Paralysis: What is it, Diagnosis, Management & Prevention

Throughout the world, millions of individuals have paralysis. It is the loss of the ability to move the muscles voluntarily in one or more areas of the body, usually due to nerve injury.

Paralysis can substantially impact a person’s quality of life, which can affect their physical, mental, and emotional health. This blog post will delve into the causes, symptoms, management, and prevention of paralysis and the variables that contribute to it. 

What causes paralysis?

The brain, spinal cord and the nerves that link them to the rest of the body comprise the nervous system.

All bodily processes, including movement, sensation, thought, and emotion, are under the nerve system’s control.

When the nervous system is harmed, it can interfere with the brain’s ability to communicate with the muscles, leading to paralysis.

Stroke

When a blood vessel in the brain is clogged or torn, it deprives the brain tissue of oxygen and nutrients, which results in a stroke. Brain cells may die as a result, impairing the functions they regulate.

Depending on which part of the brain is damaged, a stroke can cause paralysis on one side of the body (hemiplegia), both sides of the body (diplegia), or all four limbs (quadriplegia).

A stroke must be treated immediately as a medical emergency to reduce brain damage and speed recovery.

Spinal cord injury

A spinal cord injury is a disorder caused due to damage in the spinal cord, a network of nerves that runs from the brain to the lower back.

These communications can be interrupted or blocked by a damaged spinal cord, which can lead to paralysis below the site of the lesion.

The higher the level of injury, the more extensive the paralysis. For example, an injury in the neck can cause quadriplegia, while an injury in the lower back can cause paraplegia.

Multiple sclerosis

The myelin sheath, a protective covering for nerve fibres, is inflamed and harmed by the autoimmune illness known as multiple sclerosis (MS). The myelin coating facilitates the more rapid and effective transmission of nerve messages. 

When damaged, nerve signals can slow down or stop, causing symptoms such as weakness, numbness, tingling, vision problems, and paralysis.

Cerebral palsy

A collection of conditions called cerebral palsy (CP) affect posture, muscle tone, balance, and mobility. Before, during, or soon after birth, the brain experiences aberrant growth or injury that results in cerebral palsy. The brain impairment impacts the brain’s ability to regulate muscular movement and coordination. 

Bell’s palsy

The disorder known as Bell’s palsy results in momentary weakening or paralysis of the muscles on one side of the face. The facial nerve, which regulates facial expressions and movements, is irritated or compressed, which results in the condition.

The exact cause of Bell’s palsy is unknown, but it may be related to viral infections or immune system disorders. Bell’s palsy usually resolves within a few weeks or months without treatment.

How is paralysis diagnosed?

Physical examination results and medical history are typically used to diagnose paralysis.

Depending on your symptoms and the suspected cause of paralysis, you may need additional tests to confirm your diagnosis and determine the extent and location of nerve damage. These tests may include:

X-rays: X-rays provide images of the interiors of your body’s bones and organs using electromagnetic radiation. Your body’s joints or spine could have degenerative changes, tumours, infections, fractures, or dislocations that could cause paralysis.

CT scan: A CT scan combines a computer and many X-rays to produce in-depth cross-sectional images of your body. When it comes to anomalies in your bones, soft tissues, blood vessels, or organs, it results in paralysis.

MRI scan: A powerful radio waves and magnetic field waves are used in an MRI scan to create sharp images of your body. Your brain, spinal cord, nerves, muscles, and other tissues that could result in paralysis can all be seen on an MRI scan.

Electromyography (EMG) and nerve conduction studies: The NCS and EMG examinations evaluate the electrical activity of your muscles and nerves. EMG involves inserting thin needles into your muscles and recording the electrical signals they produce when you contract them.

NCS involves attaching electrodes to your skin and stimulating your nerves with small electric shocks. These tests can help determine if your paralysis is caused by damage to your muscles or nerves and where the damage is located.

Blood tests: Blood tests can check for signs of infection, inflammation, or other conditions that could cause paralysis. For example, blood tests can detect antibodies to specific viruses, bacteria or markers of autoimmune diseases.

How is paralysis managed or treated?

Permanent paralysis cannot be cured, but some therapies and treatments can help you function better, be more independent, and live a higher-quality life. 

The type and intensity of treatment will depend on the cause, extent, and location of your paralysis, as well as your goals and preferences. Some of the common treatments and therapies for paralysis include:

Medications

Medications can help treat some underlying causes or complications of paralysis, such as infections, inflammation, pain, spasticity, depression, or anxiety. Depending on your condition, you may need to take medications orally, by injection, or by infusion.

Surgery

Surgery can help repair some of the damage caused in the nervous system or relieve some of the pressure on your nerves that could cause paralysis. For example, surgery can remove blood clots or tumours from your brain or spinal cord, decompress a pinched nerve, fuse broken vertebrae, or implant devices that stimulate your nerves or muscles.

Physical therapy

Physical therapy contains movements and exercises that help you build muscle strength, increase your range of motion, and guard against problems, including contractures (permanent muscle shortening), pressure sores (skin ulcers) and blood clots.

You can learn how to use assistive devices like braces, splints, walkers, wheelchairs, or prosthetics with the help of physical therapy.

Occupational therapy

Occupational therapy involves activities that help you perform daily tasks such as dressing, bathing, eating, working, or leisure. Occupational therapy can also help you adapt your home or work environment to suit your needs and abilities.

Speech therapy

Speech therapy involves exercises and techniques that help you communicate better if you have difficulty speaking or swallowing due to facial paralysis or brain damage. You can employ technologies that produce speech or alternate forms of communication like sign language with the aid of speech therapy.

Psychotherapy 

Speaking with a mental health practitioner during psychotherapy can help you manage the psychological and emotional repercussions of paralysis. 

Psychotherapy can assist you in overcoming tension, anxiety, despair, grief, anger, or low self-esteem caused by your disease.

Psychotherapy can also help you adjust to the changes in your life and relationships due to paralysis.

How can paralysis be prevented?

Some causes of paralysis, such as congenital flaws or genetic illnesses, cannot be avoided. The following advice will help you lower your risk of having paralysis due to other causes:

• Eat a balanced diet that provides adequate nutrients for your nervous system.
• Maintain your cardiovascular and muscle fitness with frequent exercise.
• Quit smoking and limit alcohol consumption to avoid damaging your blood vessels and nerves.
• Avoid strokes and other cardiovascular illnesses, maintain a healthy weight and blood pressure.
• Manage chronic conditions such as diabetes or high cholesterol that could affect your nervous system.
• Avoid exposure to toxins or infections that could harm your nervous system.
• Wear a helmet and protective gear when engaging in sports or recreational activities that could cause head or neck injuries.
• Use caution when diving into shallow water or swimming in unfamiliar places to avoid spinal cord injuries.

Summary

Throughout the world, millions of individuals have paralysis. Due to nervous system impairment, it is the loss of voluntary muscular action in one or more body regions. Paralysis can substantially negatively impact a person’s quality of life, which can affect their physical, mental, and emotional well-being.

Paralysis can have many possible causes, depending on which part of the nervous system is affected. The most common causes are spinal cord injury, stroke, multiple sclerosis, cerebral palsy, and Bell’s palsy.

There is no cure for permanent paralysis, but there are treatments and therapies that can help improve function, independence and quality of life. These include medications, surgery, physical therapy, occupational therapy, speech therapy, and psychotherapy.
