title: Headshaking in a 10-year-old Thoroughbred mare.
abstract: A 10-year-old Thoroughbred mare was presented with a 2.5-week history of headshaking. Based on a thorough physical examination, blood analysis, and a fine needle aspirate of an enlarged thyroid gland, a tentative diagnosis of seasonal idiopathic headshaking was made. Treatment with cyproheptadine was attempted.
