Letter to the Editor


We report the case of a 54-year-old right-handed man who presented with a 2-year history of progressive upper-limb weakness with mild dysarthria and prominent involuntary perioral abnormal movements that were characterized as fasciculations. Electromyography disclosed motor neuron disease. The diagnosis of Kennedy’s disease was established by polymerase chain reaction. Perioral abnormal movements and fasciculations may represent important clinical clues to the diagnosis of Kennedy’s disease, particularly when associated with proximal muscle atrophy and gynecomastia. In suspected cases, genetic testing for elevated CAG repeats in the androgen receptor Xq12 gene is warranted.
