[Unawareness of deficits in dementia and its impact on the caregiver-patient relationship: a literature review].

To date, few studies have focused on the impact of anosognosia on patients' and caregivers' daily lives. However, in more general studies, anosognosia has been linked to increased burden of family caregivers, refusals to receive care, and increased caregivers' psycho-behavioral disorders. However, these studies did not specify the nature of the impact of anosognosia on these manifestations, often attributed to cognitive impairment which is more representative of the disease. The aim of this review is to provide an overview of the current knowledge of the impact of anosognosia on the patient-caregiver relationship and to identify possible future directions to lessening its consequences.
