What are the dangers of stroke ? This is the first question that many patients think of. Stroke is a very harmful disease. Because the patients themselves do not understand the disease, they are harmed by it. So, what are the dangers of stroke?
Harm of stroke 1. Hemiatric Sensory impairment
This symptom is something that patients with stroke need to focus on prevention and treatment, otherwise the patient will lose their ability to perceive. Hemi-sensory disorder refers to the impairment of pain, temperature and proprioception on one side of the patient's side.
The nerve fiber that conducts pain and temperature sensation goes from the skin receptor to the nerve ending to the dorsal horn of the spinal cord, crosses to the contralateral lateral funiculus and ascends, and passes through the posterior branch of the internal capsule to the sensory center of the postcentral gyrus of the cerebral cortex. The sensory center comprehensively analyzes the incoming stimuli to determine whether they are hot, cold, or painful. If the internal capsule is damaged, the conduction of pain and temperature sensation in the contralateral hemisphere will be interrupted, so pain and temperature sensation will be impaired.
Harm of stroke 2. Hemiplegia
This hazard will cause half of the patient's body to be unable to move freely, seriously affecting the patient's life and causing a particularly severe mental blow. The nerve fibers that control the voluntary movement of and are called pyramidal tract .
This tract is a fiber sent from the brain pyramidal cells in the precentral gyrus of the motor center of the cerebral cortex. It goes down through the internal capsule to cross at the lower end of medulla oblongata , to the corresponding anterior horn cells of the spinal cord on the opposite side, and then sends out fibers from the anterior horn cells to innervate skeletal muscles. . For example, when the internal capsule bleeds, the damaged pyramidal tract is above the intersection plane, so paralysis occurs on the contralateral side of the lesion, resulting in contralateral side, tongue, and limb paralysis.
How to check the sequelae of stroke ? The following examinations can be done to confirm the diagnosis:
1. Brain CT scan: The diagnostic rate of brain CT for hemorrhagic stroke is 100%, and the diagnostic rate for ischemic stroke is more than 85%.
2. Measurement of blood sugar, urine sugar and : The treatment and prognosis of stroke patients are closely related to whether they have diabetes.
3. Hemorrheology examination: Hemorrheology is a science that specializes in studying the deformation laws of blood and its components.
4. Eosinophil count: The number of eosinophils varies depending on the condition.
5. lumbar puncture cerebrospinal fluid examination: lumbar puncture examination cerebrospinal fluid is of great significance for clarifying the nature of stroke.
6. blood lipids : The blood lipids related to stroke are mainly triglycerides , cholesterol, β lipoprotein , etc.
7. Other auxiliary examinations: In addition to the above examinations, cortical evoked potentials, cerebral blood flow measurement, Doppler ultrasound, brain topography, levels of various trace elements, hormone levels (such as T3, T4), etc., are useful for Stroke also has varying degrees of reference value.
