Brief Summary

The overall objective of the study is to evaluate the improvement in patient-perceived quality of life following the use of the Paro robot integrated with traditional intervention in the elderly with dementia.

Detailed Description

The primary aim of this study is to evaluate the patient-perceived improvement in terms of quality of life through Quality of Life - Alzheimer's Disease (QoL-AD), following the use of the Paro robot, integrated with traditional intervention carried out within the IRCCS INRCA Alzheimer's Day Center. The Secondary aims are the evaluation of the improvement in cognitive status of the elderly person with dementia, in terms of orientation, attentional-executive, mnestic and visuospatial functions, detected through the Addenbrooke's Cognitive Examination (ACE-R); the assessment of mood improvement in terms of reduction of anxiety and depression, detected through the Rating Anxiety In Dementia (RAID) scale and the Cornell Scale for Depression in Dementia (CSDD); the assessment of the elderly person's acceptance of the technology through Quebec User Evaluation of Satisfaction (QUEST 2.0), semi-structured interview and analysis of physiological activation during interaction, with the Noldus Face Reader system and direct observation by the operator; the analysis of behavioral symptomatology through Neuropsychiatric Inventory (NPI); the assessment of practitioner's acceptance of technology through Technology Acceptance Model (TAM) and the assessment of job quality through semi-structured interview.

Intervention Type: Device

Intervention Name: PARO robot

Description: PARO is an advanced interactive robot. It allows the documented benefits of animal therapy to be administered to patients in environments such as hospitals and extended care facilities where live animals present treatment or logistical difficulties. PARO has five kinds of sensors: tactile, light, audition, temperature, and posture sensors, with which it can perceive people and its environment. PARO can learn to behave in a way that the user prefers, and to respond to its new name.
