Depending on the variant of the development of the disease and the clinical picture, the following types of hypotension of cerebral vessels are distinguished:
A normal outflow of venous blood in the brain region occurs when a person wakes up after a night's sleep. During relaxation, the veins relax, some blood accumulates in them. When a person rises from the bed, begins to move, his muscles contract, and the venous blood is pushed into the channel. This leads to an increase in the tone of the veins and a slight increase in blood pressure.
With venous hypotension, the head hurts in the morning. After some motor activity, the pain passes. The patient feels relatively good during the day. But closer to the evening there is a feeling of fatigue, a decline in activity, drowsiness appears, working capacity decreases.
The clinical picture of the disease is diverse. Some patients persistently pursue any one characteristic. Others have a number of symptoms.
In some patients, the head may be ill for several days in a row. Tablets do not help. Sometimes there is a dependence of pain on the time of the day, the work done, fluctuations in atmospheric pressure, overeating, overwork, etc.
Headache with excessive pulse stretching of the arteries is localized in the temples and crown, in the nape, has a pulsating character. When there is a violation of the outflow of venous blood from the skull, the head hurts in the nape of the neck. The pain has a pressing, growing character.
These manifestations are possible because of insufficient blood supply to the brain. As a result, oxygen starvation, lack of nutrients.
The weather change in patients with hypotension is reflected by irritability, an abundance of negative emotions, mood swings, depressive states, sleep disorders. Some can not get enough sleep, others suffer from insomnia.
Insufficient blood supply to the brain affects the patient's cardiac activity. The pain behind the breastbone appears in a state of complete rest. That is, it is not associated with either physical or mental stress.
Problems with blood supply to the brain lead to a violation of blood flow in the lungs. Patients often take deep breaths, yawn. For the same reason, they darken in the eyes, there are faints, "do not obey the feet" with a sharp change of position from horizontal to vertical.
The full functioning of many organs and systems depends on the normal functioning of the brain. Failures inside the cranium lead to malfunctions in the body.
