http://www.ncbi.nlm.nih.gov/pubmed/24189200 A Magnetic resonance brain imaging study by Harvard researchers revealed only cerebellar volume reductions in ADHD adults never previously treated, further validating Levinson's cited 1990 cerebellar/ADHD data and theory. According to Dr Levinson, credited with initially proposing the cerebellar-vestibular theory of LD, dyslexia and related ADHD, this well conducted study highlights and reviews the important role of the cerebellum in communicating with the entire cerebral cortex and most other important brain structures. Although most investigators of ADHD have focused primarily on the frontal cerebral cortex, these researchers having obvious clinical experience have been able to explore and provide a more holistic perspective frequently absent from too many other studies. Levinson further claims, "They are only a step away from scientifically also explaining the many overlapping or comorbid cerebellar disorders found complicating ADHD."

About Harold Levinson, M.D.

Formerly Clinical Associate Professor of Psychiatry at New York University Medical Center, Dr. Harold Levinson is currently Director of the Levinson Medical Center for Learning Disabilities in Great Neck, New York. He is a well known neuropsychiatrist, clinical researcher and author. His "highly original" research into the cerebellar-vestibular (inner-ear) origins and treatment of dyslexia and related learning, attention-deficit/hyperactivity and anxiety or phobic disorders has evolved over the past four decades. Levinson's concepts encompass the collective insights derived from the examinations, follow-up and successful treatment of over 35,000 children, adults and even seniors and have led to new methods of screening, diagnosis, treatment and prevention. His expanded theories appear capable of encompassing and/or explaining all reported symptoms as well as most other concepts and experimental data, thus resulting in a truly holistic perspective.
