Autism in America: Statistics, signs and symptoms
Over the years, the prevalence of autism has been on the rise. In fact, according to the Center for Disease Control (CDC), one in 59 children is diagnosed with an autism spectrum disorder (ASD). Of this population, males are four times more likely to be diagnosed with ASD than females, with higher prevalence rates in children born to older parents. Among those diagnosed with ASD, there's a strong comorbidity with other mental health disorders such as ADHD, anxiety, and depression.
While the rising rates of ASD have been widely believed to be attributed to vaccines in recent years, this theory has been debunked and the study that first made such claims has since been discredited. So just exactly why are autism rates growing over time? There are a variety of theories floating around, but one obvious factor could be the increasing statistics surrounding the age of parents over the years. According to statistics published from a recent Pew Research Center study, the average age of motherhood is 26 years of age. Back in 1970, this age was 21. There's also a higher rate of “geriatric pregnancies” as of late.
Causation factors aside, the rates of autism spectrum disorders are likely not going anywhere; demanding more education, understanding, and treatment options for Americans. But before we get into the variety of treatment options available, let's take a deeper look into ASD symptoms, and how these typically present in children today.
Autism Spectrum Disorder Symptoms and Challenges
The primary core symptoms of an autism spectrum disorder surround social challenges, communication challenges, and restricted—repetitive—behaviors. These symptoms begin during early childhood and may go unnoticed until ages 2-4. They also interfere with daily life functioning. While symptoms affect each person differently, those most associated with ASD can be broken down into three categories:
ASD Communication Challenges
It can be incredibly difficult for a person with ASD to communicate with others. Approximately 40 percent of those with ASD do not use speech at all. Of the remaining 60 percent, 25-30 percent will use some words by 12-18 months of age, but will then lose them. Others may not begin speaking until they are older. Those who are unable to communicate may be able to use some words, but they don't always make sense in sentence form. Others may repeat one word at a time to try to communicate. The verbal and non-verbal communication symptoms most commonly associated with ASD include:
Delayed speech or a lack of speech and language skills
Echolalia (saying words or phrases repetitively)
Mixing up pronouns such as “you” and “I”
Not cognizant of gestures such as pointing, waving, etc.
Answers questions with irrelevant responses
Inability to read facial expressions of others
Flat affect in tone of voice
Will not engage in play that incorporates pretending behavior (e.g. pretending to fly, or eat play food, etc.)
No understanding of things not meant to be literal, such as joking, sarcasm, etc.
Has difficulty making eye contact when interacting with others
ASD Social Interactions
Some of the more common symptoms associated with autism spectrum disorders surround social skills. Those who have ASD often face social difficulties that make it difficult for them to function in life. These could be as minor as shyness, or as major as an inability to understand social cues and mores. The most common symptoms that relate to social functioning a person with ASD may face are:
Prefers to play alone (may not be interested in others whatsoever)
Will not respond to own name at 12 months of age
Goal-oriented in all interactions (only talking to someone in order to achieve a task, etc.)
Avoiding physical touch
Failure to share interests with others
Odd facial expressions
Inability to understand feelings of others or self
During times of distress, others are not a comfort
Difficulty understanding boundaries, and personal space of others
ASD Behavioral Patterns
It's quite common for a person with ASD to exhibit unusual behaviors and interests. These often present as restricted, or repetitive behavioral patterns such as:
Lining things up in a row
Doing things in a specific order
Being fascinated with parts of objects
An extreme or obsessive interest in specific topics
Minor changes can be very upsetting
A strong focus on organization
Must have a consistent schedule that doesn't change
Will stare at lights or objects that spin
Repetitive motions with objects (clicking a pen, turning things on and off, etc.)
Repetitive body movements (spinning in circles, rocking, etc.)
Aside from the aforementioned symptoms, there are a variety of other types of issues an ASD sufferer may face. Such symptoms may or may not be due to comorbid disorders. These include:
Very active or hyper
Expresses unusual reactions toward things observed by 5 senses
Extremely fearful of harmless things, or no fear of dangerous things
Aggression, anger control issues, temper tantrums, etc.
Abnormal emotional reactions and moods
Abnormal eating and sleeping patterns
While these symptoms are all associated with autism spectrum disorders, not every person with an ASD will experience all of these symptoms, and the degree to which each symptom affects an individual can vary greatly from one person to the next.
