The cause of lacunar dementia is a variety of diffuse vascular diseases of the brain. non-stroke course of atherosclerosis and hypertension, diabetic microangiopathy, damage to systemic vessels due to collagenosis. Changes in the state of the blood supply to the brain (improvement of the rheological properties of blood, taking vasodilators) can cause fluctuations in the condition and short periods of some improvement in these patients. There is a certain type of neuroendocrine tumors - carcinoids, which release certain hormones into the blood (most often serotonin, prostaglandin, histamine and others). Due to the entry of these hormones into the blood, a person develops carcinoid syndrome, which is characterized by certain symptoms.
As is already clear from the definition of pathology, the reasons for the development of carcinoid syndrome lie in the presence of a neuroendocrine tumor in the patient�s body. Fortunately, these tumors grow very slowly, so if the pathology is detected at an early stage, a complete cure or prolongation of a person�s life by 10 years or more is possible. Therefore, it is so important to undergo regular examinations and pay attention to any suspicious symptoms that may indicate carcinoid syndrome - a sign of cancer in the body.
