EpistemisParamnesia
Specialty: Psychiatry.
Why it occurs
- Korsakoff syndrome (chronic thiamine deficiency due to alcoholism, where confabulation fills memory gaps)
- Alzheimer or vascular type dementia
- Head trauma with frontal lobe injury
- Schizophrenia (delusions with real memory structure)
- Ganser syndrome (approximate responses or "pararesponse" of dissociative origin)
Initial workup
Detailed neuropsychological evaluation of memory (fixation, evocation) and frontal executive functions; Cranial MRI; serum thiamine (vitamin B1) levels; alcohol consumption screening.
red flags
Conspiracies that endanger the patient or their environment (e.g., false memories of having been attacked or robbed by immediate family members, leading to false complaints or extreme hostility).
Standard management
- Thiamine — essential at high doses early to prevent or stop the progression of Wernicke's encephalopathy to Korsakoff Syndrome
- Acetylcholinesterase inhibitors such as Donepezil — if the false memory falls within dementia
- Second-generation antipsychotics at low doses (if the paramnesias are integrated into an active psychotic delusional structure).
