Hemiplegia does not have a total recovery but it can improve a lot if there is evidence of following the treatments and therapies recommended by doctors.
There are four kinds of hemiplegia:
Cerebral hemiplegia, spinal hemiplegia, facial hemiplegia and spastic hemiplegia.
Among the most common symptoms you can find: Loss of sensations in one half of the body, difficulty with motor activities, problems walking and maintaining balance, blurred vision, difficulty swallowing, numbness or tingling in one half of the body, etc.
Hemiplegia can be treated by a neurologist, neurosurgeon, or physical therapist.
The patient with hemiplegia is recommended to rest and control blood pressure. Then the treatment is based on discovering what the physical or psychological damage has been and minimizing the symptoms.

Recovery can take between 3 and 18 months.
