I feel very blessed that I'm able to give him everything that he needs, and that's why I want to help as many mothers as I can,” she said. What is autism? Autism also known as autism spectrum disorder (ASD) is a neurological and developmental disorder that affects how people interact with others, communicate, learn, and behave. According to the World Health Organization (WHO), about 1 in 100 children has autism. ASD begins before the age of 3 years and can last throughout a person's life, although symptoms may change over time. Some children show ASD symptoms within the first 12 months of life. This developmental condition is characterized by persistent difficulties in social communication and interaction, challenges in sensory processing, repetitive behaviours, interests, or activities, and some instances of intellectual disability, all of which occur at varying levels of severity. People with this disorder are at high risk of social isolation, and academic or employment difficulties, and require psychosocial support into adulthood. Early ASD diagnosis can improve the lives of such individuals.What are the early signs of ASD? People with autism often have difficulty with social communication and interaction, along with restricted or repetitive behaviors or interests. While there are common signs and symptoms associated with Autism Spectrum Disorder (ASD), it's important to remember that some individuals without ASD may also exhibit similar traits. Diagnosis should always be made by professionals based on a full evaluation.Here are some early signs according to CDC:Social communication and interaction skillsAvoids eye contactUnresponsive to name by 9 months of ageDoes not show facial expressions such as happy, sad, angry, and surprised by 9 months of ageDisinterest in simple interactive games like pat-a-cake by 12 months of ageUses few or no gestures by 12 months of age Does not share interests with others by 15 months of age Does not point to show you something interesting by 18 months of ageDoes not notice when others are hurt or upset by 24 months (2 years) of ageDoes not notice other children or join them in play by 36 months (3 years) of ageDoes not pretend to be something else, like a teacher or superhero, during play by 48 months (4 years) of ageDoes not sing, dance, or act for you by 60 months (5 years) of age Restricted or repetitive behaviors or interestsGets upset when the order of lined up toys or other objects is changedRepeats words or phrases over and over (called echolalia)Plays with toys the same way every timeIs focused on parts of objects (for example, wheels)Minor changes irk themObsessive interestsSticks to a specific routineFlaps hands, rocks body, or spins self in circlesUnusual reactions to sound, smell, taste, look, or feelOther signsDelayed language skillsDelayed movement skillsDelayed cognitive or learning skillsHyperactive, impulsive, and/or inattentive behaviorEpilepsy or seizure disorderUnusual eating and sleeping habitsGastrointestinal issues (for example, constipation)Unusual mood or emotional reactionsAnxiety, stress, or excessive worryLack of fear or more fear than expected
