While caregivers often struggle with stress and inefficacy in providing consistent support, dementia sufferers have great difficulties with memory loss, daily task management, recognizing loved ones, and safety concerns including wandering. Designed to solve these problems holistically, NeuroNest is an artificial intelligence app. With adaptive alerts that change frequency and method (text, voice, vibration) depending on patient responses, it provides emotion-based reminders using familiar voices—family or AI-generated—for tasks including taking medication, drinking water, or attending appointments. Task confirmations given to caregivers upon completion guarantee responsibility. Along with a memory recall function showing past images or plays recorded memories, the app also includes face and object recognition to enable patients identify family members and significant objects (e.g., medicine, keys) using the phone camera. NeuroNest offers location-based reminders (e.g., buy medicine near a pharmacy), geo-fencing to notify caregivers if the patient leaves a safe area, and an SOS button for emergency location alerts. An AI chatbot companion for conversation and reminders, cognitive games like memory recall and puzzles, and a mood tracker that recommends relaxing activities (music, meditation) are further ways it promotes emotional well-being and cognitive stimulation. NeuroNest eases patients' lives, lessens caregiver stress, and keeps families involved and connected by lowering confusion, increasing independence, and improving safety.
