Alzheimer's disease (AD) is the most common form of dementia diagnosed in people over 65 years of age. There is no cure for the disease, which worsens as it progresses, and eventually leads to death. As the disease advances, symptoms can include confusion, irritability and aggression, mood swings, trouble with language, and long-term memory loss. As the sufferer declines they often withdraw from family and society. Gradually, body functions are lost, ultimately leading to death. Current treatments only help with the symptoms of the disease. Following the vision of WHO and AD International for innovative approaches to AD, the system proposed here, namely Symbiosis, aims at creating a novel human-computer interaction (HCI) environment to facilitate, understand and incorporate the needs of the whole AD community (patients, caregivers and doctors).
