Enhanced CBTi for Older Adult Sleep and Cognition

Telehealth-delivered enhanced CBTi (integrated with a sleep diary app, a therapist dashboard, and data from IoT devices) will be compared to standard telehealth CBTi and to usual treatment with sleep hygiene education. The investigators will determine effects on insomnia (primary outcome) and on clinical sleep metrics (secondary outcome), among other outcomes including cognitive performance, blood biomarkers of ADRD, and therapeutic adherence. After screening consent and qualification, informed consent, and adherence evaluation with ambulatory devices (1wk), study participants are pseudo-randomized into one of 3 study arms (2:2:1, Enhanced CBTi : Standard CBTi : Sleep Hygiene). The living space of participants is equipped with IoT data collection devices. Participants take surveys related to sleep, have blood drawn, wear ambulatory devices, complete cognitive evaluations, and interact with nearable living space devices and an iPhone interface during a preparation week leading up to an intake telehealth appointment. Baseline data collection (1wk) occurs. Participants then adhere to behavioral therapy directives prescribed at weekly telehealth sessions with a clinically qualified therapist, take surveys related to sleep, complete cognitive evaluations, wear ambulatory devices, and interact with nearable living space devices and an iPhone interface throughout the study intervention period of 6 weeks. During the final week (coinciding with the 6th intervention week), participants have a second blood draw and return all study equipment/devices at the conclusion of participation.
