Over the course of my life to this point I have been one of those people who happily talks to himself. Sometimes it’s just the odd word, other times entire sentences, paragraphs or scenarios. At school, in one of those boarding schools of random brutal discipline, I talked to myself and was roundly and openly vilified for the practice. “Stamford” I heard a prefect bellow across New Court “why are you talking to yourself? Are you going mad?” It reminds me, some 50 years later of that famous drill instructor in Full Metal Jacket.
I often talk to myself and find it no cause for concern. If it is an indicator that I’m becoming insane, it’s taking its time about it. I am no more mad than I have ever been for the last 50 years. Now when people ask me why I talk to myself I say “it’s the only way that I can be sure to enjoy intelligent conversation.”
However, brushing aside such jocularity for a moment, let me introduce a slightly darker dimension to such conversations. I mean of course The Big H. Hallucinations. From the marginal to the major, these are all a part of “The Parkinson’s Experience” as the great Phineas T Barnum might have styled matters. Partly the underlying pathology of Parkinson’s itself and partly the superimposition thereupon of complex psychotropic drugs, hallucinations represents that ragged edge between normality and delirium.
For me, hallucinations have been a predictable if, for the beginning at least, neutral companion, neither reassuring nor Intimidating. The usual stuff – crawling insects typically around the periphery of vision, disappearing upon any visual saccade.
Small animals too are not uncommon subjects of hallucinations, sometimes no more than a sense of presence rather than explicit visual sighting. What kind of animals? Mice, shrews and voles mainly. Certainly nothing much bigger. No need to worry about rats the size of cats.
As the condition progresses, the hallucinations becomes more complex and concrete. Visual persistence changes as well as does their perception as real, competing with real real, if you get my drift. Only last week, I was chased around the kitchen table by a guinea pig the size of a cougar. Fortunately, being of a reasonably widely read disposition, I realised instantly that this was not a guinea pig but a capybara. Of course that’s only part of the answer. I still haven’t established why a capybara was in my kitchen. This is where REM sleep kicks in, making the unbelievable believable. Once you have established that the house guinea pig is now the house capybara, anything is possible.
A good friend of mine was particularly troubled by hallucinations – not by the hallucinations themselves (for in truth he had none at that stage) but the idea of them, the notion that these alternative realities might one day show up to play games with his cognition.
Over the years, not surprisingly, the frequency, intensity, and credibility of my hallucinations has extended substantially. The flies and cockroaches are largely unseen, kept at bay by the mice, all the way up to the capybara. An entire food chain in action.
But the animal components of the hallucinatory landscape are infinitely less disquieting than the participation of human hallucinations. For a couple of years now I have been woken in the middle of the night by my children wanting to talk over matters of some urgency. Not in and of itself disturbing except for the fact that my children are all grown up now and dotted round the country. Dotted around other countries even.
How do these figures occur? As ghostly, pale ectoplasmic wraiths, translucent embodiments? No, they appear exactly as they would were they actually present. And do these figures fade away as I turn my gaze to them? No, again they are very real. I have become so accustomed to their presence that the only way I can distinguish them from their genuine embodiments is by trying to shake their hands. My hands pass through theirs.
I can hear you, dear reader, composing the question to me – if my hallucinations are this real, and I safe to drive? Will I find myself swerving into the path of oncoming vehicles or mowing down entire classes of schoolchildren? The answer is of course no, I can’t make those guarantees. And that is why I surrendered my driving licence last year. The toughest decision I have yet to face in the context of Parkinson’s, but a necessary one.
Am I becoming demented? Are these hallucinations the first foothills of dementia’s mighty peak? I don’t know. I have had Parkinson’s for some 18 years. Maybe I have held the line, like Stonewall Jackson’s Virginia infantry in the face of impossible odds. Maybe it can be successfully treated? I don’t have those answers to hand but I do know, if nothing else, it is time to ask the questions.
