You can feel tired after many things like exercise, a bad night’s sleep or mental effort. Tiredness usually goes away with rest.
However, fatigue happens without the effort of any activity and does not improve with rest.
Fatigue has been described as an overwhelming sense of tiredness, a lack of energy and a feeling of exhaustion. It is more than a one-off feeling of tiredness that will go away after sleeping well.
Anyone can feel fatigued when they are working too hard, or when pressures at work or at home cause stress. But fatigue can also be a specific symptom of a medical condition such as Parkinson’s.
Up to half of people with Parkinson’s say they experience fatigue.
People who are newly diagnosed with Parkinson’s are just as likely to experience fatigue as those who have had the condition for some time. In fact, it may be one of the earliest symptoms you have.
The effects of fatigue and Parkinson’s vary from person to person. They can change from day-to-day or even hour-to-hour.
You may feel quite fit and able one day and then too fatigued to do much the following day. This might be because things that came naturally before your diagnosis now take more effort. If you are working for example, you may feel much more exhausted in the evenings than you used to and you may not want to do anything else.
Many people with Parkinson’s experience fatigue but it’s common in people with other long-term physical health conditions too. We don’t yet fully understand what causes it in Parkinson’s but it may be because of chemical changes in the brain.
Fatigue in Parkinson’s can also be related to other symptoms of the condition.
- For example, you may feel energetic and capable of doing everyday jobs at certain times of the day, but not at others. This may sometimes be related to the timing and dosage of your medication.
- Tremor, stiffness or involuntary movements that some people with Parkinson’s experience may put stress on your muscles. It means they work harder and often against each other to move or complete a task. This means they can become fatigued quickly.
- If you experience slowness of movement (bradykinesia), tasks will take you longer to complete than they used to, leading to fatigue.
- Parkinson’s and its symptoms can cause stress at work or home and this can make fatigue worse. This is particularly true if stress builds up over time.
It’s also important to remember that mental fatigue can be just as difficult to manage. Some people may find it hard to concentrate for a long time without a break. For example, this may cause problems if you are still in work.
Although it’s natural to associate any health problems with Parkinson’s, there are other causes of fatigue that are unrelated. These may include treatable conditions such as thyroid problems, vitamin deficiencies, anaemia and diabetes.
Because of this, you should discuss any feelings of fatigue with your GP, specialist or Parkinson’s nurse. Together, you can look at the possible cause and discuss treatment options.
Fatigue can sometimes be overlooked by doctors, but it’s important that it is managed properly.
If your feelings of fatigue are related to other Parkinson’s symptoms, such as tremor, stiffness or involuntary movements, they may be helped with Parkinson’s medication. This will also help you manage your symptoms better, so you have more energy to do things that may otherwise be difficult.
However, remember that fatigue in Parkinson’s may not be related simply to these symptoms.
Also, Parkinson’s medication is not always successful at treating fatigue. In some cases, non-drug treatments may work better. One example is cognitive behavioural therapy (CBT) which is a type of talking therapy. This can help you manage fatigue practically by focusing on what is causing it and its impact.
Your GP, specialist or Parkinson’s nurse will be able to discuss options that might work for you.
Fatigue can be made worse by doing too little or trying to do too much. Spreading out or ‘pacing’ your physical and mental activity is an important way to manage the problem.
People who try to cram everything into a short period of time while they have the energy, tend to ‘crash’ afterwards, making their fatigue worse. Other people avoid activity to stop themselves becoming fatigued. However, this also seems to make fatigue worse over time.
Anything that you can do to manage your stress levels is likely to have a positive effect on your fatigue. Practically this means that there are a number of things you can do yourself to try to avoid fatigue or help minimise it.
If you are working, it may not be easy to rearrange your daily tasks. Instead, try to take regular, short breaks. This can help your concentration and avoid fatigue building up.
A break can be something as simple as making a cup of tea, having a chat with a colleague, or sitting back for a few moments with your eyes closed.

AROUND THE HOME
If you live with someone, it may be useful to divide household tasks, so that you do the jobs you can manage more easily.
There are also a number of gadgets and home adaptations that can help you make your daily life with Parkinson’s easier. An occupational therapist can provide expert advice on this.

Exercise is good for people with Parkinson’s, especially if you experience fatigue.
Fatigue can often trigger a cycle in which you become less and less active. This can happen if your daily activities make you feel tired. But the less you do the weaker your muscles become and the more fatigued you’ll feel.
Exercise can help you manage your fatigue, boost your mood and help you sleep well. The more you can do the more benefits you’ll get. So find something that suits you at the right level and go for it. This could be as simple as chair-based exercise or a brisk walk that gets your heart rate up.
To get started, a physiotherapist can recommend exercise that is right for you. Also, exercise referral schemes may be organised in your local area through your GP, local council or sports centre.
Find out more about the benefits of exercise and the different types to focus on.
Fatigue is not just physical. Mental exercise is also important so try to stay involved with any hobbies and interests. If you have time during the day, try to do a variety of activities, as boredom can also lead to fatigue.
Eating a healthy, balanced diet is important, so try to make sure you are eating a variety of foods.
Some people find that a small snack every couple of hours provides them with a constant supply of glucose, which is used for energy and can help reduce the feeling of tiredness in the short term.
It is also important to try not to become constipated (when stools are hard and difficult to pass), as this can make you feel sluggish. Ask your GP or Parkinson’s nurse if you need help managing constipation.
Sometimes, you may feel fatigued after a large midday meal. A short nap may be particularly helpful at this time and may reduce the sense of fatigue. You could also try having a smaller, lighter meal at lunchtimes.
It’s important to do what you can, but try to pace yourself – don’t ignore feelings of fatigue.
Try to perform as much of your daily routine as you can by yourself, but take a rest or get help when you think you need it. If you are feeling fatigued, it may help to spread what you do over the course of your day rather than forcing too much into a short amount of time.
You may find that even after a good night’s rest you are feeling more fatigued than usual. This may be due to having overworked the day before or it may simply be due to the way your condition fluctuates. Whatever the cause, keep in mind that you will have days when you feel more energetic than others.
Remember, your fatigue won’t go away immediately or completely, but with time and consideration, you should be able to recognise what you can do and when you may have difficulty.
You can then plan your time so that episodes of fatigue are minimised or managed. If you are on medication you can also plan around the times when it is most effective. Achieving a good balance between rest and activity will help you handle fatigue and improve your general quality of life.
Measuring fatigue accurately can be difficult as it is unique to each individual, so assessing your own fatigue and what works for you can be a good place to start. We have a non-motor symptoms questionnaire available to help you and your healthcare professional assess symptoms such as fatigue.
You could also try keeping a diary to monitor your fatigue and work out how to manage it. This may help you to arrange to do more difficult daily tasks when you are less tired.
SLEEP AND NIGHT-TIME PROBLEMS
Many people with Parkinson’s can experience problems with sleep. You may wake up during the night because of tremor or stiffness, when you are having difficulty turning over in bed or if you need to go to the toilet.
This can often leave you feeling tired and lethargic during the day and may mean you are not able to complete tasks so well. Poor sleep does not cause fatigue but may make it worse.
Night-time problems will also make you sleepy during the day and resting may help. However, frequent napping can make sleeping at night more difficult.
It is important that you find the reasons for sleep and night-time problems because many of them can be treated and that may help you feel better during the day.
Understanding the causes can also help you to develop good sleeping habits that give you more energy overall.
Many people with Parkinson’s experience depression, even if they are not formally diagnosed with it.
Depression involves more than just feeling ‘down’ for a short while. A person who is depressed can experience a range of symptoms, as well as low mood, for long periods of time.
It is common for people with depression to experience fatigue and depression may make fatigue worse. However, not everyone with fatigue feels depressed.
If you are diagnosed with depression, there are effective treatments available. They may involve a combination of medication, talking therapies or counselling.
If you have fatigue and are concerned about depression, speak to your GP, specialist or Parkinson’s nurse.
Apathy is described as a lack of enthusiasm and emotion for everyday activities. This can feel like depression and fatigue. You may find you lose interest in activities that you previously enjoyed.
Apathy, like depression, needs to be diagnosed so it can be treated. You may find it helpful to speak to a mental health specialist or counsellor about it.
The Equality Act 2010 (England, Scotland and Wales) states that employers must make reasonable adjustments for people with disabilities. These could include flexible or reduced hours, or allowing for a little extra rest, either at a regular times each day or whenever necessary. There is similar equality legislation in Northern Ireland.
If you are a member of a trade union, they should be able to negotiate on your behalf to ask your employer to make reasonable adjustments. They should also be able to advise on other disability discrimination issues.
If fatigue or any other symptoms of Parkinson's have an impact on your daily life, you may be entitled to some benefits, such as Personal Independence Payment. This can be paid to people who are in work, as well as to people who are not.
