Their behaviour falls into two or three core clusters of symptoms, impaired sustained attention and hyperactivity/impulsiveness that develops gradually in familiar situations, with impairment manifesting before age 7 [ 3, 5].
Lahera et al. (2008) showed impaired sustained attention and executive functions in such patients.
At 9 1/2 years of age, E-CPT testing clearly indicated that the PCB-related impulsive responding was due to impaired response inhibition and not impaired sustained attention.
The 3.0 mg/kg exposed males committed significantly more omission errors than control males during the final 1/3 of each testing session, specifically on trials that followed an error, which implicates impaired sustained attention and increased reactivity to committing an error.
Laser-ablation of these cells impairs sustained spicule intromission and consequently, the ability to ejaculate.
Conversely, depletion of cortical noradrenaline impairs sustained attentional performance in the 5-CSRTT in rats (Carli et al., 1983).
Numerous studies suggest that patients with severe psychiatric disorders have impaired sustained attention [ 7] and memory [ 8- 10].
By contrast, deletion of Stim2 alone has no effect on the peak of Ca2+ influx but significantly impairs sustained SOCE (Oh-Hora et al, 2008).
He recently underwent formal neuropsychological evaluation that demonstrated moderately impaired sustained attention, mildly impaired delayed recall on a word list, and moderately impaired executive functioning as measured by a card-sorting test.
