dementia is characterized by progressive symptoms like as behavioral abnormalities and memory loss, which eventually affect the patient's day-to-day functioning and demand for long-term care. Nevertheless, during a yearlong quiet phase, early symptoms are associated with structural and molecular alterations in the brain that can be identified by changed AD biomarkers. The pathogenesis of Alzheimer's disease is still unknown despite a great deal of research. Notably, the main theories concerning this neurological condition suggest that aberrant changes in tau and amyloid beta (Aβ) proteins initiate the preclinical phase of AD, which results in the buildup of plaques and tangles in the entorhinal cortex and neocortex. These neurological advancements are comparable to the agingrelated alterations that occur naturally [1]. A neurological condition affecting the central nervous system, epilepsy is characterized by aberrant brain activity that can lead to convulsions or episodes of strange behavior, sensations, and occasionally unconsciousness. Epilepsy can affect everyone. Males and females of various racial and ethnic backgrounds and ages are affected by epilepsy. The symptoms of seizures might vary greatly. During a seizure, some epileptics merely stare blankly for a few seconds, while others move their limbs or legs continuously. You do not necessarily have epilepsy if you have only one seizure. In most cases, a diagnosis of epilepsy requires at least two unprovoked episodes. Most patients with epilepsy can control their seizures with medication or occasionally surgery. While some people's seizures eventually stop, others need lifetime treatment to manage them. As they get older, some kids with epilepsy may outgrow the disorder [2]. Alzheimer’s disease is a neurodegenerative disorder that primarily affects memory, thinking, and behavior. As the condition progresses, individuals struggle with routine activities such as remembering daily tasks, taking medications on time, or communicating their needs effectively. This leads to increased dependency on caregivers and poses significant health and safety risks for the patient In response to these challenges, this paper presents the design and implementation of a Smart Health
neurological condition that causes dementia. Alzheimer's patients have trouble remembering recent events, reasoning, and even recognizing faces. Mood swings, loss of desire, difficulty speaking, disorientation, including getting lost, and general behavioral problems are some of the symptoms that may appear as the illness worsens. Although some IT-based solutions are available to assist individuals with Alzheimer's, most of them provide highly specialized services for both patients and caregivers. The goal of this project is to provide an assistive technology that will support Alzheimer's patients and their caregivers with activities including location tracking, medication reminders, and health monitoring. The evaluation study indicated that the recommended approach was effective and practical for patients and their caregivers. A number of usability tests and feedback sessions with patients and caregivers were used to assess the system. According to the findings, the tool considerably raises the standard of care, increases the independence of people with Alzheimer's, and lessens the stress experienced by caregivers. The system was deemed user-friendly and efficient by the participants in meeting daily requirements.

1. INTRODUCTION Since it allows for prompt intervention and lessens the substantial societal and financial burden of chronic diseases, early diagnosis is an essential component of health promotion. Around the world, Alzheimer's disease (AD) is commonly acknowledged as a degenerative chronic illness that mainly affects those 65 and older. As the population ages, this irreversible neurological disease is expected to grow at a pace of 60% between 2020 and 2030 and 204% by 2050. There are currently four different stages in the AD continuum: preclinical, mild,
