Autism Spectrum

Wednesday, June 23rd, 2010

In addition to categorizing subdivisions of autism in several, are clearly delimited from each species are the

  • Autism spectrum or autism spectrum disorder (ASD). This is a concept of a smooth transition between the different forms, one in particular in the growing English-speaking point of view of such a continuum of different forms. Represented approximately by Tony Attwood, who justified his view with the possibility of transitions in individual cases. For example there are autistic people that meet the diagnostic criteria of Asperger’s syndrome, the abnormalities in early childhood, however, corresponded to the diagnosis of Kanner’s syndrome. Moreover, it is doubtful whether one based on theoretical models of intelligence IQ measurement or an arbitrary maximum age limit for the language used for the distinction.

Published a study by a significant proportion of ICD-10 were diagnosed with infantile autism or atypical autism diagnosed according to people with Asperger Gillberg diagnostic criteria.

Subclinical Forms of Autism

Monday, June 21st, 2010

  • A clinical autism spectrum diagnosis by doctors or psychologists usually placed under the condition that a person suffers in several areas of life. A person may well be autistic, but because of their situation in life, talent and / or support of education, training, employers, friends, partners or other forms of support to cope well enough to get no clinical diagnosis. In this case, such a person may receive a diagnosis, if, after a possible loss of aid leads to an anomaly, so that doctors and therapists can justify a clinical diagnosis.
  • The question of whether it is in autism or autism spectrum disorders a category or a dimension is unclear. There is literature on subclinical forms of autism, a chapter about “Autistic Echos” in the book “The shadow syndrome: Neurobiology and mild forms of mental disorders”. In research, the concept of a ‘Broad Autism Phenotypes examines’, such as autistic traits from parents of autistic children.
  • Some other official (ICD-10/DSM-IV) and unofficial (not in ICD-10/DSM-IV) diagnoses are examined in relation to autism, such as Hyperlexia, nonverbal learning disability, dyspraxia, sensory integration disorder or linguistic-pragmatic disorder . The issue of these as a separate diagnosis, or rather as part of a broader autism spectrum may be seen is unclear.

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.

Diagnostic Criteria of Autism

Wednesday, June 2nd, 2010

Autism (from Gr αὐτός “itself) is classified by the World Health Organization as a pervasive developmental disorder, is by doctors, researchers, families and autistic self-described as a congenital, incurable perception and information processing disorder of the brain that are already in early childhood noticeable. Other researchers  and autistic people describe autism as a different mode of information congenital, which is indicated by weakness in social interaction and communication, and by stereotyped behavior patterns and strengths in perception, attention, memory and intelligence.

In the current diagnostic criteria, it is a distinction between infantile autism (Kanner syndrome) and Asperger’s syndrome, which often becomes apparent only after the third year of life. Many doctors believe, however, has become an autism spectrum (autism spectrum disorder), the different severity knows.

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…)

At 7 months infants and distinguish emotions through voice

Wednesday, May 5th, 2010

The brains of babies at 7 months shows a sensitivity to the human voice and the emotions communicated through the voice that is very similar to that observed in the brains of adults, according to a study by the University of London in United Kingdom published in the journal Neuron.

The study proves the origins of voice processing in the human brain and could provide information on neurodevelopmental disorders such as autism.

Scientists at the Center for Brain and Cognitive Development at the University of London, led by Tobias Grossmann, conducted their study in the laboratory of Angela D. Friederici Max Planck Institute in Cognitive Science and Human Brain in Germany. The researchers used near infrared spectroscopy to investigate when during development the regions of the temporal cortex became sensitive to the human voice. These specific cortical regions have had an important role in spoken language processing in adults.

Grossmann’s team found that children of seven months and not four months showed greater responses similar to those of adults in the temporal cortex as a result of the human voice compared with no vowel sounds, suggesting that sensitivity to voice emerges between 4 and 7 months of age. (more…)
