Whole system overview

How do biology and context connect to cognitive function? This is an organising model, not one ADHD formula or a diagnostic graph.

Read the diagram explanation and sources

Read from genes and regulation through development, precursor supply, cellular energy, synaptic communication and brain circuits to cognitive performance. Sleep, stress and environment are additional inputs. The connecting arrows organise relationships for learning; they do not demonstrate one causal chain, one defect shared by everybody with ADHD or a diagnostic test.
