Brief Summary

People with serious mental illness often experience difficulties with thinking skills like memory. These difficulties can make it harder to perform day-to-day activities. The purpose of this study is to test whether combining a type of non-invasive brain stimulation with computerized cognitive exercises is helpful in improving a specific type of memory skill in people who have mental health conditions. The study is a randomized clinical trial, meaning that participants will be randomly assigned to receive either 'active' or 'inactive' brain stimulation. All participants will complete computerized cognitive exercises, also known as cognitive training. Overall, participants will be in the study for 6-8 weeks. The study involves 10 visits to the clinic over 2-4 weeks for cognitive training and either active or inactive brain stimulation. Participants will also complete paper-and-pencil assessments at the beginning and end of treatment, and one month after treatment ends.

Outcome Measures

Primary Outcomes (2)

  • Change in Working Memory Performance - Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) Consensus Cognitive Battery (MCCB) Letter-number Span Total Score

    MCCB letter-number span total raw score. Letter-number span is a subtest of the standardized MCCB and a measure of verbal working memory. Examinees must reorder sequences of numbers and letters spoken out loud by the examiner. Correct responses are counted to create a total score (0-24, where higher scores indicate better performance). For change scores, a positive value indicates improvement (i.e., higher total score).

    Baseline to post-treatment (up to 4 weeks)

  • Change in Working Memory Performance - Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) Consensus Cognitive Battery (MCCB) Spatial Span Total Score

    MCCB spatial span total raw score. Spatial span is a subtest of the standardized MCCB and a measure of visual working memory. Examinees must tap sequences of blocks in the same order as the examiner then in reverse. Correct responses are summed for the forward and backward condition to create a total raw score (0-32, where higher scores indicate better performance).For change scores, a positive value indicates improvement (i.e., higher total score).

    Baseline to post-treatment (up to 4 weeks)

Secondary Outcomes (2)

  • Change in Non-Working Memory Comparison Measures - MCCB Trail Making Test, Part A

    Baseline to post-treatment (up to 4 weeks)

  • Change in Non-Working Memory Comparison Measures - Trail Making Test, Part B

    Baseline to post-treatment (up to 4 weeks)

Study Arms (2)

Active stimulation + cognitive training

EXPERIMENTAL

Participants receive 10 sessions of 'active' non-invasive brain stimulation (tDCS) with concurrent cognitive training (BrainHQ).

Device: tDCS (Active)Behavioral: BrainHQ

Inactive stimulation + cognitive training

SHAM COMPARATOR

Participants receive 10 sessions of 'inactive' non-invasive brain stimulation (tDCS) with concurrent cognitive training (BrainHQ).

Behavioral: BrainHQDevice: tDCS (Inactive)

Interventions

tDCS is a non-invasive procedure in which electrodes are attached to the scalp and send a small direct current to stimulate brain function. Participants in the experimental arm will receive a steady current delivery through the device.

Also known as: transcranial direct current stimulation
Active stimulation + cognitive training
BrainHQBEHAVIORAL

BrainHQ is a web-based, commercially available cognitive training program that includes exercises to enhance working memory

Also known as: cognitive training, computerized cognitive exercises
Active stimulation + cognitive trainingInactive stimulation + cognitive training

tDCS is a non-invasive procedure in which electrodes are attached to the scalp and send a small direct current to stimulate brain function. Participants in the sham arm will wear the device but will not receive a steady current delivery.

Also known as: transcranial direct current stimulation
Inactive stimulation + cognitive training
