Disability, caregiver burden, cognitive and nutritional status, body mass index, balance, behavioral and psychological symptoms of dementia, medication, hospitalization, institutionalization and death were reported every six months during the four years.
Some covariates considered in the present analyses were computed as time-dependent variables: disability, caregiver burden, cognitive and nutritional status, body mass index, balance, behavioral and psychiatric symptoms of dementia (BPSD), medication, hospitalization, and institutionalization were reported at the clinic visit every six months.

Overall, it is generally argued that testosterone levels are kept at an optimum that is well balanced with the various behavioral and physiological costs of maintaining them (Folstad and Karter 1992; Wingfield et al. 2001; Adkins-Regan 2005; Hau 2007).
