    Summary
    This summary is machine-generated.

    Attention Deficit Disorder, Residual Type (ADD-RT) in adults is common and identifiable by symptoms. However, biological markers and symptom severity do not validate ADD-RT as a distinct clinical entity.

    Area of Science:

    • Neuroscience
    • Psychiatry
    • Clinical Psychology

    Background:

    • Attention Deficit Disorder, Residual Type (ADD-RT) is a diagnosis within the DSM-III criteria.
    • Adult ADD-RT presents unique challenges in diagnosis and understanding.

    Purpose of the Study:

    • To investigate the clinical characteristics and biological correlates of Attention Deficit Disorder, Residual Type (ADD-RT) in adults.
    • To determine the validity of ADD-RT as a distinct clinical entity.

    Main Methods:

    • Evaluation of 22 adults diagnosed with ADD-RT using DSM-III criteria.
    • Comparison with matched control groups.
    • Assessment of personality, psychological factors, methylphenidate blood levels, growth hormone response, and brainstem evoked response.

    Main Results:

    • Specific personality and psychological factors were characteristic of the ADD-RT group.
    • Methylphenidate blood levels, growth hormone response, and brainstem evoked response did not differentiate ADD-RT subjects from controls.
    • Socioeconomic status and IQ predicted outcome, but not symptom severity.

    Conclusions:

    • While ADD-RT adults are identifiable by symptoms, biological measures do not support its status as a distinct clinical entity.
    • Male subjects with ADD-RT appeared more homogeneous than female subjects.
    • Further research is needed to clarify the diagnostic validity and underlying mechanisms of adult ADD-RT.
