The incredible story of the woman who can smell Parkinson's. Seventy-two-year-old Joy first recognised her superpower when she realised she could smell the disease in her own husband. She is now working with a team of medical scientists to help develop earlier detection of the illness.Also, the terrible tale involving thousands of patients who were recalled and re-evaluated after a neurologist was found to be misdiagnosing patients. Janelle started seeing Dr Michael Watt with headaches, but after six months of treatment and several invasive and unnecessary procedures, she escaped his care. Many other patients were not as lucky.Plus, the people defrauding the NHS by selling on prescriptions they no longer need. It's a lucrative business and also illegal.And we're discussing the hype around hydration. Do we really need eight glasses of water a day? Do tea and coffee dehydrate you, and why does alcohol make you feel so dried out? Dr Xand has the answers.
