Is Progressive Supranuclear Palsy (PSP) curable?

[Ashish_Chadda]

My mom is a 70-year-old female with a history of health concerns. I am reaching out regarding a series of symptoms that have been progressively affecting her over the past few years.
Onset of Symptoms:
At the age of 65, she began experiencing sprains and cramps in her legs, which was the initial indication of something not being quite right.
Progression of Symptoms:
Over the subsequent years, the symptoms progressed. At 67, her ability to maintain balance and walk properly significantly declined. She frequently falls backward when attempting to stand or walk, posing a risk to her safety.
Motor Symptoms:
Muscle stiffness and rigidity have become more noticeable, and she has difficulty coordinating eye movements. Her falls are often characterized by a backward motion.
Facial and Hand Symptoms:
Around the age of 68, her hands started twisting inward, and there are noticeable deformities in her facial muscles, specifically around her mouth.
Swallowing Difficulties:
At 69, she developed difficulties swallowing, which led to a narrowing of her esophagus. This has made it challenging for her to eat and poses a risk of aspiration.
Medical History and Diagnoses:
She has undergone initial medical evaluations, and the diagnosis provided is Progressive Supranuclear Palsy (PSP).
Is there anything that you can suggest or help
