• Biological and physiological correlates of mental illness: multiple papers anchor mental disorder in metabolic and autonomic substrates, linking hyperglycemia, cerebrospinal glucose/sugar content, and sympathetic system activity as underlying mechanisms or markers [3], [4], [5].

• Developmental trajectories and cognitive assessment across youth and educational settings emerge as a central pattern for understanding mental health, through school-child mental health, hookworm-influenced development, tests with delinquents/aboriginal children, and broad IQ development [6], [13], [19], [20].

• Social context, trauma and family dynamics influence mental health: war trauma, public health framing, and family studies [2], [5], [6], [18].

• Psychoanalytic and psychodynamic theories shape understanding and classification of mental illness: psychoanalytic psychotherapy, psychodynamics, and symptomology in psychopathic and endogenous conditions [7], [12], [16], [17].

• Diagnostic frameworks, standardized testing and classification in psychiatry: pedagogical and psychological testing, test features, and psychiatric nomenclature in mental disease [9], [10], [14], [15].
