BACKGROUND: Four-repeat (4R)-tauopathies cause variable clinical profiles leading to clinical misdiagnosis. While sex differences are reported in Alzheimer's disease (AD), Lewy body disease (LBD), and clinically-defined frontotemporal dementia (FTD), little is known in 4R-tauopathies.
METHODS: National Alzheimer's Coordinating Center data were used for pathologically-defined 4R-tauopathies: progressive supranuclear palsy (PSP, n = 175), corticobasal degeneration (CBD, n = 114), argyrophilic grain disease (AGD, n = 230), Other-4R (n = 67). Sex differences for clinical presentation and co-pathologies were assessed adjusting for age and multiple comparisons.
RESULTS: Most common clinical diagnosis was PSP (41%) for PSP; unspecified FTD (36%) for CBD; AD for AGD (57%) and Other-4R groups (48%), without sex differences. Females had less cognitive decline, apathy, motor symptoms; were older at cognitive, behavioral change onset. Males were more likely to demonstrate LBD co-pathology and clinical profile.
CONCLUSION: Both females and males have low clinical diagnostic accuracy for 4R-tauopathies. Females with 4R-tauopathies may experience less severe clinical presentations and less co-pathology.
