As we age, our mitochondria become less efficient at producing energy, which directly affects the availability of adenosine triphosphate (ATP), the molecule that provides energy for cellular functions. In a preliminary study, scientists used a technique called phosphorous magnetic resonance spectroscopy (31P MRS) to measure ATP levels in the frontal and posterior regions of the brain in healthy older adults. They also assessed cognitive performance using a test called the Montreal Cognitive Assessment (MoCA). The results revealed that higher levels of ATP in the frontal cortex were associated with better cognitive performance on the MoCA. Interestingly, this relationship was specific to the frontal region and did not hold true for the posterior region. These findings suggest that ATP levels in the frontal cortex may play a role in cognitive function in aging individuals. Further research is needed to better understand the functional significance of ATP levels in different areas of the brain and how they impact cognition.
Aging is associated with declines in mitochondrial efficiency and energy production which directly impacts the availability of adenosine triphosphate (ATP), which contains high energy phosphates critical for a variety of cellular functions. Previous phosphorous magnetic resonance spectroscopy (31P MRS) studies demonstrate cerebral ATP declines with age. The purpose of this study was to explore the functional relationships of frontal and posterior ATP levels with cognition in healthy aging. Here, we measured frontal and posterior ATP levels using 31P MRS at 3 Tesla (3 T) and assessed cognition using the Montreal Cognitive Assessment (MoCA) in 30 healthy older adults. We found that greater frontal, but not posterior, ATP levels were significantly associated with better MoCA performance. This relationship remained significant after controlling for age, sex, years of education, and brain atrophy. In conclusion, our findings indicate that cognition is related to ATP in the frontal cortex. These preliminary findings may have important implications in the search for non-invasive markers of in vivo mitochondrial function and the impact of ATP availability on cognition. Future studies are needed to confirm the functional significance of regional ATP and cognition across the lifespan.
