We used the Uniform Data Set Version 3 Neuropsychological Battery (UDS3-NB), which possesses normative data for the Peruvian population, to assess global and specific cognitive functions.

The most common initial clinical symptom was parkinsonism (55.9%), followed by postural instability (23.5%) and dementia (20.6%). Our cohort showed poor performance on global cognition, with selective impairment of processing speed, executive function, and episodic memory. Attentional and visuospatial skills were mildly affected, with partial preservation of naming. There was no significant relationship between the initial clinical symptoms and global cognition, except for a slight correlation between parkinsonism and visuospatial function (r\u2009=\u20090.18; p\u2009&lt;\u20090.05).<\/jats:p>\n                  <jats:p>We found that PSP patients in Peru had extensive impairment in executive function, processing speed, and episodic memory, with relatively preserved naming, consistent with other international cohorts. We did not find a correlation between initial clinical signs and cognitive profile, suggesting that an interdisciplinary approach is needed to evaluate patients with suspicion for PSP. Longitudinal studies are needed to more clearly define the progression of neuropsychiatric symptoms in PSP patients.<\/jats:p>","DOI":"10.1055\/s-0046-1824433","type":"journal-article","created":{"date-parts":[[2026,6,23]],"date-time":"2026-06-23T23:35:05Z","timestamp":1782257705000},"page":"001-009","source":"Crossref","is-referenced-by-count":0,"title":["Cognitive
