Brainwave cerebral asymmetry - what is it? Causes, symptoms, diagnosis and treatment of the disease
The brain is considered a complex structure. Therefore, various diseases do not bypass it. Some respond well to therapy and have little to do with human life, others require closer attention from doctors. One of the most common pathologies is lateruroentriculo-asymmetry of the brain. What it is?
The main components of the brain are 4 ventricles. They are represented by small cavities. They constantly produce and circulate the cerebrospinal fluid - cerebrospinal fluid. Its main purpose is to transport nutrients to the cells and to remove the products of vital activity. In addition, the cerebrospinal fluid plays a kind of cushioning role when striking the head.
Normally, each of the ventricles contains about 150 ml of cerebrospinal fluid. Three times a day it is completely renewed. An increase in its volume provokes an increase in the size of the ventricles, a change in their shape. When the lateral C-shaped curvature disappears, the cavity becomes round. In this case, they ta
What is it? Under such a terrible diagnosis is understood a violation characterized by an asymmetric change in the size of the ventricles. To a small extent, such changes are not considered pathology. However, a noticeable progression can lead to severe brain disorders. Enlarged ventricles begin to press on surrounding elements and structures, provoking a disruption of the functioning of neurons. In some cases, death of nerve cells is observed.
Causes of the development of the
abnormality Pathology can both be congenital in nature and be the result of other health problems. In infants, laterurentriculo-asymmetry is more common than in adults. Approximately every 500th newborn is diagnosed with an increase in the size of the ventricles, and in 80% of cases it is due to congenital disruptions in the development of the brain. For the remaining 20%, birth trauma occurs. In a child, intrauterine anomalies may appear due to problems with the health of a woman during pregnancy. We are talking about such diseases as toxoplasmosis, rubella and mumps.
The causes of cerebral latententericulosymmetry in adults differ somewhat. To provoke an increase in cerebrospinal fluid and, as a consequence, ventricular size can:
- trauma to the skull;
- transferred neuroinfections( eg, meningitis);
- tumors, cysts, hemangiomas;
- cerebral thrombosis.
Accurate determination of the cause of outflow and excessive production of cerebrospinal fluid allows the appointment of an effective treatment.
Clinical picture of
Moderate cerebral latencyrikulosymmetry does not affect a person's condition. The development of the pathological process can be said in the presence of pronounced changes in the lateral ventricles. In this case, the patient feels the symptoms of the primary disease, which provoked laterurentriculo-asymmetry. It can be a violation of sensitivity, memory, coordination or thinking. Usually the patient complains about:
- headaches, a feeling of squeezing and buckling;
- nausea and vomiting, especially in the morning;
- state of anxiety.
The patient is constantly accompanied by apathy, drowsiness. Such symptoms of cerebral laturentriculo-asymmetry indicate that the pathology is progressing. As a result of disturbed outflow of cerebrospinal fluid, pressure on the brain increases, which leads to:
- oculomotor disturbances;
- development of dementia;
- vision impairment;
- urinary incontinence;
- impaired motor function( gait becomes uncertain).
If treatment of the anomaly does not begin in time, it can take a chronic form.
Course of the disease in children
The manifestation of the pathological process in young patients depends on age. Children are usually capricious, poorly eaten. The view is directed downward, but the eyes are too wide open. In children, the bones of the skull differ in compliance and plasticity. Therefore, violations can occur in an increase in the size of the head. Often observed pulsation of the fontanel, swelling of the veins.
Children of school age also suffer from cerebral laturentriculo-asymmetry. What it is for the disease - only know a few. Its development can be preceded by congenital disorders of brain formation or failures at the genetic level. At this age, the disorder manifests itself:
- divergence of the seams between the bones of the skull;
- slow development;
- excess weight;
- sharp mood swings;
- a violation of the ability to move the eyeballs;
- problems with mental activity;
- reduced affection for loved ones.
In adolescents, this disease is the result of craniocerebral trauma or transmitted infections. It is accompanied by severe headaches, vomiting and nausea, convulsions. Are not excluded and psychosis.
To prescribe treatment and tell what brain cerebral latencyrikulosymmetry is the specialist's tasks. When symptoms of a disorder appear, you should immediately consult a therapist. After studying the clinical picture and complaints, the doctor will send to a neurologist. It is this specialized specialist who can confirm the preliminary diagnosis. To this end, the patient is assigned a comprehensive examination, which consists of the following activities:
- CT, MRI.These methods are considered the most informative. With the help of tomography, you can assess the condition of the ventricular system, determine the causes of the outflow of cerebrospinal fluid.
- Inspection of the fundus.
If the listed variants of diagnosing cerebral latenterentulo-asymmetry give conflicting results, a lumbar puncture is prescribed. The results of the analysis of cerebrospinal fluid can accurately determine the causes of deformation of the lateral ventricles.
Treatment of cerebral laturenrikulosymmetry with drugs is prescribed only with a pronounced clinical picture. The main direction of such therapy is the elimination of the underlying disease, which provoked a change in the size and shape of the ventricles. For this purpose, the following groups of drugs are recommended:
- Vascular tools.
- Nootropic drugs.
- Sedative medicines.
- Anti-inflammatory drugs.
All medications, as well as their dosage are selected individually.
Need for surgical intervention
When conservative therapy is ineffective, an operation is prescribed. A puncture is performed in the place of the greatest accumulation of cerebrospinal fluid. If the cause of squeezing the outflow of cerebrospinal fluid is a tumor, it must be removed.
In modern medical practice, ventricular bypass surgery has been widely used in the treatment of latenterentulo-asymmetry. During the procedure, the doctor establishes a shunt with which the cerebrospinal fluid begins to enter the bladder. After the operation, the patient can return to the usual rhythm of life. Intracranial pressure gradually decreases, and the remaining symptoms of malaise disappear. Unfortunately, shunting in half the cases with time loses its effectiveness. It does not exclude the development of complications, including inflammation of the soft tissues and attachment of a secondary infection. In this case, a reoperation with a shunt replacement is required.
A common question that almost all patients diagnosed with cerebral laturentriculo-asymmetry are asking specialists for: Is it dangerous? It is not possible to answer it unequivocally.
If there is an unexplained form of the disease, when changes in the lateral ventricles do not cause discomfort to the patient, no specific therapy is required. It is enough just to observe the anomaly. In the case of a progressive disease, treatment is necessary. It can be both medicamental and surgical. If you ignore the manifestations of the disorder and do not seek help from a doctor, the probability of complications increases. In addition to impaired consciousness and motor function, such a patient is threatened by a coma.
