Cerebral infarction usually refers to cerebral infarction, and leg weakness is a sequela of cerebral infarction.
Cerebral infarction is a disorder of blood circulation in the brain, and the reason why weakness occurs after cerebral infarction is mainly due to the necrosis of innervating cells of the cerebral infarction patient, which leads to poor innervating function or loss of innervating function, and then there will be the symptoms of weakness in the legs.
In layman’s terms, this means that the nerves in the brain that give out instructions are abnormal.
In addition, after cerebral infarction, there may be a decrease in the motor function of the whole body, which may also lead to a decrease in the strength of the lower limbs.
For cerebral infarction, the onset of the disease is usually more acute, and the symptoms will reach a peak in a few seconds or minutes, so when the patient has symptoms such as hemiplegic aphasia, transient dizziness, limb weakness, etc., he/she needs to consult the doctor immediately, and must not delay the condition, so as not to cause serious consequences.
