Brain ischemia and hypoxia after awakening, limbs are not controlled by the brain mainly because of ischemia, hypoxia lead to nerve and brain tissue damage. The brain is the center of control of human life activities, limbs are also controlled by the brain, and brain tissue to ischemia, hypoxia tolerance is low, hypoxia for about 5 minutes will lead to irreversible damage to brain tissue. When patients suffer from cerebral ischemia and hypoxia, the nerves in the brain and the centers controlling the movement of the limbs will be damaged, resulting in the limbs not being controlled by the brain, and even after awakening, the symptoms mentioned above may still occur. After waking up from cerebral ischemia and hypoxia, when the limbs are not under the control of the brain, the patient may often show symptoms such as convulsions, paralysis, numbness of limbs, etc. This kind of patients should go to the hospital in time for examination and treatment under the guidance of professional doctors.
