Do PSP patients hallucinate?

Could you please clarify for me if patients with PSP, or Progressive Supranuclear Palsy, experience hallucinations as part of their condition? I'm particularly interested in understanding if this neurological disorder is known to cause visual, auditory, or other types of hallucinations, and if so, what the nature and frequency of these hallucinations might be. Additionally, I'm wondering if there are any specific factors that may increase the likelihood of hallucinations occurring in PSP patients.
