Abstract:

Introduction Behavioral and psychological symptoms of dementia ( BPSD ) , present in the vast majority of patients with Alzheimer's disease ( AD ) , cause extensive impairment in all areas , including functionality . Early diagnosis and management are critical , especially since these symptoms are not included in the Diagnostic and Statistical Manual of Mental Disorders ( DSM - V ) as a diagnostic criterion of AD , but only as specific features of some patients . The main purpose of this review is to highlight the importance of these behavioural and psychological symptoms of dementia , particularly in AD . In addition , we discuss why these symptoms have not been included in the latest DSM - V . Development We conducted a literature search through various databases to gather data about BPSD in AD , and found a total of 12 articles . Conclusions BPSD are present in almost all patients and result in cognitive and functional impairment . The prevalence of these symptoms varies depending on the study and the symptom in question . In our view , BPSD should be included among the DSM diagnostic criteria for AD .
