Diagnosis typically involves a combination of: - Clinical evaluation: Detailed patient history and physical examination. - Electromyography (EMG): Measures electrical activity in muscles. - Nerve conduction studies: Assess the speed and strength of signals traveling through nerves. - Imaging studies: MRI or CT scans to detect tumors pressing on nerves or muscles. - Blood tests: To identify paraneoplastic antibodies or metabolic imbalances.
