Several studies have reported impairment in the recognition of facial expressions of disgust in patients with Huntington's disease (HD) and preclinical carriers of the HD gene. The aim of this study was to establish whether impairment for disgust in HD patients extended to include the ability to express the emotion on their own faces. Eleven patients with HD, and 11 age and education matched healthy controls participated in three tasks concerned with the expression of emotions. One task… 

Beyond emotion recognition deficits: A theory guided analysis of emotion processing in Huntington’s disease

Padova Emotional Dataset of Facial Expressions (PEDFE): A unique dataset of genuine and posed emotional facial expressions.

This dataset tries to fill the gap in scientific research on emotion by providing a considerable amount of dynamic genuine and posed clips of the six universal emotions from 56 participants, and has been validated by 122 human raters.

Huntington’s Disease

Huntington’s disease is a neurodegenerative disorder with progressive motor, cognitive, and neuropsychiatric impairments. There is evidence that problems in both motor speech and language affect

Disgust as a disease-avoidance mechanism.

The authors find strong support for a disease-avoidance account of disgust and suggest that it offers a way to bridge the divide between concrete and ideational accounts of disgust.



Disgust and Huntington's disease

Recognition of facial expressions : Selective impairment of specific emotions in Huntington's disease

Recognition of facial expressions of basic emotions was investigated in HL and UJ, two people with Huntington's disease who showed little evidence of general cognitive deterioration. No impairments

Neural correlates associated with impaired disgust processing in pre-symptomatic Huntington's disease.

The finding of dysfunctional decreased insula activation in pre-symptomatic Huntington's disease provides an explanation for the clinical deficit in recognizing facial expression of disgust and underscores the role of the insula in the emotion of disgust.

Loss of disgust. Perception of faces and emotions in Huntington's disease.

Face perception and emotion recognition were investigated in a group of people with Huntington's disease and matched controls, showing that the recognition of some emotions is more impaired than others and disgust is a prime candidate.

Neural structures associated with recognition of facial expressions of basic emotions

The results support the hypotheses derived from neuropsychological findings, that recognition of disgust, fear and anger is based on separate neural systems, and that the output of these systems converges on frontal regions for further information processing.

Impaired recognition of disgust in Huntington's disease gene carriers.

People who were free from clinical symptoms and did not perform significantly more poorly than non-carriers on any of the background tests, on any other face processing tasks, and even for recognition of any other basic emotion points strongly to the importance of the basal ganglia in the emotion of disgust.

Neural responses to facial and vocal expressions of fear and disgust

The findings support the differential localization of the neural substrates of fear and disgust and suggest a possible general role for the perception of emotional expressions for the superior temporal gyrus.

A specific neural substrate for perceiving facial expressions of disgust

Functional magnetic resonance imaging was used to examine the neural substrate for perceiving disgust expressions and found the neural response to facial expressions of disgust in others is thus closely related to appraisal of distasteful stimuli.
