Can caffeine permanently alter brain?
The authors say that effects of caffeine can build up over time and lead to measurable changes in the brain: If you’re blocking adenosine receptors with caffeine over the long term, this can result in “adaptive changes and lead to chronic alterations of receptor expression and availability,” the authors write.
How do I quit caffeine?

Does caffeine kill brain cells?
So when caffeine is present in the brain, it competes with adenosine to bind to the same receptors. However, caffeine doesn’t slow the firing of your neurons like adenosine does. Instead, it prevents adenosine from slowing you down. Caffeine promotes central nervous system stimulation, making you feel alert.
Is coffee good for your brain?
Because caffeine acts as a central nervous stimulant, people usually take it to feel more alert and energetic. Caffeine can improve mood and help people feel more productive. It is believed to work by blocking the neurotransmitter adenosine’s receptors, increasing excitability in the brain.
