A demyelinating disease refers to any disease affecting the nervous system where the myelin sheath surrounding neurons is damaged. [1] This damage disrupts the transmission of signals through the affected nerves, resulting in a decrease in their conduction ability. Consequently, this reduction in conduction can lead to deficiencies in sensation ...
Neurology. Acute disseminated encephalomyelitis (ADEM), or acute demyelinating encephalomyelitis, is a rare autoimmune disease marked by a sudden, widespread attack of inflammation in the brain and spinal cord. As well as causing the brain and spinal cord to become inflamed, ADEM also attacks the nerves of the central nervous system and damages ...
Encephalomyelitis is inflammation of the brain and spinal cord. Various types of encephalomyelitis include: Acute disseminated encephalomyelitis or postinfectious encephalomyelitis, a demyelinating disease of the brain and spinal cord, possibly triggered by viral infection. [1][2] Encephalomyelitis disseminata, a synonym for multiple sclerosis.
Multiple sclerosis and other demyelinating diseases of the central nervous system (CNS) produce lesions (demyelinated areas in the CNS) and glial scars or scleroses. They present different shapes and histological findings according to the underlying condition that produces them. Demyelinating diseases are traditionally classified in two kinds ...
Seropositive Devic's disease, according to the diagnostic criteria described above. Limited forms of Devic's disease, such as single or recurrent events of longitudinally extensive myelitis, and bilateral simultaneous or recurrent optic neuritis. Asian optic-spinal MS - this variant can present brain lesions like MS. [18]
Neurology. Subacute combined degeneration of spinal cord, also known as myelosis funiculus, or funicular myelosis, [1] also Lichtheim 's disease, [2][3] and Putnam-Dana syndrome, [4] refers to degeneration of the posterior and lateral columns of the spinal cord as a result of vitamin B 12 deficiency (most common).
Neurology. Chronic inflammatory demyelinating polyneuropathy (CIDP) is an acquired autoimmune disease of the peripheral nervous system characterized by progressive weakness and impaired sensory function in the legs and arms. [1] The disorder is sometimes called chronic relapsing polyneuropathy (CRP) or chronic inflammatory demyelinating ...
Foix–Alajouanine syndrome, also called subacute ascending necrotizing myelitis, [1] is a disease caused by an arteriovenous malformation of the spinal cord. [2] In particular, most cases involve dural arteriovenous malformations that present in the lower thoracic or lumbar spinal cord. The condition is named after Charles Foix and Théophile ...
