The cortisol awakening response predicts a same-day index of executive function in healthy young adults
Law et al.
The finding, in our words
The magnitude of the cortisol awakening response, measured from self-collected saliva at home, positively predicted performance on an attention-switching task later the same day in healthy young adults. The association held only when sampling occurred within eight minutes of waking, demonstrating that precise electronic timing verification is essential for valid decentralised saliva-based cognitive biomarker studies.

This study used home self-collected saliva samples to successfully monitor cytokines and cortisol in mothers and infants, finding that a community singing intervention significantly reduced salivary interleukin-6 levels in mothers with postnatal depression.

At-home saliva sampling for cortisol was feasible over 12 days in two people with poststroke aphasia, with the cortisol awakening response remaining consistent across days and weeks.

This study found that salivary 11-dehydrodexamethasone correlates strongly with serum dexamethasone, unlike salivary dexamethasone which shows poor agreement. This validation suggests patients could self-collect saliva samples at home to verify dexamethasone absorption for the overnight suppression test.

This study validated a lateral flow fluorescence assay using quantum dots for saliva and europium nanoparticles for serum to detect cortisol within physiological ranges. The test operates in 15 minutes with a handheld reader, supporting point-of-care and at-home monitoring without a cold chain.

The study determined that an at-home saliva collection protocol using the passive drool method was feasible for Black women with histories of abuse, with 84% of participants completing at least one full day of adherent sampling. While the decentralised approach yielded usable cortisol data, women with histories of forced sex exposure showed lower protocol adherence scores.
