J’ai étudié pendant 35 ans la neurotransmission mettant en jeu la dopamine. J’ai aussi écrit plusieurs articles, y compris dans des revues internationales, concernant le trouble déficitaire de l’attention avec hyperactivité (TDAH) et plus généralement la psychiatrie.

The one-year-old boy could not sleep longer than 2 hours – day or night. After 20 months spent in exhaustion and sleepless nights, his mom decided to eliminate wheat and dairy products from his diet. Withing 3 days Ethan slept peacefully all night long. Certain dietary changes improve the connection between the gut and the brain. In children with autism, sensorimotor regions of the brain become overconnected. In early childhood, the neurons inside children's developing brains form connections between various regions of brain "real estate.

" As described in a paper published last week in the journal Biological Psychiatry, cognitive neuroscientists at San Diego State University found that in children and adolescents with autism spectrum disorder, the connections between the cerebral cortex and the cerebellum appear to be overdeveloped in sensorimotor regions of the brain. This overdevelopment appears to muscle in on brain "real estate" that in typically developing children is more densely occupied by connections that serve higher cognitive functioning.

The study represents the first ever systematic look at connections between the entire cerebral cortex and the cerebellum using fMRI brain imaging, and its findings provide another piece in the puzzle that could one day lead researchers to develop a reliable brain-based test for identifying autism. Back to the cerebellum Over- and underconnected. Researchers find synaptic link to autism. Columbia neurobiologists led by David Sulzer have made a discovery that may help explain why people with autism are prone to epilepsy and often oversensitive to noise and social experiences.

The scientists have found that autistic young people have an overabundance of synapses in some parts of their brains, and that this excess is the result of the brain having failed to weed out unnecessary synapses through a process called “pruning.” Scientists have long known that synapses — the connections that neurons use to send and receive signals — grow at a furious pace in childhood and must be periodically thinned out, but the Columbia study is the first to show that unchecked synaptic growth is associated with autism. “From early childhood to adolescence, synapses are pruned,” says Sulzer, who is a professor of psychiatry, neurology, and pharmacology. “In other words, you start out, say, at age three, with about twice the density of synapses than you have at the age of fifteen. Autisme: "On oublie que les enfants autistes deviennent des adultes" - L'Express Styles. J'ai été officiellement diagnostiquée Asperger le 24 décembre 2014.

J'ai 33 ans. Si mon cas est passé inaperçu tout ce temps, c'est parce que a priori, mon profil ne correspond pas à la définition classique de l'autisme. Je suis professeur de lettres, j'ai un mari, deux enfants en bas âge. J'ai eu ce qu'on appelle un parcours scolaire "brillant". Aucun trouble visible n'a inquiété mon entourage durant la petite enfance. C'est à l'entrée au collège que la cassure s'est produite. Autisme: “On oublie que les enfants autistes deviennent des adultes” (L’Express, avril 2015) Autism-linked DNA deletion may derail brain development — Hot hubs: Researchers have mapped the binding partners of proteins encoded by the 16p11.2 region (red).

Missing a swath of chromosome 16 with strong ties to autism disrupts proteins that are crucial for early brain development, according to a study published 18 February in Neuron1. The findings open the door to targeted interventions, says lead researcher Lilia Iakoucheva, assistant professor of psychiatry at the University of California, San Diego. “Getting to this more specific pathway is very valuable,” she says. About 1 percent of children with autism have a deletion or duplication of 16p11.2 — a 600-kilobase stretch of DNA that includes 29 genes. This region also affects head size: People with a deletion of the region have unusually large heads, whereas those with a duplication have unusually small heads.

To tease out the role of genes in the 16p11.2 region, the researchers mapped where and when these genes are expressed in the brain.
