Following encephalitis, people commonly experience fatigue, from a general feeling
of tiredness, a lack of energy, weariness or even lethargy. Although this
is sometimes more apparent, and more readily recognized, in the early stages of
recovery, it can frequently present as a long-term difficulty. Whereas people normally
may tire gradually, a person who has been ill with encephalitis may suddenly reach
a threshold where they are over-tired and unable to continue. This sudden onset
cannot be controlled and the only remedy is rest, although it may be the case that
this break need only be brief, or may be achieved by changing activity.
If you are in recovery from an encephalitic episode it will be important to follow
a structured programme of activity and rest follow a structured programme as follows:
- keep to graded mental activities followed by rest followed by graded physical activities
followed by rest
- The periods of activity should initially be short and the rest long then slowly
reversed
- If any symptoms or problems re-appear (like difficulty with speech/concentration/shortness
of temper, headaches) then the programme should be slowed down or longer rest periods
taken
- putting rest periods into the day can be useful for weeks, months or even years
after illness
- rest is preferably lying down in a quiet dark room - not watching TV and not falling
asleep
- make sure you know where there is somewhere you can go to (either at work or home)
that is reliably quiet and restful
- keep a log of your activities and rest periods so that you can plan effectively,
and get the benefit of seeing change happen over a longer term
- It is crucial that you pace yourself - change does not always happen in a progressive
way, and you need to pace things to your abilities over time - there will be "good
days" which might be followed by "bad days".
Getting better Sleep
Fatigue is often associated with a poor sleep pattern. Especially if the person
has had to be away from home and have had a neurological problem that affected sleep
patterns. The following might be useful to help sleep:
- Have a regular routine. Go to bed and get up at roughly the same time each
day.
- Avoid drinks with caffeine (tea, coffee, coke) after 5pm. Do not drink alcoholic
drinks excessively (remember, alcohol and caffeine disrupt your sleep).
- Do something relaxing before you try to go to sleep e.g. listening to music, relaxation
techniques (remember, watching T.V. or reading can both stimulate your mind
and may cause you to toss and turn).
- If you have things running through your mind, write them down before you go to bed.
- Avoid sleeping during the day if you have to, have very brief naps, but try to have
a plan for reducing how often you have them, and for how long.
- If you are not asleep after 15-30 minutes, get up out of bed and do something relaxing
until you feel sleepy. (Remember: Lying in bed tossing and turning will make you
frustrated and make it even harder to get to sleep.)
- Pacing activities for the day.
Fatigue is considered a condition in its own right when it is not relieved
by adequate rest, adequate sleep, or removal of stressful factors. Individuals who
awaken fatigued and the level of fatigue remains constant throughout the day may
be suffering from depression. Fatigue that is not relieved by normal means, or that
occurs in the absence of a known cause or other symptoms should be fully assessed
by a responsible medical person or team. This is particularly important in the case
of encephalitis as encephalitis can affect parts of the brain that might control
sleep and arousal, as well as memory and thinking, but also involves a host of psychological
stresses. It is vital that the survivor and her/his family be helped to get a picture
of how much of a person’s current fatigue is due to medical and/or psychological
factors so that an appropriate, and realistic, treatment plan can be drawn up.
There are 2 main ways of tackling fatigue problems, general lifestyle changes and
specific treatment plan. There are also ways to improve sleep patterns that
could affect fatigue.
Lifestyle changes:
The following might be useful:
- Taking breaks (holiday/long weekends)
- Keep a balanced diet
- Keep a program of regular exercise (within prescribed limits)
- Maintain adequate relaxation and/or rest periods
- Manage time by re-setting priorities and maintain a reasonable schedule of activities
- Develop good sleep habits (see above)
Bear in mind that taking stimulants does not work and can actually make the problem
worse when the drugs are discontinued. Tranquilizers generally intensify fatigue.
Also, alcohol makes sleep more disturbed.
