Abstract

Comparison was made of the frequency of phobias and panic attacks in normal controls and in patients with Tourette syndrome (TS), attention-deficit disorder (ADD), and ADD secondary to a TS gene. For phobias the most significant difference between controls and TS patients was with respect to fear of public transportation (P = .002), followed by fear of being alone (P = .009), fear of being in a crowd (P = .01), fear of being in water (P = .025), fear of animals (P = .04), fear of public speaking (P = .05), and other fears (P = .05). Only 8.5% of controls had more than three simple phobias and none had more than five, whereas 26% of TS patients had more than three (P = .008) and some had as many as 13. As opposed to 19% of TS patients, none of the controls had phobias that interfered with their life (P = .001). Among female TS patients 55.1% had 3-13 phobias, compared with 8.7% of the female controls (P less than .0005). There was no correlation between the ADD score and the number of phobias (r = -.010) and little correlation with the total number of tics (r = .14). Panic attacks were present in 8.3% of the controls and 33% of the TS patients (P = .0008). This frequency increased to 55.2% (P less than .0005) for grade 3 (severe) TS patients. None of the controls, 15.9% of all TS patients (P = .002), and 31% of grade 3 TS patients (P less than .0005) had more than three panic attacks in 1 wk. Total panic-symptom score (12 possible symptoms) was significantly greater than that in the controls in all grades of TS. The presence or absence of ADD had little effect on the total panic-symptom score, but the presence of ADD resulted in a significantly lower average age at onset of panic attacks (8.8 years) compared with those TS patients without ADD (15.4 years) (P = .03). These observations indicate that phobias and panic attacks are a significant part of the symptomatology of TS and provide the first clear indication that phobias and panic attacks can be due to the presence of a major gene.
