Angioneuroses
Angineurosis is the general name for vascular diseases. Moreover, this is a disease “of nerves” and, moreover, very unpleasant. The disease develops due to disturbances in the nervous regulation of vascular tone. It manifests itself as pain and a feeling of coldness of the limb against the background of general warming of the skin.
The main role in the development of the disease belongs to excitatory processes in the cerebral cortex, amplified by histamine. The pathological process in angiovegetative dystonia is caused by the interaction of the inhibitory center of the cerebral cortex with its emotional arousal. Various types of stressful situations, somatic pathology, as well as hereditary predisposition are important. Therefore, if the patient’s relatives have cardiovascular diseases, the risk of developing angioneurosis increases.
**Forms of angioneurosis** Symptoms of angioneurosis depend on its form. The following forms are distinguished: 1. Cardialgic - pain in the heart area that occurs spontaneously; 2. Valict - pain (usually) under the right collarbone and “air” in the heart area; 3. Migraine - periodic headaches; 4. Neurogenic dysfunction of the digestive system - abdominal pain: the presence of asthenic and astheno-autonomic disorders in combination with pain during physical examination, arrhythmia; 5. Systemic scleroderma.
These and other forms may have different characteristics in terms of intensity and frequency of occurrence, but the basic clinical picture is approximately the same. The main feature is its paroxysmal nature (similar to a vegetative crisis in the paroxysmal form of heart rhythm disorder).
The vessels of the brain include: cerebral blood vessels containing arterial and venous blood; the brain barrier for this reason is highly permeable. This determines the high functional activity of cerebral vessels and a rather sharp fluctuation in their tone under various emotiogenic influences. The sensitivity of cortical neurons to them lies in the ability to change the ratio between the nerve impulses arising in them. An important role is played by its reactivity and plasticity, i.e. the ability of cortical centers to compensate for the impaired function of internal
