The prevalence of lingual-facial-buccal dyskinesias in the elderly

Institute of Clinical Neurology, University of Bologna, Italy, and I.S.S. (Dr. Manzaroli). Republic of San Marino.

We examined an unselected sample of 398 subjects aged 67 to 87 years. Only six (1.5%) subjects presented lingual-facial-buccal dyskinesias (LFBD). LFBD, therefore, are rare neurologic manifestations. They are more frequent in women than in men and in more elderly subjects. Furthermore, in three of six cases, they were associated with senile dementia. Previous studies performed on hospital-based populations probably overestimated the prevalence of LFBD.
