Which symptom can commonly indicate hyperactive deep tendon reflexes in patients?

Hyperactive deep tendon reflexes are typically associated with increased excitability of the nervous system, which can lead to involuntary muscle contractions or spasms. Muscle spasms occur as the body responds to overstimulation of the reflex pathways—this can be due to various neurological conditions, electrolyte imbalances, or irritations in the nervous system that heighten reflex activity.

In the context of this symptom, muscle spasms provide a clear indication of the underlying increased reflex activity. Unlike fatigue, confusion, or general weakness, which may point to a variety of different conditions, muscle spasms are more specific and consistently correlated with hyperactive reflexes. They signify that there is an inappropriate or excessive response occurring within the neuromuscular system.
