Life From Vision in Alzheimer Disease

France80 participantsStarted 2004-12

Plain-language summary

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.

Inclusion Criteria: * Signed informed patient's or representative consent for the study * Patients over 50 years old * Patients whose bilateral visual acuity is less than 5/10, requiring cataract surgery * Patients suffering from Alzheimer's disease whose MMS score test is between 10 and 25 (10\<MMS≤25) Exclusion Criteria: * Patient's or representative's refusal * NEURO-ocular disease resulting in a severe vision impairment * Severe and evolving disease involving vital prognosis at short term

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Improvement score of the NPI (Neuropsychiatric Inventory). The improvement is based on the increase by 1 point on the score of NPI

Timeframe: 3 month after cataract surgery
