Hippocampal Sclerosis and Amnesia Not Due to Alzheimer's Disease

France141 participantsStarted 2016-01-27

Plain-language summary

Hippocampal Sclerosis (HS) leads to anterograde amnesia mimicking early Alzheimer's disease (AD) (so called HSA-nonAD). Recent studies showed that (a) the deficit of episodic memory as well as the level of hippocampal atrophy in bvFTD may be of similar severity to that observed in AD, even at initial presentation, leading to misdiagnosis in 22% of cases with post mortem diagnosis; (b) amnesia with HS due to microvascular lesion and microinfarcts can also cause impairment of episodic memory mimicking AD, without subcortical cognitive profile. Because these diseases involve distinct pathophysiological processes, they require different specific care and treatment. In consequence, it is very important to improve our knowledge about HS in order to identify its mechanism and improve the diagnosis.

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.
