How aging affects brain chemicals and movement in primates

Official title: The effect of aging on neurotransmitters and motor performance in a primate model

Funded at Kent State University · NIH-10757057 · Data updated 2026-11-12

This study looks at how getting older affects brain chemicals and movement in chimpanzees, helping us understand more about aging and conditions like Alzheimer's, so we can learn why some animals seem to handle aging better than others.

Who could benefit from this research

Could help

Ideal candidates for this research are older adults, particularly those aged 21 and above, who may be experiencing cognitive decline or are at risk for neurodegenerative diseases.

Less likely to help

Patients who are younger than 21 or do not have any cognitive impairments or risk factors for neurodegenerative diseases may not benefit from this research.

What this research studies

This research investigates how aging impacts neurotransmitter levels and motor performance in nonhuman primates, particularly chimpanzees. By examining the similarities between aging chimpanzees and elderly humans, the study aims to understand the role of neurotransmitters like acetylcholine and dopamine in cognitive and motor functions. The researchers will analyze brain changes and neurotransmitter fluctuations to develop better models for age-related neurological disorders such as Alzheimer's disease. This approach could provide insights into why some primates show fewer cognitive declines despite having Alzheimer's-related brain changes.

Why it matters

Potential benefit: If successful, this research could lead to improved understanding and treatment options for age-related cognitive disorders in humans.

How similar studies have gone: Previous studies have shown some success in understanding age-related changes in neurotransmitters in other primate models, but this specific approach in chimpanzees is relatively novel.
