Modafinil 200 mg has been studied for its effects on cognitive dysfunction in psychiatric disorders as well, with generally favorable but somewhat mixed results. In a trial of 20 patients with schizophrenia, an 8-week dose of 200 mg/day of Modafinil added to concurrent atypical antipsychotic medication was associated with improvements on the California Verbal Learning Test and a version of the Tower of London task, but not the delayed visual recognition memory test or the Stroop interference test.
