What Occurs in the Final Stages of PSP?

In the later stages of progressive supranuclear palsy, also known as PSP, symptoms include physical imbalance and body stiffness, making walking and other activities daily activities difficult, according to WebMD. Patients also have decreased vision that causes difficulty in maintaining eye contact or focusing on objects.

Progressive supranuclear palsy symptoms continue to worsen over time and typically become difficult to deal with after seven to nine years, states WebMD. Early-stage PSP symptoms include dizziness, occasionally resulting in falling down, stiffness in the body, the inability to walk, forgetfulness, and a loss of interest in previously enjoyable activities with family and friends. Patients may also display a change of personality as well as mental problems. Many times, patients have difficulty connecting with others or holding a simple conversation due to the slowing of the thinking process.

Progressive supranuclear palsy is a disease that causes the brain to deteriorate and affects the substantia nigra, reports WebMD. This disease is rare, and doctors often misdiagnose it as Parkinson's disease. To treat PSP, doctors prescribe a variety of medications to alleviate some of the symptoms. Those who have difficultly sleeping receive antidepressants, while Sinemet helps with uncontrollable shaking or tremors, claims WebMD. As of 2015, there is no known cure for PSP, and treatment only keeps the patient comfortable.
