OBJECTIVE This study examined the influence of illness phase on executive functioning performance using factor-derived cognitive scores in a cross-sectional design. METHODS Healthy control (HC) subjects (n = 57), and euthymic (E-BD) (n = 117), depressed (D-BD) (n = 73), and hypomanic/mixed (HM/M-BD) (n = 26) patients with bipolar disorder (BD) were(More)
Functional recovery, including return to work, in Bipolar Disorder (BD) lags behind clinical recovery and may be incomplete when acute mood symptoms have subsided. We examined impact of cognition on work status and underemployment in a sample of 156 Euthymic-BD and 143 controls (HC) who were divided into working/not working groups. Clinical, health, social(More)
Little is known about the service needs for persons caring for individuals with mild cognitive impairment (MCI). In this study, the level of support service need for caregivers of individuals diagnosed with Alzheimer disease (AD; N=55) and MCI (N=25) was compared with normal controls (N=44). Study partners (ie, caregivers) completed questionnaires about(More)
