Excitotoxicity: The Focus Trap That Fries Your Brain
How to Protect Your Brain and Thrive in a High-Pressure World
⚡️ Welcome to a 🔒 subscriber-only edition 🔒 of Focus Fuel. Each week I send a no-BS neuroscience-backed method for founders & high-achievers to maximise their energy & impact. ⚡️
Founders and creators are obsessed with more.
Chasing deep work, flow states, and peak performance. Trying to maximise every minute.
But what if this obsession is backfiring and actually sabotaging your success?
Never wanting to waste a moment could be leading you towards a dangerous condition known as Excitotoxicity.
It's so dangerous that it can destroy brain cells, shrink memory centres, and is linked to diseases like Alzheimer's [1].
In this deep dive, we’ll cover:

The Hidden Danger: What is Excitotoxicity?
Imagine a gardener decides to generously water their plants every day, thinking more water equals healthier plants.
Initially, the plants appear lush and vibrant, thriving under the extra attention. This is your brain on glutamate, the most abundant excitatory neurotransmitter.
Glutamate is the fuel that powers your cognitive performance, facilitating communication between neurons. It's the driving force behind learning, memory, and those electrifying "aha!" moments that make you feel like you can conquer the world [2].
But here's the catch: just as overwatering can harm plants, excessive glutamate can damage your brain.
As the gardener continues to water unchecked, the life giving water begins to actually drown the plants. Leaves turn yellow, stems soften, and the plants' shape sags.
Excitotoxicity is the dark side of the very thing that makes you feel invincible.
Sustained high levels of glutamate cause neurons to become overstimulated, leading to cell damage and even cell death. The memory centres of your brain, like the Hippocampus, start to shrink, impairing your ability to learn and remember. Inflammation and oxidative stress increase, accelerating aging and cognitive decline.
Excitotoxicity is exciting in the moment but toxic later.
Excitotoxicity is the silent assassin that can turn your creative flow into a mental meltdown.
The worst part?
You might not even realize it's happening until it's too late.
The Glutamate Gamble: When Your Brain's Fuel Becomes Toxic
Just like the gardener who thinks that more is better, you might be tempted to push yourself harder and longer to achieve more.
But this is a dangerous game — what was once brain fuel can quickly turn into a toxic liability.
When you're in the zone, firing on all cylinders, your brain is releasing a flood of glutamate. This feels incredible at first. You're focused, creative, and bursting with ideas. But as you continue to push, glutamate levels keep rising. That initial euphoria starts to give way to something more sinister.
Excessive glutamate is like overwatering your brain.
The more you overstimulate your brain, the more glutamate it releases. Over time, this excessive stimulation causes irreversible damage. It's a vicious cycle of damage and dysfunction.
The consequences of chronic Excitotoxicity are severe:
Neurons become overstimulated, leading to cell damage and death [5]
Inflammation and oxidative stress increase, accelerating aging and cognitive decline [4]
Memory centres like the Hippocampus start to shrink, impairing learning and recall [3]
Your risk of neurodegenerative diseases like Alzheimer's and Parkinson's skyrockets [6]
In fact, studies have shown that people with Alzheimer's disease have significantly higher levels of glutamate in their brains compared to healthy individuals [7].
Excitotoxicity is both bad short term and long term. It’s a gamble, with stakes that are too high to ignore.
But how can you achieve peak performance without the negative impact of Excitotoxicity?
