Loss of cognitive neurological function is one of the manifestations of vegetativepatients. Vegetativepatient: The cortical function is severely impaired, and the victim is in an irreversible state of deep coma with loss of conscious activity, but the subcortical center can maintain voluntary respiratory movement and heartbeat, this state is called “vegetative state”, and the patient in this state is called The patient in this state is called “vegetative state”, and the patient in this state is called “vegetative person”. Except for some instinctive neural reflexes and the ability to metabolize substances and energy, the cognitive ability (including the ability to recognize one’s own existence) is completely lost and there is no active activity. It is also called vegetative state and irreversible coma. The brainstem of a vegetative person is still functional and can digest and absorb nutrients when they are delivered to his or her body, and can use this energy to maintain the body’s metabolism, including respiration, heart rate, and blood pressure. It can also produce some instinctive reflexes to external stimuli, such as coughing, sneezing and yawning. However, the organism no longer has consciousness, perception, thinking and other higher neural activities that are unique to humans. The EEG shows spurious waveforms. The vegetative state is different from brain death, which refers to the death of the whole brain, including the brainstem. In brain death, there is no voluntary breathing and heartbeat, and the EEG is a straight line. It is controversial whether to treat the vegetative state by providing various kinds of nutrition at high cost to maintain this state or to give up the maintenance of their life. How do you check for cognitive neurological loss? The patient is in a state of mute, with no conscious response to external stimuli and only the lowest level of vital functions such as respiration, nutrient metabolism and excretion and secretion, and certain reflexes such as light reflex, corneal reflex and pain avoidance. It can be classified as “coma” in Chinese medicine. At present, there is no effective solution for this disease at home and abroad. It is possible to use acupuncture and moxibustion to stimulate the meridians as appropriate. The recent onset of confusion, severe apathy, rigidity, or coma suggests dysfunction of the cerebral hemispheres, mesencephalon, and/or upper brainstem. Focal lesions of supratentorial structures can extensively damage both cerebral hemispheres and can also cause brainstem injury through severe cerebral edema that compresses hemispheric structures into the activating system of the mesencephalon and midbrain, causing brain herniation through the tracts of the cerebellar vermis. Primary subcerebellar (brainstem or cerebellar) lesions can compress or directly damage the reticular formation anywhere between the midbrain and the mesencephalon (via upward compression). Metabolic or infectious diseases can inhibit hemispheric and brainstem function through alterations in blood composition or the direct presence of toxins. Decreased cerebral blood flow (e.g., syncope or severe heart failure) or altered electrical activity of the brain (e.g., seizures) can also cause impairment of consciousness. Concussions, anxiolytic drugs, and anesthetics can cause impairment of consciousness without perceptible structural changes in the brain. Cognitive function is a complex process of mental activity. When a person’s cognitive function is altered, a number of changes occur, including thought, emotion, volition, and behavior. People with cognitive function deficits have specific personality characteristics, such as withdrawn, introverted, sensitive, illogical thinking, and fantasy. Some people call this a schizophrenic-like personality or schizophrenic-like latent qualities (or susceptibility qualities). And 50% to 60% of schizophrenia patients have schizoid susceptibility before the disease.
