Stage 4 is described as: Stage 4 is the point where memories clash and create pure terror. Very Few moments are audible where the patient will recognize at least one person around themselves. Side G is a transition to confusions, and delirium. Sides H and J are points where the patient can barely recognize anything around them. at this point, they have forgotten that they have Dementia. Side I is a short state of bliss, where happy memories that are shattered replaced the doom and gloom of pure terror. oh and btw this stage is over 40 minutes, and probably over an hour.
