What are the core features of DLB in the McKeith criteria?

Core features are fluctuating cognition, recurrent visual hallucinations, REM sleep behavior disorder, and parkinsonism. Presence of two or more core features supports probable DLB.

Why is DLB probability important for prescribing decisions?

DLB patients have severe neuroleptic sensitivity — antipsychotics can cause irreversible parkinsonism or death. Identifying probable DLB is critical before prescribing any dopamine-blocking agent.
