Research suggests that the ageing process in the brain may be linked to a breakdown in protein production. Scientists have discovered that as we age, the protein-making machinery within brain cells can become 'jammed up,' leading to a decline in cognitive function. This discovery offers potential new avenues for developing interventions aimed at maintaining brain health and cognitive sharpness as individuals grow older. Further research is focused on understanding the mechanisms behind this protein production decline and identifying ways to restore efficient protein synthesis in ageing brains.
