Assessing Cognitive Decline at Home

What the investigators would need from participants: * Collect the participants' own data of daily activities from a room in participants home such as the participant's living room via a small camera the investigators provide for no less than 7 days and up to 30 days. The participant will have full control over the camera to turn on and off. * The participant and a loved one will regularly answer short surveys asking about the participant's mood and daily functioning. * At the end of agreed observation period, return the memory card of the participant's collected data from the camera in person or pre-paid FedEx envelope.
