This is a study to assess the efficacy augmenting cognitive remediation therapy (CRT) with a pharmacological agent for individuals with schizotypal personality disorder (SPD). Impaired cognition, along with functional and social skill deficits, is a core feature of schizophrenia and schizophrenia spectrum disorders. A better understanding of the cognitive and functional impairments in schizophrenia-related conditions, as well as the identification of interventions that can reduce these impairments, are vital to improving outcomes for individual with these disorders.

This study proposes to 1) evaluate the effects of 7.5 weeks of twice weekly cognitive remediation sessions, combined with concurrent administration of 8 weeks of guanfacine/placebo, on performance on cognitive, functional, and social skills performance measures in a sample of SPD patients with proven deficits in these areas. 2) Compare the effect of cognitive remediation therapy + 8 weeks guanfacine with cognitive remediation therapy + placebo on cognition in this schizophrenia spectrum disorder population. 3) Further characterize cognitive impairment in SPD using specific tests of working memory to evaluate the relationship between working memory and functional and social skill outcomes in this population.

Inclusion criteria
Exclusion criteria
Cognitive Remediation Therapy (CRT) will consist of fifteen 45-minute, twice weekly sessions over 7.5 weeks. During each session, subjects, seated at a desk in a private interview room in our research office suite, will work through exercises that are part of the Psychological Software Services CogReHab program. The software to be used is a multimedia, Windows-based program that consists of exercises aimed at improving areas of deficit within the schizophrenia spectrum, such as executive function, working memory, and social cognition.

After completing baseline cognitive testing, subjects will be randomized to guanfacine or placebo. Subjects in the active treatment arm will begin with a guanfacine dose of 0.5mg/day and be titrated up to a maximum of 2mg/day according to our well-tolerated protocol in schizophrenia subjects. The dosing schedule of active guanfacine will be as follows: 0.5mg/d for week 1, 1.0mg/d for week 2, 1.0 mg bid for weeks 3, 4, 5, 6, and 7 and 1.0mg/d for week 8.
After completing baseline cognitive testing, subjects will be randomized to guanfacine or placebo. Subjects in placebo arm will have matching schedule as active arm.
Time frame: Baseline and 7.5 weeks after randomization
Change in score at 7.5 weeks as compared to baseline. MATRICS Consensus Cognitive Battery: Subjects will complete the following MATRICS cognitive assessments.

Change in score at 7.5 weeks as compared to baseline. The SSPA is an office based test designed to measure social competence.
Time frame: Baseline and 7.5 weeks after randomization
Change in score at 7.5 weeks as compared to baseline. This is a measure of adult "mentalising", the ability to attribute mental states to oneself or another person.
