Avoid Diagnostic Pitfalls For Parkinson's Disease

▸ Unilateral lower extremity presentation. “When a patient presents with one lower-extremity symptom, even if he or she complains of pain or weakness, don't discount PD,” Dr. Reich said.

▸ Atremulous PD. Patients with atremulous PD are most often misdiagnosed with stroke, but the fact that only half the body is affected by stiffness or balance problems is a tip-off that the problem might be PD instead, Dr. Reich said.
