There is a strong link between autism and ADHD, with both having high heritability and genetic overlap. Common traits shared in ADHD and autism include:
Sensory differences
Executive dysfunction
Hyperfocus and intense interests
Rejection sensitivity
Social challenges
Sleep disturbances
Differences in eye contact
Difficulties with interoception, such as noticing when you are hungry
Although there are many similarities, differences exist; ADHD individuals may crave novelty and exhibit impulsivity, while autistic people often seek routine and similarity. If someone is autistic and has ADHD, which some people refer to as AuDHD, they may experience an internal struggle between these contrasting traits. An AuDHD person is likely to experience a heightened version of the shared autism and ADHD characteristics, such as an intense focus on hobbies and interests, or experience challenges socialising with neurotypical people.
