Parkinson's Disease: What a Neurologist Wants You to Know Before Symptoms Start

Dr. Maheep Virdi is a board-certified neurologist who joins Dr. Rasham Sandhu to walk through Parkinson's disease in depth, from the earliest, easy-to-miss symptoms through the latest treatment technology.In this conversation, they cover:The soft early symptoms that can precede a Parkinson's diagnosis by roughly six years, including new-onset constipation, shoulder pain unrelated to movement, difficulty turning over in bed, and REM behavior disorder (physically acting out dreams)The gut-brain connection in Parkinson's, including how the vagus nerve links the gut to the brain and how a protein called alpha-synuclein, produced by certain gut bacteria, may travel to the brain and contribute to the diseaseEnvironmental risk factors including paraquat and other pesticides, manganese exposure from welding, the industrial solvent TCE, carbon monoxide exposure, air pollution, and contaminated well waterWhy coordination-focused exercise, such as small hand-muscle work, balance training, dancing, Tai Chi, and boxing, has shown more benefit for Parkinson's patients than strength training or high-intensity cardioDietary guidance including the Mediterranean diet, avoiding processed foods, and why patients need to separate protein intake from their carbidopa/levodopa medication by at least an hour, since dietary protein competes with the medication for transport across the blood-brain barrierThe DaTscan, a diagnostic imaging test used alongside clinical evaluation rather than as a standalone diagnosisGenetic factors, including the LRRK2 and parkin genes, and why genetic testing alone hasn't proven to be a reliable predictorDeep brain stimulation (DBS): how it works, its dramatic effect on tremor, and the extensive psychological screening required beforehand due to a risk of suicidal ideationNewer treatment technology, including subcutaneous infusion devices for carbidopa/levodopa and a newer drug pathway (A2A receptor antagonist) that works outside the traditional dopaminergic systemA rapid-fire round on coffee, alcohol, sauna, cold plunge, artificial sweeteners, and other everyday lifestyle factors and their effect on Parkinson's risk
