What does it mean to have hyperreflexia?

Hyperreflexia refers to hyperactive or repeating (clonic) reflexes. These usually indicate an interruption of corticospinal and other descending pathways that influence the reflex arc due to a suprasegmental lesion, that is, a lesion above the level of the spinal reflex pathways.

What happens in hyperreflexia?

Hyperreflexia is defined as overactive or overresponsive reflexes. Examples of this can include twitching or spastic tendencies, which are indicative of upper motor neuron disease as well as the lessening or loss of control ordinarily exerted by higher brain centers of lower neural pathways (disinhibition).

How is hyperreflexia diagnosed?


  1. anxiety and apprehension.
  2. irregular or slow heartbeat.
  3. nasal congestion.
  4. high blood pressure with systolic readings often over 200 mm Hg.
  5. a pounding headache.
  6. flushing of the skin.
  7. profuse sweating, particularly on the forehead.
  8. lightheadedness.

What can cause hyperactive reflexes?

Conditions that often lead to clonus include:

  • amyotrophic lateral sclerosis (ALS), a rare neurological disease that affects muscle control and movements, sometimes known as Lou Gehrig’s disease.
  • brain injury.
  • cerebral palsy.
  • certain metabolic diseases, such as Krabbe disease.

Is hyperreflexia bad?

It’s sometimes called hyperreflexia. More than half of people with a spinal cord injury in the upper back get it. Autonomic dysreflexia is an emergency and needs immediate medical attention. It can be life-threatening.

Is Hyporeflexia serious?

AD can also be a side effect of medication or drug use. AD is a serious condition that’s considered a medical emergency. It can be life-threatening and result in: stroke.

Is hyperreflexia serious?

Is hyperreflexia a symptom of MS?

Problems with muscle control are common in people with multiple sclerosis. Affected individuals may have tremors, muscle stiffness (spasticity), exaggerated reflexes (hyperreflexia), weakness or partial paralysis of the muscles of the limbs, difficulty walking, or poor bladder control.

What causes Hyporeflexia or hyperreflexia?

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

Is hyperreflexia a symptom of ALS?

When the progression of ALS affects it, people die because of breath insufficiency. Remember that the patients have to have both of the motor neurons symptoms – central (spasticity, irritative phenomena, hyperreflexia) and also periferal (atrophy, fasciculations, muscle weakness). ALS is a combined disability!
