A recent study has found that used coffee grounds might contain compounds effective in preventing neurodegenerative diseases like Alzheimer’s and Parkinson’s. These compounds help protect brain cells from age-related damage and exposure to environmental toxins.

Published in the Journal of Environmental Research, the study suggests that compounds extracted from coffee residues can be transformed into an effective, eco-friendly treatment, potentially available in the future as affordable preventive tablets.

The secret to these benefits lies in “carbon-based quantum dots” (CACQDs), molecules that can be extracted from used coffee beans. These quantum dots have a high capacity to protect against neurological damage.

The research team from the University of Texas at El Paso (UTEP), led by PhD student Jyotish Kumar under the supervision of Professor Mahesh Narayan, explained that these quantum dots have profound positive effects that may address the root causes of neurological diseases rather than just superficial symptoms.

Kumar added that this treatment aims to address the atomic and molecular bases of these diseases, marking a shift in therapeutic approaches.

Neurodegenerative diseases like Alzheimer’s and Parkinson’s develop slowly and cause a gradual decline in the nervous system. Symptoms usually begin with memory loss and difficulty concentrating, potentially progressing to the loss of ability to perform daily tasks.

Professor Mahesh Narayan, a member of the Royal Society of Chemistry, emphasized the importance of administering these treatments in early stages to slow disease progression. He also highlighted that the abundance of coffee as a source makes it easy to use these quantum dots economically and sustainably.
