Table 3.

Proportions of participant groups with altered time awareness.

Temporal symptom	Controls	bvFTD	SD	PNFA	LPA	AD
	n = 32	n = 34	n = 17	n = 20	n = 9	n = 28
Ordering past events	0%	62%	12%	15%	56%	68%
Estimating intervals between events	0%	59%	18%	35%	67%	79%
Temporal rigidity	0%	41%	65%	35%	11%	11%
Clockwatching	3%	44%	59%	35%	22%	18%
Re-living past events	9%	59%	47%	25%	22%	21%

Data derived from the customized questionnaire (see text and Table 2) were used to calculate the prevalence of time awareness alterations in each participant group, summarized here as proportion (percentage) of the group showing an alteration (total group sizes shown above). All patient groups combined were significantly different from the healthy control group (p < 0.001 after correction for multiple comparison).
