G20-G26: Extrapyramidal and movement disorders
G21: Secondary parkinsonism
Secondary parkinsonism is a group of conditions that cause symptoms similar to those of Parkinson's disease including tremors, stiffness, and balance problems. Unlike the more commonly known Parkinson's disease which is primarily caused by unknown factors, secondary parkinsonism diseases are caused by certain medications, strokes, brain tumors, or as a result of damage to the brain due to other health disorders. Symptoms occur as the conditions affect the nerve cells in the brain that control movement, resulting in difficulties with movement and coordination. These conditions typically progress over time and the severity varies based on the underlying cause. It's important to note that secondary parkinsonism disorders are distinctly different from Parkinson's disease, though they do present similar symptoms.
