1. What Is Lambert-Eaton Myasthenic Syndrome-LEMS?
Lambert-Eaton Myasthenic Syndrome-LEMS is a rare autoimmune disorder where the immune system mistakenly attacks voltage-gated calcium channels (VGCC) at neuromuscular junctions. These channels are critical for transmitting nerve signals to muscles. When disrupted, it leads to muscle weakness, fatigue, and autonomic dysfunction.
Key Pathophysiology:
- VGCC Antibodies: Block calcium entry into nerve terminals, reducing acetylcholine release.
- Cancer Link: 50–60% of cases are paraneoplastic, often linked to small cell lung cancer (SCLC).
- Autoimmune Mechanism: T-cells target presynaptic nerve terminals, worsening neuromuscular communication.
Early diagnosis by a neuro doctor in Cuttack like Dr. Rohit Chhirolya—renowned as the best neurology specialist in Cuttack—is vital to prevent irreversible muscle damage. At Nilakantha Brain Clinic, we combine advanced diagnostics, immunotherapy, and cancer screening for holistic LEMS management.
2. Symptoms & Causes of Lambert-Eaton Myasthenic Syndrome-LEMS
Symptoms
- Proximal Muscle Weakness: Difficulty standing from a chair or climbing stairs.
- Autonomic Dysfunction: Dry mouth, constipation, orthostatic hypotension, or blurred vision.
- Reduced Reflexes: Absent knee-jerk or ankle-jerk reflexes.
- Transient Improvement: Brief strength increase after repetitive muscle use.
Causes & Risk Factors
- Autoantibodies: Anti-VGCC antibodies (P/Q-type) in 85–90% of cases.
- Genetic Susceptibility: HLA-DQ5 and HLA-B8 gene variants increase risk.
- Environmental Triggers: Smoking (due to SCLC link) or viral infections.

3. How Lambert-Eaton Myasthenic Syndrome-LEMS Differs from Myasthenia Gravis-MG
Feature | LEMS | Myasthenia Gravis (MG) |
---|---|---|
Muscle Weakness Pattern | Improves with activity | Worsens with activity |
Reflexes | Reduced/absent | Normal |
Autoantibodies | VGCC antibodies (85%) | AChR/MuSK antibodies (80–90%) |
Cancer Association | 50–60% linked to SCLC | Rare (<10%) |
4. Diagnosis & Advanced Testing
- Electromyography (EMG):
- Repetitive Nerve Stimulation (RNS): Shows incremental response (>100% increase post-exercise).
- Single-Fiber EMG: Detects abnormal neuromuscular transmission.
- Blood Tests:
- VGCC Antibody Test: 85% sensitivity for LEMS.
- Cancer Markers: NSE, ProGRP for SCLC screening.
- Imaging:
- CT Scan/PET-CT: Identifies lung tumors or metastases.
At Nilakantha Brain Clinic, Dr. Chhirolya uses 3T MRI and advanced antibody panels for precise differentiation from MG or ALS.
