A large-scale observational study has suggested that smartphones and watches may be able to spot mild cognitive impairment (MCI) during daily usage.
The study enrolled more than 23,000 adults aged 21 to 86 across the US who used an iPhone, with the cohort ranging from people who were cognitively healthy to those diagnosed with MCI.
They were asked to use their phone and wear an Apple Watch daily and take cognitive assessments on their own whilst also completing questionnaires on a monthly and quarterly basis.
The results of the Intuition Brain Health study – sponsored by Biogen and supported by Apple – show the feasibility of using passive sensors on devices such as the iPhone and Apple Watch, alongside other metrics, to chart changes in thinking and memory over time that could point to MCI.
