Hand numbness after cerebral infarction can be fully recovered in some patients within two weeks, while some patients need several months, and even some patients still have symptoms of hand numbness after one year, which is generally called the sequelae period and depends mainly on the site of infarction. For patients with cerebral infarction in the basal ganglia area, if the lesion damages the internal capsule, patients generally have poor recovery of symptoms and signs, and most of them may have sequelae, such as possible hand numbness and other sequelae. For patients with large cerebral infarction, they may also have the sequelae of hand numbness, and they may also have other sequelae, such as motor impairment of the lateral limbs, speech dysfunction, some of them may also have consciousness impairment, and some patients may have a decorticated state or a vegetative state, etc.
