Movement problems and Lewy body dementia!: Biden??

Movement problems may include:
Muscle rigidity or stiffness
Shuffling walk, slow movement, or frozen stance
Tremor or shaking, most commonly at rest
Balance problems and repeated falls
Stooped posture
Loss of coordination
Smaller handwriting than was usual for the person
Reduced facial expression
