Neuromuscular Disorders

Dr. Mahajan has advanced training and a deep interest in diagnosing and managing neuromuscular disorders — conditions that affect the muscles, peripheral nerves, or the junction between them.

Myopathies and Muscular Dystrophies

These are disorders where muscles become weak or damaged due to genetic or acquired factors. Dr. Mahajan evaluates and manages:

• Limb-girdle muscular dystrophy (LGMD): Progressive hip and shoulder weakness, often hereditary
• Duchenne/Becker muscular dystrophy: Seen in children/adolescents, X-linked, affects walking and heart muscles
• Facioscapulohumeral muscular dystrophy (FSHD): Involves facial, shoulder, and upper arm muscles
• Inflammatory myopathies: Polymyositis, dermatomyositis – autoimmune muscle inflammation
• Metabolic myopathies: Like Pompe disease, often detected by enzyme or genetic testing
• Full diagnostic workup including blood tests (CK levels), EMG, MRI, genetic panels, and muscle biopsy referrals
• Long-term rehabilitation, mobility aid planning, and cardiac/respiratory screening

Motor Neuron Diseases (including ALS)

Motor neuron diseases cause progressive weakness and disability:

• Amyotrophic lateral sclerosis (ALS): Involves both upper and lower motor neurons—leading to muscle wasting, spasticity, and respiratory failure
• Progressive muscular atrophy (PMA) or primary lateral sclerosis (PLS) variants
• Dr. Mahajan provides a multidisciplinary care model including respiratory monitoring (spirometry), speech and swallowing evaluations, and palliative care integration
• Focus on quality of life, caregiver support, and early planning for assistive technologies

Myasthenia Gravis and Neuromuscular Junction Disorders

These are autoimmune conditions affecting the communication between nerves and muscles:

• Myasthenia Gravis: Presents with drooping eyelids, double vision, swallowing difficulty, or limb weakness—typically worsens with activity
• Diagnosis via antibody testing (AChR, MuSK), repetitive nerve stimulation, and response to medications
• Treatment with acetylcholinesterase inhibitors (e.g., pyridostigmine), immunosuppressants, plasmapheresis/IVIG during crises, and thymectomy evaluation

Peripheral Neuropathies and Plexopathies

• Includes chronic inflammatory demyelinating polyneuropathy (CIDP), multifocal motor neuropathy, vasculitic neuropathies, and traumatic plexus injuries
• Diagnosis based on detailed history, clinical signs, EMG/NCS, imaging, and sometimes nerve biopsy
• Immune therapies, physiotherapy, and symptomatic management offered in a comprehensive care model
