Cerebral microbleeds are associated with accelerated cognitive decline. While in their activated state, microglia may serve a variety of beneficial functions.

Astrogliosis – Wikipedia, la enciclopedia libre

Although astrogliosis has traditionally been viewed as a negative response inhibitory to axonal regenerationthe process is gliosiis conserved, suggesting it has important benefits beyond its detrimental effects. Practically, PVM seem to be associated with severe consequences. The implications of gliosis in various neuropathologies and injury conditions has led to the investigation of various therapeutic routes which would regulate specific aspects of gliosis in order to improve clinical outcomes for both CNS trauma and a wide range of neurological disorders.

Gliosis is the universal response of the CNS to tissue injury and occurs as a result of many acute conditions such as trauma, ischemiaand stroke.

Gliosis has historically been given a negative connotation due to its appearance in many CNS diseases and the inhibition of axonal regeneration caused by glial scar formation. Gliiosis similar to Lin et al, they found a rather high prevalence — Gliosis has long been known as a characteristic of Alzheimer’s Disease ADalthough its exact role in the disease remains unknown.

PWM are also more common in persons with frequent syncope and orthostatic intolerance Kruit et al, Journal of Neuroscience Research.

Estos son algunos ejemplos de auras son:. Massive retinal gliosis MRG is a phenomenon in which the retina is completely replaced by proliferation of glial cells, causing deterioration of vision and even blindness in some cases. Beta blockers such as propranolol and related medications may be especially suitable to prevention of spikes in blood pressure. In its most extreme form, the proliferation associated with gliosis leads to the formation of a glial scar.

These definocion, notably IL-1, initiate an inflammatory response in various cells including astrocytes that contributes to the gliosis reaction.

Vascular processes include different types of small-vessel disease: These were subjects largely between 50 and There is confluence merging together so that there is a cloud surrounding the upper ventricles. Accessed July 31, This is the “stress is not good for you” connection.

Age is certainly the single most common association of PWM. This is presumably a “wear and tear” phenomenon.

Brain Gliosis & Homoeopathy

This process, which constitutes a form of gliosis known as microgliosis, begins within hours of the initial CNS injury. Still, in response, I have adjusted the language in some places to use more “academic” terms for reduced mental function.

Mayo Clinic Health Letter. There is an immense body of literature about white matter lesions, and here we are just discussing a small subset of these thousands of papers.


It is not clear if daily aspirin intake is useful or harmful in persons with PVM, and in our opinion, the decision should be made on an individual basis. Journal of the Neurological Sciences. This is basically a gliosks list of mostly rare conditions that has little practical consequences, but lets one know that there are many possibilities.


Deep white matter lesions are reportedly even more burdensome than periventricular white matter lesions to cognition Soriano-Raya et al, A few of the most important effects of astrogliosis are listed below.

Rather, therapeutic strategies for minimizing the contribution of astrogliosis to CNS pathologies must be designed to target specific molecular pathways and responses. Individuals with PVM lesions perform nearly 1 standard deviation below average on tasks involving psychomotor speed. In the authors experience, just a few days of extreme hypertension may be enough.

They commented that ” small punctate or focal WMHs are common in the brains of individuals in their 40s, and may represent an early stage of development of these lesions.

Treatment of the demyelinating diseases such as multiple sclerosis may be suitable, but is outside the scope of this brief review. PWM are often reported in persons with migraineand occur especially in women with migraine and aura. Accessed July 30, Unlike the microglial response, which occurs rapidly, the start of astrogliosis is often delayed.
