Abstract:
Proper name anomia (PNA) is a common experience that can become unpleasantly amplified in people with Alzheimer's disease (AD). In this systematic review, we discuss the key cognitive stages where naming can fail: facial recognition, person-specific semantics, and proper-name retrieval. We examine claims that PNA is an early indicator of AD and review studies that have attempted to treat PNA in individuals with AD. Twenty-two eligible studies were included. The main findings are that individuals with AD frequently experience difficulties in recalling proper names at any point in the disease process, with the distribution of functional breakdown between the three key cognitive stages involved in successful naming being: facial recognition (19%), person-specific semantics (30%), and proper-name retrieval (40%). PNA can be an early manifestation of AD. Effective behavioural treatments are available for those whose naming difficulties occur at the retrieval stage, including trial-by-trial practice using vanishing cues and spaced retrieval. We also provide clinical recommendations regarding the diagnosis and treatment of PNA.

Amnesia
The severity and duration of memory loss vary depending on the type and underlying cause. Amnesia is classified into two main types: retrograde and anterograde.
Retrograde amnesia is marked by the loss of memories formed before the onset of the condition. Patients may recall distant past events but often forget those occurring shortly before the incident.
Anterograde...
