AI in Healthcare — Diagnosis & Drug Discovery
Disease diagnosis, AlphaFold, drug discovery, telemedicine, robotic surgery — complete notes for UPSC & PSC exams.
🏥 AI Applications in Healthcare
| Application | Details |
|---|---|
| Disease Diagnosis | AI reads X-rays, MRIs, CT scans; detects cancer, diabetic retinopathy, COVID-19; often more accurate than doctors |
| Drug Discovery | AI accelerates drug development; AlphaFold predicts protein structures; reduces time from 10+ years to months |
| Telemedicine | AI-powered chatbots for preliminary diagnosis; eSanjeevani uses AI; 300 million+ consultations |
| Robotic Surgery | Da Vinci surgical robot; AI-guided precision surgery; smaller incisions, faster recovery |
| Epidemic Prediction | AI models predict disease outbreaks; WHO uses AI for early warning |
| Personalised Medicine | AI analyses genomic data to recommend personalised treatments |
🏥 AlphaFold — Revolutionary AI
- Developed by DeepMind (Google subsidiary)
- Predicts the 3D structure of proteins from amino acid sequences
- Solved the “protein folding problem” — a 50-year-old challenge in biology
- Predicted structures for nearly all known proteins (~200 million)
- Developers won Nobel Prize in Chemistry 2024
- Revolutionises drug discovery — understanding protein structure is key to developing drugs
