Autism affects information processing in the brain by altering how nerve cells and their synapses connect and organize; how this occurs is not well understood.[3] Autism is usually caused by genetic transfer‚ and in rare cases‚ autism is strongly associated with agents that cause birth defects.[6] Controversies surround

Autism Spectrum Disorder (ASD) refers to a group of neural development disorders characterized by patterns of demeanor. Parents reactions towards the news of a child diagnosed with Autism are different in every family. This news can either make or break a family. These families have to mainly focus on how they will cope and how drastically their lifestyles will change. Financially‚ Autistic families have the most difficulty raising a child. Sometimes‚ one of the parents quit their job to stay home

Genes are codes for certain function that are found in DNA. The combination of genes is what makes each individual unique. MCADD is a genetic disorder‚ caused by a mutation or damage to the gene‚ ACADM‚ that codes for the enzyme‚ medium chain acyl CoA dehydrogenase. This results in the enzyme being absent or existing in minimal quantities. An enzyme increases the rate of a chemical reaction. Our body needs many enzymes in order to make the materials needed for our bodies to function and be healthy

History of Autism Doctors have come a long way since 1908‚ when the word autism was first used. Here’s a look at the history of autism spectrum disorder. By Virginia Sole-Smith You might think of autism as a new problem because it has become so much more prevalent in recent years. But it’s actually been on the books for more than 70 years--and our thinking about the condition has changed dramatically during that time. Here are the key events in autism history. 1908: The word autism is used to describe

Most diagnoses of autism are usually never the same‚ even though‚ the symptoms are generally similar. Autism must not be confused with childhood schizophrenia or mental retardation
