This pattern is typical of DLB at early stage. After six months, she reported attention deficits in association with cognitive fluctuation and REM sleep behavior disorder. The neurological examination revealed signs of parkinsonism. Cognitive status resulted to be impaired (MoCA\u200a=\u200a15\/30). QEEG recording confirmed the presence of a DLB-typical pattern (DF\u200a=\u200a7.5\u200aHz, DFV\u200a=\u200a2.5\u200aHz).
