Hi, my dad is 61 years old and has both legs amputated, diabetes and his behavior has been weird for about ten years. To my concern: My dad has not been getting any sleep whatsoever so he sits with his ipad in bed, and he watches shows and weddings from our homecountry in Africa. Anyway, when they talk in the videos he responds to them and has a dialoge with them, we have explained that its a video but he doesnt realize that, this is something that has been going on for three days now.
