ADHD 

ADHD is a neurological disorder, it stands for Attention Deficit Hyperactivity Disorder. It comes in many forms, so it would be hard to explain it in one definition, but no, you can't feel or be ADHD for a period of time and not have it for your whole life.

Person 1: OMG I AM SOOOOOOOOOOO ADHD TODAY!
Person 2: ADHD is a neurological disorder, it stands for Attention Deficit Hyperactivity Disorder. It comes in many forms, so it would be hard to explain it in one definition, but no, you can't feel or be ADHD for a period of time and not have it for your whole life. Now STFU and stop undermining people's experiences.

ADHD 

An overdiagnosed, yet very real disorder that can be used by soccer moms as an excuse for their lazy ass little child to not do work or for the soccer mom to steal their amphetamines (stimulant meds for the disorder) and snort them at three in the morning.

Categorizes a set of behaviors such as inattentiveness and disorganization, hyperactivity, and potential trouble with filters in speech or actions, which is also called impulsivity, memory, and such. May last for multiple years or be until end of life.
It also allows you to see what the world is besides the boring bullshit mundane fucking "world" of """normal""" people.

When you have ADHD while the instructor of your class or your boss is directing you and you already know or think you know what they're talking about, you instantly divert your attention to something infinitely more interesting or relative to you.

Shit monotonous teacher: "Alright kids, you learned this three grades ago, but (insert boring, pointless, meandering, monotonous and drab speech here)"

ADHD child in head, while staring out window.: "Shut up, old cow... Anyway, I can not fucking wait to jack off tonight and also watch that new movie while or after I jack it.. Maybe video games. How about dead chicken corpses for dinner? WOO! I'll tell mom after I get euthanized and shit. Totally cool."

Shit monotonous teacher: "Are you paying attention, Tim Slim Jim?"

ADHD child: "I would be if it weren't for the fact that your lesson is shitty and boring, as well as ultimately pointless and repetitive to me because I don't breathe through my mouth."

Kid gets sent to office and gets in trouble for something that comes naturally to him, especially if it's for inattentiveness or not doing work.
People speculate that ADHD isn't real because of soccermoms and druggies.
Hoo hah, the whole world done fucked up.

ADHD 

ADHD is an impulse control disorder typcially aggravated by inconsistent parenting. Most children with severe cases of ADHD come from households where parents set little if any limits especially in regard to technology such as the Internet and video games.

Parents of children with ADHD always count to three before they unplug the computer.

ADHD 

It seems to be over diagnosed and self diagnosed lot. It's a lot more than just being hyperative or inattentive. While that is part of it, there's also other symptoms like executive dysfunction, auditory processing disorder, sensory processing disorder, rejection sensitive dysphoria, sleep problem, impulsivity, etc. I, a person who has adhd, deals with all of this. I am also unmedicated. you're more susceptible to depression and anxiety as you grow up being different or just being told you're lazy and you're a waste of space. i don't know a lot of the science behind this, but like i really don't care, these are my experiences. my brother has adhd too, him and i grew up with hypocritical parents that were emotionally abusive. well have a nice day <3

ADHD 

A gift, not a curse. Most people with ADHD believe that they need to take adderall/vyvanse/ritalin etc. to be "normal". People with ADHD are usually more creative, exciting, fun to be around, wise (but usually impulsive), original, and see the world in a different way than most people. It is normally a nightmare to parents, but a wonderful thing to kids/teens that can appreciate it and not only focus on the fact that school is more difficult with it.

Source: Someone diagnosed with ADHD and who is often around many other people diagnosed with ADHD as well.

Person 1: Man I hate having ADHD. School is so hard and i cant remember shit. Good thing ive got adderall to make me normal.

Person 2: Instead of whining about how your ADHD makes life so hard, how about enjoying it and making the most of it.
