According to Dr. Levinson’s almost 50 year research effort, Dyslexia is not just a severe reading disorder characterized by reversals as currently defined. Nor is it due to brain damage or abnormal cellular formations scattered throughout vital processing centers of the thinking brain or cerebral cortex. And it’s not due to an impaired reading processor within the language area of the brain failing to understand the normal and clear reading-related signals assumed received. Nor is it due to acquired alexia in adults, something many experts still believe.
In other words, were dyslexia similar to alexia, a severe reading comprehension impairment of proven higher brain processing origin, the IQ and prognosis of dyslexics would be very limited and poor as in alexics. In fact, whereas alexics have definite localizing neurological evidence of a thinking-brain or cerebral cortical impairment — limiting their prior IQ, creative and reasoning abilities, the very opposite is found true for dyslexics. The IQ’s of dyslexics may be superior and many, as you will soon read, are highly gifted, creative — and even become famous. And to date, all experts have completely failed to find any definite neurological signs of a thinking-brain deficit in dyslexia similar to the one in alexia, despite a century of trying.
