The perception of time

Friday 19 April 2019

I look around Rosa’s room at the treasures of childhood.

A wooden doll’s house with a roof that opens to reveal little people and miniature furniture. They were once the protagonists in many fairy-tale adventures but now rest in quiet contemplation.

A pencil and charcoal portrait of my daughter sketched by a street artist on Charing Cross Road for ten pounds. Although the picture only has a passing resemblance to her features, it nevertheless captures a moment in time. A content eight-year-old girl on the way home from a West End musical. A proud father looking at the artistic creation unfolding on the easel on a cool April evening.

A metal box overflowing with pens, pencils and artist’s materials of all types. Felt-tips long dried out; broken pastels; assorted paintbrushes encrusted with the remnants of different watercolours; blunt pencils crying out for a sharpener. The box sits on the corner of a wooden desk that is stained with the labours of youthful creativity.

A dusty bookshelf crammed with something for all ages. Beatrix Potter, Roald Dahl and a set of Mr Men books shouldering history textbooks and a large Oxford English dictionary.

Sitting proudly atop the bookshelf is the clock.

A classic child’s alarm clock, with a metal clanger and a face with boldly printed numerals from one to twelve. Pink of course.

I listen keenly to its metronomic ticking.

At first the sound is comforting: constant, trustworthy, reliable, as sure as the moon and the sun. (At least until the battery needs changing.)

But as I continue to listen, the ticking starts to take on a different persona. Relentless, unfeeling, unforgiving. Menacing even. 

I feel my life slipping away with every click of the second hand.

How many neurons did I lose today? How many will die tomorrow? 

I focus my mind on slowing down the clock, willing the second hand to take longer as it stutters around the face. Instead the ticks at first seem to speed up a little before settling back into the same never-ending rhythm.

Einstein’s Theory of Relativity teaches us that there is no fixed time, and that we each follow our own clock which may vary from someone else’s clock according to where we are and how fast we are moving. Precise experiments have confirmed this to be true; an astronaut returns to Earth very slightly younger than his or her family who stayed at home. An atomic clock left on top of a mountain will read slightly differently from one left at sea level when brought back after a few weeks, due to the marginally different strength of the Earth’s gravitational field between the two locations.

Be that as it may, we cannot change the rate at which our individual clocks tick. From our own perspective we still age at the same rate regardless of whether we are living at high altitude or travelling close to the speed of light. The second hand on the watch we wear moves at the same speed, even if it may differ marginally from someone else’s timepiece. So, Relativity, truly remarkable though it is, doesn’t help us master time.

Although the passage of our individual time is unrelentingly constant, our perception of time can and does vary. Rosa’s teenage years will seem to her like an eternity. Those very same years will feel as if they pass much faster for me.

The prevailing theory is that it is the brain’s processing of new information and the creation of new memories – the wiring of new neural connections – that slows down our perception of time; conversely when we are doing nothing new – in effect just using established neural pathways – time feels like it speeds up.

Have you ever had a long weekend where you travelled somewhere new, did lots of memorable things and were stimulated by novel sounds, smells and tastes? Did those three days seem more like three weeks?

And have you ever had a week or a month that was boring and unmemorable. And it seemed to pass by in a flash?

Did you ever walk from A to B in some new place and then find that the walk back from B to A somehow felt much quicker?

I think this theory is right. When the brain is dealing with lots of new information flooding in, it works at the pace of the slowest part of the processing, resulting in the perception that time is running more slowly.

In summary, it’s impossible to halt the march of time, but it is possible to make it seem a little longer by experiencing new things.

And that gives me some comfort. I can never control time itself but I do have some control over my personal experience of time. By doing new things - by stimulating my brain to keep developing - I can not only enjoy life but I can feel as if that enjoyment lasts longer too.

Are these the words of a condemned man clutching at straws? Perhaps. Though I prefer to think of this as doing what I can to take control of my destiny.

I take one last look at Rosa’s room. Indulging in nostalgia is enjoyable and something I will continue to do.

But the clock is still ticking.

It's time to crack on.




The middlegame

Saturday 6 April 2019

Following my last visit to the neurologist, already some two months ago, I am now on a three-times-a-day dose of levodopa (tradename Madopar) in addition to my dopamine agonist (Pramipexole).

A simple thing like upgrading my medication wasn’t straightforward: firstly I had to chase the neurologist for the prescription letter, then my GP surgery cocked up the order to the pharmacy, and then there were the side effects of adjusting to the new drug: daytime sleepiness, irregular heartbeat, nausea, dizziness and so on. In the meantime, my Parkinson’s symptoms were getting worse. How do people less able bodied than me cope, I wonder?

Thankfully, things now seem to have settled down.

To return to my chess metaphor, after some opening sparring where I lost a couple of pieces, I am now embarking on a long middlegame. For now, my defences are stable, but each upgrade in my regimen is akin to a pawn swap with the Parkinson’s Grandmaster: gradually eroding my front line until, eventually, he can exploit my underlying weaknesses. It is a slow process of attrition, and I need to be careful with my moves so as to prolong the middlegame as long as possible.

Indeed, I am now even more reliant on my daily drugs. I read about NMLS – neuroleptic malignant-like syndrome – in the leaflet that comes with my bottle of Madopar. This can occur if I stop taking my medicine suddenly. “NMLS can be life threatening,” it warns. “Signs include increased shaking, high temperature, sweating…” and so the list goes on. A little research reveals that NMLS comes with about a 20% chance of death.

I carry on with my daily life. But it feels like a precarious existence dependent on a global pharmaceutical supply chain. A dependency that will continue for many years until, eventually, I get to the endgame.
