Background:
Blepharospasm (BS) is a form of central focal dystonia recently associated with psychiatric disorders, particularly obsessive and compulsive symptoms. Hemifacial spasm (HFS) represents a focal myoclonus with peripheral origin in the facial nerve.
Objective:
To determine the frequency of obsessive and compulsive symptoms in patients with BS in comparison with patients with HFS.
Methods:
30 patients from each group (BS and HFS) followed by the botulinum toxin clinic at the HC-UFPR were evaluated using a structured interview based on the DSM-IV criteria and the Yale-Brown scale. Results were compared by the mean two-tailed t test.
Results:
We found obsessive or compulsive symptoms in 20 (66.6%) patients with BE and 21 (70%) with HFS. Yale-Brown scale scores for each group were higher among BS patients; however, diferences were not statisticaly significant.
Conclusion:
Our study did not show a significant diference in the comparison of the prevalence of obsessive and compulsive symptoms among patients with BS and HFS.
