Paralysis facts for kids
Paralysis is when a part of your body cannot move. It happens because the muscles in that area have completely lost their ability to work. This means you cannot control or move that specific body part.
Paralysis often happens because of damage to the nervous system or brain. The spinal cord, which carries messages between your brain and body, is a common place for this damage. When these messages can't get through, muscles don't receive the signals they need to move. Sometimes, people with paralysis also lose the ability to feel things in the affected area.

What Causes Paralysis?
Many things can cause paralysis. It usually involves damage to the brain or spinal cord. Here are some common causes:
Common Causes of Paralysis
- Stroke: This happens when blood flow to part of the brain is stopped. Brain cells can die, leading to paralysis on one side of the body.
- Injury: Accidents or falls can cause serious damage to the spinal cord. This can stop messages from traveling between the brain and muscles.
- Poliomyelitis (Polio): This is a serious disease caused by a virus. It attacks the nervous system and can lead to paralysis. Thanks to vaccines, polio is now rare in many parts of the world.
- Amyotrophic Lateral Sclerosis (ALS): Also known as Lou Gehrig's disease, ALS is a condition where nerve cells that control muscles slowly die. This leads to muscles weakening and eventually becoming paralyzed.
- Botulism: This is a rare but serious illness caused by toxins from certain bacteria. These toxins can block nerve signals to muscles, causing paralysis.
- Spina Bifida: This is a birth defect where the spinal cord does not form completely. It can lead to paralysis in the legs and other problems.
- Multiple Sclerosis (MS): In MS, the body's immune system attacks the protective covering of nerves. This can disrupt nerve signals, leading to problems with movement and sometimes temporary or permanent paralysis.
- Guillain-Barré Syndrome: This is a rare condition where the immune system attacks healthy nerve cells. It can cause weakness and tingling that can progress to paralysis. Most people recover from this condition.
Temporary Paralysis
Sometimes, paralysis can be temporary. For example, during the REM stage of sleep, your body naturally becomes partly paralyzed. This stops you from acting out your dreams. This is a normal and healthy part of sleep. If you wake up during this stage and can't move, it's called Sleep paralysis. It can be scary but usually lasts only a few seconds or minutes.
Types of Paralysis
Paralysis can affect different parts of the body. Doctors often describe it based on which limbs are affected.
Monoplegia
Monoplegia is when only one limb is paralyzed. This could be one arm or one leg. It is often caused by damage to a specific nerve or a small area of the brain.
Hemiplegia
Hemiplegia means one side of the body is paralyzed. This usually affects an arm and a leg on the same side. A stroke is a common cause of hemiplegia.
Paraplegia
Paraplegia is when both legs are paralyzed. It often happens due to damage to the spinal cord in the middle or lower back. People with paraplegia may use a wheelchair to move around.
Quadriplegia
Quadriplegia (also called tetraplegia) is the most severe type. It means all four limbs (both arms and both legs) are paralyzed. This is usually caused by serious damage to the spinal cord in the neck area.
Living with Paralysis
Living with paralysis can be challenging, but many people learn to adapt. Modern medicine and technology offer many ways to help.
Rehabilitation and Support
- Physical Therapy: This helps people strengthen muscles that still work and learn new ways to move.
- Occupational Therapy: This focuses on daily activities like dressing, eating, and writing. Therapists help people find tools and methods to do these tasks independently.
- Assistive Devices: Wheelchairs, braces, and other devices can help people with paralysis move around and do everyday tasks.
- Technology: New technologies, like robotic aids and brain-computer interfaces, are being developed to help people regain movement or control devices with their thoughts.
Support from family, friends, and support groups is also very important. Many organizations help people with paralysis live full and active lives.
