    ### Instruction:
    Is progressive supranuclear palsy inherited ?
    ### Response:
    Most cases of progressive supranuclear palsy are sporadic, which means they occur in people with no history of the disorder in their family. However, some people with this disorder have had family members with related conditions, such as parkinsonism and a loss of intellectual functions (dementia).
