About

The aim of this study is to compare personality and social cognition changes, including emotion detection and self-awareness, and neuroanatomical correlates in patients, and how that affects the caregiver-patient relationship.

Full description

The purpose of this study is to understand social cognition changes in patients with Alzheimer's disease (AD), Parkinson's disease (PD), and Frontotemporal Lobar Degeneration (FTLD), which includes Progressive Supranuclear Palsy (PSP), Corticobasal Syndrome (CBS) and Frontotemporal Dementia (FTD - behavioural variant frontotemporal dementia, progressive non-fluent aphasia and semantic dementia), and the effect of these changes on the patients' relationship with their caregivers. In addition, the study aims to provide a greater clarity in the neuroanatomical correlates of social cognition in patients with FTLD, PD and AD.

Enrollment: 120 estimated patients
