Autistic Disorder

  • The typical autism does not meet all diagnostic criteria of infantile autism and does not show until after the third year of life. As a subtype of autism but he is differential diagnosis for Asperger syndrome defined.
  • The Asperger Syndrome (obsolete even autistic psychopathy and schizoid disorder of childhood), especially with a date of her age-appropriate language (according to the ICD-10 and DSM-IV criteria for a diagnosis – after a while Gillberg & Gillberg delayed language development a possible diagnostic criterion represents) and a correct from a formal point of view of language. People with Asperger syndrome are often clumsy motor.

To form the circle of pervasive developmental disorders according to classification of the diagnostic manuals ICD-10 are in addition to autistic disorder (in the strict sense) but also the

  • Rett syndrome and Heller’s syndrome (disintegrative psychosis of childhood) that have similar symptoms, but differ in the course of autism. In Rett syndrome is now also a characteristic of this genetic alteration detected.

Hystory of Autism

Friday, June 11th, 2010

Leo Kanner (Lit: Kanner 1943) and Hans Asperger (ref: Asperger 1938) took the notion – independently – on and described a special kind of disorder you distinguish this people with schizophrenia to withdraw active in their affairs, of those who live from birth in a state of inner solitude. This expanded the meaning of the term “autism”.

Kanner took the term “autism” narrow, which corresponded broadly to the so-called infantile autism today (hence: Kanner’s syndrome). His view gained international recognition and became the basis for further autism research. The publications, however Asperger described “autism” were somewhat different and at first received little international. This was the one taking place simultaneously at the Second World War, partly because that Asperger published in German and it’s not translated into English texts for decades. Hans Asperger himself was called by him the syndrome described “autistic psychopathy”. The English psychologist Lorna Wing (Ref: Wing 1981) led her away in the 1980s and the name of an Asperger’s Syndrome. Only in the 1990s, Asperger’s international research reputation acquired in professional circles.

Autism Symptoms & Complaints

Saturday, June 5th, 2010

A small boy with autism and the exact line of toys, which he filed together. The symptoms and the individual forms of autism are varied, they misjudged by mild behavioral problems at the border of the low profile (such as “timidity”) to severe mental retardation range.

Allen autistic disabilities are impairments in social behavior in common: difficulty in speaking with others (for example due to monotonous prosody), been said to be interpreted correctly, use facial expressions and body language and understand.

Core symptoms associated with autistic disabilities is primarily the difficulty of communicating with other people (first and second diagnostic criterion). Alternatively, stereotyped or ritualization practices (third diagnostic criterion) explores all the core symptoms of autistic disabilities. Autistic people show fundamental differences from non-autistic people in the processing of sensory impressions and the way the discernment and intelligence. The differences in perception is explored as a core symptoms of autism.

The ‘mirror neurons’ of well-functioning autism

Friday, May 21st, 2010

When someone waves to them, our brain is capable of processing the gesture as something friendly and allows us to imitate. This is possible thanks to the mirror neuron system, a set of nerve cells, to date, it was thought that could go wrong in autistic spectrum disorders. However, a study published in ‘Neuron’ indicates that their normal activity in these patients.

The theory made sense. One of the most striking features of people with autism is their inability to imitation, empathy and understanding of the intent of the gestures of others. If mirror neurons are crucial for social interaction, it was logical to think that something is wrong with this brain system. In fact, some studies appeared to confirm the hypothesis.

But these works were overlooked something important. “No evaluated the selectivity of cortical activity in areas of particular movements mirror system,” says principal investigator, Ilan Dinstein, Department of Psychiatry at the University of New York (USA). This selectivity of movement is not simply the distinction that our brain makes every gesture, by storing a single neuronal response. (more…)
