Autism is a developmental disorder with symptoms that appear within the first three years of life. Autism spectrum disorder is a condition related to brain development that impacts how a person perceives and socializes with others, causing problems in social interaction and communication. It’s commonly known as autism spectrum disorder.
The word “spectrum” indicates that autism appears in different forms with varying levels of severity. Each individual with autism has their own unique strengths, symptoms, and challenges which varies from each child. likely to have a unique pattern of behaviour and level of severity — from low functioning to high functioning Autism spectrum disorder (ASD) is a broad term used to describe a group of neurodevelopmental conditions.
Asd is nearly 4 times more often in boys than in girls.
It is seen
that 1 child in 100 is autistic. A recent research study says autism
affects an estimated 1 in 36 children in the United States today.
Prevalence
About 1 in 36 children has been identified with autism spectrum disorder (ASD) according to research articles and the Autism developmental disorder community. ASD occurs in all racial, ethnic, and socioeconomic groups.
About 1 in 6 (17%) children aged 3–17 years were diagnosed with a developmental disability, as informed by parents, during a study period of 2009-2017. These included autism, attention-deficit/hyperactivity disorder, blindness, and cerebral palsy, among others.
In recent research 2019-2022 studies say that the cases of an autistic children are found to be more i.e(12%) than previous studies of 2017
Also autistic children have trouble expressing their feelings or understanding people around them. They have problems also in normal communication like talking, or very slow or limited talks with no proper pace with their parents. They talk in unusual tone or pace that can range from high-pitched or low-pitched or sometimes too low tones or to robotic or flat.
They also posses animal behaviour to express themselves.
If a autistic child feels a topic very interesting to them, for example, they might develop a very strong vocabulary for talking about that one topic. Or some autistic child if they like music or certain rhymes then their sense for music or rhymes is so good that they express verbally like a normal child whilst other topics might have difficulty communicating with others.
Problems with communication and social interaction
ASD issues with communication ranges before 5yrs of age. As communication in a normal child starts from 11/2yrs to 2yr child. These kids will have delayed communication or improper communication. ASD can also be found in adults after the age of 8-10yrs called as adult with autism spectrum disorder
Below are the signs of autism seen in children after birth :
Restricted or repetitive patterns of behaviour or activities
Apart from the communication and social issues mentioned above, autism also includes symptoms related to body movements and behaviours. which include:
In few autistic child or adult with autism spectrum disorder we also see other symptoms like
Causes
Autism spectrum disorder is a genetic developmental disorder. It has lots of complexity of the disorder, and the symptoms and severity varies in every child of autism , causes are both genetics and environmental factors.
Genetic causes – Several different genes appear to be involved in autism spectrum disorder. For some children, autism spectrum disorder can be associated with a genetic disorder, such as Rett syndrome or fragile X syndrome, developmental delay disorder where as in other children, genetic changes (mutations) may increase the risk of autism spectrum disorder. Still other genes may affect brain development or the way that brain cells communicate, or they may determine the severity of symptoms. Some genetic mutations seem to be inherited, while others occur suddenly.
Some of the common genetic mutations which causes autism are fragile x, 22q13 deletion, 1q21.1 microdeletion, chromosome 18 deletion (Distal 18q deletion syndrome), chromosome 15 deletion (15q13.3 microdeletion), chromosome 15 duplication (Duplication of 15q11-13 chromosome region), Chromosome 22 duplication, etc.
Environmental causes – though Researchers say that the vaccinations doesnt have much effect on autistic child but also other autistic clinicians claim that factors such as viral infections, medications or
complications during pregnancy, or air pollutants play a role in triggering autism spectrum disorder and also the vaccinations complication like over exaggerated response from the child after vaccination apart from normal raise of temperature and redness of the injected part.
