My husband has been using the helmet and PD care laser by Symbyx.
He started end of February. I see some improvement but hopeful for more positive results. His brain fog seems to be slowly disappearing.
No regrets on buying the equipment and would do it again.

Yes! I have the Symbyx PD Care and Neuro transcranial helmet. So far, I love them. I'm only on week 6, and they say to look for improvements around 10-15 weeks. Regardless, I love having something I can do and honestly I like the feeling I get when I'm doing it. Have you tried it yet?

I haven't heard of it I'll check it out
