Hi I have just registered to this site although I have been reading a lot of its content for the last few months and have found a lot of information for which I am grateful. My mother has been diagnosed with Alzheimers and has had two MMSE tests in the last eight months both of which were below 10. However, and I realise that I am in a very lucky position in that my mother only lives across the road from myself and my family all help look after her. She has been on Aricept for the last six months but my mother now has no sense of time or day and basically works to the light of the day or the dark of the night. Sometimes my mum has walked across the road to our house after I have put her to bed on at least three occasions. Luckily I have still been awake. Does anybody know whether it is possible to purchase or have any information about an alarm system that if my mothers front door opens especially at night that a buzzer or bell would ring in our house ( approx 30yards away). Any advice would be appreciated. Thank you.
