All of this is true. It is a medical condition that can be treated with drugs.

In my families case, my H and son both have this. Neither take any medication but my son is starting to want to. He struggles to stay on task with school, so he is wishing for a magic cure to his inattention.

H says he is just fine the way he is, thank you very much. But his issues, life long & forged in stone it seems, are much harder on me than he realizes.

Some of them are becoming dangerous but still he will not seek help for a diagnosis he received many years ago. He is afraid to take anything & the unknown scares him more than putting his family in harms way. Not logical, right?

So I Struggle to keep things going as I am the ring master in this households' circus.

Diet is VERY important for them. Sugar seems to give a high/low/crash sort of reaction but magnified.
Son takes Omega 3 oils, fish or flax seed oil lubricate the synapses of the brain and help with focus. This is a science based fact that works.
There are several "natural" supplements out there that have varying degrees of usefulness depending on the person.
He also needs a schedule; 50 mins. on for concentration based activities, 30 off. He is working to whittle away the down time.
He has No trouble focusing on fun things and can spend hours in creative mode when allowed to. Everyone is different.
For him, seeing his dad in real time doing his forgetful behaviors all day long, is a real eye opener. So he wants to overcome it and wants to do whatever it takes.

I hope you find the right thing for you. Best of luck with this.
