“…Previous studies have suggested that rTMS (Ahmed et al, 2012; Cotelli et al, 2006, 2008, 2011; Eliasova et al, 2014; Kim et al, 2012; Rabey et al, 2013; Sole-Padulles et al, 2006) or tDCS (Berryhill and Jones, 2012; Boggio et al, 2009, 2012; Cotelli et al, 2014; Ferrucci et al, 2008; Fertonani et al, 2014; Floel et al, 2012; Harty et al, 2014; Holland et al, 2011; Khedr et al, 2014; Manenti et al, 2013; Meinzer et al, 2013, 2014; Park et al, 2014; Ross et al, 2011; Sandrini et al, 2014) may have beneficial effects on various cognitive functions in healthy older adults and patients with AD. By applying a single session of rTMS or tDCS, studies have demonstrated that both of these techniques are capable of positively influencing cognitive functions among older participants (Berryhill and Jones, 2012; Fertonani et al, 2014; Floel et al, 2012; Harty et al, 2014; Kim et al, 2012; Manenti et al, 2013; Meinzer et al, 2013, 2014; Park et al, 2014; Ross et al, 2011; Sandrini et al, 2014; Sole-Padulles et al, 2006) and patients with AD (Ahmed et al, 2012; Boggio et al, 2009, 2012; Cotelli et al, 2006, 2008, 2011; Eliasova et al, 2014; Ferrucci et al, 2008; Khedr et al, 2014).…”
