The most prevalent neurological disease is Alzheimer's. In recent years, older people's use of smart devices has exploded. Motion sensors can be used to maintain tabs on patients' daily activities and monitor them. The same is true for pressure
sensors and fitness trackers. JSP Servlets are frequently used to develop
datasets created on servers or in the cloud.

According to “alz”, there are more than 4 million dementia sufferers in India. Since dementia affects at least 44 million individuals worldwide, the condition has become a global health emergency. One in ten Americans over 65 today have Alzheimer's
disease. By 2050, that figure is anticipated to reach 16 million. As a result,
there is a huge demand for Dementia and alzheimer care at home.

The signs of this illness are:

● Difficulty accomplishing previously simple tasks.

● Problem-solving challenges.

● Mood or behavior changes; estrangement from friends and family.

● Issues in verbal or written communication.

● Uncertainty regarding individuals, locations, and events.

● Modifications to vision, such as difficulty comprehending images.

The IoT devices for Dementia and Alzheimer care make it simple to monitor this condition based on the symptoms.

a. Motion sensors, first A device known as MESH 100 MD exists. It produces Motion Tag, an input device that tracks the movement of both people and animals. One might use this tag to find out how frequently a particular space, such as the restroom,
is used by one's family or relatives. Daily movement data is kept in a database
that machine learning algorithms can use to process. The monitoring software
gradually learns the patient's routine. The computer notifies the monitoring
firm when there is a variation from the routine so that they can check to see
if there is an issue before getting in touch with the family.

b. Switches for pressure - The bottom of the patients' socks can covertly accommodate this sensor. The family member's smartphone receives a notification when they move, and the wandering is also logged for further analysis. This is often used when
patients don't maintain a regular sleep schedule because poor sleep is the
leading cause of their memory loss. In that case, doctors can prescribe
medications. Sensors might be set in the kitchen cabinets or refrigerator to
track when the patient has eaten or taken anything to eat.

c. The patient's sleep cycle can be recorded using fitness monitors like Fitbit. Understanding the patterns of light and deep sleep can assist clinicians in better comprehending what their patients are doing at night. Instead of using pressure
sensors to track the patient's movement at night, this is the more
straightforward method.

Conclusion

In old age, the emergence of numerous diseases, including Alzheimer's, is one of humanity's most significant issues today. The prevalence of this condition has increased globally over the past ten years for unclear causes. Despite extensive
investigation from researchers throughout the globe, it is still unknown what
the disease's underlying causes are. Doctors can provide good Alzheimer's
and dementia care using IoT devices.

Doctors can track the data of the patients through IoT devices. For instance, if sensors notice a patient using the restroom frequently, it may indicate a prostate issue or urinary tract infection. A doctor can examine a patient's eating habits to provide
nutritional supplements and meal plans for continuing health.
