Great article about some interesting technology on trial in the US - where a belt connected wirelessly measures breathing while sleeping. Is able to identify patterns in breathing consistent with dementia and Parkinsons (math included suggests AUROC of 0.9 in test sets and 0.85 in the wild). Most interesting bit is how they built the model (combined with EEG data) to identify the breathing pattern - looks like it also has very prognostic power with 12 being identified as Parkinsonian who were in the diagnosed group.
