Understanding Paralysis
Paralysis is a complex condition that significantly impacts a person's physical abilities and daily life. It can arise from various causes and profoundly affect an individual's independence and wellbeing.
Causes of Paralysis
Spinal cord injuries are a leading cause of paralysis, often resulting from accidents or falls. These injuries disrupt the communication between the brain and body parts below the injury site.
Neurological disorders like amyotrophic lateral sclerosis (ALS) can progressively damage motor neurons, leading to paralysis. Strokes may cause paralysis by damaging brain areas controlling movement.
Other causes include:
Multiple sclerosis
Cerebral palsy
Guillain-Barré syndrome
Certain infections, tumors, and genetic conditions can also result in paralysis. The extent and location of paralysis depend on the specific cause and affected area of the nervous system.
