Autism Research Blog: Translating Autism: Amygdala, autism and clinical impairment: Whe... - 0 views

  • The amygala serves a critical function in emotion recognition and processing, and thus it has been implicated in the neurophysiology of autism. For example, individuals with autism have been found to display atypical amygdala growth processes from childhood into adolescence (see for example Nacewiz et al., 2006. Archives of General Psychiatry, 63,12).
  • The Amygdale's bilateral biochemical functioning was obtained via magnetic resonance spectroscopy. Four metabolites were measured: N-acetyl aspartate (NAA), creatine/Phosphocreatine (Cre), choline (Cho), and myoinositol (ml).
  • The authors did not find any differences in the concentrations of any of the metabolites when comparing the HFA and the control groups
  • ...4 more annotations...
  • However, among the individuals with HFA, NAA was significantly associated with communication impairments, as measured by the ADI. In addition, Cre and NAA were associated with restrictive interests, and Cre alone was associated with social difficulties. The results therefore, indicate that those with the lowest concentrations of these metabolites tended to have more severe clinical symptoms as reported by the ADI.
  • The results of this study provide support for the need to conduct examinations that go beyond simple group comparisons.
  • key metabolites, while observed at normative levels, play a key role in the clinical presentation of the disorder.
  • presence of normative functioning in a particular domain or brain process (when compared to typical peers) does not necessarily indicate that such domain is not implicated in the phenomenology of the condition.

    Amygdala, autism and clinical impairment: When group comparisons are not enough. The results of this study provide support for the need to conduct examinations that go beyond simple group comparisons. In this case, the authors found no differences in any of the metabolites between the two groups, which could easily lead one to conclude that such metabolites may not play a role in autism. Yet, the results were strong in indicating that key metabolites, while observed at normative levels, play a key role in the clinical presentation of the disorder.

Eide Neurolearning Blog: Recess Essential for Improving Attention - 0 views

  • New research suggests that play and down time may be as important to a child’s academic experience as reading, science and math, and that regular recess, fitness or nature time can influence behavior, concentration and even grades.
  • Young children with sensory processing disorders are especially susceptible to behavioral and attention problems if they are not allowed to move and exercise throughout their day.

Eide Neurolearning Blog: Why Boys Need Alternatives with Reading and Writing - 0 views

  • If you give girls and boys language tasks, most girls will process the information in the same way (in a specialized language area)
  • help them with word storage and retrieval
  • But for boys, sensitivity to the modality of how words are presented means that an extra steps need to be taken to match words that are picked up by listening and words that are read on the printed page. No wonder dyslexia is much more common in boys - the separate system means that the sight and sound of words are learned as distinct processes.
  • ...4 more annotations...
  • As a result, verbal competence may be strong in one domain (oral speech for instance), but be weak in another (reading).
  • because boys require two areas and a matching of visual-auditory inputs, impairment in one system may cause the whole language coordination process to fail.
  • The visual-auditory gap may also be why some boys may need to read word-for-word outloud or to themselves (i.e. not silently read) in order to fully comprehend or remember the story.
  • Some careful consideration needs to made of instructional implications for boys given some of these new discoveries. Learning by listening and learning by reading are not synonymous; route-congruent factors(listening - oral presentation, reading - written response) may need to be considered when a learning gap or frank underachievement is seen, and an insistence on the availability of auditory-visual supports (reading along with books-on-tape, detailed handouts for lecture courses) should be a requirement of every classroom.

New Medication Ineffective for Autistic Symptoms - 0 views

  • What this means, sadly, is that the only drug on the market which has FDA approval to specifically treat autism is risperdal - a medication which, like many others, can have problemmatic side effects. In addition, risperdal is only useful for a relatively small number of people overall.

Childhood Disintegrative Disorder, Autism/PDD: Yale Child Study Center - 0 views

  • Childhood Disintegrative Disorder This rather rare condition was described many years before autism (Heller, 1908) but has only recently been 'officially' recognized.
  • The condition develops in children who have previously seemed perfectly normal. Typically language, interest in the social environment, and often toileting and self-care abilities are lost, and there may be a general loss of interest in the environment. The child usually comes to look very 'autistic', i.e., the clinical presentation (but not the history) is then typical of a child with autism.
  • A special educator in Vienna, Theodore Heller, proposed the term dementia infantilis to account for the condition.
  • ...3 more annotations...
  • in most cases after even very extensive testing no specific medical cause for the condition is found. As with autism, children who suffer from this condition are at increased risk for seizures.
  • evidence suggest that it arises as a result of some form of central nervous system pathology.
  • Childhood disintegrative disorder is perhaps 10 times less common than more strictly defined autism

Childhood disintegrative disorder: Causes - MayoClinic.com - 0 views

  • Causes There's no known cause of childhood disintegrative disorder, also known as Heller's syndrome. Most experts agree that there's likely a genetic basis for autism spectrum disorders. The theory is that an abnormal gene is switched on in the early stages of development, before birth, and that this gene affects other genes that coordinate a child's brain development.

Autism Research Blog: Translating Autism: Autism and Serotonin: Is MAOB the missing link? - 0 views

  •  
    Although dysregulation of serotonin has been associated with several psychiatric disorders, there is evidence suggesting that disruption in serotonin systems may be implicated in autism. Specifically, serotonin is a critical component of the regulation of the growth and maturation of key areas of the Brain.
