Alzheimer disease is mostly a condition of old age.Since life expectancy is getting longer around the world,the number of people affected by the brain diseaseis expected to triple in some countriesby the middle of the century.People with Alzheimer's often have other medical needsthat require the services of numerous health care professionals.Caregivers often have a hard timekeeping up with all the medical information.More and more family members are being called onto help care for loved ones with Alzheimer's.It is a responsibility for which most people are unprepared.This is why the Hebrew Home,a private health care group in Riverdale, New York,developed an iPhone and iPad application called Balance.The app offers caregivers adviceon recognizing symptoms and on feeding, bathingand providing a healthy environment for the patient.It can be bought on the Internet for four dollars.David Pomeranz is Hebrew Home's program development directorand he created Balance."It is not easy andwe hope this will make it a little easier for people."The Hebrew Home is a not-for-profit organization that provides careto 75,000 patients throughout New York City."We are dealing with their family membersbecause as a philosophy,we feel that we need to care for the caregiver equallyin our care needs the clients themselves,since if the caregiver does not have the proper supports,they simply cannot be a caregiver."Mister Pomeranz says the Balance software is designedto let users organize medical and other informationso they can easily keep track of the person's health.It helps caregivers manage doctor's appointmentsand share information with doctors about the patient's daily emotional changes.Interest in the app is not limited to the United States."It has been interesting to see thatwe have had apps purchased from Egyptto the Netherlands to Greece.It is like the United Nations every day,to see where people are buying this."David Pomeranz says software developersare working on a version of Balancefor mobile devices using the Android operating system.In a separate but unrelated story,scientists at Washington University School of Medicine in St. Louis, Missourihave identified genes linked to Alzheimer's disease.They say the discovery could help researchersdevelop new drugs against the brain disease.Go to 51voa.com to hear more about this story.And that's the Technology Report.Transcripts, MP3s and podcasts of our reportsare at 51voa.com.We are also on Facebook,Twitter and YouTube at VOA learning English.
