Non-synaptic function of the autism spectrum disorder-associated gene SYNGAP1 in cortical neurogenesis

If you don’t get why they’re saying a specific thing, ask them to slow down and explain. Clear communication is important to getting things right.”I’m not sure why you said I might have ADHD instead of autism. I don’t usually struggle to pay attention in class, and I had a lot of developmental delays in early childhood.” They tend to have a broad face with full cheeks, deep-set eyes, and a strong jaw.

Part of the reason for this delay is that the symptoms of autism can look much like those of other conditions, which is why autism screening is a multistep process involving several different health and mental health professionals. In the brain, nerve cells transmit important messages that regulate body functions — everything from social behavior to movement. Imaging studies have revealed that autistic children have too many nerve fibers, but that they’re not working well enough to facilitate communication between the various parts of the brain. Scientists think that all of this extra circuitry may affect brain size. Although autistic children are born with normal or smaller-than-normal brains, they undergo a period of rapid growth between ages 6 and 14 months, so that by about age four, their brains tends to be unusually large for their age. Genetic defects in brain growth factors may lead to this abnormal brain development.

Many anxiety disorders have symptoms that are better explained by ASD itself, or are hard to distinguish from ASD’s symptoms. Exposure to air pollution during child pregnancy, especially heavy metals and particulates, may increase the risk of autism. Some, such as the MMR vaccine, have been completely disproven. Higher rates of self-injury are also noted in socially isolated people with autism. Studies have shown that socialization skills are related factors to self-injurious behavior for people with autism. A history of neurodevelopmental conditions or mental health conditions. What is the male-to-female ratio in autism spectrum disorder?

However, the study’s 1% figure may reflect an underestimate of prevalence in low- and middle-income countries. The number of people diagnosed has increased considerably since the 1990s, which may be partly due to increased recognition of the condition. Several parent-mediated behavioral therapies target social communication deficits in children with autism, but their efficacy in treating RRBs is uncertain. Several prenatal and perinatal complications have been reported as possible risk factors for autism. While research is not conclusive on the relation of these factors to autism, each of these factors has been identified more frequently in children with autism, compared to their siblings who do not have autism, and other typically developing youth.

Another way in which girls and women with autism tend to differ from boys is in terms of their interests. Part of the diagnostic criteria for autism in the DSM-5 is “restricted, repetitive patterns of behaviour, interests or activities”10—and in this area, girls and women often have different types of interests from men with autism. Some autistic children react strangely to strong smells, bright colors, unusual textures, and specific noises, even if those stimuli don’t seem strong to other people.

Mild Autism Traits in Adults

A young autistic boy who has arranged his toys in a rowASD includes a wide variety of characteristics. Some of these include behavioral characteristics which widely range from slow development of social and learning skills to difficulties creating connections with other people. Autistic people may experience these challenges with forming connections due to anxiety or depression, which they are more likely to experience, and as a result isolate themselves. Being autistic doesn’t mean a person is uninterested in sex.

Distinguishing Autism From Other Conditions

Chelation therapy – Following the school of thought that autism may be caused by exposure to environmental toxins, such as mercury and other heavy metals, chelation uses a chemical agent to bind to and remove these metals from the body. In 1995, Dr. Simon Baron-Cohen of Cambridge University proposed a new theory about autism.

Sometimes an autistic person with mild traits may get a diagnosis—just not an autism diagnosis. How much support autistic people with mild traits need depends on many factors and varies from person to person, even though they have the same level-1 diagnosis.

Schools are also required to create an Individualized Education Program , which specifically addresses the child’s unique learning needs. Scientists continue to look for clues to the origins of autism.

But recent research has increasingly questioned these findings, as the “double empathy problem” theory argues that there is a lack of mutual understanding and empathy between both neurotypical persons and autistic individuals. Autism is currently defined as a highly variable neurodevelopmental disorder that is generally thought to cover a broad and deep spectrum, manifesting very differently from one person to another. Some have high support needs, may be non-speaking, and experience developmental delays; this is more likely with other co-existing diagnoses. Others have relatively low support needs; they may have more typical speech-language and intellectual skills but atypical social/conversation skills, narrowly focused interests, and wordy, pedantic communication.
