It is a chronic neurodegenerative disease that usually starts slowly and gets worse over time. In Alzheimer disease death of the brain cells causes memory loss and cognitive decline. The early diagnosis of the disease is essential as it helps the patients also his family to take preventive measures. EEG can be used for diagnosis of Alzheimer Disease. In the EEG signals of the patients suffering from Alzheimer disease various abnormalities are found . Hence, the need is to develop the detection of the disease in early stage called as Dementia. Developing tracking and reminder system for Alzheimer patients who suffer from many difficulties such as Memory loss that disrupts daily life, challenges in planning or solving problems, Difficulty completing familiar tasks, Confusion with time and place, problem with words in speaking or writing. Key Words: mild cognitive impairment(MCI), electroencephalogram(EEG), Global System for Module(GSM), Global Positioning SystemȋGPSȌ, Alzheimer’s diseaseȋADȌ, family caregivers(FC), Electronics Geo-Tracking(EGT) 1.INTRODUCTION AD is the most common cause of dementia, and involves a progressive degeneration of the cerebral cortex. There is widespread cortical atrophy. Neurons affected develop surrounding amyloid plaques, neurofibrillary tangles, and produce less acetylcholine. Alzheimer’s disease ȋADȌ, also known as Alzheimer disease, or just Alzheimer’s, accounts for 60% to 70% of cases of dementia[10].People aged 65 and older constitute the fastest growing population segment in North America, Europe, and Asia. According to the US Census Bureau, the global number of adults over the age of 60 is expected to reach 1.2 billion by the year 2025.In Canada , 50% people is affected due to Alzheimer disease. Early detection of dementia is of great significance because it increases the chances of successfully reversing the cause of dementia. Although no treatment exists , early detection of dementia still provides them and their families with an opportunity to proactively plan for their future. [5].It is a chronic neurodegenerative disease that usually starts slowly and gets worse over time. The cause of Alzheimer’s disease is poorly understood. About 70% of the risk is believed to be genetic with many genes usually involved. Other risk factors include a history of head injuries, depression, or hypertension. AD is classified into three stages on the basis of symptoms. Firstly, MCI: symptoms of MCI is short-term memory loss, poor in calculation, frequently forgetting people name, appointments, recent events. Secondly, Moderate: symptoms of moderate is severe memory loss, unable to handle simple tasks, start to depend on others on handling living activities, language problems and cannot communicate clearly with other people, wander around on streets, confused about day and night. Symptoms of last stage is unable to understand or use speech to express simple things, unable to recognize people including his close family members, Difficulties in swallowing and walking, Totally dependent and bedridden. Numerous clinical methods are extensively used for the diagnosis of Alzheimer disease such as neuroimaging techniques[19], physiological markers, and genetic analyses. Neuroimaging is one of the well-accepted methods for definitive diagnosis of dementia. Various Neuro-imaging methods are used for the diagnosis of the Alzheimer disease. Several methods such as single- photon emission computerized tomography (SPECT), positron emission tomography (PET), and magnetic resonance imaging (MRI) have been successful for recognizing AD at an early stage. But the main problem of PET & SPECT is they impose the radiation risks[9]. Other disadvantages are their costs which are much expensive, time consuming inconvenient. So, apart from all these Neuro-imaging methods; EEG is one of the standard methods used for the diagnosis of the Alzheimer disease. 2. RELATED WORK Current detection process starts by general practice physicians referring patients to memory clinics for cognitive assessment after repeated reports of memory problems by the patients themselves, family members, or caregivers[5].In memory clinics, cognition of patients is assessed using
