“…Epidemiological studies have shown that 30%-60% of all older persons have one or more sleep complaints, including difficulty falling asleep, problems staying asleep at night or falling back asleep after awakening, early morning awakenings, excessive daytime sleepiness, and daytime fatigue (Ancoli-Israel & Roth, 1999;Dodge, Cline, & Quan, 1995;Foley et al, 1995;Maggi et al, 1998). Sleep disturbances in this population are often secondary to medical and psychiatric comorbidities (Foley, Ancoli-Israel, Britz, & Walsh, 2004;Newman et al, 1997;Ohayon, Carskadon, Guilleminault, & Vitiello, 2004;Quan et al, 2005;Vitiello, Moe, & Prinz, 2002) and are associated with an increased risk for the onset of depression and anxiety, substance abuse, falls, cognitive decline, and suicide (Brassington, Kings, & Bliwise, 2000;Byles, Mishra, Harris, & Nair, 2003;Jelicic et al, 2002;Newman et al, 2000;Taylor, Lichstein, & Durrence, 2003).…”
