Parkinson's disease is a progressively worsening neurodegenerative disorder of the nervous system, initially manifesting as bradykinesia, resting tremor, and other symptoms. As the disease progresses, the symptoms become increasingly severe. In the later stages, symptoms may include significant postural and gait abnormalities, such as obvious stooping and difficulty starting to walk, a phenomenon known as freezing, and turning around can also be difficult. Additionally, in the late stages, swallowing dysfunction may occur, leading to clinical signs such as coughing while drinking water and articulation disorders. Furthermore, individuals with Parkinson's disease are particularly prone to falling in the later stages due to impaired balance functions.
