“…It is contingent upon the domain in which risks are presented and rely on personality traits (i.e. impulsiveness), thus refuting the idea that decision-making is a consistent pattern (Bran & Vaidis, 2020; Howat-Rodrigues et al, 2018; Peters, Västfjäll, Gärling, & Slovic, 2006). Therefore, involvement in a real-life risky situation might be contingent upon a need for arousal and sensation-seeking characterised by an attraction to novel experiences (Lauriola, Panno, Levin, & Lejuez, 2014).…”

“…from undesirable and mildly inconvenient to dire and life-threatening. At a decision theory level, risk-taking is rather defined as a tendency to select risky outcomes over safer, sometimes more beneficial ones, in both positive and negative contexts (Byrnes, Miller, & Schafer, 1999; Howat-Rodrigues, Tokumaru, & Izar, 2018). Closely related to the notion of risk and uncertainty is the concept of ambiguity.…”

Decision-making under risk and ambiguity in adults with Tourette syndrome

Background Tourette syndrome (TS) as well as its most common comorbidities are associated with a higher propensity for risky behaviour in everyday life. However, it is unclear whether this increased risk propensity in real-life contexts translates into a generally increased attitude towards risk. We aimed to assess decision-making under risk and ambiguity based on prospect theory by considering the effects of comorbidities and medication. Methods Fifty-four individuals with TS and 32 healthy controls performed risk and ambiguity decision-making tasks under both gains and losses conditions. Behavioural and computational parameters were evaluated using (i) univariate analysis to determine parameters difference taking independently; (ii) supervised multivariate analysis to evaluate whether our parameters could jointly account for between-group differences (iii) unsupervised multivariate analysis to explore the potential presence of sub-groups. Results Except for general ‘noisier’ (less consistent) decisions in TS, we showed no specific risk-taking behaviour in TS or any relation with tics severity or antipsychotic medication. However, the presence of comorbidities was associated with distortion of decision-making. Specifically, TS with obsessive–compulsive disorder comorbidity was associated with a higher risk-taking profile to increase gain and a higher risk-averse profile to decrease loss. TS with attention-deficit hyperactivity disorder comorbidity was associated with risk-seeking in the ambiguity context to reduce a potential loss. Conclusions Impaired valuation of risk and ambiguity was not related to TS per se. Our findings are important for clinical practice: the involvement of individuals with TS in real-life risky situations may actually rather result from other factors such as psychiatric comorbidities.
