Paralysis Types symptoms and treatment

Paralysis: Types, symptoms, and treatment, As a result of nerve injury, paralysis is the loss of voluntary muscle function in one or more bodily parts.

The nervous system has two parts:

  • the central nervous system (CNS), which includes the brain and spinal cord.
  • the peripheral nervous system (PNS), which contains the nerves outside of the CNS

The PNS’s neurons, or nerve cells, have a variety of jobs to do.

For instance, motor neurons control how muscles move. The CNS receives information from sensory neurons, such as that pressure, pain, and temperature.

When damage to the nerves, spinal cord, or brain interrupts the flow of nerve signals, paralysis results.

According to the following characteristics, doctors define paralysis:


The severity of paralysis depends on how much muscle function has been lost.

Paresis, or partial paralysis, results in severe muscle weakness and restricted movement. Paresis patients do, however, have some residual control over the afflicted muscles.

When a person is completely paralyzed, they are unable to move the injured body part.


Duration is the length of time that the paralysis lasts.

Some medical diseases, including Bell’s palsy, stroke, and sleep paralysis, can result in momentary paralysis. People can eventually regain full or partial control over the damaged muscles.

Periodic paralysis caused by hyperkalemia or hypokalemia is another ailment that may momentarily create the issue. They develop as a result of mutations in the SCN4A or CACNA1S genes.

The proteins that convey sodium and calcium ions into and out of muscle cells are made according to instructions carried by these genes. Ion transport within muscle cells aids in the contraction and movement of the muscle.

Ion flow disruptions can occasionally cause paralysis and muscle weakness.

While neuromuscular disorders and serious head or neck injuries can result in permanent paralysis.


A small portion of the body, such as the face, hands, or feet, may have localized paralysis.

The effects of generalized paralysis are more widespread and extend to other bodily areas.

various kinds of paralysis

  • Monoplegia: This affects one area, such as one arm or leg.
  • Hemiplegia: This affects one arm and one leg on the same side of the body.
  • Paraplegia: Also called lower body paralysis, this affects both legs and sometimes the hips and organs in the lower abdomen.
  • Quadriplegia: This affects both arms and legs, and sometimes muscles in the trunk, the functions of internal organs, or both.

Muscle tension

Lower motor neurons that activate skeletal muscle action are harmed by flaccid paralysis. The muscles atrophy or shrink with time.

According to the Centers for Disease Control and Prevention (CDC)Trusted Source, flaccid paralysis is a frequent polio consequence.

Other reasons include Guillain-Barré syndrome, a rare autoimmune condition in which the PNS is attacked by the immune system, and spinal cord inflammation, also known as myelitis.

Muscle stiffness, uncontrollable spasms, and muscle weakening are symptoms of spastic paralysis. This type of paralysis can be brought on by stroke, inherited spastic paraplegia, ALS, spinal cord injury, or amyotrophic lateral sclerosis (ALS).


Depending on the nature and origin of the problem, symptoms can differ. The lack of muscle function in one or more body parts is the most typical paralysis symptom.

Other signs and symptoms of paralysis include:

  • numbness or pain in the affected muscles
  • muscle weakness
  • visible signs of muscle loss (muscle atrophy)
  • stiffness
  • involuntary spasms or twitches


The following are the most typical causes of paralysis in the US, as reported by the 2013 U.S. Paralysis Prevalence and Health Disparities SurveyTrusted Source:

  • stroke
  • spinal cord injury
  • cerebral palsy
  • multiple sclerosis

Any of the health issues mentioned above have the potential to induce nervous system injury, which leads to muscle weakness and paralysis.

The brain and the rest of the body communicate with each other via a healthy neural system. Peripheral nerves all across the body receive brain signals that pass down the spinal cord.

The peripheral nerves control a wide range of processes, including:

  • automatic functions, such as breathing and digestion
  • voluntary muscle movements, such as walking and chewing
  • sensory functions, such as pain, temperature, and pressure detection

Any element of the nervous system that is damaged might have serious consequences for a person’s general health and quality of life.

Other potential causes of nervous system harm and the ensuing paralysis or weakening of muscles include:

  • brain or spinal cord tumors
  • infections, such as meningitis, encephalitis, and polio
  • spina bifida, or the incomplete development of the brain, spine, or spinal cord
  • motor neuron diseases, such as ALS and primary lateral sclerosis
  • autoimmune diseases, including Guillain-Barré syndrome and lupus
  • inherited disorders, including spinal muscular atrophy and hypo- or hyperkalemic partial paralysis

Tick paralysis

Certain tick species can create neurotoxins that induce muscle weakness and sudden foot paralysis in people.

The neurotoxins’ effects progressively ascend the body.

After the tick is removed, the majority of patients recover fully. But if left untreated, tick paralysis eventually results in respiratory failure.


There is currently no treatment for paralysis. However, some patients have partial or full healing, depending on the nature and source of the problem.

Without medical intervention, temporary paralysis brought on by Bell’s palsy or a stroke may resolve on its own.

A person may also regain some muscle control when paralysis comes from a spinal cord injury or a long-term neurological disorder.

Although rehabilitation does not completely cure paralysis, it can help keep symptoms from getting worse.

Among the available remedies are:

  • physical therapy
  • occupational therapy
  • mobility devices, such as braces, walkers, and wheelchairs
  • medications
  • surgical amputation
  • nerve transfer surgery

Emotional and social support can also play vital roles in a person’s treatment.


The loss of movement in one or more body parts, whether temporary or permanent, is referred to as paralysis.

Many paralyzed persons never fully regain their sensation or motion in the paralyzed area. The quality of life can be enhanced by physical treatment, mobility aids, and social and emotional support.

Surgery and medication are frequently beneficial as well. The degree of a patient’s paralysis and its underlying cause will determine the best course of treatment.
