“…Of note, two previous studies (Scherr et al 2010; Lilienthal & Weatherly, 2013) focusing on healthy female college students at risk for AN (according to self-report) also did not find differences in delay discounting of monetary gains between at-risk and non-risk students. Temporal delay discounting has been investigated in a multiplicity of other psychiatric disorders.…”

Increased cognitive control, which has been suggested as a key characteristic of AN, does not seem to extend the capacity to wait for delayed monetary rewards. Differences between our study and the only previous study reporting decreased delay discounting in adult AN patients may be explained by the different age range and chronicity of acute patients, but the fact that weight recovery was not associated with changes in discount rates suggests that discounting behavior is not a trait marker in AN. Future studies using paradigms with disorder-specific stimuli may help to clarify the role of delay discounting in AN.

“…Dysfunction of cognitive control often leads to impulsive behavior, which is symptomatic of disorders such as schizophrenia (Ouzir, 2013), bipolar disorder (Fortgang et al 2016), drug abuse and addiction (Jentsch & Taylor 1999; Crews & Boettiger, 2009; Washio et al 2011), pathological gambling (Dixon et al 2006), and eating disorders (Manwaring et al 2011; Lilienthal & Weatherly 2013). …”

Dissociable frontostriatal white matter connectivity underlies reward and motor impulsivity

Dysfunction of cognitive control often leads to impulsive decision-making in clinical and healthy populations. Some research suggests that a generalized cognitive control mechanism underlies the ability to modulate various types of impulsive behavior, while other evidence suggests different forms of impulsivity are dissociable, and rely on distinct neural circuitry. Past research consistently implicates several brain regions, such as the striatum and portions of the prefrontal cortex, in impulsive behavior. However the ventral and dorsal striatum are distinct in regards to function and connectivity. Nascent evidence points to the importance of frontostriatal white matter connectivity in impulsivity, yet it remains unclear whether particular tracts relate to different control behaviors. Here we used probabilistic tractography of diffusion imaging data to relate ventral and dorsal frontostriatal connectivity to reward and motor impulsivity measures. We found a double dissociation such that individual differences in white matter connectivity between the ventral striatum and the ventromedial prefrontal cortex and dorsolateral prefrontal cortex was associated with reward impulsivity, as measured by delay discounting, whereas connectivity between dorsal striatum and supplementary motor area was associated with motor impulsivity, but not vice versa. Our findings suggest that (a) structural connectivity can is associated with a large amount of behavioral variation; (b) different types of impulsivity are driven by dissociable frontostriatal neural circuitry.
