Extra-severe craniocerebral injury should leave a varying degree of complications after waking up, for example, the intellectual level may not reach the normal state, fine and complex calculations may be very slow in response, or even unable to arrive at the results of the calculations, and the language function may be affected, for example, one can speak but cannot express the meaning of what he/she wants to say, and he/she can hear voices but does not understand the meaning of what others say, all of which are common complications. There are also limb sensory deficits. You may not be able to feel your hand when you stick it with a needle, and this loss of pain sensation is also possible. There is also poor limb movement and fine motor activity, and you cannot do needlework or chopsticks well.
