Many autistic individuals also experience the world with different sensory sensibilities.
These may be being particularly sensitive or under sensitive to certain kinds of light, sound, smell, taste or touch. Therefore may also look to experience sensory inputs, in ways that other people may find unusual such as liking very strong pressure or hating high musical notes.
All of these can make the world a very difficult place but with understanding, patience and sometimes with proper resources and advice things can be made easier.
Autistic people sometimes have other conditions such as Attention Deficit Hyperactivity Disorder (ADHD), learning difficulties, depression and physical health problems especially bowel and stomach ailments.
It is important that these are dealt with appropriately and that the autism diagnosis is not used as an excuse not to treat these.
