One or a combination of four basic conditions can cause primary infant motor reflex dysfunction or deeper pathology: Congenital Disorders. Trauma. Prolonged, Intermittent or Chronic Stress. Non-Congenital Disease. Each of these conditions can cause the central nervous system, sensory system, or motor system to become compromised.
What causes slow or fast reaction time?
Our reflexes depend upon our processing speed. The shooting games involve visual and auditory processing of the stimuli. Now, if the processing speed is less, the output will be likewise. About myeline sheaths...... there need not be any problem with the sheaths. The reflex in association with myelin sheaths is of some other kind.

What does it mean if you have weak reflexes?
When reflex responses are absent this could be a clue that the spinal cord, nerve root, peripheral nerve, or muscle has been damaged. When reflex response is abnormal, it may be due to the disruption of the sensory (feeling) or motor (movement) nerves or both.
What diseases affect your reflexes?
Spinal cord injuries are most likely to cause these unusual reflexes, but other disorders that can result in abnormal reflexes include brain tumors, brain trauma, stroke, meningitis, or spinal cord injuries.

What does lack of knee reflex mean?

Modifying reaction time
Reflexes do play a role in reaction time. Some people are born with faster reflexes. Electrical impulses actually travel more quickly through their nerves. But you can also speed up nerve conduction through practice.
Reflexes and age
Reflexes do slow with age. Physical changes in nerve fibers slow the speed of conduction. And the parts of the brain involved in motor control lose cells over time. But the effect of age on reflexes and reaction time varies greatly from person to person. You can actually slow down—even reverse—the effects of aging by staying physically active.
