This work was aimed at obtaining a profile of neuropsychological impairments in young Spanish participants with anorexia nervosa (AN) to demonstrate that right-hemisphere and frontal capacity impairments are present not only in the acute phase but also after weight recovery in a Spanish sample compared with a healthy control group. Twelve patients with AN in the acute phase (body mass index [BMI] < 17) were compared both to 16 healthy control subjects and 12 weight-recovered AN participants (BMI ! 17) matched by age, IQ, and educational level by utilizing a wide neuropsychological battery. Differences were found between AN groups only for long-term verbal memory, which worsens as BMI increases. Among participants with AN as a group, results showed differences in speed of information processing, working memory, visual memory, and inhibition, unrelated to attentional capabilities. We cannot support the hypothesis of a specific right cerebral dysfunction in patients with AN. A general cognitive dysfunction, primarily in information processing, working memory, visual and verbal memory, as well as frontal impairments such as impulsivity and poor behavioral control, appeared unrelated to BMI. We support previous works affirming that neuropsychological impairments in AN are not a consequence of the illness but a risk factor for it to develop.
Twenty-five early-onset relapsing-remitting multiple sclerosis patients (12 women and 13 men) with mild disability were compared with 25 matched controls in a dichotic listening (DL) test under nonforced and forced attentional-shift conditions. Patients showed left ear impairment and no left ear advantage in the forced-left condition. Four corpus callosum (CC) regions were measured in patients on a midsaggital magnetic resonance imaging scan. The right ear score was negatively correlated whereas the left ear score was positively correlated with CC regions (significant only for the nonforced condition). Moreover, in men, the correlations with DL scores were linked mainly to the splenium and posterior isthmus, and in women, they were stronger for anterior isthmus and posterior body. An inverse correlation between months of disease evolution and CC area was found only in women.
The present work aimed to replicate Hugdahl and Hammar's (1997) study on the reliability of dichotic listening under divided or focused attention conditions. With the same consonant-vowel syllable dichotic listening procedure, 16 subjects were tested twice, 2 weeks apart. The design included a condition without attentional instructions (nonforced) and two conditions with the instruction to attend either to the right- or the left-ear input. The results showed a significant correlation coefficient of.82 for the standard nonforced condition, indicating temporal stability for the ear advantages. There were also high correlation coefficients for the focused attention conditions (.77 and.76), although the subjects performed the attentional instructions more accurately in session two.
This work supports previous findings questioning the efficacy of CT or CS for AD. Moving toward CFIs focused on relevant goals and including measures related to the skills, abilities or activities that are the focus of the intervention is encouraged. (PsycINFO Database Record
