There are lots of frightening rumors about what causes autism, a mysterious brain disorder, in children. Usp9x is a master-stabilizer of many key proteins essential for brain development and learning. Autism has no one single cause, both in terms of genes and the brain. 12. PKU. The psychology and biology of a complex developmental condition Autism is diagnosed when a child or adult has abnormalities in a "triad" of behavioural domains: social development, communication, and repetitive behaviour/obsessive interests.1,2 Autism can occur at any point on the IQ continuum, and IQ is a strong predictor of outcome.3 Autism is also invariably accompanied by language . The brain develops differently in autistic children compared with typically developing children. It is suggested to involve both genetic susceptibility and environmental factors including in the latter environmental toxins. Genetic factors seem to be important. Because the disorder is so complex and no two people with autism are exactly alike, there are probably many causes for autism. Flawed brain development is also a top theory in the causes of autism. There is a cure for autism spectrum .

Some children with autism grow up to lead normal or near-normal lives. There is often nothing about how people with ASD look that sets them apart from other people, but people with ASD may communicate, interact, behave, and learn in ways that are different from most other people. Most people accept that it is caused by abnormalities in the brain. Every time a child . A new study offers a fresh perspective on how autism works in the brain. Autism: Brain Disorder or Body-Based Biological Illness?

Recent findings suggest that the many different symptoms may actually indicate many different causes-- and thus many different "autisms."A massive study now underway at UC Davis's M.I.N.D. INTRODUCTION.

Possible causes. People with autism spectrum disorder (ASD) suffer from a profound social disability. In the developing brain, connections between and within brain regions are still being formed.
While many different combinations of genetic traits can cause autism, brains affected by autism share a pattern of ramped-up immune responses and related inflammation, an analysis of data from autopsied human brains reveals. Nobody knows what causes autism, a condition that varies so widely in severity that some people on the spectrum achieve enviable fame and success while others require lifelong assistance due to .

Certain known genetic disorders are associated with an increased risk for autism, including Fragile X syndrome (which causes intellectual disability) and tuberous sclerosis (which causes benign tumors to grow in the brain and other vital organs) — each of which results from a mutation in a single, but different, gene.

Colloquially speaking, brain fog refers to thinking that is sluggish or fuzzy. Cerebral dysgenesis (abnormal brain development) Rett syndrome (caused by a single gene mutation) Metabolic or biochemical defects; Brain studies have shown that individuals with autism have brain structure abnormalities. Institute is in the process of separating out different autistic .

A consideration of autism as an evolutionarily recent disorder also suggests that disruption of evolutionarily new parts of the brain may relate to autism. Autism spectrum disorder has three main types or features; social interaction problems, verbal and nonverbal communication impairment, and repetitive behavioral problems. Dec 15, 2014.

It is notable that severe mutations in ankyrin-G are also known to cause intellectual disability and autism. _____4. The role of genetics in causing autism is one of the most prominent and well-researched theories. Additional Resources for Autism. There is strong evidence to suggest that autism can be caused by a variety of physical factors, all of which affect brain development - it is not due to emotional deprivation or the way a person has been brought up.

Autism is not a medical condition with treatments or a "cure".

Sometimes, though, these connections don't form in the normal way, which can produce lasting changes in behaviour. The brain develops differently in autistic children compared with typically developing children.

Although it is diagnosed based on the presence of two core behaviors — restricted interests and repetitive behaviors, as well as difficulties with social interactions and communication — those traits are thought to arise because of alterations in how different parts of the brain form and connect to one another. Kids with autism spectrum disorders are mean and do not like to be hugged. Over a hundred different genes have been associated with the risk for autism. Most researchers believe that ASDs have a variety of causes.They could perhaps all affect the same brain systems,or they could impede development through disruption of the different abilities necessary for social and communicative development. Brain development and autism. _____2. When the cause of autism is a chromosome abnormality or a single-gene alteration, the risk that other brothers and sisters will also have autism depends on the specific genetic cause. It is probably due to a variety of factors, including genetic and environmental influences.

Scientists at the University of California, San Diego School of Medicine have found that mutations that cause autism in children are connected to a pathway that regulates brain development. By late childhood, the researchers found that spine density had dropped by about half in the healthy brains, but by only 16 per cent in the brains of autistic individuals. Symptoms, the authors say, may be linked to persistent connections in the brain. Parents often notice signs during the first three years of their child's life. In the last couple of months alone, air pollution, gluten sensitivity .

In young children, the brain is developing all the time. There are various factors that increase the risk of autism.

Autism is a behavioral/developmental disorder characterized clinically by delays and qualitative differences in communication and social interaction as well as repetitive behaviors and restricted interests. National Institute of Neurological Disorders and Stroke. Autism spectrum disorder is a neurodevelopmental disorder of unknown aetiology. Exploring the environmental contribution Philip J. Landrigan Introduction Autism is a complex, serious, biologically based disorder of brain development first described in 1943 by Kanner [1]. Social deficits, abnormalities in communication, repetitive behaviors, and cognitive inflexibility are the characteristic features [2]. The disorder also includes limited and repetitive patterns of behavior. People with ASD are born with it and their problems usually begin in the first couple of years of life. However, they account for only a small fraction of cases, and do not easily explain key clinical and epidemiological features.
