What causes hyperreflexia in lower extremities?
Common causes of hyperreflexia include focal brain lesions (typically causing unilateral hyperreflexia), cervical myelopathy, and motor neuron disease (amyotrophic lateral sclerosis, ALS). The latter is characterized by a combination of upper and lower motor neuron findings.
What are hyperreflexia a symptom of?
Causes. The most common cause of autonomic hyperreflexia is spinal cord injury. The nervous system of people with this condition over-responds to the types of stimulation that do not bother healthy people.
What does brisk reflexes in legs mean?
Brisk reflexes may develop when neurons deteriorate. These neurons are also known as the upper motor nerve cells. Other causes of brisk reflexes are associated with neurological conditions, including: Hyperthyroidism: This condition can cause too much thyroid hormone to be released in your body.
Can a pinched nerve cause hyperreflexia?
When the spinal cord becomes compressed in the cervical region, it compromises your brain’s functioning and motor skills. Studies conclude that when cervical myelopathy is left ignored, it can cause muscle contractions, gait disturbance, pathologic reflexes, and hyperreflexia.
What diseases cause brisk reflexes?
Causes
- 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.
What conditions can mimic ALS?
A number of disorders may mimic ALS; examples include:
- Myasthenia gravis.
- Lambert-Eaton myasthenic syndrome.
- Lyme disease.
- Poliomyelitis and post-poliomyelitis.
- Heavy metal intoxication.
- Kennedy syndrome.
- Adult-onset Tay-Sachs disease.
- Hereditary spastic paraplegia.
Is hyperreflexia a symptom of radiculopathy?
When diagnosing a patient with radiculopathy, it is important to test for cervical myelopathy. Patients with myelopathy will present with upper motor neuron signs including hyperreflexia, changes in gait, and also have difficulty with fine motor tasks (changes in handwriting, buttoning shirts, etc.).
Can cervical myelopathy cause hyperreflexia?
Cervical myelopathy is a condition describing a compression of the spinal cord at the cervical level of the spinal column resulting in spasticity (sustained muscle contractions), hyperreflexia, pathologic reflexes, digit/hand clumsiness, and/or gait disturbance.
How do you prevent hyperreflexia?
Prevention
- Do not let the bladder become too full.
- Pain should be controlled.
- Practice proper bowel care to avoid stool impaction.
- Practice proper skin care to avoid bedsores and skin infections.
- Prevent bladder infections.
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 could cause my hyperreflexia?
Anxiety and trepidation
What can cause hyper reflexes?
a dangerous spike in blood pressure
What causes hyper reflexes?
– blood pressure – heart and breathing rates – body temperature – digestion – metabolism – balance of water and electrolytes – production of body fluids – urination – defecation – sexual response
What causes hyperreflexia and clonus?
key finding: clonus Clonus may be conceptualized as a form of profound hyperreflexia, wherein each muscle contraction triggers another reflexive contraction. Causes of clonus include: Upper motor neuron dysfunction (e.g. due to stroke, trauma, cerebral palsy, or multiple sclerosis). Serotonin syndrome. Anticholinergic toxicity. Baclofen withdrawal.
