15345 Paralysis

Overview

Paralysis is when you lose the ability to move a part of your body. It happens because of a problem with the nerves that send messages between your brain and your muscles. The loss of movement can be complete (you cannot move that part at all) or partial (you have some weakness but some movement remains). Paralysis can affect one arm or leg, one side of the body, or both legs. In some cases, it can affect the muscles that help you breathe.

Paralysis is not rare, but the exact number of people affected depends on the cause. Strokes are a leading cause of paralysis in adults, and spinal cord injuries affect many people each year. In the UK, there are thousands of new cases every year, but the overall number of people living with paralysis is significant.

Paralysis can affect anyone at any age. It can happen in babies because of birth injuries or conditions present from birth. It can affect children and young people because of accidents or infections. It is more common in older adults, especially because stroke risk increases with age. But the underlying cause of your paralysis is unique to you, and your doctor will assess your specific situation.

Symptoms

Common symptoms

• Inability to move one or more muscles, such as an arm, leg, or the muscles of the face
• Weakness in a part of the body that makes it hard to move
• Numbness or a 'pins and needles' feeling in the affected area
• Loss of feeling to touch, temperature, or pain in the affected area
• Muscle stiffness or spasm (involuntary tightening of muscles)
• Difficulty with coordination or balance

Symptoms in children

• Delays in reaching developmental milestones, such as rolling over, sitting up, or walking
• Weakness that a parent notices, such as one side of the body seeming less active than the other
• An unusual walking pattern, like dragging a foot or toe walking
• Stiff or floppy muscles in the arms or legs
• Difficulty with fine motor skills, like holding a crayon or doing up buttons

Symptoms in older adults

• Sudden weakness on one side of the face, arm, or leg that may come and go
• Difficulty speaking or understanding speech, sometimes with weakness
• A gradual increase in weakness that makes daily tasks harder
• Loss of balance or falls that are not due to just 'getting older'
• Changes in bladder or bowel control that are new

Causes

Main causes

• Stroke – a blockage or bleeding in the brain that damages the nerve cells that control movement
• Spinal cord injury – damage to the bundle of nerves that runs down your back, often from a fall, car accident, or sports injury
• Multiple sclerosis (MS) – a condition where the body's immune system attacks the protective covering of nerves
• Cerebral palsy – a condition caused by brain damage before or during birth that affects movement and posture
• Guillain-Barré syndrome – a rare condition where the immune system attacks the nerves, often after an infection
• Infections that affect the brain or spinal cord, such as meningitis or encephalitis

Risk factors

• High blood pressure, smoking, diabetes, and high cholesterol increase the risk of stroke
• Participating in contact sports without proper safety gear can increase the risk of spinal cord injury
• Age – the risk of stroke and some nerve conditions rises with age
• A family history of certain neurological conditions, such as multiple sclerosis
• Weakened immune system or a recent infection can increase the risk of some nerve conditions
• Being born prematurely can increase the risk of cerebral palsy

When to see a doctor

See a doctor urgently if:

• If you have sudden weakness, numbness, or paralysis in any part of your body, seek medical care without delay — even if the symptoms go away. This could be a warning sign of a stroke or other serious condition.
• If you have difficulty speaking, breathing, or seeing, call your local emergency number immediately.
• If you have back pain with weakness or numbness in your legs, or loss of bladder or bowel control, see a doctor right away.

Book a routine appointment if:

• If you have gradual weakness or numbness that is not getting better, or that is affecting how you walk, use your hands, or do everyday tasks, make an appointment with your GP.
• If you have already been diagnosed with a condition like multiple sclerosis and you notice new or worsening symptoms, contact your specialist or GP.
• If you have concerns about your child's development, such as delayed walking or weakness, talk to a health visitor or GP.

Diagnosis

Your doctor will start by asking about your symptoms, your medical history, and any recent injuries or illnesses. They will perform a physical examination to check your muscle strength, reflexes, and ability to feel touch, pain, and temperature. Depending on your symptoms, they may refer you to a specialist, such as a neurologist (a doctor who treats the nervous system) or a physiotherapist.

Tests that may be done

• Imaging scans such as a CT scan or MRI scan of the brain or spine to look for stroke, injury, or other changes
• Nerve conduction studies and electromyography (EMG) to see how well your nerves and muscles are working
• Blood tests to check for infections, vitamin deficiencies, or conditions like diabetes that can affect nerves
• A lumbar puncture (spinal tap), which involves taking a small sample of fluid from around the spinal cord, to look for signs of multiple sclerosis or infection

What to expect at your appointment

The tests you have will depend on your specific symptoms and what your doctor suspects. Some tests are quick and painless, while others take a little time. You may need to see more than one specialist as part of your diagnosis. It is normal to feel anxious, so ask your doctor to explain why each test is needed and what the results might mean. You should receive a clear explanation of the next steps after your results are reviewed.

Treatment

There is no single cure for paralysis, but treatment focuses on finding the underlying cause, preventing further damage, and helping you regain as much function as possible. Treatment is usually a team effort. Your healthcare team may include doctors, nurses, physiotherapists, occupational therapists, speech and language therapists, and mental health professionals. The plan will be tailored to your individual needs and the cause of your paralysis.

Self-care at home

• Follow your rehabilitation plan — attend therapy sessions and practice the exercises they give you at home.
• Take care of your skin — if you cannot feel a part of your body, check it daily for redness, pressure sores, or injuries.
• Keep moving your joints that are not paralyzed to prevent stiffness, or ask someone to help you move them gently.
• Use mobility aids as recommended, such as a walker, cane, wheelchair, or braces.
• Eat a healthy diet and stay as active as you safely can to maintain your overall health.
• Ask for help with daily tasks like bathing, dressing, and eating if you need it — this is a normal part of recovery.

Medical treatments

Medical treatments for paralysis vary depending on the cause. For example, if a stroke is the cause, doctors may focus on preventing another stroke by managing blood pressure and cholesterol. If an infection is causing the paralysis, treatment may include antiviral or antibiotic medicines (these are prescribed by a doctor, and the exact medicine will depend on your situation). For long-term nerve conditions, treatments may include medicines to help with nerve pain, spasticity (muscle tightness), or bladder control. In some cases, doctors may use steroid medicines to reduce inflammation around the spinal cord or brain. Your doctor will explain the options that are right for you and will not recommend a specific medicine without considering your health history.

When is surgery considered?

Surgery is not needed for most cases of paralysis, but it may be an option if there is a structural problem that can be fixed. For example, surgery may be needed to relieve pressure on the spinal cord from a herniated disc, to remove a tumour that is pressing on nerves, or to stabilize a badly injured spine after an accident. If surgery is possible for your situation, your surgeon will discuss the benefits, risks, and what recovery might involve.

Living with this condition

Living with paralysis means adapting the way you do everyday things. This can feel overwhelming at first, but many people adjust with the help of therapists and support networks. You may need to transform your home so that it is accessible, such as adding ramps, widening doorways, or installing grab rails in the bathroom. An occupational therapist can help you find practical solutions for eating, dressing, bathing, and moving around your home. Over time, these routines can become new habits.

Lifestyle tips

• Stay connected with family and friends — they can be a source of emotional and practical support.
• Pace yourself and rest when you need to. Progress may be slow, and that is okay.
• Set realistic goals for your recovery and celebrate small improvements.
• Join a local or online support group for people living with paralysis or a specific condition like stroke or spinal cord injury.
• Talk to a counsellor or psychologist if you feel anxious, low, or overwhelmed.

Diet and exercise

Eating a balanced diet helps keep your body strong and prevents complications like weight gain, constipation, and pressure sores. Include plenty of fruits, vegetables, wholegrains, and lean proteins. Your doctor or dietitian can give you advice if you have specific dietary needs. Exercise is also important, even if you cannot move certain parts of your body. A physiotherapist can design a safe exercise programme that may include passive movements (where someone moves the limb for you), stretching, strengthening any weak muscles, and cardio exercises that do not put you at risk. Always check with your healthcare team before starting any new exercise.

Mental health and emotional wellbeing

Paralysis can have a deep emotional impact. It is normal to feel grief, frustration, anger, or sadness about the changes in your body. These feelings can be made worse by the loss of independence and social isolation. You do not have to manage this alone. It is important to talk about your feelings with your doctor, a psychologist, or a trusted support line. If you are having thoughts of self-harm or despair, please reach out for crisis support immediately — in the UK, you can call Samaritans free on 116123 (or your local crisis helpline). You deserve to be heard and supported.

Prevention

Not all causes of paralysis can be prevented, but some of the most common causes can be. Reducing your risk of stroke is a major step. This includes managing blood pressure, keeping blood sugar levels healthy, eating a diet low in salt and saturated fat, being physically active, stopping smoking, and limiting alcohol. You can also help prevent spinal cord injuries by wearing seatbelts, using appropriate protective gear in sport, and avoiding risky behaviours like diving into shallow water.

Complications

If left untreated

• Pressure sores — skin breakdown can happen when you stay in one position and cannot feel or move the skin, especially in the back, hips, and heels.
• Blood clots in the legs or lungs, which can form when you are immobile for a long time.
• Muscle contractures — muscles and joints can become permanently tightened and shortened if not moved regularly.
• Urinary tract infections or kidney problems, especially if you have bladder weakness or use a catheter.
• Deep depression or anxiety, which can affect your recovery and quality of life if not addressed.

Long-term outlook

The outlook for paralysis varies greatly. Some people make a full or near-full recovery, especially when the cause is treated early and rehabilitation is intensive. Others may live with permanent paralysis, but they can still live a meaningful and active life with the right support, equipment, and mindset. Many people find new strengths, hobbies, and purposes after a diagnosis of paralysis. Medical and technological advances — such as better wheelchairs, smart home devices, and new rehabilitation techniques — continue to improve possibilities. Your healthcare team will focus on what you can do, not just what you cannot, and will support you to make the most of your abilities.
