My brother has adhd is it possible, genetically, if i have it too? because ive been wondering about if i have adhd because i am restless, don't really pay attention, often don't know what i'm doing, cant finish a project, etc theses are symptoms.?

A person performs at their best when they get adequate restorative sleep, have no illness, are properly nourished & in a comfortable setting. I am leery of ever accepting an ADHD diagnosis for an adult that did not have it as a kid but it can happen. You start the process by seeing your doc & ruling out/treating all the listed issues. Only then can you/they consider ADHD.
