The month of April has been deemed National Autism Awareness Month in an effort to raise awareness about autism spectrum disorder, a group of complex disorders of brain development that affect over 3 million individuals in the U.S. alone, and tens of millions worldwide. Although so many are affected by autism every day, there is still so much that many people don't know about. Here are eight facts to keep you informed as Autism Awareness Month comes to a close:

1. One in 68 children will be diagnosed with autism.

In fact, boys are four times more likely to be diagnosed with autism spectrum disorder. Their statistic is only one out of 42. Unfortunately, that number is increasing every year.

2. Autism is a developmental disability of the brain, and usually appears before the age of three.

Social interaction, communication skills, and cognitive function are all affected by this, along with verbal and non-verbal communication skills, which can become difficult as well.

3. Other medical conditions can be a factor.

Usually, allergies, asthma, epilepsy and sensory issues, along with many other possible medical conditions, persist in those with autism.

4. The risk of mortality is twice as high.

Although autism does not directly affect life expectancy, accidents such as drowning are a much higher risk for those who have autism.

5. According to the National Autism Association, autism is the fastest growing developmental disorder, yet the most underfunded.

Families are greatly impacted when it comes to the expenses associated with a child who has autism. They must constantly have care and special treatment, but most shockingly, health insurance does not cover many of the costs associated with doctor's visits and other things necessary for their child.

6. There is a wide spectrum.

Autism has a wide range of effects on symptoms, skills, and development levels that impact each individual differently. In some cases, it can be hard to detect that a person has autism; in others, it can become more serious and result in the need of constant care.

7. The earlier autism is detected, the better.

Autism can usually be detected at an early age if parents look out for possible signs and symptoms. Trouble communicating, lack of focus, repetitive behavior or failure to respond to certain things are just a few of many symptoms that can be spotted when your child is just a few months old.

8. Autism is treatable.

The importance of spreading awareness about this ever growing neurological disorder cannot be captured in only one month. Everyday, organizations like Autism Speaks and the National Autism Association look to further research and help families whose lives are turned upside down by autism spectrum disorder.
