But you can take advantage of treatment as soon as you suspect your child has developmental delays.

Ask your doctor to refer you to early intervention services. Early intervention is a federally funded program for infants and toddlers with disabilities. Children who demonstrate several early warning signs may have developmental delays.

Autism is a spectrum condition, which means that children will have different experiences of day-to-day living. Children who are more than five years old and on into their teenage years, who have mild symptoms and are towards the higher functioning range of the autism spectrum, may: [10] [17] [19] [20]. Children who have more severe symptoms and are towards the lower functioning range of the autism spectrum may: [10] [17] [19] [20]. It is rare for delayed verbal communication to develop after the age of five years old.

As such, a significant proportion of children with autism spectrum disorder will become nonverbal teens and adults. Autism spectrum disorder is a lifelong condition and some people with autism spectrum disorder are not diagnosed until they are adults. This could be because they fall into the higher functioning range of the autism spectrum and their symptoms are less severe, or because they were misdiagnosed with a condition such as attention deficit hyperactivity disorder or obsessive compulsive disorder.

Although treatment can improve some outward symptoms, people with autism will always process sensations such as sound, sight, touch and smell in different ways. Autism is a spectrum condition, which means that adults will have different experiences of day-to-day living.

An adult with mild symptoms, who is towards the higher functioning range of the autism spectrum, may: [7] [24] [25]. An adult who is towards the lower functioning range of the autism spectrum may: [10] [25] [26] [27]. Employment may present a challenge for adults with autism. People with autism are likely to need adjustments to be able to work productively, such as lights that do not flicker or a quiet space to work in. One common sign of autism spectrum disorder in adults is anxiety.

Signs of anxiety can include: [29]. The ratio of boys to girls diagnosed with autism spectrum disorder is However, there is some evidence that autism is going undiagnosed in girls, particularly those who are at the higher functioning end of the spectrum. There is discussion around whether girls and women with autism may display different symptoms to boys and men, and that the current diagnostic criteria may be biased towards boys and stereotypical male behavior.

Girls and women may also be better able to mask difficulties with social interactions than boys, and this may delay a diagnosis. New diagnostic criteria may be needed to assess ASD in girls and women. Past theories, including controversies such as the extreme male brain, may have led to under-referral and under-diagnosis of autism spectrum disorder in girls and women.

Signs that a girl may have autism include: [35] [36]. There are also higher rates of anxiety, depression and eating disorders among girls with autism spectrum disorder than among boys.

People with Asperger syndrome are generally considered to be on the higher functioning end of the autism spectrum. It is still a form of autism and is a lifelong condition. Signs and symptoms that are typical of people with Asperger syndrome include: [37] [38] [39]. Many people with autism spectrum disorder engage in repetitive behaviors , known as stereotypy, self-stimulatory behavior or stimming.

Examples of these kinds of behavior include: [19] [40] [41]. These behaviors provide the person with a form of sensory input that the person finds appealing or helpful.

There are various reasons why someone could be engaging in self-stimulatory behavior: [19] [41]. Some people with autism develop extreme preferences, dislikes or practices around food , for example: [42] [43]. People with autism spectrum disorder may exhibit behaviors which put themselves at risk , cause difficulties for people around them or which are not socially acceptable. Around 50 percent of people with autism engage in behavior that can cause themselves harm when they feel frustrated, overwhelmed or unwell.

Such behaviors can include: [44] [45]. A person with autism who feels frustrated, overwhelmed or feeling unwell may also display physically aggressive behavior. This can include: [46] [47].
