I think I am suffering from fatigue.
Fatigue in Parkinson’s is an acknowledged “non-motor” symptom (that is, it is not a visible sign of motor impairment such as tremor or slowness). However, it is not necessarily as well understood as some non-motor symptoms, not least because it has an assortment of possible causes.
Fatigue is a common symptom of depression, and depression is a common symptom of Parkinson’s. But that doesn’t mean that fatigue in Parkinson’s is due to depression and in my case, I’m pretty certain that it isn’t. I don’t feel depressed.
Just as depression is more than feeling down in the dumps, more than a temporary period of pessimism, fatigue is more than just being tired or sleepy. It’s difficult to describe either difference (as I perceive them) except to say that there is a different quality, an intensity of experience in both cases. I have only skirted the edge of depression once, and that was some yeas ago, but I got close enough to recognise it as something other. What I feel now is not that, but it has the same desperate overwhelming type of effect and it is purely to do with feeling tired, sleepy or weary.
I think that at least part of the cause, for me, is my recent change of medication. My consultant suggested to me that ropinirole can instil a form of hyperactivity (which I think may have buoyed me through previous shortages of sleep) and that coming off ropinirole (as I just have done) can result in a period of sleep problems and consequent tiredness.
Sleep at night is a problem, although it’s not as bad as it has been. I go to sleep reasonably well, and at a reasonable hour, but I often wake at 4 in the morning. Most nights (usually after visiting the bathroom) I can get back to sleep for a couple of hours. I’m not often overly troubled by Parkinsonian tremors or rigidity at these times, which seems to indicate that I’ve more or less got the levels of controlled release Sinemet right.
And my difficulties sleeping don’t just affect me. My husband is a light sleeper and I have inadvertently woken him or disturbed his sleep on countless occasions.
General weariness combined with sudden, intense increases of tiredness during the day are a big problem. These are the main reasons I think that I am fatigued rather than tired-because-I-didn’t-sleep-well.
Curiously, I can sleep for up to two hours if I allow myself to when I feel this intense tiredness. I can also ignore it and eventually it dulls, or push through it by doing something physical, but neither of those are easy. I can’t nap unless I’m in that period of intense tiredness (I’ve never been able to nap in the past), and it’s not every day that it’s convenient or possible to nap when my body tells me it needs to sleep. It’s a bit difficult to collect children from school at 3:20 if you let yourself go to sleep in the early afternoon.
I don’t feel right napping in the day. I do feel better after a two hour nap, but not for long, and I’m concerned that it might be adversely affecting my sleep that night.
So I had a bit of a hunt around on the Internet to see what I might be able to do. Advice from Parkinson’s UK and the Michael J Fox Foundation (two organisations that I trust) points very strongly in one direction:
I need to exercise more.
