My mother is in late stages of progressive supranuclear palsy . She stays in bed most of the time, bp stays at 90/70 when it used to be 120 s/80 s, can t support her own weight, doesn t feel pain sensation, doesn t eat much, and doesn t talk much. Docs recently added clonazapam and seroquel for agitation and depression and she is a lot calmer. Could those meds be causing her to decline more or is it just the disease?
