Hyporeflexia
Hyporeflexia (pronunciation: /ˌhaɪpoʊrɪˈflɛksiə/) is a medical condition characterized by below normal or absent reflexes (such as the knee-jerk response). It is often a symptom of various neurological disorders and can be a sign of serious conditions such as Guillain-Barré syndrome or Charcot-Marie-Tooth disease.
Etymology
The term "Hyporeflexia" is derived from the Greek prefix "hypo-" meaning "under" or "below normal", and the Latin "reflexus" meaning "reflection".
Symptoms and Diagnosis
Hyporeflexia is typically diagnosed through a neurological examination where the doctor tests the patient's reflexes. Symptoms of hyporeflexia can include muscle weakness, fatigue, and loss of balance. In severe cases, it can lead to paralysis.
Causes
Hyporeflexia can be caused by damage to the peripheral nerves or the spinal cord. It can also be a symptom of certain diseases such as Guillain-Barré syndrome, Charcot-Marie-Tooth disease, and poliomyelitis. Certain medications, such as those used for anesthesia, can also cause hyporeflexia.
Treatment
Treatment for hyporeflexia typically involves addressing the underlying cause. This can include medication, physical therapy, or in some cases, surgery.
