Welcome to Ali 🧠💬

Your AI Companion for Early Alzheimer’s Detection and Elderly Care

The Problem 🌍

• 🧩 Misdiagnosis is a major contributor to medical errors, especially with complex diseases like Alzheimer’s, where symptoms are often subtle and develop over time.
• 🧠 Alzheimer’s dementia (AD) is particularly difficult to diagnose early, often leading to delayed treatment. By the time recognizable symptoms appear, the disease has already advanced, making intervention less effective.
• 💰 Current diagnostic methods, like MRI scans, are costly, resource-intensive, and not always accurate, leading to medical errors and misdiagnosis.

Our Solution 🌟

Ali is an AI-powered mobile app that not only helps detect early signs of Alzheimer's through natural speech analysis but also provides elderly companionship, reducing the emotional and cognitive isolation that many experience. Our solution minimizes medical errors by providing continuous, real-time data on cognitive health, empowering doctors with the insights they need for more accurate diagnoses.

• 🧠 Minimizing Medical Errors: By passively collecting speech data and monitoring cognitive patterns over time, Ali helps reduce the risk of misdiagnosis. This continuous, non-invasive approach gives doctors critical insights that are often missed in sporadic tests, ensuring early detection and reducing the chances of late-stage diagnosis.
• 🗣️ Companionship for the Elderly: Ali isn’t just a diagnostic tool—it’s a conversation partner. Through natural, engaging conversations, Ali provides emotional support and cognitive engagement, helping to combat the loneliness many elderly individuals face.
