The VIVA study is focused on Alzheimer's disease patients with a low vision due to a bilateral cataract. The aim is to study cataract surgery results on patients' autonomy, behaviour, and mood. In fact those dement elderly patients suffer from a progressive loss of superior functions, with loss of autonomy, behaviour and mood degradation, associated with physical disabilities. The work hypothesis is that a loss of sensorial functions, particularly visual, is an aggravating factor of NEURO-cognitive troubles and absence of communication with outside circle. The protocol consists in investigating superior functions, autonomy, and behaviour troubles of the participating patients, with the help of a series of neuropsychological tests used one month before and three months after cataract operation on the eye with the worst vision. Independently of the study, patients must have given an informed consent to cataract surgery. Their participation lasts 4 months+/- 1 month. The aim of the study is to evaluate whether the cataract surgery improves patients' behaviour, autonomy and mood and possibly to show evidence onf drawbacks in of such a practice.The main objective targets to cataract surgery benefice on patients suffering from both Alzheimer's disease and impeding cataract, aiming to improve behaviour troubles. The specific objective is to measure this benefice in correlation with visual acuity improvement.

Primary Outcome Measures:
  • Improvement score of the NPI (Neuropsychiatric Inventory). The improvement is based on the increase by 1 point on the score of NPI [ Time Frame: 3 month after cataract surgery ]

Secondary Outcome Measures:
  • Improvement score of MMS(Mini mental status), of ADAS-COG(Alzheimer disease Assessment scale for cognitive function), IADL(Instrumental activity on daily) and GDS(Geriatric depression scale). [ Time Frame: 3 month after cataract surgery ]

Enrollment: 80
Study Start Date: December 2004
Study Completion Date: April 2011
Primary Completion Date: March 2011 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Patients suffering from both Alzheimer's disease and low vision due to a bilateral impeding cataract.
Behavioral: Questionaries
MMS (Mini Mental Status), ADAS-cog Alzheimer Disease Assessment Scale for cognitive functions, NPI (Neuropsychiatric Inventory) for behavior troubles, IADL (Instrumental Activities of Daily) for autonomy evaluation, GDS (Geriatric Depression Scale) or Cornell Scale (Cornell Scale for Depression in Dementia) for mood troubles.
