Abstract/Results: | ABSTRACT:
Huntington's disease (HD) is associated with a loss of the ability to recognize emotions. Recent studies have shown controversial findings regarding a selective impairment for recognition of disgust in presymptomatic HD patients. The current study was aimed at defining the role of visual search behavior in this deficit.
A group of 9 early stage HD patients, 14 presymptomatic HD patients and 21 healthy control subjects were tested. They all did an extensive battery of neuropsychological tests and Huntington's patients were assessed with the UHDRS-motor examination. For the visual tasks, first, we used a forced choice emotion recognition task, in which participants had to indicate whether an image reflected a specific emotion or not. Second, we included a similar emotion recognition task, in which only limited facial information was available to recognize an emotion (i. e. mouth or eye region was masked). These masked tasks were designed to define whether the subject's performance altered when forced to look at a specific component of the face. Finally, a commonly used test of emotion recognition (FEEST) was used, in which participants had to evaluate a face by choosing between six emotions. Each task included the six basic emotion categories: disgust, fear, surprise, anger, sadness and happiness.
Behavioral results demonstrated no difference in the ability to recognize any of the six basic emotions between presymptomatic gene carriers and healthy controls. Thus, the finding that presymptomatic HD patients have a selective impairment of disgust could not be supported. Moreover, an emotion recognition impairment was found in the early stage HD patients for all of the six emotions. Interestingly, even in the masked task conditions, their emotion recognition ability was significantly impaired. This leads to the conclusion that the emotion recognition impairment in symptomatic HD patients is not the result of a deficit in attention guidance to specific features of a face.
