Neurofeedback Training for High Risk Psychosis

Processing speed deficits are characteristic of schizophrenia and related to its functional impairment, including in its nascent stages, during a putatively prodromal or clinical high risk period. These cognitive deficits have proven relatively refractory to pharmacologic strategies, though the deficits can be improved with cognitive remediation programs in schizophrenia. The cognitive gains can then generalize to functional improvement, particularly early in the course of illness (i.e. first episode psychosis). Although processing speed deficits are also prevalent in young people identified as at clinical high risk for psychosis (i.e. "psychosis risk syndrome"), and related to their concurrent impaired function and predictive of later psychosis (onset of which occurs in 20-25% of clinical high risk cohorts), little research has focused on how to remediate these deficits in clinical high risk patients. Remediating core cognitive deficits in clinical high risk patients could plausibly address present functional impairment in these young people and moderate illness progression. The investigators propose to conduct a double-blind randomized trial in 105 clinical high risk patients to examine a focal processing speed training program versus an active control in terms of improvement in processing speed and social function, and reduction in prodromal symptom severity.
