The relation between attention and tic generation in Tourette syndrome.

Misirlisoy E, Brandt V, Ganos C, Tübing J, Münchau A, Haggard P - Neuropsychology (2014)

Bottom Line: During the "freely tic" condition, patients had significantly fewer tics when attending to finger movements, or to the ensuing colors, compared with when attending to their tics.During tic suppression, tic frequency was reduced to an equal level in all conditions.Focusing attention away from tics significantly reduces tic frequency.

Mean number of tics per trial for each task condition and baseline. Black connecting lines indicate significant differences between freely tic conditions, and gray connecting lines indicate significant tic reductions when inhibiting tics within an attention condition (* p < .05. ** p < .01. *** p < .001). The freely tic baseline had significantly greater tics than all within-task freely tic conditions (dashed lines, p < .05, Bonferroni corrected). There were no differences between baseline tic inhibition and within-task tic inhibition conditions. Note that no difference was found between freely tic and tic inhibition states in the finger attention condition.

fig2: Mean number of tics per trial for each task condition and baseline. Black connecting lines indicate significant differences between freely tic conditions, and gray connecting lines indicate significant tic reductions when inhibiting tics within an attention condition (* p < .05. ** p < .01. *** p < .001). The freely tic baseline had significantly greater tics than all within-task freely tic conditions (dashed lines, p < .05, Bonferroni corrected). There were no differences between baseline tic inhibition and within-task tic inhibition conditions. Note that no difference was found between freely tic and tic inhibition states in the finger attention condition.

Mentions: The mean number of tics per trial in each task condition is shown in Figure 2. A 2 × 3 repeated measures ANOVA showed a significant main effect of attention, F(2, 30) = 6.54, p = .004, and a significant main effect of tic inhibition, F(1, 15) = 9.27, p = .008. A Mauchly’s test of sphericity indicated a significant violation for the Attention × Inhibition interaction (p < .05). After applying a Greenhouse-Geisser correction, a significant interaction was found, F(1.41, 21.09) = 5.31, p = .02. We explored this interaction with simple effects t tests. These results are shown in Figure 2.
