Developmental Brain Dysfunction: Revival and Expansion of Old Concepts Based on New Genetic Evidence
Resumo:
Neurodevelopmental disorders can be caused by many different genetic abnormalities that are individually rare but collectively common. Specific genetic causes, including certain copy number variants and single-gene mutations, are shared among disorders that are thought to be clinically distinct. This evidence of variability in the clinical manifestations of individual genetic variants and sharing of genetic causes among clinically distinct brain disorders is consistent with the concept of developmental brain dysfunction, a term we use to describe the abnormal brain function underlying a group of neurodevelopmental and neuropsychiatric disorders and to encompass a subset of various clinical diagnoses. Although many pathogenic genetic variants are currently thought to be variably penetrant, we hypothesise that when disorders encompassed by developmental brain dysfunction are considered as a group, the penetrance will approach 100%. The penetrance is also predicted to approach 100% when the phenotype being considered is a specific trait, such as intelligence or autistic-like social impairment, and the trait could be assessed using a continuous, quantitative measure to compare probands with non-carrier family members rather than a qualitative, dichotomous trait and comparing probands with the healthy population.

Application of knowledge about psychological development should, ideally, be theory based. As such, these applications represent “natural ontogenetic experiments”; the results of the evaluation of such interventions feed back to the theory, helping to support, falsify, or refine the ideas from the theory which led to the particular application. Such applied developmental intervention research is central within a currently popular perspective of life-span human development. Thus, applied developmental intervention research provides critical tests of such key concepts within this life-span perspective as: plasticity; multidirectionality; the synthesis of continuous and discontinuous processes across ontogeny; contextual embeddedness; and the role of individuals as agents in their own development. This paper elucidates some of the major features of the dynamic linkage between applied developmental psychology and this view of life-span human development. Key elements of this life-span perspective and the facts of developmental intervention, as seen from this perspective, are specified. Finally, the doctoral training program at the authors' institution is presented as one example of how this link may be institutionalized in the form of graduate education.
