What is a demyelinating disorder?
A demyelinating disease is any condition that results in damage to the protective covering (myelin sheath) that surrounds nerve fibers in your brain, optic nerves and spinal cord. When the myelin sheath is damaged, nerve impulses slow or even stop, causing neurological problems.
Is Hyperreflexia a sign 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.
Does demyelination mean MS?
What is demyelination, and what causes it? Demyelination occurs when myelin, which is the protective coating of nerve cells, sustains damage. When this happens, neurological problems can occur. Demyelination can result from various medical conditions, including multiple sclerosis (MS).
What is hyperreflexia a symptom of?
Hyperreflexia is a sign of upper motor neurone damage and is associated with spasticity and a positive Babinski sign.
What is TM test?
These tests are painless and is used to detect nerve damage and peripheral vascular disease (PAD) due to various medical conditions that we can review with you. The TM-Flow System helps us differentiate vascular from neuropathic symptoms. TM-Flow is a unique Medical Device Data System that makes a difference.
What is Lhermitte’s sign?
Lhermitte’s sign (also known as Lhermitte’s phenomenon and the barber chair phenomenon) describes a transient sensation of an electric shock extending down the spine and/or extremities upon flexion of the neck, often a sequela of neurologic disease. It was first described by Marie and Chatelin in 1917.
What causes the Lhermitte effect?
It is typically triggered by bending the neck forward (putting your chin to your chest). It was named after Jean Lhermitte, a French Neurologist, who established its significance in 1924.
What is the difference between Lhermitte’s and MS?
Lhermitte’s is often described as an electrical shock or buzzing sensation. Your nerve fibers are covered in a protective coating called myelin. In MS, your immune system attacks and destroys myelin in your brain and spinal cord, which slows down the signal that travels between nerves.
What tests are used to diagnose Lhermitte’s sign?
Often, diagnostic tests such as cervical spine MRI or lumbar puncture (LP, often also called a spinal tap) can help identify the disease that is causing you to experience Lhermitte’s sign.
