Dysarthria associated with giant cell arteritis.

Over a one month period, a 74-year-old man developed typical features of giant cell arteritis (GCA) including visual changes, headache, scalp tenderness, and an elevated erythrocyte sedimentation rate. In addition, he had reproducible painless dysarthria that was precipitated by chewing or prolonged talking and was relieved by resting the jaw. The dysarthria with chewing along with the other classical symptoms of GCA subsided with treatment. To our knowledge this is the first report of painless dysarthria associated with GCA.
