What causes hyporeflexia? Hyporeflexia is usually the result of damage to the motor neurons in the central nervous system. Motor neurons are responsible for transmitting signals from the brain to the rest of the body to produce muscle movement.

What deficiency causes hyporeflexia?

Hyporeflexia is generally associated with a deficit in the lower motor neurons (at the alpha motor neurons from spinal cord to muscle), whereas hyperreflexia is often attributed to lesions in the upper motor neurons (along the long, motor tracts from the brain).

What does it mean if you have hyporeflexia?

Hyporeflexia is an absent or diminished response to tapping. It usually indicates a disease that involves one or more of the components of the two-neuron reflex arc itself. Hyperreflexia refers to hyperactive or repeating (clonic) reflexes.
