What is a notable change in the neurological system of geriatric patients?

In geriatric patients, a notable change in the neurological system is brain shrinkage. As individuals age, various physiological changes occur within the brain, leading to a gradual decrease in brain volume. This shrinkage is often associated with a loss of neurons and neuroplasticity, which can affect cognitive functions, memory, and overall brain health.

Research shows that this brain atrophy may contribute to cognitive decline, affecting areas responsible for memory, processing speed, and other cognitive tasks. Understanding this change is crucial for health professionals working with older adults, as it informs assessment, treatment plans, and realistic expectations regarding cognitive health in the geriatric population.

The other choices suggest improvements or increases in neurological function or structure, which do not align with the typical changes observed in aging.
