Binding action and emotion in first-episode schizophrenia

Area of Science:

• Neuroscience
• Cognitive Psychology
• Psychiatry

Background:

• Social cognition deficits are common in early schizophrenia (SCZ).
• Mirror neuron-driven embodied simulation (mnES) may be impaired in SCZ.

Purpose of the Study:

• Investigate alterations in mnES in first-episode SCZ patients.
• Examine the impact of emotional cues on mnES in SCZ.

Main Methods:

• Functional magnetic resonance imaging (fMRI) was used.
• 22 SCZ patients and 22 healthy controls (HCs) observed goal-related actions in neutral and emotional contexts.

Main Results:

• SCZ patients showed reduced frontoparietal network activity during neutral action observation.
• Reduced left inferior parietal lobule activation in SCZ correlated with self-experience disturbances.
• Angry agent actions led to poorer right anterior insula activity in SCZ, correlating with empathy scores.
• Happy agent actions did not reveal significant differences.

Conclusions:

• Emotional cues partially restore mnES in SCZ patients.
• Deficits in understanding emotional components of others' actions persist in SCZ.
