Research on the Alternate Neurobiological Models of ADHD

Due to the behavioral heterogeneity of ADHD cases, there has yet to be a uniform model that may provide a well-rounded reference. This review focuses on four representative neuropsychological theories that have been advanced so far: the State Regulation Theory, Delay Aversion Theory, Dynamic Developmental Theory, and Dopamine Transfer Deficit Theory. By examining their key propositions as well as interpreting their implications for symptom representations, this paper evaluates their validity as ADHD models relative to each other. In conclusion, the Dynamic Developmental Theory offers comprehensive postulates that may be applied to explain the most ADHD symptoms in comparison to the other models assessed.
