Working memory assessment in schizophrenia and its correlation with executive functions ability.

Area of Science:

• Neuroscience
• Psychiatry
• Cognitive Psychology

Background:

• Working memory impairment is a common feature of schizophrenia, potentially underlying various symptoms.
• Replication of these findings in diverse populations, such as Brazilian samples, is limited.

Purpose of the Study:

• To assess auditory and visual working memory in Brazilian patients with schizophrenia.
• To determine if auditory and visual working memory function as separate systems.
• To investigate the correlation between working memory deficits and executive functions.

Main Methods:

• A comparative study involving twenty schizophrenia patients and twenty healthy controls matched for gender, age, and education.
• Assessment of auditory and visual working memory.
• Evaluation of executive functions including selective attention, inhibitory control, cognitive flexibility, and planning.

Main Results:

• Schizophrenia patients exhibited significant declines across most evaluated measures, with the exception of inhibitory control reaction time.
• Auditory working memory demonstrated correlations with selective attention, inhibition, cognitive flexibility, and planning.
• Visual working memory showed correlations with planning and cognitive flexibility.

Conclusions:

• The study confirms the presence of working memory and executive function deficits in the evaluated Brazilian schizophrenia sample.
• Executive function impairments may impede the operational capacity of working memory processes in schizophrenia.
• Findings offer insights for developing targeted treatment strategies for schizophrenia within the Brazilian population.
