D-amphetamine challenge effects on Wisconsin Card Sort Test. Performance in schizotypal personality disorder.. Schizophrenia Research, 20(1-2), 29-32. [doi]
    (last updated on 2019/06/17)

    The authors assessed the effects on Wisconsin Card Sort (WCST) performance and psychiatric symptoms of 30 mg d-amphetamine, a dopamine and norepinephrine agonist, vs placebo in nine patients with schizotypal personality disorder (SPD). Patients, particularly those who made more perseverative errors, demonstrated amphetamine-associated improvement on WCST performance. The data in this preliminary study suggest that some of the cognitive dysfunction present in SPD may improve with amphetamine challenge.
