“…Alterations, most frequently increases, in beta oscillations have been observed during wake and sleep states in patients or animal models of PD [60][61][62][63][64][65][66][67][68] , HD 69,70,[79][80][81][82][83][84][71][72][73][74][75][76][77][78] , dementia with Lewy bodies 85,86 , insomnia 60,87 , and RBD 63,[88][89][90] . In PD, beta oscillations in the basal ganglia are usually pathological 60,62,64,67,68,91 and appear to be linked to basal ganglia dysfunction or compensation. Thus, the triad of RBD, beta oscillations, and basal ganglia appears to be a unifying feature of these diseases, including SCA3.…”
