Understanding Paralysis: Types, Causes, and Insights

Image
  Paralysis is the loss of muscle function in part or all of the body, often caused by damage to the nervous system. It can result from conditions like stroke, spinal cord injury, traumatic brain injury, multiple sclerosis, or cerebral palsy. Other causes include infections (e.g., polio), autoimmune diseases (e.g., Guillain-Barré syndrome), or nerve damage from trauma or tumors.   Types include: - **Monoplegia**: One limb affected. - **Hemiplegia**: One side of the body affected. - **Paraplegia**: Lower body (usually legs) affected. - **Quadriplegia**: All four limbs and torso affected.   Symptoms range from partial to complete loss of movement and sensation, depending on the cause and severity. Treatment focuses on addressing the underlying cause, managing symptoms, and improving quality of life through physical therapy, medications, or assistive devices. In some cases, like stroke-related paralysis, recovery is possible with rehabilitation, though outcom...

What is Guillain-Barré Syndrome? Symptoms, Causes & Treatment

Image
  Guillain-Barré Syndrome (GBS) is a rare but serious neurological disorder where the body’s immune system mistakenly attacks the **peripheral nervous system**—the nerves outside the brain and spinal cord. This attack damages the nerves or their protective covering (myelin), disrupting signals between the brain and body. The result can range from mild muscle weakness to severe paralysis.   - **Cause**: The exact cause isn’t fully understood, but GBS often follows a bacterial or viral infection. Common triggers include:   - *Campylobacter jejuni* (a bacteria linked to undercooked poultry)   - Respiratory infections (like the flu)   - Gastrointestinal infections   - Viruses such as Epstein-Barr, cytomegalovirus, or Zika - **Other Triggers**: Rarely, GBS has been linked to recent surgeries, certain vaccinations (though the risk is extremely low, about 1-2 cases per million), or cancers like lymphoma.   ---   ### Symptoms GBS s...
