Brain death: when the brain stops working

Brain death is a condition that occurs as a result of damage to the brain that is incompatible with life. In this case, the brain stops functioning, resulting in the shutdown of all organs in the body and ultimately death.

The causes of brain death can vary: it can be a head injury, stroke, cerebral hemorrhage, infection or circulatory disorder. In any case, if the brain stops receiving oxygen and nutrients, its cells begin to die quickly, which leads to irreversible consequences.

Doctors use specific criteria to determine brain death. This usually occurs in cases where the patient has no reaction to external stimuli, there is no breathing and no heartbeat. If these symptoms continue for a certain time, then doctors may declare official brain death.

However, some people can remain alive in a state of brain death thanks to organ support. This occurs thanks to artificial ventilation and heart support using a pacemaker. In such cases, the body remains viable, but the person will not return to a full life.

Brain death is not only a tragic event for the patient himself, but also for his loved ones. In such cases, it is important to remember the need for emotional support and trusting communication to help cope with the loss of a loved one.

In conclusion, brain death is a serious and irreversible condition that occurs as a result of severe damage to the brain. Despite the possibility of maintaining the vital functions of organs, a person can no longer return to a full life. Therefore, it is important to remember the emotional support of loved ones in such difficult situations.

Brain death is a sudden, unexplained death caused by incompatible brain damage, associated with skull trauma, stroke, vascular diseases, infectious diseases, tumors. Typically, death occurs after the first or second week after the onset of the disease.

Clinically, several variants of lethal forms of cerebral insufficiency are distinguished. The differences between them are due both to the leading mechanism of development and the main focus of the lesion, and to the state of reactivity of different structural systems of the brain (Fig. 2).

1. Brain hemorrhages. They occur when microcirculatory vessels rupture, most often in places where their caliber changes (arteriovenous anastomoses, bifurcation sites, vascular loops). Characteristic is the development of grape-shaped, spherical, hemorrhagic cerebral infarction with the development of local dislocation changes, brainstem and respiratory disorders. Other vascular defects, especially those leading to hemorrhage and blockade of autoregulatory mechanisms, are dangerous because hypoxia through glia, which swells during pathology, leads to autoinfection and rapid tissue necrosis, the development of which is almost always spontaneous or traumatic intracranial hematoma accompanied by cerebral and focal neurological manifestations, degree which can be judged about the dynamics of the process, the state of compensation from other systems, and generally assess the patient’s condition. However, the dynamics of the clinical manifestations of cerebrovascular insufficiency alone does not allow one to determine the fate of the patient: even increasing focal symptoms do not always indicate impending death. Favorable dynamics in patients with intracranial hematomas (increasing protein-cell dissociation, inconsistent metabolic changes, etc.) does not predict an equally favorable outcome. Therefore, it is important to monitor all patients with acute cerebrovascular accident, regardless of their clinical condition.
