The severity of symptoms of autism can vary greatly. Common symptoms include difficulty with communication, difficulty with social interactions, obsessive interests and repetitive behaviours. The symptoms may appear earlier or later. Early symptoms may include a marked delay in language or social development. The symptoms can look different in different people. If you think you may be living with autism spectrum disorder (ASD), learn these signs and symptoms in adults.
Different parts of the brain are affected due to autism such as the cerebellum, hippocampus and amygdala, lobes of the cerebrum, ventricles and caudate nucleus. New research is challenging the long-held belief that autism affects only those regions of the brain that are responsible for controlling social interaction, communication, and reasoning etc.
