My husband can be walking fairly well until he moves from a well lit area into darkness. At that point he freezes instantly and cannot move until there is light provided. I have to make sure in the evening that bedroom and bathrooms are well lighted ahead of the time of need. In spite of the bright night lights placed everywhere he might possibly need to go during the night, They do not help. He cannot move until a room light is turned on. He can no longer go outside to enjoy the garden on our pleasant summer evenings, even at dusk when others can see quite well. Martha Rohrer CG for Neal, 79/14 [log in to unmask]
