Behavioral and psychological symptoms and signs (associated with dementia), abbreviated as BPS(D), are polymorphous and frequent. They constitute a major difficulty for the patient, their relatives, and formal caregivers. They often respond favorably to therapeutic interventions. In spite of these observations, their clinical interest in early dementia is generally marginalized. However, they are frequent and sometimes prodromal or early, as evidenced by the concept of “mild behavioral impairment” (MBI). However, the nosological status of MBI is not definitively established. The delineation with early BPS or psychopathological comorbidities remains open. The etiopathogenesis of these disorders is likely to be complex and linked to both patient and environmental factors. Ontogenetic or developmental risk factors such as personality traits or attachment styles could also play a pathoplastic or vulnerability role for BPS or even dementia pathologies themselves.
