Importantly, motor skill deficits did not significantly affect performance on the Carter Neurocognitive Assessment.
Forty-two children with holoprosencephaly were examined to determine the association of deep gray nuclei abnormalities with cognitive abilities and the effect of motor skill deficits on cognitive performance.
Indeed, recent studies of brain metabolism in adults with concussion history have found concurrent motor skill deficits and primary motor cortex metabolism abnormalities related to deficits in motor learning [ 32].
In contrast, individuals with depressive episodes in childhood/adolescence showed elevated rates of a range of childhood risk factors, including perinatal insults, parental psychopathology, motor skill deficits and caretaker instability.
However, these studies on bullying and motor skills have been limited by small sample sizes (Bejerot et al., 2011; Piek, Barrett, Allen, Jones, & Louise, 2005), pilot study settings (Bejerot & Humble, 2007) or addressed severe motor skills deficits in clinical populations (Bejerot & Humble, 2013; Lingam et al., 2012; Piek et al., 2005).
Individuals with TS and their family members frequently exhibit comorbid difficulties such as obsessions and compulsions (including full-blown OCD), which may reflect alternative manifestations of the genetic factors; ADHD; uneven neuropsychological profile (e.g., visual-motor integration and fine-motor skill deficits); and vulnerability to anxiety and depression are also common [ 4- 8].
Robbins was born with fine and gross motor-skill deficits.
Because of their motor-skills deficits, it falls upon Tarah to show her older brothers how to do chores, though she suspects that sometimes they just want her to demonstrate so that they don't have to do it themselves.
Ms. Reitzes, who runs the youth center at the 92nd Street Y, said many educators were embracing blocks as an antidote to fine-motor-skill deficits and difficulty with unstructured activity, problems that they blame on too much time in front of screens and overly academic preschools.
We hypothesized, that NF1 patients show an impairment in motor skill acquisition, and that these deficits will be paralleled by impaired modulation of inhibitory neurotransmission in the M1.
Other groups have questioned the reliability of this finding, instead describing deficits in motor skill learning [ 31], abnormal synaptic plasticity in striatal and cerebellar neural circuits [ 31] and differences in auditory brainstem responses [ 32] in heterozygous pups.
