Cognitive rehabilitation may provide short-term benefits for individuals with PCA, particularly in enhancing visuospatial and attentional skills, particularly in enhancing visuospatial and attentional skills.
Abstract
Objective
Posterior cortical atrophy (PCA) is a neurodegenerative syndrome primarily affecting visuospatial processing while sparing memory, language, and insight. The study aimed to evaluate the effects of a structured cognitive rehabilitation program on executive, attentional, and visuospatial functions in a patient with PCA.
Method
A 64-year-old male diagnosed with PCA underwent a 16-week cognitive rehabilitation program focused on visuospatial scanning, attention, and executive functions. Neuropsychological assessments were conducted at baseline (T0), immediately postintervention (T1), and at a 1-year follow-up (T2). Standardized measures were used to evaluate visuospatial abilities, attention, fluency, and learning, with performance changes analyzed across the three time points.
Results
At the end of rehabilitation, the patient demonstrated short-term improvements from baseline in visuospatial scanning, attention, verbal fluency, and learning. At the 1-year follow-up, cognitive gains were primarily maintained in auditory attention and learning/encoding tasks. Working memory and delayed recall remained stable over time, without significant gains. Notably, the patient reported subjective improvements in daily functioning and confidence in performing instrumental activities of daily living.
Conclusions
Cognitive rehabilitation may provide short-term benefits for individuals with PCA, particularly in enhancing visuospatial and attentional skills. The results emphasize the importance of ongoing, multidisciplinary, and adaptive interventions to sustain cognitive functioning and quality of life in PCA patients.

This case report supports further controlled clinical trials using functional connectivity guided rTMS in PCA and supports the hypothesis that intermittent theta burst, a form of rTMS, can modulate functional networks and improve associative memory in a patient with PCA presenting with memory impairments.

Abstract The dynamic modulation of large-scale network activity, which is inherent to cognitive processes, is disrupted in Parkinson’s disease. Subthalamic deep brain stimulation can either improve or deteriorate cognition, particularly executive function, with these effects often going unnoticed during acute parameter...

ABSTRACT Imagery-based cognitive training (CT) is a promising strategy for individuals with amnestic mild cognitive impairment (aMCI). However, there is a lack of studies investigating its differential impact in aMCI with and without amyloid pathology. Objective To investigate the effects of CT based on mental imagery...
