Tired, exhausted, or a question of MS and fatigue

I am still tired, still overtired, as I slowly recover from a bout of fatigue. Regular readers may have noticed that my posts have been a little sporadic lately. Fatigue has been the reason.

Of course, it is more than tiredness, more than exhaustion. It is debilitating. So, what is it?

Personal experience tells me that fatigue in MS is not just an ordinary tiredness. Forget about the sort of tiredness you might receive after a day of hard work. like you might get at the end of a hard day’s work. I agree with people who describe it as an overwhelming sense of tiredness with no obvious cause.

According to the MS Society:

  • You may feel extremely tired after very little activity
  • You may wake up feeling as tired as you did when you went to sleep
  • Your limbs might feel heavy, and it becomes harder to grasp things or to write
  • Other symptoms, like difficulties with balance, vision or concentration, might also get worse temporarily

Just like MS itself, fatigue affects people in different ways.

When I looked into the issue, I found that there are two different forms associated with MS. These are Primary fatigue, caused by nerve damage, and secondary, caused by factors relating to MS.

Primary fatigue is thought to be a direct result of damage to the central nervous system, such as demyelination or inflammation.

Fatigue: No single brain area identified

The MS Society says:

Some studies suggest that certain parts of the brain are linked to MS fatigue. But no single area of the brain has been identified. Fatigue might be due to damage in several areas of the brain or spinal cord.

Some researchers suggest that fatigue might be caused by the way that the brain adapts to the impact of MS.

MRI scans of people who have fatigue show that they use larger areas of the brain to carry out activities than people without fatigue. Perhaps the brain is finding new routes for messages when the usual nerve paths have been affected.

early treatmentCauses of secondary fatigue include MS symptoms such as: muscle weakness, stiffness, pain, tremor, depression, mobility difficulties, and lack of sleep – or disturbed sleep resulting from things like bladder problems or muscle spasms-

Additionally, heat sensitivity, infections, and medications can all make fatigue worse for people with MS.

The society does have a word of warning, however. It says:

Many common drugs used to manage MS and related symptoms have side effects that add to fatigue. If you start a new medication, change doses or change the time you take the drug, your fatigue levels might also change. Discuss any changes with the prescribing doctor – don’t adjust your drugs without advice.

One thought on “Tired, exhausted, or a question of MS and fatigue

  1. My personal experience w/ MS fatigue has been interesting. I found that I need to take a rest every 4-6 hours. I need to go to sleep. The thing is…It only has to be long enough to “go out”. Like when a computer reboots, it may only be one minute actually asleep. That’s all it takes and I am refreshed. Longer increments of sleep make no difference. I come home from work on my lunch hour each day. The nap is more important than the nosh.
