A 61-year-old woman with suspected schizophrenia has been attending an outpatient geriatrics service for some time, initially with memory complaints and panic attacks. During treatment, the diagnosis schizophrenia was rejected and psychopharmaceuticals were largely phased out, which improved cognitive functions. Eventually, flashbacks of incest experienced in childhood remained together with REM sleep pathology. The flashbacks, nightmares and the REM sleep pathology were responsive to rivastigmine. Rivastigmine use for the treatment of REM sleep pathology is known in the literature, but it has never been described previously that rivastigmine also impacts on flashbacks and nightmares..
