Eli5- Whats the science behind ADHD?

367 viewsBiologyOther

Why is my brain so scattered and unable to focus on simple tasks? When I take my medications, I feel a lot better, but I’m so curious why this happens in the first place. Am I missing something in my brain? Are neurotransmitters not working? plz.

Like all other psychiatric conditions, we don’t really know and there isn’t much beyond the subjective responses of people. This is why there is no test besides interviewing, questionnaires and psychological testing. The mind is a black box.

We know what drugs like amphetamines do on a biological level because we’ve stuck probes in mice. That doesn’t tell us at all how they affect the mind, which as I said before is a black box. What we do know is mostly based on examining people’s experiences. Stimulant drugs help some people manage their thoughts and executive functions better, and the potential for improvement is greater where the executive function deficit is greater.

Many people add conjecture between those experiences and the drugs, many doctors and the internet is full of it. The reality is we just don’t know. Focus is much more than just dopamine, it is a multilayer system that we don’t understand. Just because a drug dumping your dopamine reserves into your brain helps some people, doesn’t provide adequate conclusion there was anything wrong regarding dopamine transmitters in the first place, we don’t know the many knock-on effects on other systems that will have, and there are over a hundred types of neurotransmitters in the brain and all are important.
