I’m regularly asked if it is possible to track any changes when starting to wear a light hat.Continue reading “Keeping records”
When I went to medical school, the belief was that you got your full quota of brain cells at birth. It was downhill from there, and you entered old age with not many brain cells left.
What a joy it is to know that this belief is a load of rubbish.
Here is a great article, summarising recent research on the birth of new brain cells during our lives.
It is a reminder that you use your brain or you lose it, so lifelong learning stimulates the birth of new brain cells.
I can recommend learning a musical instrument – you can do it at any age. Making music on your own instrument really makes your brain work, whether you are a beginner or an old hand at it.
Prof John Mitrofanis gave an excellent presentation today to clinicians at the Royal Hobart Hospital.
He took the audience through the ten plus years of research into red lights and Parkinson’s in animal models.Continue reading “Red lights preserve brain cells…and make more of ‘em”
I’ve been reading articles suggesting that Alzheimer’s disease is linked with a disruption of brain wave patterns, especially the gamma waves which are predominant in the brain when we are concentrating and focussed.
One group increased gamma wave activity in Alzheimer’s mice by pulsing light. In this research, it wasn’t the light that was of interest to the researchers, it was the pulse rate. They used 40Hz, in the gamma brainwave frequency range.
Here is a great report about that experiment and it’s implications.
…stimulating neurons to produce gamma waves at a frequency of 40 Hz reduces the occurrence and severity of several Alzheimer’s-associated symptoms in a mouse model of the disease.
It seems that pulsing the light does more than enable red light to penetrate more deeply into the brain. Pulsing at 40Hz seems to stimulate the brain’s immune and clean-up cells, the microglia to get cracking with brush and pan.
I have visions of microglial cells dancing to the 40 Hz rhythm as they clear up brain rubbish, including the proteins that accumulate in Alzheimer’s – amyloid and tau.
In 40Hz pulsed red light, the brain gets the benefits of the red light action inside the cells, and the benefits of brain-protection activities stimulated by brainwaves responding at 40Hz.
Fascinating stuff, isn’t it.
Meanwhile, if you are feeling worried that your Eliza or Cossack doesn’t pulse, don’t fret. The daily light dose is doing its work. More.
Philip Ball’s article in The Guardian is terrific.
It explains many complex aspects very clearly, especially amyloid and tau proteins and the history of different approaches to drug development.
Read to the end, where he mentions the possible link between Alzheimer’s and the bacteria that cause gum disease.
Seems like we should embrace teeth-cleaning with far more enthusiasm and hope.
It won’t hurt.
The ABC story showed photos of Ron Brown and me.
On the right hand side of the picture, you can see an Eliza bucket light hat, like the one Max Burr now uses.
In the middle you can see what look like coronets. Which is what we call the light device we have designed. It doesn’t have jewels on the outside, but it has fabulous pulsing individual LED lights, all controlled by sophisticated firmware.
Ron is an electronics engineer and he the genius behind this astonishing design.
- It is very lightweight – around 125g.
- It can be quickly set up to fit different head shapes, large and small.
- Each of the eight legs has two rows of individual LED lights, one is 670nm and the other 810nm.
- The Coronet has special firmware that allows us to modify key parameters:
power – pulse rate – timing – location of the light on the head
- It also comes with an app for android phones only (sorry, iOS users), which allows the user to pause and resume a session – see how long here is to go before the session finishes – see the technical details of what the device is doing while you wear it – monitor your own progress using a tremor-test and reaction test.
For Parkinson’s disease, we ensure the settings we think will work the best, based on what the research is currently indicating, for example:
- pulsed light is far more effective than continuous red light.
- 670nm followed immediately by 810nm works better than either alone or both together
We might be biased, but we believe the Coronet to be the most sophisticated light device available now for people with PD to try.
We have nearly sold out our first batch but will be ordering more.
