Abstract: Dementia is not a single disease; it’s an overall term like heart disease that covers a wide range of specific medical conditions, including Alzheimer’s disease. Disorders grouped under the general term “dementia” are caused by abnormal brain changes. These changes trigger a decline in thinking skills, also known as cognitive abilities, severe enough to impair daily life and independent function. They also affect behaviour, feelings and relationships. Alzheimer's disease accounts for 60 to 80 percent of cases. Vascular dementia, which occurs because of microscopic bleeding and blood vessel blockage in the brain, is the second most common cause of dementia. In order to overcome this problems and provide proper treatment to theelder people our project aims at developing an application for elderly age people dementia prediction where I can lively monitor the blood glucose, blood pressure, blood oxidation level which is measured using the sensors and if the condition is abnormal the SMS API will send a message to a mobile phone of the care taker or the old age home in-charge. The web application developed in this project displays the three parameters to the user on a computer that can be lively monitored using IoT. An efficient real time microcontroller is used to process the information and a Wi-Fi gateway is used to transmit the data wirelessly. Thus this project helps in taking care of the elder people at the right time and avoid difficulties. Keywords: MQTT protocol, Publishing, Subscribing, Web application module.
