Stiff-Man Syndrome

Results of Interviews and Psychologic Testing

Received November 14, 1996; revised February 26, 1997; accepted April 7, 1997. From the Department of Psychiatry and Psychology, Mayo Clinic and Mayo Foundation, and the Zumbro Valley Mental Health Center, Rochester, Minnesota.

Thirteen patients with stiff-man syndrome (SMS) were studied with the Minnesota Multiphasic Personality Inventory (MMPI), the Self-Administered Alcoholism Screening Test (SAAST), the State-Trait Anxiety Inventory (STAI) profiles, and by telephone interviews. The mean MMPI, SAAST, and STAI were within normal limits; however, several patients had abnormal profiles. The results of telephone interviews revealed that 8 patients (62%) had been given at least 1 psychiatric diagnosis and 4 (31%) abused alcohol or were dependent on it. Two patients had a psychiatric diagnosis that preceded the onset of symptoms of SMS. The authors hypothesize that SMS patients have a -aminobutyric acid deficiency or GABAergic neuron dysfunction that leads to psychiatric symptoms, including depression and chemical abuse. Clinicians treating patients with SMS must be alert to the possible presence of comorbid psychiatric illnesses in this patient population.
