Autism spectrum disorder (ASD) is a range of complex neurodevelopment disorders, characterized mainly by social impairment and communication difficulties. It is a spectrum condition, which means that while all people with Autism share similar difficulties, their condition will affect them differently. According to the WHO, recent reviews estimate a global median prevalence of 62/10 000, that is one child in 160 has an autism spectrum disorder. In the USA, The Centers for Disease Control and Prevention says an estimated 1 in 68 persons has been identified with Autism Spectrum Disorder and in the UK 1 in 100. No official statistics are known in Trinidad and Tobago.
Some people with high-functioning Autism are able to live relatively independent lives while others with moderate or low-functioning Autism may need a lifetime of family and specialist support. People on the Autism spectrum may also experience over or under sensitivity to sounds, touch, tastes, smells, light or colors as well as anxiety as they try to make sense of the world around them.
