This study has been terminated.

DESCRIPTION: (Verbatim from the Applicant's Abstract) Abnormalities of eye movement control and spatial cognition are well-established deficits in schizophrenia. However, the regional disturbances in brain function causing these deficits are not yet known. This application proposes a series of integrated behavioral studies designed to identify causes of deficits in schizophrenia.

Condition Intervention
Schizophrenia Drug: Antipsychotic

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Basic Science
Official Title: Clinical and Computational Studies of Dopamine Function in Schizophrenia

Primary Outcome Measures:
  • Positive and Negative Syndrome Scale (PANSS) Score Change From Baseline. [ Time Frame: Baseline and 6 weeks ]
    Positive and Negative Syndrome Scale (PANSS) Total Score. 1 to 7 on 30 different symptoms based on the interview as well as reports of family members or primary care hospital workers. PANSS Total score minimum = 30, maximum = 210 Higher scores represent more severe symptoms. A positive change score (baseline-6 weeks) indicates an improvement in symptoms.

Enrollment: 12
Study Start Date: June 2009
Study Completion Date: November 2011
Primary Completion Date: November 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Antipsychotic
Drug: Antipsychotic
Risperidone is the first line antipsychotic followed by others per clinician choice. Flexible dosing QD x 4-6 weeks.

Detailed Description:
We will be assessing clinical symptoms and cognition before and after treatment.

Ages Eligible for Study:   15 Years to 64 Years   (Child, Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Inclusion Criteria: Inclusion criteria for this study are (1) able and willing to give written informed consent; (2) no contraindications to MRI (cardiac pacemaker, aneurysm clip, cochlear implants, IUD, shrapnel, history of metal fragments in eyes, neurostimulators or other metal devices, weight of 250lbs or more, claustrophobia) and (3) medically stable. Sedation will not be used for MRI studies because cooperation is essential.

Exclusion Criteria:

  • Any subject is excluded from the imaging studies if they have any contraindications to MRI such as cardiac pacemaker, aneurysm clip, cochlear implants, pregnancy in the later stages (because of body size and limited comfort for MRI studies), IUD, shrapnel, history of metal fragments in eyes, neurostimulators, weight of 250 lbs. or more, or claustrophobia. Individuals with mental retardation, neurologic disease or significant medical illness that might effect neuronal or vascular physiology will not be recruited.
