| Sumario: | Myasthenia gravis (MG) is a neuromuscular disease of autoimmune etiology and chronic
evolution. In addition to the muscle weakness and fatigue that characterize MG, in some studies
patients show an inferior performance in cognitive tasks and difficulties in recognizing basic emotions
from facial expressions. However, it remains unclear if these difficulties are due to anxious–depressive
symptoms that these patients present or related to cognitive abilities, such as facial recognition. This
study had a descriptive cross-sectional design with a sample of 92 participants, 52 patients with MG
and 40 healthy controls. The data collection protocol included measures to assess recognition of facial
expressions (BRFT), facial emotional expression (FEEL), and levels of anxiety and depression (HADS).
The MG group had worse performance than the control group in recognizing “fear” (p = 0.001;
r = 0.344), “happiness” (p = 0.000; r = 0.580), “disgust” (p = 0.000; r = 0.399), “surprise” (p = 0.000;
r = 0.602), and “anger” (p = 0.007; r = 0.284). Likewise, the MG group also underperformed in
facial recognition (p = 0.001; r = 0.338). These difficulties were not related to their levels of anxiety
and depression. Alterations were observed both in the recognition of facial emotions and in facial
recognition, without being mediated by emotional variables. These difficulties can influence the
interpersonal interaction of patients with MG. |
