Serious Symptoms Of Chronic Inflammatory Demyelinating Polyneuropathy (CIDP)

Loss Of Reflexes

Reflex describes the sudden, involuntary movement of a body part in response to certain stimuli. Human reflexes are automatic responses the body makes without the individual having to think about it consciously. Reflexes work through what is called reflex arcs, where the reaction occurs before the actual impulse even reaches the brain. Monosynaptic reflexes are made of a motor neuron and a sensory neuron, and polysynaptic reflexes contain multiple interneurons. The reflexes most affected by chronic inflammatory demyelinating polyneuropathy are their deep tendon reflexes. Deep tendon reflexes are considered monosynaptic reflexes and occur when a rapid muscle stretch provides stimulation to the individual's muscle spindles. The sensory root relays this impulse to the motor neuron that supplies the particular muscle, which results in a rapid muscle contraction. Reflexes are lost in CIDP patients because the immune system destroys the myelin sheath around the lower motor neurons, interrupting the process of impulse communication.
