Devic S Disease

Devic's disease is a rare autoimmune disease that affects the optic nerve and spinal cord. It is also known as neuromyelitis optica.

This disease was first described by the French physician Eugene Devic in 1894. It is characterized by inflammation (myelitis) of the optic nerve and spinal cord, leading to vision loss and muscle weakness.

The causes of Devic's illness are not completely clear. It is believed to be caused by an autoimmune attack on the myelin sheath of the nerve fibers of the optic nerve and spinal cord. This leads to demyelination, that is, destruction of the myelin sheath. As a result, the conduction of nerve impulses is disrupted.

Main symptoms include:

1. Loss of vision, often bilateral, due to damage to the optic nerve

2. Muscle weakness in the legs, arms and trunk

3. Problems with coordination and balance

4. Sensory disorders

Diagnosis is based on analysis of symptoms, MRI of the brain and spinal cord, and analysis of cerebrospinal fluid.

Treatment mainly involves high doses of steroids to suppress inflammation and immunomodulatory drugs. Physical therapy can help restore motor function. The prognosis depends on the degree of damage to the nervous system.

Thus, Devic's disease is a severe autoimmune disease that affects the optic nerve and spinal cord. Timely diagnosis and treatment are essential to slow the progression of the disease.

DEVIK DISEASE – A DANGEROUS BUT TREATABLE EPIDEMIC DEVIK is a rare acquired neurodegenerative disease in which plaques containing either amyloid or α-synuclein form in the nervous tissue. Affected young people who suffer from 3 or more ophthalmic symptoms are victims of “Devike's disease,” also known as “visual cortical atrophy 4.” The author of this term is N.A. Mamedov. Subsequently, the terms "Purvehile disease" and "sensory neuropathy with complete loss of contrast sensitivity to red, green and blue" were proposed.
