After cerebral infarction (ischemic stroke) occurs, neurosensory and motor dysfunction often occurs, and the general rule is that movement is easier to recover than sensation, lower extremity is easier to recover than upper extremity, and limb function is easier to recover than speech function. In-depth analysis of the relevant factors affecting the recovery of damaged functions (sensory impairment, upper and lower limb paralysis, language impairment, swallowing difficulty, etc.) after cerebral infarction are roughly as follows.
I. Three relevant ratios
Ischemic necrotic foci, no matter what kind of tissue they occur in (such as brain and heart), the cells within the foci are not all dead at the same time, but are affected by different blood supply conditions, the presence or absence of collateral circulation, the physiological state of surrounding tissues and other factors. The presence or absence of collateral circulation often results in different numbers of cells surviving in the marginal zone (but unable to perform physiological functions due to low blood supply), while almost all cells in the core zone are dead. For this specific pathology, I have made the following three “proportional” analyses to influence the recovery of cerebral infarction.
1. Ratio between the marginal area and the core area within the necrotic focus
After cerebral infarction, due to the blockage of some blood vessels, the blood supply to the corresponding brain tissue is interrupted, thus causing ischemic necrosis of brain cells. However, since collateral circulation exists in most human tissues, brain tissue is no exception. The so-called core area refers to the area that is supplied with blood only by the blocked blood vessel without collateral circulation, so all brain tissues in this area die; the so-called limbic area refers to the area with collateral circulation, when the main blood vessel is blocked, there can still be a certain amount of blood supply and a certain amount of nerve cells in this area to maintain basic life, but cannot play normal physiological functions. Therefore, the larger the proportion of the limbic zone, the greater the chance of recovering the damaged function after the infarction;
2. The ratio of surviving cells to dead cells in the limbic zone
Although there is collateral circulation in the limbic zone, some cells are still alive and some are dead. Therefore, the higher the proportion of surviving cells in this area, the greater the chance of recovery of damaged functions;
3. The ratio of the functions of surviving brain cells to the damaged functions after the disease
There is a “division of labor” and “collaboration” between the functions of cells in each region of brain tissue. Brain tissue is morphologically divided into brain, midbrain, mesencephalon, cerebellum, medulla oblongata, and each region performs motor, sensory, language, thinking, and emotional functions, etc. The motor nerves are also divided into conscious, unconscious, and coordinated balance movements, and the sensory nerves are divided into superficial, deep, and proprioceptive senses. The motor nerves are also divided into upper limbs, lower limbs, trunk, and head; and the joint functions are also divided into extensor functions and stubborn functions. In a word, brain tissue manages various functions of the whole body and has a complex division into different “functional areas”. If the proportion of relevant functions in surviving cells corresponds to the functions lost after cerebral infarction is larger, the greater the chance of recovering damaged functions after cerebral infarction;
The basic conditions for the recovery of upper and lower limb functions
1.Keeping muscles from atrophy
2.Keeping joints from stiffness
In addition to the recovery of the corresponding motor nerve distribution area, the basic condition for the recovery of motor function is to ensure the normal muscle function (no atrophy) and normal joint function (no stiffness) of the corresponding functional area. To achieve these two points, the necessary muscle function health care treatment (such as human gong massage, electrical stimulation, etc.) and passive joint movement must be carried out before restoring the function of the nerve, so as to buy time and create conditions for the restoration of nerve function treatment later.
3.Blood supply status of affected limbs
In addition to insufficient blood supply to the heart and brain, patients with atherosclerosis often have insufficient blood supply to the limbs. In the treatment process, it is very important to pay attention to improve the blood supply to the affected limb to restore the function of the limb. Fortunately, when using traditional Chinese medicine to treat cerebral infarction, the blood supply to the limbs can be effectively improved while unblocking the cerebral blood vessels.
4.Proactive self-exercise
Medical practitioners and family members must warn patients that active, active and sufficient amount of voluntary exercise is quite necessary for the recovery of damaged functions of patients. Patients should be taught not to rely on the care of others and passive exercise, and not to regard the care and attention of others as “blessings”, thus developing the habit of “dependence”. It is because only persistent and conscious self-exercise can increase the amount of cardiac suspension movement, promote gastrointestinal peristalsis and enhance gastrointestinal function, and mobilize the anti-disease factors of the whole body.
Third, the conditions for the recovery of language function
1, the relevant language function area to restore blood supply;
2.Language training of nursing staff;
The above two are indispensable, especially language training must be serious and lasting, from simple to complex, step by step, persistent, in order to receive obvious results.
Fourth, the so-called “nerve cell activator” the use of the problem
The proper use of “nerve cell activators” does have a certain effect on promoting neurological recovery. For example, the proper use of nerve stimulants such as Strychnine (Western medicine) and strychnine (traditional Chinese medicine) is of certain significance in accelerating the recovery of nerve function (but under the guidance of a specialist, pay attention to safety and control the dosage).
V. Suitable living and care environment
Cerebral infarction is a chronic disease, which requires long-term conditioning to recover. The economic status of the family, the quality of caregivers, the literacy of the family, and the harmonious family atmosphere have a certain influence on the recovery of disease.
The organic and appropriate coordination of the above factors is the key to promote the recovery of cerebral infarction sequelae, and is also an important factor in analyzing and assessing the effectiveness of treatment.
