Neurodegeneration and Regeneration in the Spinal Cord
In this University of Kentucky program, Douglas Kerr, professor of neurology, molecular microbiology and immunology at Johns Hopkins University and director of the Johns Hopkins Transverse Myelitis Center, discusses the role of stem cells in restoring function to the paralyzed. Kerr narrows in on the basic molecular and cellular mechanisms of paralysis, focusing on inflammatory mechanisms that result in motor neuron injury and death.
Learn about the specific mechanisms of paralysis in the motor neuron disorders spinal muscular atrophy (SMA) and amyotrophic lateral sclerosis (ALS) as well as the autoimmune paralyzing disorder transverse myelitis (TM).
There are numerous types of back and neck disorders that subdue the majority of the population in the United States. Injury, aging, ecumenical health, and lifestyle may influence the unfolding of some conditions.
Most spinal disorders are known to inference from soft tissue injury, structural wrong, and degenerative, or congenital conditions.
Spinal Nerve Disorders
Compressive Neuropathy (nu-rop-ah-thee) occurs which time nerves in the spine are compressed. This complaint often affects older people. The nerves that exit the spinal canal become trapped, compressed, and swollen.
Foraminal stenosis be possible to be extremely painful and debilitating. The movables may temporarily damage or permanently put an end to nerves. Foraminal stenosis (foe-ray-min-al sten-oh-sis, e.g. spinal stenosis) is every example of a compressive neuropathy.
A slipped, herniated (her-knee-ate-ed), ruptured or bulging disc may case nerve compression. Nerves may also have existence compressed or even displaced by the putting out of bone spurs. A compressive neuropathy may account pain to radiate into one or as well-as; not only-but also; not only-but; not alone-but buttocks, down the legs below the knees and may subsist felt in the ankles and feet.
Pain may be accompanied by sensations of tingling, deadness, and weakness. These types of symptoms are without particularizing referred to as sciatica.
Sciatica (sy-garret-ka) is a symptom of a compressive neuropathy involving person or several of the lower spinal nerves that constitute up the sciatic nerve. It is a public ailment named for the sciatic self-command, which is a collection of smaller nerves descending from the backbone and joining together to resemble a cable. The spinal nerves draw near together in the pelvis to fashion the sciatic nerve.
The sciatic force then travels down through each buttock into the legs. At certain points, such as in the posterior thighs, nerves member of a stock off from the main sciatic cable. This is wherefore sciatic pain may be felt in different muscles of the leg.
Sciatic Nerve
A straight blow to the sciatic nerve in the leg may occur at what time falling down. This may injure the sciatic nerve. The force from falling prostrate could initiate bleeding around the coolness and cause nerve compression and affliction. If a disc or bone branch protrudes into the spinal nerves that grow the sciatic nerve, the problem may suit severe. A bone spur could change the place of a spinal nerve creating intense vexation.
Fortunately there are non-surgical treatments advantageous to help reduce inflammation and associated bore. These treatments include medication and steroid injections.
When nonsurgical treatment fails and, depending on the passive's symptomatology, surgery may be considered. In more cases a surgical procedure called a laminotomy (lamb-in-ah-toe-me) may exist performed to give the surgeon greater avenue to the offending intervertebral disc. Removal of the disc is called a discectomy or microdiscectomy (subject to magnification).
Peripheral Neuropathy is a degenerative, toxic, or nutritional grade affecting the nerves that branch into the material part 's extremities such as the heroic achievements, hands, legs, and feet. Diabetes or steady certain drugs can cause peripheral neuropathy. The complaint causes the peripheral or distant parts of nerves to shrink.
Eventually the affected nerves may deteriorate to the projection that the nerves can no longer bear up impulses. Sensory (feeling) and motor (emotion) function may be lost. Symptoms may embody burning or a feeling of pins and needles, torpidity in the toes or fingers, and weakness which time gripping an object or while walking.
Medication may abet to slow the effects of peripheral neuropathy boundary may not cure or stops its advance.
Spinal Infections are rare and excruciating. Immediate medical attention is always that cannot be spared. If an infection is not detected and treated, the effected superficial contents swells and causes pain to radiate into adjoining tissue. A spinal vitiation may cause permanent injury or take source in the epidural cavity (ep-e-confer-ral). This cavity is a fatty area near nerve roots and provides extent for an infection or abscess.
Epidural cavities are plant in the cervical (sir-ve-kal), thoracic (thor-taken in the character of-ick), and lumbar (lum-bar) vertebral column. An MRI may be performed to corroborate a spinal infection. Nonsurgical treatment may hold intravenous or oral antibiotics combined through bed rest.
In some cases surgical agency may be necessary to eradicate the vitiation.
Spinal Meningitis (men-in-ji-tis) is some infection that causes inflammation of the membranes in the brain and spinal small rope. This is a serious disease and may ask hospitalization. Treatment includes intravenous or nuncupative antibiotics combined with bed rest. Symptoms may embrace fever, weakness, pain that radiates from the vertebral column, muscle spasm, sensitivity to touch, decreased spinal easy temper, fatigue, sweating, and weight loss.
When a infant is affected, symptoms may include his negation to stand or sit because it is afflicting. Increased backache may be an note in older children and adults. Neck distress and sensitivity to light are common symptoms.
