High cognitive reserve in bipolar disorders as a moderator of neurocognitive impairment
BackgroundCognitive reserve (CR) reflects the capacity of the brain to endure neuropathology, minimize clinical manifestations and successfully complete cognitive tasks. The present study aims to determine whether high CR may constitute a moderator of cognitive functioning in bipolar disorder (BD).MethodsOne hundred and two patients with BD and 32 healthy controls were enrolled. All patients met DSM-IV criteria for I or II BD and were euthymic (YMRS ≤ 6 and HDRS ≤ 8) during a 6-month period. All participants were tested with a comprehensive neuropsychological battery, and a Cerebral Reserve Score (CRS) was estimated. Subjects with a CRS below the group median were classified as having low C…
Driving impairment and crash risk in Parkinson disease: A systematic review and meta-analysis
ObjectivesTo provide the best possible evidence base for guiding driving decisions in Parkinson disease (PD), we performed a meta-analysis comparing patients with PD to healthy controls (HCs) on naturalistic, on-the-road, and simulator driving outcomes.MethodsSeven major databases were systematically searched (to January 2018) for studies comparing patients with PD to HCs on overall driving performance, with data analyzed using random-effects meta-analysis.ResultsFifty studies comprising 5,410 participants (PD = 1,955, HC = 3,455) met eligibility criteria. Analysis found the odds of on-the-road test failure were 6.16 (95% confidence interval [CI] 3.79–10.03) times higher and the odds of sim…
Chronic physical conditions, multimorbidity, and mild cognitive impairment in low- and middle-Income countries
BACKGROUND/OBJECTIVES: Chronic physical conditions and multimorbidity may be modifiable risk factors for dementia. However, data from low- and middle-income countries (LMICs) are lacking. This study thus assessed the association of chronic physical conditions and multimorbidity with mild cognitive impairment (MCI) in LMICs. DESIGN: Nationally representative, cross-sectional, community-based. SETTING: Six countries which participated in the World Health Organization’s Study on Global Ageing and Adult Health. PARTICIPANTS: 32,715 adults aged ≥50 years [mean (SD) age 62.1 (15.6) years; 51.7% females]. MEASUREMENTS: The definition of MCI was based on the recommendations of the National Institut…
