Sensing Mood to Counteract Dementia

Among the risk reducers for dementia in general and AD in particular are intellectual stimulation, regular physical exercise, and regular social interaction (see e.g. Ball et al., 2002; Kramer, et al., 1999; Seeman, 1996). Recent research has demonstrated the strong relationships between levels of sensory and physical stimulation and of social communication to both cognitive performance and psychological wellbeing (Fratiglioni et al., 2000; Park & Minear, 2005). But in many modern societies elderly people are increasingly isolated and physically, mentally and socially under-stimulated, as confirmed by recent surveys (see Rabbitt, 2005). The results are accelerated cognitive decline and the suffering associated with loneliness and increasing confusion and often anxiety. To motivate patients to be active, both physically and mentally, is therefore very important to maintain or improve the patient’s quality of life and to support ongoing therapies.
