Background
Progressive supranuclear palsy (PSP), also known as Steele-Richardson-Olszewski syndrome, is a neurodegenerative disease that affects cognition, eye movements, and posture.[1] PSP was first described as a clinicopathologic entity in 1964. Characteristics include supranuclear, primarily vertical, gaze dysfunction accompanied by extrapyramidal symptoms and cognitive dysfunction. The disease usually develops after the sixth decade of life, and the diagnosis is purely clinical. Currently, no therapy is proven to be effective.
Pathophysiology
- Pathologically, PSP is defined by the accumulation of neurofibrillary tangles in the brain.[2] Different rates and patterns of the accumulation of phosphorylated tau protein may account for the variation in clinical phenomena seen in patients with PSP.
- Liao and colleagues suggest that abnormal otolith-mediated reflexes may be at least partly responsible for the frequent falls in patients with PSP. They found that during near viewing, the translational vestibulo-ocular reflex responses in patients with PSP were, on average, only 12% of those of control subjects (p = 0.001). The amplitude of vestibular-evoked myogenic potentials was also significantly reduced in PSP patients compared with normal controls.[3]
Epidemiology
Frequency
United States
A population-based study in New Jersey by Golbe and colleagues revealed an overall prevalence of 1.39 cases per 100,000 population. The male prevalence was 1.53 cases, while the female prevalence was 1.23 cases (both figures are per 100,000 population); this finding was in accordance with a previously noted slight male preponderance. The adjusted prevalence ratio among patients older than 55 years was 7 cases per 100,000 population.[4]
Prevalence data derived from tertiary centers suggest that PSP affects 4-6% of patients with parkinsonism.[5]
International
Incidence has been assessed in Perth, Australia; crude incidence rates are 3-4 per million cases per year, approximately 5% of the incidence of Parkinson disease.[6]
Mortality/Morbidity
- PSP is usually fatal within approximately 6 years of onset, with a range of 2-17 years, based on cohort patients dying under surveillance; life table analysis among Golbe's entire cohort revealed a median disease duration of 9.7 years. Conflicting reports exist regarding the influence of age at diagnosis on survival; Golbe found a tendency for younger patients to survive longer, although this is not a uniform finding among other studies.[4, 7]
- The primary causes of death in patients with PSP are infections and pulmonary complications (eg, pneumonia) that are frequently related to immobility. Often, the primary morbidity relates to imbalance leading to immobility, although dementia, visual symptoms, and dysphagia are major concerns. Approximately 50% of patients with PSP require some aid to walk within 3 years of the initial symptoms. The usual interval from initial symptom occurrence to the need for a cane or a walker is 3.1 years, and the interval to confinement to a chair or bed is 8.2 years.[4]
Race
Most reported cases have been in whites. The affected cohort in Golbe's 1988 study was comprised entirely of white persons; however, the survey population included only 5.7% black individuals, thus preventing any meaningful analysis regarding race.[4]
Sex
PSP has a slight male predominance in most studies. According to Kristensen, the male-to-female ratio is 1.5:1.[8]
Age
The mean age at onset is approximately 63 years, with a range of 44-75 years.[4, 7] The median interval between onset and diagnosis is 3 years, with a range of 6 months to 9 years.
