What is cystic glial changes in the brain
When viewed from a structural perspective, all tissue of the spinal cord and brain can be divided into glial, neuronal and ependymal.
The most common is neural tissue composed of cells called neurons that produce a nerve impulse, and in support of direct transfer with extensive contact network of processes of such cells.
A dendrite is a process that transmits impulse directly to the cell, whereas the axon is the process of transferring the momentum directly from the body of the neuron to the dendrite of another cell.
As a rule, ependymal tissue is formed in a region of the brain ventricles and the Central canal of the spinal cord. The main functions of this tissue are considered to be development and the reverse process, the resorption of cerebrospinal fluid.
Whereas glial tissue consisted on the fact from ordinary connective-tissue elements, therefore, this fabric provides a complete supply of nutrients directly to the neurons responsible structural feature, in other words supports the neurons in the appropriate position and, in total, performs protective-barrier procedure for the basic cells in the region of the nervous system – the so-called neurons.
The reasons for the development of pathology
Glial changes in the brain represent the pathological proliferation of glial tissue directly. Causes symptoms gliosis are very diverse and to a greater extent provided by:
- Inflammatory diseases in the region of the brain;
- Demyelinating diseases of the brain (e.g. multiple sclerosis, acute encephalitis demielinizirute);
- Infarcts of the brain (stroke), intracerebral hemorrhage;
- Interventions in the area of the brain;
- Head injuries and trauma during childbirth, sometimes it forms a 4-6 month after birth will begin the replacement of neurons, glial cells directly, which in turn reduces the life expectancy of these children to two or three years.
Despite the fact that the causes of disease are completely different based on etiology of origin, they all share one property — as a result of glias leads to significant damage to the nervous tissue with a consequent reduction in the number of neurons with normal activity. In other words, glial changes in the brain represent a protective reaction of the organism, expressed as an attempt to create a barrier between pathological foci and healthy tissue.
As a rule, symptoms of glial changes is extremely varied and depends entirely on the size,location, number and reasons for the manifestation of glial lesions. In the case of massive brain damage due to surgery, intracerebral hemorrhage, traumatic brain injury, and brain infarction, are severe symptomatic manifestations of lesions of the nervous system.
In this case there is a neurological symptoms of deficiency kind, expressed as paralysis of the limbs, lowering of intellectual activity, impairment of understanding or pronunciation of speech with risks of total loss. Also often symptoms of epilepsy, due to the formation of the lesion cystic glial abnormalities of the brain, and the formation of block that prevents conduction of nerve impulses.
Eventually chronic pathological processes, expressed arterial hypertension, atherosclerosis of cerebral vessels, alcoholism, diabetes, you may experience are rather small foci of gliosis located, as a rule, diffuse.
At the earliest stages of the disease the main symptoms are considered frequent headaches, sleep disturbances and changes in mood. After a short period begin to show symptoms of impaired memory, decrease in intellectual activity, pathological tearfulness or irritability accompanied by increased aggressiveness, which together is called psycho-organic syndrome, as with defeat, which is formed for the purpose of diagnosis applied brain imaging methods, in other words, computer and magnetic resonance imaging. In case of conducting both types of studies can determine the size, location and the total number of cystic glial abnormalities of the brain.
However, in the case of the MRI will be much more clearly viewed small foci of pathology.In addition, there will be no x-ray radiation, which in the case of CT can reach twenty times the equivalent in comparison with conventional x-rays.
It should be noted that additional diagnostic methods are considered an ultrasound of the heart vessels by duplex scanning, study, so-called lipid spectrum of blood and determination of blood glucose, and in some controversial cases, the study of cerebrospinal fluid.
