Hyperreflexia ( novolat. Hyperreflexia ; other Greek ὑπερ- - super + reflex) - increased segmental reflexes due to the weakening inhibitory effects of the cerebral cortex on the segmental reflex apparatus. It occurs, for example, with the defeat of the pyramidal paths.

An increase in reflexes indicates an increase in the reflex activity of the segmental apparatus (spinal cord, brain stem). The most common cause of increased reflexes is the defeat of the pyramidal pathways - a system through which the inhibitory effects of the cerebral cortex on reflex segmental spinal mechanisms are transmitted. Again, a symmetrical increase in reflexes in the absence of other pathological symptoms does not always indicate the presence of an organic disease; high reflexes can occur in healthy individuals, can be observed in neurotics, with some intoxications, etc.
