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. [6] Chronic inflammation is the sustained activation of glial cells and recruitment of other immune cells into the brain. It is chronic ...
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.
The symptoms vary greatly, in part, because of the underlying or causing infection. While the inflammation can cause a number of effects such as those mentioned previously, the base infection could cause other symptoms that don't necessarily have to do with the ventriculitis, itself. One of the challenges doctors face in diagnosing ...
Chronic meningitis is a long-lasting inflammation of the membranes lining the brain and spinal cord (known as the meninges).By definition, the duration of signs, symptoms and inflammation in chronic meningitis last longer than 4 weeks. [2]
The cells of the neurovascular unit also make up the blood–brain barrier (BBB), which plays an important role in maintaining the microenvironment of the brain. [11] In addition to regulating the exit and entrance of blood, the blood–brain barrier also filters toxins that may cause inflammation, injury, and disease. [12]
The parasympathetic nervous system (PSNS) is one of the three divisions of the autonomic nervous system, the others being the sympathetic nervous system and the enteric nervous system. [1] [2] The autonomic nervous system is responsible for regulating the body's unconscious actions.
The retina and the optic nerve originate as outgrowths of the brain during embryonic development, so they are considered part of the central nervous system (CNS). [66] It is the only part of the CNS that can be imaged non-invasively in the living organism. The retina nerve fiber layer (RNFL) is thinner than normal in MS patients [67]
The general visceral afferent (GVA) fibers conduct sensory impulses (usually pain or reflex sensations) from the internal organs, glands, and blood vessels to the central nervous system. [1] They are considered to be part of the visceral nervous system, which is closely related to the autonomic nervous system, but 'visceral nervous system' and ...
