My son has autism and dyspraxia which affects motor and planning. He also has communication difficulties and misophonia. I set alarms on his mobile phone to remind him to do certain things, and we have lots of visual displays around the home to encourage him to become more independent. Regarding the young person you are enquiring for, do they have any specialist intervention or therapist they see regularly? Do they attend a specialist education provision or supported living/working scheme? many of these community and medical teams can help a young person deal with their feelings about a diagnosis and also help them manage their self care around their health issues.
