Mitochondria & Alzheimer’s

Alzheimer’s disease researchers have had to do a complete revision of thinking. For decades, the focus has been on getting rid of an abnormal protein, called amyloid, that plonks itself  in the brains of people with Alzheimer’s.

It was a reasonable hypothesis. Amyloid and Alzheimer’s seem to go together, so it seemed logical that in getting rid of amyloid proteins, Alzheimer’s would be cured.

Billions of dollars later, and despite lots of trials with amyloid-chewing drugs, it seems that amyloid is not the culprit.

Q: So what is the culprit?
A: Lots of things, especially mitochondria, the batteries that power our cells.

It’s not a surprise that miserable mitochondria are heavily involved in Alzheimer’s. More and more evidence is showing that moping mitochondria appear in many different diseases. It seems that cell battery management is critical, which makes a lot of sense.

The number of articles linking Alzheimer’s and mitochondria are increasing, and the hope is to find pharmaceutical solutions. That’s good, but there is a solution already in place. And one without side effects.

Photobiomodulation acts on the cell mitochondria, the cell batteries, and boosts the cell activity, stimulates the cell nucleus to start making new cells, opens up the blood vessels and stimulates the blood vessels to sprout more branches. We know from research, case studies and observations of people with Alzheimer’s disease that red and near infrared transcranial lights used daily can improve memory, judgement, attention and concentration, mood, apathy, sleep quality, fatigue, not to mention increasing enjoyment of life.

It would be so good if some of those billions of dollars for Alzheimer’s research would include more work on photobiomodulation.
