One wavelength Eliza photo

This is an early model of a one-wavelength Eliza. You can see that it refuses to lose its inner bucketness.

The elastic strap helps hold the Eliza on the head, with the back tilted back onto the base of the skull and the front just above eyebrow levels. It doesn’t matter if the red light gets into the eyes. I find it more comfortable to be able read or watch television while wearing an Eliza.

Despite its less than-magnificent-appearance, it gives a good spread of light around the head, and the foil insert reflects the lights a little. It all helps.

The instructions have been posted on the blog. Check out the DIY page on the main menu.

Parkinson’s symptoms & Lights

Over the last two years we have made, for people with Parkinson’s, a number of Eliza light hats, both one and two wavelength. I’ve been musing on what they and we have been noticing. Bear in mind that each person is different, experiencing symptoms in different ways.

We have seen improvements in everyone who uses the lights daily.

The person least likely to notice any improvements is the person with Parkinson’s

Parkinson’s – where is the problem?

The symptoms of Parkinson's Disease appear when the dopamine levels in the brain decline. Dopamine is produced in the brain in the Substantia Nigra, which is located deep in the brain, and is one of the parts of a bigger area called the "basal ganglia".

In Parkinson's, the cells of the Substantia Nigra lose power and their dopamine production slowly declines.

The images below show where the Substantia Nigra is located. The images are taken from different angles and collectively show just how deep inside the brain this area is.

Look for the light blue blob.

Have bucket, will travel…

While writing out the instructions to make light hats from buckets, I’ve been musing on the lives of the 2-wavelength light hats we have made since 2016.

What have the light hats been doing since we gave them away?

Quite a lot, it seems.

  • One went to Europe at the beginning of 2017, and floated down the Rhine, sampling the local beer.
  • Three went wandering in outback Australia. One came home but two are still out there, somewhere in the wilds of Western Australia.
  • One did a presentation to a Parkinson’s Support Group in February 2017. The participants were not impressed by the bucket’s attire but they were impressed by what its two wavelengths had been doing.
  • One is based in regional NSW but travels all over Australia, packed in a carry-on bag with socks and jocks stuffed inside the bucket next to the switch box.
  • The others are quietly working at home. They might be planning grand adventures – who knows.

 

The ideal bucket for your Eliza

  • Plastic – not too thin as these can split when you cut them.
  • Internal diameter at the top around 260mm (~10.5 inches). Definitely no less than 240mm (~9.5 inches) and no more than 300mm (~12inches).
    Bucket diameter
  • Straight sides. Well, straight-ish sidesBucket straight sides
  • Depth of around 190mm (~7.5 inches). If you can find one of that depth, then you are saved a lot of cutting and fiddling. If you can only find buckets that are much deeper than that, like the one in the pic above, then brace yourself for some cutting and fiddling.
  • Colour of your choice. If it is close to Christmas, red could be nice.
