Although several resting-state functional magnetic resonance imaging (rsfMRI) studies have extensively examined long-range (or distant) connectivity in the adult ASD brain, short-range (or local) connectivity has been investigated in less depth. Furthermore, the possible relationship between functional connectivity and brain activity level during the resting state remains unclear.

Clinical characterization of adults with Asperger's syndrome assessed by self-report questionnaires based on depression, anxiety, and personality / Chieko KANAI in Research in Autism Spectrum Disorders, 5-4 (October-December 2011)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 5-4 (October-December 2011) . - p.1451-1458 Titre : Clinical characterization of adults with Asperger's syndrome assessed by self-report questionnaires based on depression, anxiety, and personality Type de document : Texte imprimé et/ou numérique Auteurs : Chieko KANAI, Auteur ; Akira IWANAMI, Auteur ; Ryuichiro HASHIMORO, Auteur ; Haruhisa OTA, Auteur ; Masayuki TANI, Auteur ; Takashi YAMADA, Auteur ; Nobumasa KATO, Auteur Année de publication : 2011 Article en page(s) : p.1451-1458 Langues : Anglais (eng) Mots-clés : Asperger's syndrome  Clinical characterization  Autism-Spectrum Quotient (AQ)  Hospital Anxiety and Depression Scale (HADS)  Liebowitz Social Anxiety Scale (L-SAS)  NEO Five-Factor Inventory (NEO-FFI) Index. décimale : PER Périodiques Résumé : Diagnosing Asperger's syndrome (AS) in adults is difficult and efficient indicators for a precise diagnosis are important in the clinical setting. We examined the clinical characteristics of AS in 129 adults (median age, 32.0 years [range, 19–57]; 102 men and 27 women; AS group (n = 64; median age, 32.0 years [range, 19–50]; 50 men and 14 women), control group (n = 65; median age, 32.0 years [range, 19–57]; 52 men and 13 women) through administration of the Japanese version of the Autism-Spectrum Quotient (AQ) and the Japanese version of the Hospital Anxiety and Depression Scale (HADS), the Liebowitz Social Anxiety Scale (L-SAS), and the NEO Five-Factor Inventory (NEO-FFI). AQ, HADS, and L-SAS scores, and the ‘Neuroticism’ scores of the NEO-FFI were significantly higher in adults with AS than in controls. The ‘Extraversion’, ‘Agreeableness’, and ‘Conscientiousness’ scores of the NEO-FFI were significantly lower in adults with AS than in controls. Total score of the AQ correlated with the ‘Anxiety’ subscale score of the HADS and the ‘Extraversion’, ‘Openness’, and ‘Conscientiousness’ subscale scores of the NEO-FFI in adults with AS, but not in controls. The findings demonstrated that the AQ and other scales could be used to elucidate the clinical characteristics of AS in adults.

We examined cognitive profiles of adults with no intellectual disability (IQ > 70), and in adults with Asperger's disorder (AS; n = 47), high-functioning autism (HFA; n = 24), and pervasive developmental disorder not otherwise specified (PDDNOS; n = 51) using the WAIS-III. Verbal Intelligence (VIQ)–Performance Intelligence (PIQ) differences were detected between the three groups. Full Intelligence (FIQ) and VIQ scores were significantly higher in AS than in HFA and PDDNOS. Vocabulary, Information, and Comprehension subtest scores in the Verbal Comprehension index were significantly higher in AS than in the other subgroups, while Digit-Symbol Coding and Symbol Search subtest scores in the Processing Speed index were significantly lower in HFA. The findings demonstrated cognitive profiles characteristic of adults with high-functioning PDD.

We compared the frequency of mental and behavioral symptoms, motor abnormality, and life history between adults with AS and those with no mental disorders but with disturbance of social functions and communication skills (ND) from our outpatient clinic. Participants with AS (n = 99) as compared with ND subjects (n = 63) showed significant higher rate of depressive mood, anxiety, unstable emotion, mood swings, oversensitivity to normal situation obsessive compulsive symptoms, persecutory idea, loss of energy, insomnia carelessness, restlessness, confusion in new environments, episodic agitation, inflexible adherence, egocentric behavior, self harm, circumscribed interest, poor lifestyle habits, non-athleticism, clumsiness, bulling at school, school non-attendance, social withdrawal, and lack of friendships. In AS, emotional instability and confusion in new environments might lead to social isolation. The findings demonstrated that individuals with AS experience greater social isolation and distress, as well as a wider range of mental and behavioral symptoms and disturbances of motor skills as compared to healthy subjects with disturbances of social functions and communication skills. These factors are interrelated and may be used as supplementary methods for differential diagnosis of AS from other conditions.

Standardization of the Japanese version of the Glasgow Sensory Questionnaire (GSQ) / Yuko TAKAYAMA in Research in Autism Spectrum Disorders, 8-4 (April 2014)

However, limited measures that assess these problems in adults with ASD have been developed till date, particularly in Japan. Robertson and Simmons (2012) developed a self-rating scale to investigate sensory sensitivity: the Glasgow Sensory Questionnaire (GSQ). In the present study, we developed a Japanese version of GSQ and investigated sensory abnormalities in adults with ASD. We compared results of the Japanese version of GSQ in adults between an ASD group (n = 64) and a control group (n = 70). In addition, we also administered these individuals with the autism spectrum quotient (AQ), which is a questionnaire for assessing autistic traits. The Japanese version of GSQ scores was significantly higher in the ASD group than that in the control group. The total GSQ score and each sensory subscale showed a positive correlation with AQ in the total study sample. These results indicate that individuals with pronounced autistic traits have more frequent and extreme sensory processing problems compared with that in individuals with less pronounced autistic traits. We also assessed validity of the new test. Cronbach's ? of the questionnaire was calculated, and its high value indicates that the Japanese version of GSQ has high reliability.
