The Classification of Autism, Asperger's Syndrome, and Pervasive Developmental Disorder

Change in Autism Symptoms and Maladaptive Behaviors in Adolescents and Adults with an Autism Spectrum Disorder

“…Furthermore, based on past research (e.g., Howlin et al, 2004), we hypothesized that individuals without mental retardation would show greater declines in autism symptoms and maladaptive behaviors between Time 1 and Time 4 than those who have MR. Finally, again based on past research (e.g., Lord & Bailey, 2002;Szatmari, 2000), we hypothesized that those with better language abilities would show greater declines in autism symptoms and maladaptive behaviors between Time 1 and Time 4. Prior findings with respect to an association between gender and the likelihood of change are mixed and do not permit specific predictions.…”

Investigation of Neuroanatomical Differences Between Autism and AspergerSyndrome

“…2,6,7 Because persons with HFA also have IQs of at least 70, and the DSM-IV does not require a history of language delay for a diagnosis of autism, this creates a diagnostic overlap between HFA and ASP, resulting in many individuals with ASP who meet DSM-IV criteria for autism. 4,8 As a result, many studies comparing HFA and ASP distinguish these 2 conditions according to history of phrase language development (HFA at 36 months or older, and ASP at younger than 36 months). [9][10][11][12][13] Owing to the diagnostic similarities between HFA and ASP, a debate is growing about the validity of ASP as a disorder distinctly different from autism.…”

Síndrome de Asperger e TOC: comorbidade ou unidade?

“…Sua prevalência é difícil de ser avaliada, visto que existem poucos estudos neste sentido, com resultados que variam de 2 a 56 casos por 10.000 habitantes (Suzuki e Saito, 2007). Tem se falado cada vez mais sobre os transtornos que compõem o "espectro autista", e desde que a(o) síndrome/transtorno de Asperger foi reconhecida(o) como uma entidade nosológica a parte, pela Organização Mundial de Saúde (1992) e pela Associação Americana de Psiquiatria (1994), tem surgido discussões acerca de suas diretrizes e critérios diagnósticos (Szatmari, 2000). Além de compartilhar características comuns a outros transtornos do "espectro autista", alguns de seus principais sintomas se sobrepõem a outras condições, tais como transtorno de déficit de atenção e hiperatividade (TDAH) e transtorno obsessivo-compulsivo (TOC), dificultando o estabelecimento de uma fronteira entre o que seria uma manifestação da própria síndrome ou o que seria uma comorbidade (Blacher et al, 2003;Gillberg, 2002).…”
