Parkinsons disease PD is a degenerative disease of brain, which is characterized by slowness of all movements, stiffness of limbs, tremors of hands feet, and imbalance. It continues to progress in severity, as there is no medicine to cure this disease. However, there are several good medicines available to make a patient with PD better. You should consult a good neurologist to get her evaluated and adjust her medications. In some cases, deep brain stimulation surgery may be beneficial. Best wishes, Chat Doctor.
