Summary
Transcranial magnetic stimulation effectively detects motor pathway changes in pediatric multiple sclerosis (MS). Findings suggest altered motor neuron excitability and demyelination, with less apparent axonal damage in pediatric MS patients.
Area of Science:
- Neuroscience
- Pediatric Neurology
- Clinical Electrophysiology
Background:
- Multiple sclerosis (MS) is a demyelinating disease affecting the central nervous system.
- Understanding motor pathway involvement in pediatric MS is crucial for diagnosis and management.
Purpose of the Study:
- To evaluate the involvement of motor pathways in children diagnosed with multiple sclerosis.
- To assess the utility of transcranial magnetic stimulation (TMS) in pediatric MS.
Main Methods:
- Utilized transcranial magnetic stimulation (TMS) to assess motor pathways.
- Enrolled 9 children with relapsing-remitting MS (mean disease duration 1.68 years) and 20 healthy controls.
Main Results:
- Abnormal findings were prevalent in the pediatric MS group.
- Polyphasic changes in motor evoked potentials (MEP) shape occurred in 78% of cases.
- Elevated MEP threshold was observed in 88% of pediatric MS patients.
Conclusions:
- TMS exhibits high sensitivity for detecting abnormalities in pediatric MS.
- Neurophysiological findings suggest altered membrane excitability and demyelination in motor neurons.
- Axonal damage appears less prominent in children with MS compared to other findings.

01:11Direct Motor Pathways
4.7K
The direct motor pathways, also known as the pyramidal tracts, are a group of neural pathways that originate in the brain and descend through the spinal cord. They control the voluntary movement of the body. There are two major direct motor pathways: the corticospinal and the corticobulbar tracts.
The corticospinal tract is responsible for the voluntary movement of the limbs and trunk. It originates in the cerebral cortex of the brain and descends through the cerebrum's internal capsule and...

Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...

01:22Indirect Motor Pathways
3.4K
The indirect motor or extrapyramidal pathways originate in the brainstem, the lower portion of the brain that connects it to the spinal cord. They consist of several distinct tracts, each with specialized functions. The four main tracts of the indirect motor pathways are the vestibulospinal tract, the reticulospinal tract, the tectospinal tract, and the rubrospinal tract.
The vestibulospinal tract originates in the vestibular nuclei of the brainstem. The vestibular system detects changes in...

Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...

01:28Major Somatic Sensory Pathways
3.2K
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the...

01:29Overview of Somatic Sensory Pathways
9.9K
Somatic sensory or somatosensory pathways refer to the neural pathways that carry information related to touch, pressure, pain, temperature, and proprioception from the skin, muscles, tendons, and joints to the brain. These pathways involve several stages of processing and integration of sensory information.
The somatosensory system is divided into three main pathways: the dorsal (or posterior) column-medial lemniscus, spinothalamic (or anterolateral), and spinocerebellar pathways.
