Diffusive changes in brain BEA

transmission of information in the human brain takes place through electronic impulses. Negative effects lead to violations of the signal. In the diagnosis, this may sound like a diffuse violation of brain BEA.Registration of electro potentials is carried out using an electroencephalogram.

What is EEG

neurons of all the structural formations of the brain emit electric potentials, which are recorded through electrodes placed on different areas of the head. The result is displayed on special paper in the form of several curved lines.

EEG reflects the functioning of individual brain structures in different states of a person. Neuroinfections, traumas, vascular pathologies and other conditions lead to diffuse changes in the brain. The method registers 4 types of waves:

1. Alpha waves are recorded in the majority of healthy people, their greatest activity is in the occipital and parietal areas.
2. The beta rhythm is also the norm, has a higher frequency than alpha. Increases when exposed to sensory organs, mental and physical activity.
3. Delta rhythm is typical for children of the first year of life, for adults only during sleep.
4. Theta waves are registered in children 1-6 years old, but can be in a dream in adults.

For analysis, determine the prevailing rhythm, its amplitude, symmetry of the two hemispheres. The presence of pathological waves, regularity of BEA is analyzed. If there are no changes, stimulation with light, sound, hyperventilation of the lungs is carried out, then the EEG is recorded again.

signs of abnormalities on EEG

Diffuse brain changes can be explained as the presence of EEG records conditionally normal brain activity without identifying pathology lesions. In other words, the potentials are already different from normal, but not pronounced.

If you study a particular tape with EEG recording, the diffuse changes of the brain bioelectric potentials will be shown in the following:

1. inhomogeneous conductivity.
2. Irregularly asymmetric signal.
3. Polymorphic polyrhythmic activity.
4. Pathological alpha, beta, delta, theta waves that exceed the norm.

The most pronounced changes in the last indicator. But for the conclusion "diffuse brain damage", one should note the fluctuation in all indicators. Deviations in several of them are observed in normal healthy people. Alcohol, drinks with caffeine, sedatives, fatigue and stress distort the EEG data and can manifest light diffuse brain changes BEA.Therefore, their possible influence is excluded 2-3 days before the study.

reasons

violations Moderate changes in the brain BEA observed under the following conditions:

• concussion and any head injury;
• vascular pathologies: atherosclerosis in the initial stages causes small deviations in progression - marked diffuse changes in brain BEA;
• after the transferred inflammation of the central nervous system;
• toxic effects, ionizing radiation;
• damage to the hypothalamus or pituitary gland leads to a concomitant disruption of the electrical potentials of the entire brain.

Often an unintended deviation in BEA is a sign of emerging epilepsy or a predisposition to it. When there are areas of increased activity, epileptic seizures should be expected.

Diseases and their symptoms

Before the development of pathology, the following symptoms are concerned:

• dizziness, headache;
• reduced performance;
• slowness, the complexity of rebuilding from one type of activity to a new one;
• inattention;
• decreased self-esteem, general retardation.

Specific diseases will be supplemented by specific signs. Diffuse brain trauma is accompanied by nausea, a single vomiting, loss of consciousness for a short period of time.

Symptoms of vascular disease that are associated with blood flow disturbances: dizziness, headache on the side of the lesion, attention and memory disorders, in severe cases - speech and writing pathology, perceptions, unexpressed plethysy of limbs.

Condition after infectious diseases of the brain for a long time may be accompanied by dizziness, weakness, rapid fatigue, stunned condition.

Toxic effects of poisons, alcohol for a long time after treatment will be accompanied by moderate diffuse changes in brain BEA.With prolonged exposure to a damaging factor, the effects can become irreversible. Disturbances in the conductivity of the signal, signs of damage to the reticular formation and the forebrain reflect a reduced overall functional activity of the central nervous system.

Short-term exposure to a large dose or prolonged exposure to small ones, leads to abnormalities in the EEG, which can often not be corrected by treatment, but can be slightly corrected.

Methods for improving the BAD

If deviations from the norm are recorded after recording the EEG, they must be eliminated as soon as possible. If you postpone the treatment "for later", then light changes will move into persistent and more pronounced, getting rid of which will not be possible. Therapy is long, takes from several months, maximum - a year. It is aimed at eliminating the cause that caused the development of pathology. Self-treatment in case of appearance of pathology of BEA can harm and lead to the neglected state of the disease!

Assign drugs to improve metabolism( Piracetam, Glycine, Sodium oxybutyrate, succinic acid, Cereburnorm).To protect the brain from metabolic products, use Mildronate, Vitamin E, Lamycatal.

Recommendations

It is useful to change the way of life, to be more outdoors, to dose physical exercise, to avoid stress, to get enough sleep, to give up bad habits. Nutrition should be balanced and correct, you need to consume enough animal protein, fruits and vegetables, reduce the intake of caffeine, which is rich in coffee and especially energy drinks. For children it is important to reduce the time of watching TV and staying at the computer. Some need to reduce the training load.
