Outcome Measures

Primary Outcomes (1)

  • Overall Cognitive Improvement Z-score

    Participants were administered an eight-test neuropsychological test battery at baseline and end-of-study. The battery included the following tests: working memory: WAIS-III Letter-Number Sequencing and Brief Assessment of Cognition in Schizophrenia Number Sequencing; verbal memory: California Verbal Learning Test (CVLT); visual memory: Brief Visuospatial Memory Test (BVMT); motor speed: Grooved Pegboard; processing speed: WAIS-III Digit Symbol and WAIS-III Symbol Search; and the Gordon Diagnostic System CPT. Alternate forms of the CVLT and BVMT were used for the two test occasions. For each neuropsychological test, participant scores were converted to z-scores: z = (score - baseline mean)/baseline SD. For the primary outcome measure, an overall composite z-score was computed from the average of the individual test z-scores. A positive z-score would reflect better performance compared to baseline; a negative z-score would reflect worse performance compared to baseline.

Eligibility Criteria

Age18 Years - 60 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • DSM-IV diagnosis of either schizophrenia or schizoaffective disorder.
  • Males and females
  • Age: 18 and 60
  • Caucasian or Non-Caucasian
  • Subjects will be currently treated with one of the following new generation antipsychotics: olanzapine, risperidone, quetiapine, ziprasidone, or aripiprazole.
  • Subjects will meet a priori criteria for cognitive impairment severity. The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) will be used to determine the level of cognitive impairment. Patients will meet entry criteria if they have a RBANS total score of 90 or less (one standard deviation below the normal control mean).

You may not qualify if:

  • History of an organic brain disease
  • History of DSM-IV alcohol or substance abuse (within the last month), or DSM-IV alcohol or substance dependence (within the last six months).
  • Pregnant women and women taking oral contraceptives (because of the theoretical risk of breakthrough ovulation).
  • Current treatment with galantamine or other acetylcholinesterase inhibitor (e.g. donepezil)
  • History of a second or third degree atrioventricular (AV) block.
  • Persons with chronic medical conditions, which are unstable.
