Mindful Awareness and Blood Markers in Mild Cognitive Impairment: ELISA for an IMU-Led Pilot Study

Researchers led by IMU University tested whether 21 days of guided mindful awareness practice changes blood markers in older adults with mild cognitive impairment. The study's ELISA tests were performed at the Prima Nexus laboratory.

The challenge

Mild cognitive impairment is the stage between normal ageing and dementia. The kynurenine pathway breaks down the amino acid tryptophan, and the enzymes that drive it become more active with stress and inflammation. Very few studies have looked at this pathway in people with mild cognitive impairment, so the research team asked whether a short daily practice of mindful awareness could change these blood markers.

What Prima Nexus did

Blood samples were taken at the start (day 0) and after the practice (day 21). The stress hormone cortisol and the inflammation signal interferon-gamma (IFN-γ) were measured by ELISA, and the paper states that the ELISA was performed at the Prima Nexus laboratory. The kynurenine pathway markers were measured at a laboratory at Macquarie University in Australia.

What the study found

Forty adults joined and 36 completed the study: 17 practised 30 minutes of guided breathing and body scans each day, and 19 kept to their usual routine. In the practice group, tryptophan and kynurenine fell and IFN-γ rose. In the usual-routine group, cortisol and IFN-γ rose and tryptophan fell.

Most differences between the two groups were not significant, and mood scores did not change significantly. The authors note that thinking tests were not repeated after the practice, and call for longer studies with more participants.

Why it matters

Small pilot trials need reliable measurements so that the next, larger study can be planned with confidence. Prima Nexus runs ELISA testing for clinical and human studies in Malaysia.
