Methods and Results Five patients with PCA admitted in West China Hospital, Sichuan University from April to June 2021 were included. All of them showed spatial perception disorder, simultaneous agnosia, miscalculation, agraphia, structural apraxia, environmental agnosia. Apraxia of dressing and agnosia of left and right were found in 3 cases. One case had facial agnosia, visual ataxia and object perception disorder. Cerebrospinal fluid (CSF) biomarker determination: amyloid β-protein 42 (Aβ |
