Good morning everyone - my dad has been living with PSP for at least 10 years, having had experienced all of the 'usual' issues related to the condition. However, more recently he has been having 'shakes/shudders' which are distressing for him at times. Usually affects his throat as well as limbs. GP not sure what causes & has prescribed Diazepam on the advice of PD consultant, who made initial diagnosis of PSP. Has anyone else seen this with PSP?
