Patients with Myalgic Encephalomyelitis have a variety of specific care needs, some of which are well-known and common to a variety of other illnesses and others which are unique to M.E. and with which hospital staff or carers may be wholly unfamiliar.
Inappropriate care (even if well intentioned) can have serious consequences for M.E. patients in the short term and the long term, or even permanently. Knowledge of some of the basics about how M.E. affects the body is vital if you are in the position of providing care for someone with M.E. in order to avoid additional unnecessary suffering and disability. This paper provides a brief overview of this topic for hospital staff and carers.
What is Myalgic Encephalomyelitis? How does it affect the body?
Myalgic Encephalomyelitis is a debilitating neurological (CNS) disease which has been recognised by the World Health Organisation since 1969 as a distinct organic neurological disorder with the code G.93.3. It can occur in both epidemic and sporadic forms and over 60 outbreaks of M.E. have been recorded worldwide since 1934.
M.E. is an acute onset neurological disease initiated by a virus (an enterovirus) with multi system involvement which is characterised by post encephalitic damage to the brain stem (hence the name ‘Myalgic Encephalomyelitis’). M.E. is similar in a number of significant ways to diseases such as multiple sclerosis, Lupus and Polio. At least 25% of M.E. sufferers are severely affected and are almost completely (or completely) housebound and/or bedbound. Children as young as five can get M.E., as well as adults of all ages. M.E. has a similar strike-rate to multiple sclerosis and is a (potentially fatal) chronic/lifelong illness.
M.E. is primarily neurological, but because the brain controls all vital bodily functions virtually every bodily system can be affected by M.E. Although M.E. is primarily neurological it is also known that the vascular and cardiac dysfunctions seen in M.E. are also the cause of many of the symptoms and much of the disability associated with M.E. – and that the well-documented mitochondrial abnormalities present in M.E. significantly contribute to both of these pathologies. There is also multi-system involvement of cardiac and skeletal muscle, liver, lymphoid and endocrine organs in M.E. Some individuals also have damage to skeletal and heart muscle.
Thus Myalgic Encephalomyelitis symptoms are manifested by virtually all bodily systems including: cognitive, cardiac, cardiovascular, immunological, endocrinological, respiratory, hormonal, gastrointestinal and musculo-skeletal dysfunctions and damage. Myalgic Encephalomyelitis affects the brain, the heart, almost every bodily system and every cell of the body. One of the defining features of M.E. is an inability to maintain homeostasis.
What all of this means in practice is that patients with M.E. have to be very careful with or limit:
- Physical activity
- Cognitive activity
- Sensory input (exposure to light, noise, movement and vibration), and
- Orthostatic stress (maintaining an upright posture)
The main characteristics of the pattern of symptom exacerbations, relapses and disease progression (and so on) in M.E. include:
- People with M.E. are unable to maintain their pre-illness activity levels. This is an acute (sudden) change. M.E. patients can only achieve 50%, or less, of their pre-illness activity levels post-M.E.
- People with M.E. are limited in how physically active they can be but they are also limited in similar way with; cognitive exertion, sensory input and orthostatic stress.
- When a person with M.E. is active beyond their individual (physical, cognitive, sensory or orthostatic) limits this causes a worsening of various neurological, cognitive, cardiac, cardiovascular, immunological, endocrinological, respiratory, hormonal, muscular, gastrointestinal and other symptoms.
- The level of physical activity, cognitive exertion, sensory input or orthostatic stress needed to cause a significant or severe worsening of symptoms varies from patient to patient, but is often trivial compared to a patient’s pre-illness tolerances and abilities.
- The severity of M.E. waxes and wanes throughout the hour/day/week and month.
- The worsening of the illness caused by overexertion often does not peak until 24 - 48 hours (or more) later.
- The effects of overexertion can accumulate over longer periods of time and lead to disease progression, or death.
- The activity limits of M.E. are not short term, a gradual (or sudden) increase in activity levels beyond a patient’s individual limits can only cause relapse, disease progression or death in patients with M.E.
- The symptoms of M.E. do not resolve with rest. The symptoms and disability of M.E. are not just caused by overexertion, there is also a base level of illness which can be quite severe even at rest.
- Repeated overexertion can harm your chances for future improvement in M.E. M.E. patients who are able to avoid overexertion have repeatedly been shown to have the most positive long-term prognosis.
- Not every M.E. sufferer has ‘safe’ activity limits within which they will not exacerbate their illness, this is not the case for the very severely affected.
In short, if patients with M.E. exceed their individual post-illness physical, cognitive, orthostatic and other limits, they will experience some combination of the following:
- A mild-severe (acute or delayed) worsening of one or more symptoms for hours, days or longer afterward
- A mild-severe (acute or delayed) worsening of virtually every symptom for hours, days or longer afterward
- A severe (acute or delayed) worsening of the base level of illness/disability for hours/ weeks/ months or even years afterward, or
- A permanent worsening of the base level of illness/disability (i.e. permanent physical damage is caused and chances for significant recovery are adversely affected or taken entirely)
It is also important to be aware that repeated or severe overexertion can also result in the death of the M.E. patient. (Death in M.E. is most often caused by heart failure or multiple organ failure.)
So what are the top 10 most obvious things you need to be aware of in providing care to a M.E. patient?
- Reduce exposure to light
- Reduce exposure to noise
- Reduce/eliminate all non-essential visitors
- Do not encourage patients to be more physically active (or upright longer) than they can easily tolerate
- Try to schedule demanding tasks for the patient's best time of day as much as is possible
- Try to reduce the patient’s levels of cognitive exertion and sensory input
- Be aware of any special dietary requirements
- Be aware of the likelihood of negative drug reactions
- Be aware of the need for extensive rest and problems with sleep
- Be aware that these aforementioned relapses can be delayed, and that they can be very serious and prolonged
1. Reduce exposure to light
-Some patients will require the room to be completely dark (or very close to it), some will be fine so long as blinds and doors are kept closed, while other patients will fit somewhere in-between these two extremes.
2. Reduce exposure to noise
-At a minimum, doors and windows must be kept closed to reduce noise. Anyone entering the room must also take care to reduce or eliminate noise as much as possible, particularly if a patient has severe noise sensitivity.
-Open wards such as in emergency rooms are a DISASTER for M.E. patients. They WILL without exception cause months or more of severe relapse in the severely affected and may also cause a more immediate worsening of the overall condition and should be avoided if at all possible. (Moderately affected patients may also relapse severely in an open ward.) Sharing a room with another patient is also inappropriate for the severely affected M.E. patient and will also cause a high level of increased pain and suffering and long term relapse.
-The problem here is not merely pain in the ears and painful or burning eyes. Even low levels of noise or light (and other sensory input) can cause a significant and prolonged worsening of the severity of the condition overall, as well as symptoms including seizures, severe mental confusion and inability to process even very simple information, episodes of paralysis, problems with proprioception, balance and so on. Pain levels can quickly soar to a 10/10 level even with moderate or brief noise or light exposure, and recovery can be prolonged.
3. Reduce/eliminate all non-essential visitors
-As well as reacting badly to the extra noise and light exposure caused by visitors, patients can also be made sicker by watching the movement of someone in the room, and by the extra demands made on the brain when talking and listening to speech is required.
-In the case of cleaners, these should be cancelled for the duration of the hospital stay, both for the reasons outlines above, and because many M.E. patients have sensitivities to many common chemicals used in cleaning products. (Exposure to these chemicals may merely trigger headaches but in some cases they can cause extremely severe relapse.)
-It is counter-productive and ill-advised to do hourly ‘obs’ (pulse and blood pressure checks etc.) on a patient with severe M.E. as this will soon cause them to deteriorate in both the short and the long term (or even permanently).
4. Do not encourage patients to be more physically active (or upright longer) than their bodies and hearts can easily tolerate
-Even sitting up in bed propped up by a few pillows counts as ‘being upright’ when someone is severely affected, and even 30 seconds or a few minutes of being fully upright may be long enough to cause problems.
-Physical activity doesn’t just include strenuous activity, but any movement. Even simple movements or stretching of the muscles can cause a worsening of the condition in the severely affected. Physical tasks may need to be broken up into many smaller tasks with long rest periods in-between.
5. Try to schedule demanding tasks for the patients best time of day as much as is possible
-Find out when the patient’s best time of day is, and try to fit tasks in to that window as much as possible.
-Don’t expect that a patient will necessarily be able to do the same things at different times of the day. Some tasks may only be possible at certain times of day, or after a long period of rest. Making a patient do difficult tasks at the time of day when they are at their most ill, can not only make the task much harder or impossible, but also cause a far worse relapse than if attempted at their most well time of day.
6. Try to reduce the patient’s levels of cognitive exertion and sensory input
-Sensory input includes; light, noise, movement, touch and also vibration. (The vibration felt when by travelling by car can be excruciating. Even being lifted from one bed to another can be unbearable.)
-Cognitive exertion includes talking and listening to speech, reading and writing, watching TV, listening to music and so on. Talking as well as listening to speech can be very difficult or impossible. Cognitive tasks may need to be simplified and broken up into many smaller tasks with long rest periods in-between.
-Some severely affected patients are unable to maintain consciousness for more than short periods at a time. Some may only be properly conscious for a few hours a day or less. Sometimes consciousness cannot be maintained for more than 10 minutes or so consecutively (or less). Trying to force these patients into consciousness for longer periods can only be counter-productive, unfortunately. It can quickly make the problem even worse. (Aside from certain medications and other treatments, what will help improve this condition most is rest.)
-Some patients will require wheelchairs, but those who also have severe orthostatic problems (problems with being upright, including sitting) must not be put in wheelchairs at all and will need to be moved lying flat in bed (or lying flat on the back seat of a car) at all times.
7. Be aware of any special dietary requirements
-Patients will often be intolerant of a large variety of foods. Some may also have food allergies.
-There may also be strict requirements – due to the metabolic problems seen in M.E. – that a patient eat every 2 or 3 hours (or even more often) and that meals or snacks be high in protein and low in sugar and carbohydrate to prevent relapse. (High sugar or high carbohydrate foods are often very poorly tolerated by M.E. patients).
-Some patients will require assistance from a carer to eat (or tube feeding in severe cases). Problems with swallowing can also make eating or drinking difficult or impossible for the M.E. patient.
8. Be aware of the likelihood of negative drug reactions
-M.E. patients can react badly to almost every type of drug; particularly those which act upon the CNS. Some severely affected patients are unable to tolerate any drugs or over the counter vitamins and other supplements at all, although many will have found a small number of products that they can tolerate through much trial and error.
-Negative effects from taking certain medications can range from headaches and feelings of being poisoned, to a severe worsening of the overall condition, and so on. The relapse caused by medications can also sometimes be semi-permanent; the patient does not regain the level of health they had before they tried the new medication.
-All new medications should be started one at a time and at very low doses (eg. 1/10th of a standard dose)
- If a M.E. patient is in hospital for surgery, please be aware that certain precautions must be taken with anaesthesia for the safety and wellbeing of the patient. Please read: Anaesthesia and M.E.
-Patients may also react badly to the chemicals contained in many personal care products. If this sensitivity is very severe, visitors must avoid wearing these products as much as possible before visiting.
9. Be aware of the need for extensive rest and problems with sleep
-Patients with M.E. need a lot of rest, but often find it impossible to get much sleep or find initiating sleep very difficult, or can only achieve a very low quality of sleep or sleep only for short periods at a time.
-It may take some patients 4 or more hours to initiate sleep. Being interrupted with noise or light or visitors during this time may make that period even longer, or prevent the initiation of sleep altogether. Even low level noise can sometimes wake M.E. patients who cannot achieve normal deep sleep and so are very light sleepers.
-Some patients cannot ever sleep for more than a few hours a time post-M.E., and so they need to be left alone as much as possible in order that they get these much needed sleep periods. (Sleep doesn’t necessarily help M.E. symptoms much – often patients feel just as ill or even much worse on waking than they did before they went to sleep – but missed sleep causes severe worsening of symptoms/disability. The way it feels to have M.E. and not to have slept much the night before is indescribably horrific, particularly when M.E. is severe.)
10. Be aware that these aforementioned relapses can be significantly delayed (and so they are not always visible on superficial examination), and that they can be very serious and prolonged - or even fatal in a minority of cases
-Don’t make superficial (i.e. wrong!) judgements of a patient’s ability levels. If you want to know how a patient is feeling or if they can or can’t do a certain task, just ASK THEM!
- People with M.E. are very highly motivated to be as active as they possibly can be (as anyone would be with so many restriction on their lives), but they know that if they push themselves to do more than their bodies can handle, the end result will be a huge LOSS of ability levels, and a higher level of suffering, and so this is not in their best interests. (The way people with M.E. get to be as active as possible is by carefully staying within their post-M.E. limits. This also gives the patient the best chance for their best possible long-term prognosis.)
-Do take the risk of relapse, and the patient’s unwillingness to unnecessarily become far more ill for days, weeks or longer – very seriously. Many M.E. patients are suffering in a fairly extreme way already, and their lives are so painful and limited as to almost be unbearable already, without any additional worsening of the condition.
In conclusion
Just do your honest best. Achieving all of these tasks perfectly all the time may not be possible, it’s a lot to take in and a lot to think about all at once, but everything that you can do to reduce the relapse from a hospital stay will make a real difference and be much appreciated. There is a huge difference between a 2 month long relapse and a 6 month relapse and between symptoms worsening during this time to a 7/10 level rather than a 9/10 or 10/10 level... or between a relapse that merely lasts weeks or months, or is semi-permanent or permanent.
(We appreciate what a hassle it is to accommodate the demands of M.E. only too well. M.E. is an acute onset disease. We went from being normal and healthy one day to having to cope with all these limits and disabilities the next. Or from one hour to the next even. We get it that M.E. is very unforgiving, overwhelming and just a huge hassle to deal with on just about every level. We think so too. But this doesn’t change the reality, unfortunately.)
Following this text are some additional forms about specific symptoms and disabilities etc. that patients may or not want to (or be well enough to) fill out in order to give you more information about their needs, where this is appropriate. Thank you for taking the time to read this paper.
Additional notes on this text:
- For more information on all aspects of M.E. see: What is Myalgic Encephalomyelitis?
- If a M.E. patient is in hospital for surgery, please be aware that certain precautions must be taken with anaesthesia for the safety and wellbeing of the patient. Please read: Anaesthesia and M.E.
- Note that hospital trips (or any travelling out of the house) should be an absolute last resort for patients with severe M.E. because of the enormous price they pay for such trips. It should be avoided wherever possible. Requiring patients with severe M.E. to go to hospital (etc.) is like making a person with two freshly broken legs walk for 5 hours to get medical help. It’s as counter-productive and cruel as it is agonisingly painful.
This extreme level of suffering is not short term either. It is very, very common for severely affected patients to spend 6 months, 12 months, several years or longer recovering from a hospital trip, or for the patient to still not have regained their previous low-level of health 5 or more YEARS later. Some never do recover. (Again, there have also been cases where a M.E. patient has left hospital only to go home and die.)
People with severe M.E. are some of the most vulnerable members of society and they deserve and desperately need appropriate care; care given in the home as much as possible. It is unreasonable that these already very severely ill patients have to be made so much more severely ill to get the basic care they need, most of which could easily be administered at home at an immensely reduced physical cost to the patient.
- What is Homeostasis? Homeostasis is the property of a living organism, to regulate its internal environment to maintain a stable, constant condition, by means of multiple dynamic equilibrium adjustments, controlled by interrelated regulation mechanisms. Homeostasis is one of the fundamental characteristics of living things. It is the maintenance of the internal environment within tolerable limits. M.E. causes a loss of the ability of the CNS (the brain) to adequately receive, interpret, store and recover information which enables it to control vital body functions. There is a loss of normal internal homeostasis; the individual can no longer function systemically within normal limits.
Metabolic problems at a cellular level also contribute to this inability to maintain homeostasis in M.E. M.E. expert Dr Byron Hyde explains that: ‘In MRI spectography of arm muscle of M.E. patients, it has been shown that because of an abnormal build-up of normal metabolites, the muscle cell actually shuts down to prevent cell death.’ This is what is happening to the M.E. patient’s cell physiology in every muscle (including the heart) and in the brain as a result of physical and cognitive activity and/or overexertion (etc.); there is ‘cell field shutdown’ to prevent the death of the cell. See: Treating Myalgic Encephalomyelitis - Avoiding Overexertion for more information and for references.
- What does ‘rest’ mean exactly?
Resting means completely different things at different severity levels. For the mildly ill being at rest may mean watching TV or perhaps sitting in a chair reading a book or having a quiet night in with friends. For the severely ill, these things are not at all restful and indeed would provoke severe relapses.
For the very severely ill, resting means lying down in a dark room, in silence and with no inputs at all (such as TV or radio or light) and not moving at all physically or engaging in any type of cognitive activity. Clothing must also be comfortable and the room must be neither too warm or too cold. For the very severely ill a better term would be complete incapacitation, rather than 'resting.' The term resting also implies that the inactivity is optional and this is often not the case in the severely ill who are often 'resting' (incapacitated) because it is physically impossible for them to do anything else.
For moderately ill patients resting means something somewhere between the two extremes, and so on.
Of course for the very severely ill there will be no safe or symptom-free activity limit and concepts of pacing or of stopping activities when symptoms appear are useless unfortunately and indeed a sizeable proportion of the very severely ill may well be so severely affected in the first place BECAUSE of overexertion in the early stages of their illness - because they were not told how important it was to rest or were not allowed to rest adequately. This is very common in M.E. unfortunately.
- Try not to make superficial judgements of ability or severity!
You can probably observe people with some illnesses carefully for an hour or so and collect a lot of good information about what they can and can’t do, how severe their illness is, and what their usual symptoms are from day to day, and so on. But M.E. is not one of those illnesses. Observing your average M.E. sufferer for an hour – or even a week or more – will not give an accurate indication of their usual daily activity level because the severity of M.E. waxes and wanes throughout the hour/day/week and month and people with M.E. can sometimes operate significantly above their usual illness level for short periods of time thanks to surges of adrenaline – albeit at the cost of severe and prolonged worsening of the illness afterward. Relapses of symptoms are very often also significantly delayed.
Just observing someone with M.E. do a certain task should not be taken to mean; (a) that they can necessarily repeat the task anytime soon, (b) that they would have been able to do it at any other time of day, (c) that they can do the same task every hour, day or even every week, or month, or (d) that they wont be made very ill afterwards for a considerable period because they had to really push themselves (and make themselves ill) to do the task. Often a considerable rest period is needed before and after tasks, this may involve hours, weeks or months. (Someone may need 2 weeks rest before an outing for example, and may then spend 3 weeks extremely ill afterwards recovering from it; so just looking at them in the 2 hours they were ‘out and about and mobile’ is of course not at all representative of their usual ability levels.)
Most importantly, because the worsening of the illness caused by overexertion very often does not even begin until 48 or more hour afterwards (when most observers are long gone) you also can’t tell by looking if a particular activity was so far beyond a M.E. patient’s individual limits that they will end up having made themselves severely or even permanently more ill by completing the task. (Or even if it killed them, to be blunt. It isn’t common, the M.E. death rate is estimated at 3%, but deaths can and do occur.)
