Hypertensive brain disease is a more serious brain complication that occurs on a high blood pressure basis and is described in detail below:The definition of hypertensive brain disease refers to a series of clinical syndromes in which brain edema and intracircle pressure increase are the main manifestations of a sudden and sharp increase in blood pressure, exceeding the upper limit of the brain vessels ‘ own regulation, resulting in an overfilling of brain blood flow, leading to a passive expansion of the cerebrovascular environment and increased permeability. In short, the sudden increase in blood pressure has had an adverse effect on the brain, resulting in abnormal changes in its function and structure.Causes and conditions:• Pregenital hypertension: Patients who are themselves suffering from primary hypertension are prone to large fluctuations in blood pressure, which in turn causes hypertension in cases of irregular drug use, high emotional volatility, sudden discontinuation of pressure relief, etc.• Secondary hypertension: high blood pressure caused by diseases such as kidney hypertension (caused by kidney disease, e.g., nephritis, narrow kidney artery, etc.), endocrine high blood pressure (often due to chromosomal tumours, which release a large amount of tea phenolamine between them leading to a sharp increase in blood pressure), pregnancy hypertensive syndrome, which may also result from a sudden rise in blood pressure due to poor control of blood pressure or a change of condition.Epidemic mechanisms: Under normal circumstances, the cerebrovascular vessels have their own mechanisms for regulating and maintaining a relatively stable flow of brain blood within a certain blood pressure, by altering the ducts of the veins. But when blood pressure suddenly rises sharply and exceeds the upper limit of the brain vessels ‘ own regulation (generally constrictions exceed 180mmHg, and constriction exceeds 120mmHg, but individually there are differences), the cerebrovascular vessels are forced to expand, the close connection between the insides of the veins is destroyed, the vascular permeability increases, and the plasma elements seep out of the veins, resulting in brain edema formation; and, at the same time, the intracircle pressure increases, oppresses the surrounding brain tissue and affects the normal functioning of the brain, thereby triggering a series of clinical manifestations.The clinical performance of hypertensive cerebropathy is diverse and is reflected mainly in the following:Headaches are the most common and often the first symptoms. Pain tends to be more severe, often in the form of a full head swelling or throttle pain, the extent of which changes with blood pressure fluctuations, and when blood pressure rises, headaches tend to increase, and some patients even feel unbearable, seriously affecting normal life and rest.The mechanism for the creation of vomiting, which is often manifested in sprayive vomiting, is the result of increased internal pressure and the stimulation of the vomiting centre, which in turn triggers this more sudden and violent vomiting response, which is distinct from vomiting caused by general gastrointestinal disease.People with visual impairment can experience blurred vision, loss of vision, immediate blackout, and even short-lived blindness in serious cases. This is because hypertensive pressure causes pathologies such as convulsions, seepages and haemorrhages of the retina, which affect the normal functioning of the visual channel or of the retina itself, leading to visual anomalies.As the situation progresses, the level of awareness of the patients decreases. At first, it may be characterized as irritation, then as sleeping addiction, pretentiousness and coma in the event of serious illness. This cognitive impairment is mainly due to the high internal pressure of the skull and to the abnormal infusion of brain blood, which causes damage to advanced nervous centres such as the cortex of the brain, thus affecting normal awareness activities.Some of the patients with epilepsy have an epilepsy, which takes a variety of forms, ranging from a full-body spasm to an epilepsy. This is due to an abnormal discharge of the brain neurons, irritated by the insufficiency of blood, the insufficiency of oxygen and by adverse factors such as high intracircle pressure, leading to epilepsy.Other neurological symptoms can also be associated with a feeling of numbness and weakness, which affects normal physical activity; lack of clarity, which leads to communication difficulties; and a lack of co-habilitation, which results in poor physical balance coordination. These are the result of damage to different parts of the brain and the corresponding neurofunctional effects, which result in abnormality in physical exercise, speech and body balance.The clinical performance of different patients may vary, and these symptoms may occur simultaneously or sequentially, requiring timely medical attention if the symptoms are detected. Early identification, early medical treatment, early diagnosis, timely treatment and improved planning.
