How people with amnesia learn new facts
New Semantic Learning in Patients With Selective Brain Lesions in Temporal Regions: a Behavioural and MRI Study
NA · University Hospital, Toulouse · NCT07191197
The researchers will try to see if people with amnesia from medial temporal lobe damage can learn new facts using memory tasks and MRI scans.

What this trial studies
This project will recruit a large group of adults with major memory impairment caused by non-degenerative bilateral medial temporal lobe lesions. Participants will undergo detailed psychometric memory testing alongside structural and functional MRI to map the brain networks engaged during new learning. The study will compare individuals who successfully acquire new semantic information with those who do not to identify clinical and cognitive predictors of learning. Results aim to clarify which preserved cognitive systems and brain regions support new learning and to guide cognitive rehabilitation strategies.
Who should consider this trial
Good fit: Ideal candidates are adults aged 18–70 with bilateral medial temporal lobe (hippocampal system) damage from non-degenerative causes who understand French, are affiliated with French social security, can consent, and can undergo MRI.
Not a fit: People with degenerative memory disorders, those with MRI contraindications, those who cannot understand French or lack French social security affiliation, or those outside the 18–70 age range are unlikely to be eligible or to benefit.
Why it matters
Potential benefit: If successful, the work could point to practical teaching methods and brain-based targets that help people with amnesia learn everyday facts more effectively.
How similar studies have performed: Prior case reports have shown that some people with amnesia can learn new semantic information using preserved cognitive systems, but large-group combined psychometric and neuroimaging studies are relatively uncommon.
