“…Cross-sectional research suggests several health-related lifestyle factors are linked to cognitive status, particularly nutrition (Corrêa-Leite, Nicolosi, Cristina, Hauser, & Nappi, 2001), cigarette smoking (Hill, Nilsson, Nyberg, & Bäckman, 2003;Kalmijn et al, 2002;Razani, Boone, Lesser, & Weiss, 2004;Richards, Jarvis, Thompson, & Wadsworth, 2003;Zhou et al, 2003), alcohol consumption (Britton, Singh-Manoux, & Marmot, 2004;Espeland et al, 2005;Harris, Albaugh, Goldman, & Enoch, 2003;Kalmijn, van Boxtel, & Verschuren, 2002;Leroi, Sheppard, & Lyketsos, 2002;Perreira & Sloan, 2002;Schinka, Belanger, Mortimer, & Borenstein-Graves, 2003;Zhang, Heeren, & Ellison, 2005;Zhou et al, 2003), and physical activity (Churchill et al, 2002;Dik, Deeg, Visser, & Jonker, 2003;Emery, Shermer, Hauchk, Hsiao, & MacIntyre, 2003;Heyn, Abreu, & Ottenbacher, 2004;Hillman, Belopolsky, Snook, Kramer, & McAuley, 2004;Schuit, Feskens, Launer, & Kromhout, 2001;Yaffe et al, 2003). Although the research is somewhat mixed, cigarette smoking is a risk factor for healthy cognitive functioning, the relationship of alcohol use seems to favor moderate drinkers, and there is little doubt that a physically active life is good for the brain.…”
