Subjective time perception in dementia: a behavioural and neuroanatomical analysis.

ABSTRACT: Subjective time perception-the modulation of elapsed clock time by sensory, homeostatic and psychological factors-is fundamental to how we experience the world. People with Alzheimer's disease and frontotemporal dementia often exhibit clinically relevant symptoms of altered temporal awareness but these are poorly understood. Here we addressed this issue in a cross-sectional, case-control study of 60 patients representing all major Alzheimer (n = 24) and frontotemporal (n = 36) syndromes [mean age 68.8 (range 48-77 years); 28% female] and 24 cognitively well age-matched controls [age 69.4 (6.5) years; 50% female]. Subjective duration perception was assessed using an auditory temporal bisection paradigm, in which the task was to compare sound stimulus durations with learned (2
