Neuropsychiatry: Frontotemporal dementia and young-onset dementias. Behavioral manifestations of neurodegenerative brain diseases as models for understanding mechanisms of cognition and psychopathology. Current focus is on apathy and its correlation with the evolution of cognitive impairment, functional decline and ultimately as a construct for approaching the study of rationale and emotive aspects of decision-making.
