Brain related diseases

Trusted by Scientists, Designed for You

Born at Leiden University, NeuroJournal was created by neuroscientists, neurologists, and engineers to support people with persistent, misunderstood conditions—like Long COVID.

You're not alone. You're not making it up.

Our mission is to help you prove that to the world—starting with yourself.

What NeuroJournal Tracks

• Concentration dips

• Sleepiness

• Mental overload

• Any symptoms you want to tag

And the best part? You don’t need to do anything extra—just wear a headband and tap your phone when you notice changes.

You’re Not Imagining It.

Brain fog. Fatigue. Trouble focusing. Mood swings. You know something’s off—but it doesn’t always show up in scans or tests.

NeuroJournal helps you track what others can’t see—so you can finally understand your symptoms, and feel understood.

• EEG-based brain tracking from home

• Smartphone taps to log your experiences

• Clear trends & visualizations of your brain health over time

• Private and secure—you control your data

"It gave me back a sense of control."
