[Asperger's syndrome symptoms in children, adolescents and young adults].

Asperger's syndrome symptoms in children, adolescents and young adults. Asperger syndrome (AS) is a neurodevelopemental disorder which is classified into autism- spectrums disorders (ASDs). AS is characterized by significant difficulties in social interaction and nonverbal communication, stereotyped and restricted patterns of behaviour, activities and interests. There is no clinically significant delay in cognitive development nor general delay in language. However, there are specific abnormalities such as literal interpretations, miscomprehension of nuance, unusually pedantic and formal speech. Clinical aspects are very heterogeneous and vary depending on age and psychiatric comorbidities. Among the associated disorders, Attention Deficit Hyperactivity Disorder, mood and anxiety disorders are commonly found. To identify these conditions and offer appropriate treatment, elevated vigilance is needed in clinical practice.
