Muscle Weakness and Fatigue
Pediatric neuromuscular disorders affect the nerves that control the muscles for voluntary movements and the nerves that communicate with the brain. Healthy nerve cells, called neurons, transmit electrical signals that help control the body's ability to move. When those neurons don't work correctly, communication between the muscles and nervous system is reduced. When this happens, it causes muscle atrophy, where the muscles waste away and weaken.
Pediatric neuromuscular disorders include:
- Arthrogryposis: causes stiffness and reduced mobility in more than one joint
- Cerebral palsy: a group of disorders that affect the ability to maintain balance and movement
- Muscular dystrophy: an inherited, progressive condition that leads to muscle weakness and loss that often worsens over time
- Myelomeningocele: a type of spina bifida that prevents the spinal canal and backbone from closing before birth
- Rett syndrome: a rare, genetic disease that mostly affects girls and causes developmental and nervous system issues
- Spinal muscle atrophy: a genetic disease that attacks neurons in the spinal cord and weakens the muscles that control crawling, breathing and walking
- Charcot-Marie Tooth Disease (CMT), Chronic Inflammatory Demyelinating Polyneuropathy (CIDP), Congenital Myopathy, Guillain-Barre Syndrome (GBS), Myasthenia Gravis, Myotonic Dystrophy, Congenital Myasthenic Syndrome, Congenital muscular dystrophy, Friedreich’s ataxia, mitochondrial myopathies, metabolic myopathies.
Pediatric neuromuscular conditions can be inherited or caused by a spontaneous gene mutation or an imbalance in a child’s immune system.
Symptoms, Diagnosis and Outlook
The symptoms of pediatric neuromuscular disorders vary according to the type of disorder and the areas it affects. Some signs of pediatric neuromuscular conditions may begin in infancy. Others may not appear until childhood or adolescence.
Common symptoms of pediatric neuromuscular disorders include:
- Balance problems
- Delayed milestones that involve movement, such as crawling, walking or abnormal gait
- Involuntary muscle rippling or twitching
- Muscle weakness or atrophy
- Numbness or tingling
- Poor muscle tone
Diagnosing pediatric neuromuscular disorders typically begins with a physical examination that evaluates your child’s muscle strength and reflexes.
Additional testing may include:
- Blood tests
- Electromyogram (EMG) nerve conduction studies
- Imaging tests, such as computed tomography (CT), positron emission tomography (PET) or magnetic resonance imaging (MRI) scans
- Muscle biopsy
- Lumbar puncture (LP), also called a spinal tap
There is currently no cure for pediatric neuromuscular disorders. Treatment focuses on delaying the progression of the disease and maintaining your child’s quality of life. Children who are encouraged to develop coping skills and experience a supportive atmosphere from family and friends can lead independent, productive lives.
