Progressive supranuclear palsy (PSP) is a late-onset neurodegenerative disease involving the gradual deterioration and death of specific volumes of the brain. [1] [2] The condition leads to symptoms including loss of balance, slowing of movement, difficulty moving the eyes, and cognitive impairment. [1]
PSP has been all over the news—here's what to know about it.
Parkinson-plus syndromes are usually more rapidly progressive and less likely to respond to antiparkinsonian medication than PD. [10] [11] However, the additional features of the diseases may respond to medications not used in PD. [citation needed] Current therapy for Parkinson-plus syndromes is centered around a multidisciplinary treatment of ...

The applause sign was first described by Dubois and colleagues in 1995, as “a simple test of motor control that helps to differentiate Progressive supranuclear palsy (PSP) from frontal or striatofrontal degenerative diseases”, [1] but has since appeared in various neurodegenerative conditions involving frontal lobe dysfunction.
Eventually, mutism and progressive dementia set in. [2] Parkinsonism can be the first symptom of the disease, and it is noteworthy that some FTDP-17 patients have been misdiagnosed with Parkinson's disease or sporadic progressive supranuclear palsy. However, in some families, the parkinsonism appears later in the progression of the illness or ...
Progressive supranuclear palsy (PSP) is a type of tauopathy, but the cause is not yet discovered. For PSP unusual phosphorylation for tau protein causes vital protein filaments in the nerve cells to destruct, a phenomenon called "neurofibrillary" degeneration.
Progressive supranuclear palsy (PSP) without CBD is estimated to be ten times more common. CBD represents roughly 4–6% of patients with Parkinsonism. Average age at disease onset is about 64, with the youngest confirmed onset being at age 43. There may be a slight female predominance. [16]
