What happens to deep tendon reflexes in elderly individuals?

In elderly individuals, deep tendon reflexes are typically decreased due to several age-related physiological changes. As people age, there is a natural decline in the functioning of the nervous system, which includes both the central and peripheral components. The reduction in the number of neurons and synaptic connections can lead to slower reflex responses.

Additionally, conditions such as decreased muscle mass, changes in tendon stiffness, and overall diminished sensory and motor function can contribute to a reduction in the reflex intensity. While variations can occur among individuals, the general trend observed is that deep tendon reflexes are not as brisk or pronounced as they would be in younger adults. This decreased reflex activity is a normal part of the aging process and reflects the body's adaptation as it ages.
