Abstract:
In the past decades, clinicians have recognized that dementia may appear as atypical or variant syndromes, as well as the typical form. This study aimed at describing uncommon or bizarre symptoms/syndromes observed in patients suffering from dementia. Medline and Google scholar searches were conducted for relevant articles, chapters, and books published before 2017. Search terms used included delusional jealousy, delusion of pregnancy, dementia, erotomania, folie à deux, and lycanthropy. Publications found through this indexed search were reviewed for further relevant references. The uncommon symptoms/syndromes were described as case reports and there were no systematic investigations.
