My mother has vascular dementia .She now spends all her time curled in the fetal position, doesn't open her eyes and whinnies like a horse. She is not in pain but this is her only way of communicating. She eats and drinks little ..has anyone else experienced this crying out. Is the end near? She doesn't look at me or communicate in any way she seems locked inside her head she just makes this noise and calls for one of her dead brothers.
