Brain fog for me became a lot less prevalent recently. I got no idea what it is but I don't want it to stop. I honestly think brain fog is mostly a mentality thing, but I have no evidence to back this up. It doesn't really matter what I eat. The only thing I changed was I started gymming again and I'm taking creatine. I still eat garbage food

Is it not well established that the single most beneficial activity to improve cognition & sense of wellbeing is weight training?

I caught covid for the first time in jan of 2024, the illness itself wasn't that bad for me, like a common cold, but the aftereffects lingered for months. Eventually my ability to smell and taste came back in a few weeks, but the mental brain fog would not let go. I would sleep over 12 hours a night and still be tired. According to my fitness tracker my daily step and energy burn counts were cut in half. It was so ba…

Out of curiosity what brand of gum did you choose? A few years back I had tried nicotine gum to see if it might encourage my sense of smell to improve, it’s been muted since Covid. It helped but the larger effect I noticed was one day in particular my word recall was phenomenal where usually I struggle and always grasping.

Nicotine has lots of benefits, as per many articles on PubMed. That said, tobacco is still one of the worst (unhealthiest) ways to consume nicotine.

What other widespread way of consuming nicotine was there before patches and vapes? I'm all for measures looking to curb smoking, but the issue is that nicotine seems to be put in the same category, at least judging by PSAs in France. Every nicotine-containing product has scary messages on it, although not to the point of actual cigarettes. I think it's the general trend of losing nuance in public discourse. Things a…

Chewing tobacco was probably more popular in the past.

Except that ADHD is older than screens, and exists without drugs or addiction.

Yes, but incidence rates are increasing. You can blame that on better diagnoses, or, more likely in my opinion, some other factors which didn't exist before.

It can be both though, there's ADHD as it is currently understood as a genetic/neurological issue where the dopaminergic system is impacted, and creates all the effects experienced by ADHD sufferers.

There might also be environmental issues, like you mention, that could be creating similar issues but not from the point of a genetic neurological divergence.

That is an important distinction since the treatment for one cause is very different to another.

The incidence rates increasing are very correlated to better diagnoses, 30 years ago most people with ADHD wouldn't be diagnosed unless they fit into the extreme cases of it. That was my experience, as a kid I was very bright but considered "lazy" since I couldn't focus as my peers did out of school, was always interested during classes, and excelled in school even though I could never do my homework or other assignments, constantly forgot important deadlines, it was always stressful but I found ways to manage it. Thirty years later and I fit in the criteria, no idea how my life would've turned out if I knew about it before, my coping/management mechanisms ended up being to lean into the stress and harness it, it made me achieve things but also created a whole other host of issues with anxiety later in life.

I am diagnosed ADHD. I have used dexamphetamine as prescribed which worked pretty well, in moderate dosages because I am sensitive, but I came to dislike the effect it had on me: I felt like I was attached to a horse that kept pulling me around even when I just wanted to stop and take a break. And the fact that I would crash 5 hours later. In 2020, before even knowing I had ADHD, let alone being medicated, I managed…

As someone who can relate: nicotine spray has been a great alternative for me with the following advantages:

- better dose control for sensitive people, since you can use just one puff (unlike a patch, which delivers the full dose)

- much faster onset

Downsides: strong flavour and the need to spit it out if you have a sensitive stomach.

Creatine is supposedly good for cognitive performance, at least that's what I took from a couple of youtube videos I watched.

From what I understand, it increases ATP availability for neurons, which acts as the "energy to your brain"

Sure, but I wouldn't know why that is. All I know is that it makes me feel a hell of a lot better than if I were doing my (bed)->(office desk)->(desk at home) cycle every day.

From what I read there are 1001 reasons why this helps, but a few that stuck with me was that working out creates norepinephrine (which influences your focus/attention), and releases BDNF which supports the growth of new braincells.

TLDR; • Nicotine boosts attention, memory and alertness by releasing dopamine and other neurotransmitters. • It’s far less harmful than tobacco but highly addictive. • Some evidence hints at therapeutic effects in Alzheimer’s, Parkinson’s and schizophrenia models. • Developing brains (foetus, adolescence) show lasting harm in animal studies.

Gwern's page ( https://gwern.net/nicotine ) and personal anecdata seems to go against the claims of nicotine by itself being addictive, especially 'highly addictive'. Smoking (or even vaping) might be 'highly addictive'. But nicotine as eg patches that you glue on your skin doesn't seem to cause much addiction, if any at all.

Fair I am skeptical about smoking even really being addictive - what would you tell people if you found out that your product poisoned people to keep them using it? If enough people believe something it becomes true and most people are absolutely convinced smoking is difficult to give up.

It was, although not sure how healthier or unhealthier it is to smoking tobacco.
