The occurrence of CS among early-onset Alzheimer\u2019s disease (EOAD) is extremely rare. We describe a case in which the unrecognition of CS as part of EOAD resulted in a wrong psychiatric diagnosis and inappropriate treatment. This paper aims to acknowledge CS as an early or core manifestation and highlight EOAD as a differential diagnosis of mental disorders in young people, even without a remarkable family history.<\/jats:p>","DOI":"10.3233\/jad-215565","type":"journal-article","created":{"date-parts":[[2022,3,4]],"date-time":"2022-03-04T13:54:29Z","timestamp":1646402069000},"page":"155-160","source":"Crossref","is-referenced-by-count":2,"title":["Capgras
