Unlike other tissues, the brain is most sensitive to a lack of nutrients and oxygen. Deficiency in blood supply (ischemia) provokes disorders of the central nervous system. This, in many cases, leads to severe disability and even death. That is why with any manifestations of disorders in the functioning of the central nervous system, immediate medical intervention is necessary.
The main causes of circulatory disorders include organic or functional vascular lesions. Often blood clots form in them, they are affected by atherosclerosis, spasms occur. In addition, lesions can occur as a result of head injuries, an infectious disease, intoxication, and others.
In addition to vascular pathologies of an acute nature, chronic failure also occurs. With this type of blood supply disturbance , a person’s memory suffers to a large extent , his intellectual abilities decrease, and motor and behavioral reactions deteriorate. Strengthening with age, such manifestations become a heavy burden for the patient and his relatives. Drugs that improve cerebral circulation have the ability to dilate blood vessels and inhibit platelet aggregation (gluing).
It should be noted that the main directions in the implementation of preventive and therapeutic measures is not only the use of vasodilators, medicines that prevent blood coagulation and platelet adhesion, but also nootropics and psychostimulants.
Drugs that improve cerebral circulation, with vasodilating properties, may have different mechanisms of action. It can be, for example, antispasmodics. However, their shortcomings include the lack of selectivity of action. In other words, acting on the vessels, expanding them, they along with this contribute to lowering blood pressure. This, in turn, can, on the contrary, lower blood supply.
That is why those drugs that improve cerebral circulation, which affect mainly the blood vessels, without significantly affecting the systemic circulation, are more interesting. Such properties are available in Cinnarizine, Nimodipine.
Considering drugs to improve blood circulation in the brain, it should be noted and such a tool as Vinpocetine. The medication has an antispasmodic effect, mainly expanding blood vessels. Along with this, it contributes to the normalization of metabolic processes in tissues, to a decrease in platelet aggregation. Thus, when it is used, microcirculation of blood in the vessels improves.
Xanthinol Nicotinate, Nicergoline are also drugs that improve cerebral circulation.
Blood supply disorders can be accompanied by asthenic and neurosis-like conditions. Their development is often noted due to head injuries. Therefore, psychostimulants can be used. These medications can increase the concentration of mediators and the activity of the central nervous system. However, their intake should be monitored by a doctor. Despite the fact that they contribute to improving mental and physical performance, with prolonged use, they cause irritability, insomnia, drug dependence, and anxiety.
Drugs that improve cerebral circulation can relieve symptoms. In particular, nootropics are prescribed to eliminate headaches and tinnitus (Encephabol, for example). These drugs that improve cerebral circulation can be of plant origin. For example, Tanakan has an effect at the cellular level, contributing to the normalization of metabolic processes.
