TUESDAY, Jan. 14, 2014 (HealthDay News) — A new study challenges previous findings regarding what causes reading problems in children with the common learning disorder dyslexia.
In a new study published online Jan. 14 in the Journal of Neuroscience, lead author Anthony Krafnick and study leader Guinevere Eden, neuroscientists and professors of pediatrics at Georgetown University Medical Center, suggests that the anatomical differences reported in left- hemisphere language-processing regions of the brain appear to be a consequence of reading experience as opposed to a cause of dyslexia.
“These results have an impact on how we interpret the previous anatomical literature on dyslexia,” Krafnick said in the news release. “It suggests the use of anatomical MRI would not be a suitable way to identify children with dyslexia.”
According to Dr. Harold Levinson, these new findings tend to refute the traditional belief that dyslexia is caused by a primary defect in the language processing centers of the left cerebral hemisphere. Pending additional studies, these results further support Levinson’s hypothesis that this disorder is caused by another origin, eg. a primary signal scrambling dysfunction of cerebellar-vestibular dysfunction secondarily impairing normal cerebral processing.
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, Long Island, 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. Initially supported by Nobel Laureate Sir John Eccles and other outstanding cerebellar neurophysiologists and inner-ear scientists, Levinson’s research has more recently been independently validated worldwide by highly sophisticated neuroimaging brain studies.
