What is the primary observation regarding poor balance in older adults linked to?

The primary observation regarding poor balance in older adults is linked to nervous system conditions. As individuals age, they often experience changes in their nervous system, which can affect their proprioception, reaction times, and coordination. This deterioration can be attributed to various factors, including neuropathy, cognitive decline, and conditions such as Parkinson's disease. These neurological changes can significantly impact balance and stability, making it more challenging for older adults to maintain their equilibrium, especially in dynamic situations or when performing multiple tasks simultaneously.

In contrast, muscle gains, improvements in mobility, and enhanced focus in tasks tend to contribute positively to balance rather than being linked to poor balance. Although some older adults may experience muscle weakness that affects their balance, the overarching issues associated with neurological function play a more significant role in the observed balance deficits in this population.
