Editing Tourette syndrome (section)

=== Neuropsychological function ===
There are no major impairments in [[neuropsychological]] function among people with Tourette's,<!--the ref originally following the sentence after this was<ref name= Morand />--> but conditions that occur along with tics can cause variation in [[neurocognitive]] function. A better understanding of comorbid conditions is needed to untangle any neuropsychological differences between TS-only individuals and those with comorbid conditions.<ref name= Morand>{{cite journal |vauthors=Morand-Beaulieu S, Leclerc JB, Valois P, et al |title= A review of the neuropsychological dimensions of Tourette syndrome |journal=Brain Sci |volume=7 |issue=8 |page= 106 |date=August 2017 |pmid=28820427 |pmc=5575626 |doi=10.3390/brainsci7080106 |type= Review|doi-access= free }}</ref>

Only slight impairments are found in [[intelligence quotient|intellectual ability]], [[attentional control|attentional ability]], and [[nonverbal memory]]—but ADHD, other comorbid disorders, or tic severity could account for these differences. In contrast with earlier findings, [[visual motor integration]] and [[visuoconstructive]] skills are not found to be impaired, while comorbid conditions may have a small effect on [[motor skill]]s. Comorbid conditions and severity of tics may account for variable results in [[verbal fluency test|verbal fluency]], which can be slightly impaired. There might be slight impairment in [[social cognition]], but not in the ability to plan or make decisions.<ref name= Morand /> Children with TS-only do not show cognitive deficits.<!-- Hollis, Denckla --> They are faster than average for their age on timed tests of [[motor coordination]], and constant tic suppression may lead to an advantage in switching between tasks because of increased inhibitory control.<ref name= Hollis /><!--p. 6. --><ref name=Denckla /><!-- p. 20 -->

[[Learning disability|Learning disabilities]] may be present, but whether they are due to tics or comorbid conditions is controversial; older studies that reported higher rates of learning disability did not control well for the presence of comorbid conditions.{{sfnp|Pruitt|Packer|2013|pp=636–637}} There are often [[Dysgraphia|difficulties with handwriting]], and disabilities in written expression and math are reported in those with TS plus other conditions.{{sfnp|Pruitt|Packer|2013|pp=636–637}}
