Abstract: The present disclosure provides methods and compositions for treating fall-related symptoms in patients with neurodegenerative diseases such as Parkinson's disease or Parkinson-related diseases. In some embodiments, the disclosure utilizes nicotine or a salt thereof in combination of dopaminergic agent treatments for reducing fall-related symptoms such as reducing frequency of fall, reducing injuries related to fall, reducing severity of injuries related to fall, freezing of gait, improving posture stability, improving locomotion ability, improving balance and gait. In some embodiments, the methods predict fall frequency and tendency of recurrent falls in patients with Parkinson's disease, in particular, patients with typical Parkinson's disease.
