What remains of a person when memory changes
Memory changes neither settle philosophical identity nor cancel dignity. Studies describe particular retained components; help and participation require respectful attention to the person.
Questions explored
Does a forgotten event stop belonging to a life?
Hume challenges that inference philosophically, without determining a particular memory problem’s cause.
Do the studies prove everyone has an immutable core?
No. They measured specified self-descriptions in particular groups with limitations.
Must memory be tested before respecting someone?
No. Dignity and essential help require no correct date or biography.
Must photographs restore memory?
No. Optional conversation is no prescribed treatment; refusal cancels no essential help.
Do all the traditions offer one answer?
No. The Gita and Hume disagree; similar images do not merge their teachings.
Does an adult with dementia become a child again?
Paul’s growing-up image establishes no such conclusion. Address the person as an adult.
Can sudden confusion wait?
It needs immediate medical help. Philosophical discussion and age do not replace contact.
Key distinctions
Personal identity and felt continuity are different questions. Philosophical criteria and psychological measurement cannot replace one another. (Bounded source use plus editorial reasoning; RESEARCH.md)

In Platel’s small brief study self-descriptions were stable, without significant enrichment of identity. The 2025 review describes some retained components; neither a universal immutable core nor a treatment follows. (Bounded source use plus editorial reasoning; RESEARCH.md)

Nostalgia’s association with continuity chiefly through narrative is bounded by samples and single-item measures; the first experiment had p=0.056. Storytelling is not a compulsory proof of dignity. (Bounded source use plus editorial reasoning; RESEARCH.md)
