🧠 Focus, memory & cognition
6 mechanistic pathways · 80 options
'Nootropic' is a marketing word covering at least six unrelated mechanisms. Acetylcholine is not dopamine is not BDNF is not mitochondrial ATP. Work out whether your problem is attention, recall, mental stamina or brain fog — they respond to different pathways, and stacking across pathways is where the real gains are.
The pathways
Cholinergic — attention, encoding & recall
Acetylcholine is the neurotransmitter of attention and memory formation. Most racetams increase acetylcholine turnover without supplying more, which is exactly why people get headaches on them and why a choline source is not optional in this pathway.
Glutamatergic & synaptic plasticity
Long-term potentiation — the cellular basis of learning — runs through AMPA and NMDA receptors. Modulating them raises the ceiling on how readily new connections form, and it is also the pathway where excitotoxicity is a real rather than theoretical concern.
BDNF & neurotrophic signalling
BDNF is the growth factor for neurons — it supports survival, differentiation and synaptic plasticity. Raising it is the most durable form of cognitive enhancement because it changes the structure rather than borrowing against tomorrow's neurotransmitters.
Catecholamine & dopaminergic drive
Dopamine and noradrenaline set motivation, drive and the ability to start. This is the pathway that feels like something — which is also why it's the one with tolerance, crash and dependency built into the mechanism.
Cerebral metabolism & blood flow
The brain is 2% of body weight and 20% of resting energy use. Brain fog is very often a fuel and perfusion problem rather than a neurotransmitter one, and it responds to a completely different set of tools.
Neuroinflammation & membrane integrity
Persistent brain fog with no attention deficit is often glial inflammation rather than a neurotransmitter shortfall. Microglia stuck in an activated state degrade cognition in a way stimulants paper over and do not fix.
Test before you choose a pathway
Every route below can be argued for on mechanism. Only bloodwork tells you which one is actually your problem — and picking the wrong pathway is the most common reason someone concludes "none of this works". Across all 6 pathways, these are the 20 markers worth having in front of you first.

Frequently asked questions
This goal is broken into 6 distinct mechanistic pathways — Cholinergic — attention, encoding & recall; Glutamatergic & synaptic plasticity; BDNF & neurotrophic signalling; Catecholamine & dopaminergic drive and others — across 80 compounds and supplements. Each pathway is a different argument about how the body gets there, so the useful question is which one matches where you are actually stuck.
The one that matches your actual limitation, which bloodwork usually settles faster than guessing. An appetite drug does nothing for someone who already undereats, and a thyroid intervention does nothing if your thyroid is fine. Each pathway page lists the markers that tell you whether it is your problem.
No. The 6 pathways are listed in mechanistic order, not by strength of evidence, and neither are the 80 options inside them. A lot of what works in this space has never had the trial run, and sorting by trial count would bury exactly the compounds you came looking for.
