Some MS patients develop rapid onset of numbness, weakness, bowel or bladder dysfunction, and/or loss of muscle function, typically in the lower half of the body. [citation needed] This is the result of MS attacking the spinal cord. The symptoms and signs depend upon the nerve cords involved and the extent of the involvement.
In progressive forms of MS, bodily function slowly deteriorates once symptoms manifest and will steadily worsen if left untreated. [ 14 ] While its cause is unclear, the underlying mechanism is thought to be due to either destruction by the immune system or inactivation of myelin-producing cells. [ 4 ]
Researchers from the Mayo Clinic developed an animal model that involved mice receiving twice daily doses of minced pig brain tissue in saline intranasally. Biochemical testing indicated the signature autoantibodies (potassium channel antibodies, myelin basic protein antibodies and calcium channel antibodies) were present in experimental mice ...
Inflammatory demyelinating diseases (IDDs), sometimes called Idiopathic (IIDDs) due to the unknown etiology of some of them, are a heterogenous group of demyelinating diseases - conditions that cause damage to myelin, the protective sheath of nerve fibers - that occur against the background of an acute or chronic inflammatory process.
Brain lesions associated with a clinically isolated syndrome may be indicative of several neurological diseases, like multiple sclerosis (MS) or neuromyelitis optica. In order for such a diagnosis, multiple sites in the central nervous system must present lesions, typically over multiple episodes, and for which no other diagnosis is likely.
Neuroinflammation is widely regarded as chronic, as opposed to acute, inflammation of the central nervous system. [5] Acute inflammation usually follows injury to the central nervous system immediately, and is characterized by inflammatory molecules, endothelial cell activation, platelet deposition, and tissue edema.

Neuroferritinopathy was originally described with hallmark features of neurodegeneration and iron accumulation in the brain, leading it to be classified with other neurodegeneration with brain iron accumulation (NBIA) disorders which share similar symptoms and imaging findings. Over time single-gene causes have been found for many NBIA ...
Functional weakness is weakness of an arm or leg without evidence of damage or a disease of the nervous system. Patients with functional weakness experience symptoms of limb weakness which can be disabling and frightening such as problems walking or a 'heaviness' down one side, dropping things or a feeling that a limb just doesn't feel normal or 'part of them'.
