Parkinsonism in Lewy body dementia can include stiffness, difficulty rising, shuffling gait, and reduced arm swing, but typically lacks resting tremor.

“there is a parkinsonism component where they will often be stiff have trouble rising from a chair shuffle they may decrease arm swing when they walk so that they walk and you know normally when we walk our arms move but their arms don't move they may have more um less or i should say less expression on their face so that they don't necessarily have a tremor so true parkinson's disease proper often begins with a tremor a slow writhing kind of tremor at rest on one side and often we don't see that in lewy body disease”
