Whether a 90-year-old man can recover from hemiplegia after a stroke depends on his condition, the degree of sequelae, and whether the rehabilitation treatment is effective, but the recovery is usually worse than that of a young man. 1. Condition: at the age of 90, the condition of the elderly after a stroke is generally more critical, if the location of cerebral infarction or cerebral hemorrhage is very dangerous, for medium to large cerebral infarction or cerebral hemorrhage after treatment, hemiplegia and other symptoms will still remain difficult to recover. 2. Degree of sequelae: If the sequelae of hemiplegia are more serious and accompanied by other underlying diseases and complications, it will be difficult to recover. If the symptoms are mild and the disease is single, you can try to take medication or acupuncture and other ways of treatment, such as stroke rejuvenation tablets, tonifying the sun to restore the five soups and other drugs. 3. Rehabilitation therapy: After a stroke, if the patient is actively engaged in rehabilitation therapy at an early stage, there is a possibility of recovery, such as acupuncture, physical rehabilitation, operational rehabilitation, etc., and take medication as prescribed by the doctor. Families of hemiplegic elderly with limited mobility should pay attention to them, conduct regular checkups, take medication regularly as prescribed by the doctor, and actively carry out rehabilitation treatment.
