Asian optic-spinal MS - this variant can present brain lesions like MS. [18] Longitudinally extensive myelitis or optic neuritis associated with systemic autoimmune disease. Optic neuritis or myelitis associated with lesions in specific brain areas such as the hypothalamus, periventricular nucleus, and brainstem. [19]
A neurological disease refers to any ailment of the central nervous system, including abnormalities of the brain, spinal cord and other connecting nerve fibres. [8] Where millions of people are affected by neurological diseases on a worldwide scale, [8] it has been identified that the number of different types of neurological diseases exceeds six hundred, [9] any of which an individual can incur.
Large proteins passing into the brain can put neurological tissue at risk of toxic effects. The blood-brain barrier junctions are typically found to have WE lesions located at that region of the brain. [53] An altered blood–brain barrier may cause a perturbed response to certain drugs and foods. [56]
The causes of frontal lobe disorders can be closed head injury. An example of this can be from an accident, which can cause damage to the orbitofrontal cortex area of the brain. [2] Cerebrovascular disease may cause a stroke in the frontal lobe. Tumours such as meningiomas may present with a frontal lobe syndrome. [11]
Further breakdown of the blood–brain barrier, in turn cause a number of other damaging effects such as swelling, activation of macrophages, and more activation of cytokines and other destructive proteins. Astrocytes can heal partially the lesion leaving a scar. These scars (sclerae) are the known plaques or lesions usually reported in MS.
Normally a tumefactive demyelinating lesion appears together with smaller disseminated lesions. Hence the name "tumefactive multiple sclerosis". When the demyelinating lesion appears alone it has been termed "solitary sclerosis" [citation needed] This variant was first proposed (2012) by Mayo Clinic researches.
Causes Idiopathic , stroke , dementia Gerstmann syndrome is a neurological disorder that is characterized by a constellation of symptoms [ 1 ] that suggests the presence of a lesion usually near the junction of the temporal and parietal lobes at or near the angular gyrus .
Some symptoms in adults are specific to the location of the tumor: Tumors in the cerebrum, which controls movement, may cause weakness or numbness to the body. This weakness is often limited to one side of the body. Tumors in the Broca's area of the cerebrum can cause speech difficulties. In extreme cases, the patient may have problems ...
