Abstract

It is well established that the clinical picture of dementias is not clinically homogeneous. For example, non-amnestic presentations of Alzheimer's disease have been referred to as a typical variant. Careful examination of clinical characteristics contributes to understanding the neurobiology of Alzheimer's disease and other dementias and may in turn enhance knowledge of the potential risk factors involved. 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 2019. Search terms used included dementia, déjà vu, zoophilia, pathological lying, and somatic symptom disorder. Publications found through this indexed search were reviewed for further relevant references. Uncommon/bizarre features of dementia were described as case reports and there were no systematic investigations.
