ADHD is a complex disorder with likely involvement of multiple genes; it is not specifically found on a single chromosome. Research suggests that certain genes located on various chromosomes, such as 5, 11, and 17, may contribute to an increased risk of developing ADHD.

Chromosome Disorder
ADHD is classified as a neurobehavioral developmental disorder.
ADHD is genetic. If you think they learned it somewhere, then that is a behavior disorder and not ADHD.
Down syndrome is a chromosomal disorder. It is caused by having 1 extra chromosome (chromosome 21).
ADHD is a brain disorder; it does not affect the body.
ADHD and Attention Deficit Hyperactive Disorder.
ADHD (Attention-Deficit/Hyperactivity Disorder) is not classified as monosomy or trisomy, which are terms related to chromosomal abnormalities where an organism has either one fewer (monosomy) or one extra chromosome (trisomy) than the typical number. ADHD is a complex neurodevelopmental disorder influenced by a combination of genetic, environmental, and neurobiological factors. While genetic factors play a role in ADHD, it does not arise from a specific chromosomal abnormality like monosomy or trisomy.
He has adhd

Sex-linked disorders are passed on the X chromosome. The man supplies the Y chromosome to his sons so the disorder cannot be passed on to the sons. But the man gives his daughter an X chromosome so the disorder can be passed on to her.
