Hello everyone - I am very glad to have found you all! My 86 year old father has Alzheimers he lives alone generally just about managing with frequent visits from the family - he refuses to consider living with my husband and me. He walks for miles every day and is physically very fit. Recently he has started coming to my house at all hours of the day and , more worrying, the night - he has no idea of what day it is or what time. I am really worried about him - mainly about him walking the streets at night. Any suggestions as to how I can help him ?
