16729 Amyotrophic Lateral Sclerosis Als

Overview

Amyotrophic lateral sclerosis (ALS) is a rare disease that damages nerve cells in the brain and spinal cord. These nerves control the muscles you use to move, speak, breathe, and swallow. Over time, ALS makes these muscles weak and hard to use. It is also called Lou Gehrig's disease or motor neurone disease.

No, ALS is rare. Around 2 in every 100,000 people are diagnosed with it each year.

ALS can affect adults at any age, but it is most often diagnosed between ages 55 and 75. It is slightly more common in men than women.

Symptoms

Common symptoms

• Muscle weakness in your hands, legs, or feet
• Tripping or dropping things more often
• Slurred speech or trouble forming words
• Trouble chewing, swallowing, or managing saliva
• Muscle twitching or cramps
• Fatigue and tiredness

Causes

Main causes

• The exact cause of ALS is not fully understood.
• In most people, ALS happens without a clear reason.
• In a small number of people, the disease runs in families due to gene changes.

Risk factors

• Being over age 55
• Being male
• Having a close family member with ALS
• Smoking

When to see a doctor

See a doctor urgently if:

• If you are having trouble swallowing, breathing, or choking, seek care the same day.

Book a routine appointment if:

• If you notice ongoing muscle weakness, twitching, slurred speech, or difficulty using your hands, legs, or feet, make an appointment with your GP.

Diagnosis

There is no single test for ALS. A specialist (neurologist) will ask about your symptoms, examine you, and run tests to rule out other conditions that can look like ALS.

Tests that may be done

• Blood and urine tests
• Nerve conduction studies to check how well nerves send signals
• Electromyography (EMG), a test of muscle electrical activity
• MRI scan of the brain and spinal cord
• Sometimes a lumbar puncture to test spinal fluid

What to expect at your appointment

The diagnosis process can take weeks or months. Your care team will explain each test and support you through the process. Ask questions whenever you feel unsure.

Treatment

Treatment for ALS focuses on managing symptoms, keeping you comfortable, and helping you stay as active as possible for as long as possible. You will have a team of health professionals working with you, including your GP, a neurologist, nurses, physiotherapists, speech and language therapists, and dietitians.

Self-care at home

• Maintain a balanced diet and ask for help if swallowing becomes hard.
• Stay as active as your body allows, with rest when needed.
• Use aids like walkers, wheelchairs, or speech devices if they help.
• Join a support group to connect with others who understand.

Medical treatments

Medicines can help with symptoms such as muscle cramps, excess saliva, or mood changes. Some treatments may slow the progress of the disease. Devices to support breathing, such as non-invasive breathing support, can also be used. Always discuss your options with your specialist doctor.

When is surgery considered?

Surgery is not a common treatment for ALS. Rarely, a feeding tube may be placed to help with nutrition, or a breathing tube (tracheostomy) may be needed in advanced stages. Your care team will guide you through these decisions.

Living with this condition

ALS changes daily life, but many people adapt and find new ways to do things they enjoy. Plan tasks, pace yourself, and ask friends or family for help when you need it.

Lifestyle tips

• Rest when you feel tired.
• Stay connected with loved ones.
• Keep your home safe and easy to move around.
• Consider using assistive technology for communication, like speech-to-text apps or eye-tracking devices.

Diet and exercise

Eating well becomes even more important. If swallowing is difficult, a speech and language therapist can suggest softer foods or thickened drinks. Gentle exercise, such as stretching or range-of-motion movements, can help keep joints flexible and muscles comfortable.

Mental health and emotional wellbeing

A diagnosis of ALS can bring sadness, anxiety, fear, or anger. These feelings are normal. Talking with a counsellor or joining a support group can make a real difference.

Prevention

There is no known way to prevent ALS. Because the cause is largely unknown, there are no specific prevention steps. Living a healthy lifestyle is always good, but it will not guarantee protection from ALS.

Complications

If left untreated

• Weakness of the muscles used for breathing, leading to lung infections or respiratory failure.
• Malnutrition and dehydration from swallowing difficulties.
• Choking or food going into the lungs.
• Falls and injuries.
• Loss of speech, making communication harder.

Long-term outlook

ALS is a serious condition, and it usually progresses over a few years. However, every person is different, and some live many years with the help of treatments and support. Your care team will work with you to maintain comfort, dignity, and quality of life.
