The study of genetic contributions to cognitive and behavioral disorders is having some success and is likely to proceed at a quick pace increasing research interactions among clinicians, psychologists, and neuroscientists.
It is likely that correlations will be discovered between genetic defects and specific anomalies in brain structure and behavior. What is likely to be more problematic will be the quick unraveling of the relationships between normal gene function and normal behavior. Complete understanding of intervening structure and development of the brain, as well as the myriad environmental influences, are likely to make this job a slow one over the next decades.
