Mep03-008	ASSOCIATION BETWEEN SLEEP REGULARITY AND SYMPTOMS OF ANXIETY AND DEPRESSION IN MIDDLE-AGED ADULTS
	Quote:	Conclusions Sleep timing regularity was more consistently associated with mental health outcomes, especially anxiety, than sleep duration variability. Maintaining regular sleep timing may support anxiety management in midlife, highlighting its potential relevance for preventive intervention.

Mpy03-022	Cross-sectional and longitudinal associations between sleep disturbances and psycho-affective symptoms in older adults: influence of amyloid positivity
	Quote:	Conclusions: In cognitively unimpaired older adults, associations between sleep disturbances and psycho-affective symptoms differ according to A#946; status. In A#946; individuals specifically, objective sleep fragmentation and instability are linked to psycho-affective vulnerability and brooding worsening over time. Sleep disturbances could thus represent early modifiable targets to mitigate psycho-affective symptomatology in older adults.
