Late‐onset panic disorder as the initial presentation in autopsy‐confirmed dementia with Lewy bodies

editor,Lewybody disease (LBD) encompasses two clinicopathological syn-dromes associated with Lewy bodies (LB): Parkinson ’ s disease and dementia with Lewy bodies (DLB). 1 Both disorders share prodromal symptoms such as anxiety and rapid eye movement (REM) sleep behavior disorder (RBD), which precede the disorders by years or decades before the clinical criteria are ful fi lled.
