Emotion recognition in objects in patients with neurological disease

Area of Science:

• Neuroscience
• Psychology
• Art Therapy

Background:

• Individuals with dementia often exhibit impaired emotion recognition in others.
• Frontotemporal dementia (FTD) and Alzheimer's disease (AD) are neurodegenerative conditions impacting cognitive functions.
• Understanding the nuances of emotional processing deficits is crucial for patient care.

Purpose of the Study:

• To investigate the ability of patients with frontotemporal dementia (FTD) and Alzheimer's disease (AD) to detect emotional qualities in art.
• To compare the emotional recognition abilities in art between FTD, AD, epilepsy patients, and healthy controls.
• To determine if deficits in interpreting art's emotions are specific to FTD.

Main Methods:

• A cohort of 52 FTD patients, 20 AD patients, 18 epilepsy patients, and 159 healthy controls were assessed.
• Participants completed a novel test evaluating recognition of emotions in art (music, paintings), sensory pleasantness, and aesthetic judgments.
• A subset also underwent testing for recognizing emotions in human faces.

Main Results:

• FTD patients demonstrated a significant deficit in recognizing emotions in art compared to healthy controls and AD patients.
• This deficit in FTD was specific to art interpretation and not explained by difficulties with sensory pleasantness or aesthetic judgment.
• AD patients did not show significant deficits in art emotion recognition, though some approached significance.
• Epilepsy patients showed no deficits in any tested domain.

Conclusions:

• Frontotemporal dementia (FTD) is associated with a specific and significant impairment in interpreting emotional messages conveyed through art.
• This artistic emotional deficit in FTD parallels known deficits in recognizing emotions in other people.
• These findings enhance understanding of FTD's impact on emotional processing and daily life for patients and caregivers.
