S4: Mild Behavioral Impairment. Assessment, biological and clinical factors in the cognitive impairment continuum
Published online by Cambridge University Press: 02 February 2024
Abstract
Mild Behavioral Impairment (MBI) is a diagnostic construct defined by the later-life emergence of persistent neuropsychiatric symptoms (for example, apathy, anxiety, depression, amongst others) displayed by older adults, with the aim to identify individuals at increasing risk of future dementia. The construct is also related to AD biomarkers including beta-amyloid, tau, and cerebral atrophy. For the assessment of MBI, researchers developed the Mild Behavioral Impairment Checklist (MBI-C) (Ismail et al., 2017) evaluating five domains: decreased motivation, affective dysregulation, impulse dyscontrol, social inappropriateness, and abnormal thought and perception.
The purpose of this symposium is to present four contributions that allow increasing our knowledge of the added value of MBI in clinical diagnosis of neurocognitive disorders.
Firstly, Dr. Maurits Johansson from Lund University (Malmö, Sweden) presents an overview of the role of MBI in the contemporary clinical diagnostic criteria for AD and some perspectives for treatment in the future.
Then, Dr. Sabela C. Mallo from the University of Santiago de Compostela (Spain) and Dr. Byron Creese from the University of Exeter (UK) will talk on methodological issues regarding the MBI-C, the underlying structure of the instrument and the impact of the self and informant ratings in the results of the questionnaire.
Dr. Martin Vyhnalek from the Faculty of Medicine of Prague (Czech Republic) will discuss the MBI profile and severity in a sample of β-amyloid positive individuals with amnestic Mild Cognitive Impairment compared to Cognitively Normal older adults.
Lastly, Dr. Camilla Elefante and Giulio Emilio Brancati from the University of Pisa (Italy) will analyze the relationships and boundaries between MBI and late-life major primary psychiatric disorders in patients who attend to psychogeriatric settings.
