Cognitive training for schizophrenia in developing countries: a pilot trial in Brazil

Area of Science:

• Neuroscience
• Psychiatry
• Cognitive Psychology

Background:

• Cognitive deficits significantly impair schizophrenia patients' quality of life.
• Existing cognitive training programs are primarily developed in high-income countries, limiting accessibility in developing nations.
• Cultural and economic factors pose challenges for adopting Western treatment models in diverse settings.

Purpose of the Study:

• To investigate the efficacy and feasibility of a novel cognitive training program for schizophrenia tailored to a developing country context.
• To assess if a low-resource intervention can improve cognitive functions in stable Brazilian schizophrenia patients.
• To evaluate the program's potential for wider adoption in resource-limited settings.

Main Methods:

• A pilot, double-blind, randomized controlled trial was conducted.
• The intervention involved a 5-month group-based attention and memory training program using simple, accessible materials.
• Seventeen stable Brazilian patients with schizophrenia participated, with weekly sessions.

Main Results:

• The cognitive training group demonstrated significant improvements in inhibitory control and set-shifting.
• Both groups showed enhancements in processing speed, selective attention, executive function, and long-term visual memory.
• The control group exhibited improvements in long-term verbal memory and concentration.

Conclusions:

• Cognitive training for schizophrenia can be effectively implemented using minimal resources and infrastructure, making it suitable for developing countries.
• This approach shows promise for improving cognitive functions in schizophrenia patients within resource-constrained environments.
• The findings support the development and adaptation of culturally relevant cognitive interventions for schizophrenia globally.
