Cognitive Training, and Aerobic Exercise Keith H. Nuechterlein, - - PowerPoint PPT Presentation

Successful Treatments for Early Psychosis: Consistent Antipsychotic Use, Supportive Education/Employment, Cognitive Training, and Aerobic Exercise

Principles of Individual Placement and Support (IPS) Model (Robert Drake & Deborah Becker)

• Work rehabilitation is integral

component of mental health treatment, not separate (job specialist w/in clinical team)

• Goal is competitive employment in

typical work settings

• Emphasis is on obtaining jobs directly,

rather than after lengthy pre- employment training

Principles of Individual Placement and Support (IPS) Model (Robert Drake & Deborah Becker)

• Continuous vocational rehabilitation

services based in real work experiences

• Follow-along support to sustain

employment

• Services based on consumers’

preferences and choices

• Outreach into community

Medication Non-Adherence (from Peter Weiden)

• 50% of patients have significant non-

adherence within one year of beginning treatment.

• 75% within two years.
• 50% of the direct medical costs of

psychiatric hospitalization attributed to non-adherence.

UCLA Study Design

• 12-month randomized controlled trial with first-

episode schizophrenia patients at the UCLA Aftercare Research Program

• Patients received Individual Placement and

Support, a form of supported education and supported employment, to provide a context of active work rehabilitation

• After stabilization, patients were randomly

assigned to the medication condition and the psychosocial treatment condition (2 X 2 design)

Pilot Study of Adding Aerobic Exercise to Cognitive Training

• Increasing evidence that aerobic exercise

releases neurotrophic factors (e.g., brain- derived neurotrophic factor) that stimulate synaptic plasticity and enhance learning

• We hypothesize that adding regular

aerobic exercise to neuroplasticity-based cognitive training will increase cognitive gains

Overall Conclusions

• Supported education/employment can

strikingly increase the proportion of patients who return to school or a job after an initial psychotic episode.

• Long-acting injectable antipsychotic

medication is a promising strategy for reducing relapses and improving cognition and everyday functioning in recent-onset schizophrenia.

Overall Conclusions

• Systematic cognitive training can impact

cognitive functioning and everyday functioning in the early course of schizophrenia.

• Aerobic exercise and cognitive training

might have synergistic effects on learning and overall cognitive functioning that enhance the impact of cognitive training alone.
