Caffeine and brain plasticity: How it affects our thinking

28. 11. 2023 | Natalie Bezděková

A study conducted on regular caffeine consumers has shown that this popular stimulant can affect brain plasticity, a key process associated with learning and memory.

The findings suggest that caffeine consumption may lead to a reduction in long-term potency (LTP), a mechanism that plays a key role in the relationship between neural connections. The researchers focused on regular caffeine consumers and uncovered a possible limitation in the ability to learn and remember things. Put simply, a daily cup of coffee could be affecting our cognitive function. Particularly interesting is that this finding may have implications for the effectiveness of treatments such as repetitive transcranial magnetic stimulation (rTMS), which is dependent on processes such as LTP.

Caffeine, acting as an antagonistic adenosine receptor in the brain, alters synaptic strength and plasticity processes, which may affect our cognitive state. Although these findings are preliminary and require further research, they highlight the need to better understand the impact of daily caffeine consumption on brain functioning and its long-term consequences.

Experts are calling for larger studies to be conducted to shed more light on how caffeine affects brain plasticity. It seems that our favorite morning coffee may have more complex effects than we previously thought.
