exposure and to train local physicians and other professionals in diagnosing and assisting affected individuals.
