Here is your comprehensive Parkinson's Disease infographic! It covers all five requested areas drawn from authoritative medical textbooks (Textbook of Family Medicine, Goldman-Cecil Medicine, and Bradley & Daroff's Neurology):
-
Introduction - Epidemiology, pathophysiology (dopaminergic neuron loss in substantia nigra, Lewy bodies), and the 4 cardinal features (tremor, rigidity, bradykinesia, postural instability)
-
Drug Classification - 6 color-coded classes: Levodopa/Carbidopa, Dopamine Agonists, MAO-B Inhibitors, COMT Inhibitors, Anticholinergics, and NMDA Antagonists
-
Mechanism of Action - Each drug class with its specific mechanism (BBB crossing, receptor binding, enzyme inhibition, etc.)
-
Uses - Specific indications per drug class, including when to prefer one over another (e.g., dopamine agonists in patients under 65, levodopa for rapid control)
-
Adverse Effects - Key side effects per class, including the serious ones (levodopa dyskinesias, dopamine agonist impulse control disorders, tolcapone hepatotoxicity)
The surgical option (Deep Brain Stimulation) is noted at the bottom as a fallback when medications fail.
