“…Consequently, individuals with IDD receive more prescriptions per year and are at greater risk for polypharmacy than the general population (Straetmans, van Schrojenstein Lantman-de Valk, Schellevis, & Dinant, 2007). In particular, the prescribing of psychotropic medication is common among individuals with IDD with rates of psychotropic medication usage estimated between 28% and 89% (Bisconer, Sine, & Zhang, 1996;Burd et al, 1997;Lott et al, 2004;Molyneux, Emerson, & Caine, 1999;National Core Indicators, 2012;Spreat, Conroy, & Fullerton, 2004). Antipsychotic drugs are the most commonly prescribed psychotropic medications among individuals with IDD (Aman, Lam, & Collier-Crespin, 2003;Aman, Lam, & Van Bourgondien, 2005;Esbensen, Greenberg, Seltzer, & Aman, 2009;Hurley, Folstein, & Lam, 2003;Marshall, 2004;Molyneux et al, 1999;National Core Indicators, 2012;Robertson et al, 2000;Spreat et al, 2004).…”
