“…Only a few reports have described what poor performance in PA implies. In psychiatric disorders, PA and explanation of the story have been considered to be associated with social cognition [2,30]. However, PA requires more complex factors than social cognition.…”

Writing errors as a result of frontal dysfunction in Japanese patients with amyotrophic lateral sclerosis

et al. 2010

Loss of communication is a critical problem for advanced amyotrophic lateral sclerosis (ALS) patients. This loss of communication is mainly caused by severe dysarthria and disability of the dominant hand. However, reports show that about 50% of ALS patients have mild cognitive dysfunction, and there are a considerable number of case reports on Japanese ALS patients with agraphia. To clarify writing disabilities in non-demented ALS patients, eighteen non-demented ALS patients and 16 controls without neurological disorders were examined for frontal cognitive function and writing ability. To assess writing errors statistically, we scored them on their composition ability with the original writing error index (WEI). The ALS and control groups did not differ significantly with regard to age, years of education, or general cognitive level. Two patients could not write a letter because of disability of the dominant hand. The WEI and results of picture arrangement tests indicated significant impairment in the ALS patients. Auditory comprehension (Western Aphasia Battery; WAB IIC) and kanji dictation also showed mild impairment. Patients' writing errors consisted of both syntactic and letter-writing mistakes. Omission, substitution, displacement, and inappropriate placement of the phonic marks of kana were observed; these features have often been reported in Japanese patients with agraphia resulted from a frontal lobe lesion. The most frequent type of error was an omission of kana, the next most common was a missing subject. Writing errors might be a specific deficit for some non-demented ALS patients.

“…Although social cognition requires general cognitive capacities and there may be some functional overlap of brain areas underlying social cognition and other more general cognitive processes, previous evidence have shown that aforementioned cognitive domains are distinct from one another and that social cognitive impairments in schizophrenia are separable from the general cognitive ability (Allen et al, 2007;Sergi et al, 2007). Neuroimaging and lesion studies have shown that social tasks activate specific brain areas that can be distinguished from those activated by non-social tasks, for example superior temporal sulcus, medial prefrontal cortex (Adolphs, 2001;Harris et al, 2005;Mitchell et al, 2004), amygdala, fusiform gyrus and insular regions (Bar-On R et al, 2003).…”

AbstractAlterations in general intellectual ability and social cognition in schizophrenia are core features of the disorder, evident at the illness' onset and persistent throughout its course.However, previous studies examining cognitive alterations in siblings discordant for schizophrenia yielded inconsistent results. Present study aimed to investigate the nature of the association between facial emotion recognition and general IQ by applying genetically sensitive cross-trait cross-sibling design. Participants (total n=158; patients, unaffected siblings, controls)were assessed using the Benton Facial Recognition Test, the Degraded Facial Affect Recognition

“…The research to date has focused almost exclusively on populations known to have social deficits (e.g., schizophrenia, attention deficit hyperactivity disorder, and autism spectrum disorders) and not on very high functioning populations such as aviators. Moreover, prior research has indicated the importance of relative deficits in Comprehension scores as compared to a subject's general intelligence in the relationship between the Comprehension subtest and social functioning [27,28]. Lastly, the Wechsler tests of intellectual ability have been used almost exclusively in these previous studies.…”
