State the term - structural abnormality and unique behavioural

The link between structural abnormality and unique behavioural aberration has become clearer as technological advances have allowed for even more finely tuned discrimination than that obtained from study of gross structural anatomy. This was made dramatically apparent by several early neuropathological studies of dyslexia. The classic diagnosis of dyslexia was based on psychoeducational features until advances in neurological diagnosis enabled identification of associated neuropathological mechanisms and anatomic abnormalities.
