I had noticed when thunderstorm are in the area or striking,Having the feeling of a off time or just not feeling well,I had post this on similar site like this for question and answer for parkinsons.I thought i would get negative responces from people,But I really do feel sick with thunderstroms and lighting storms,A neuro doctor who monitor the site and assist with the question and answers,Said that I wasn't far off with my question.With the electric fields in lighting storms throwing out electric charges to effect the neurons in the brain and with parkinsons there is alot of misfiring of neurons,Hey with a DBS it works with a electrical stimulations.Well any way,They said I wasn't far off,the barometric pressure can affect the neurons in the brain as per this neuro doctor and other people felt the same affect,I don;t know if this a issue for anyone,But I do feel a change in my parkinsons during a lighting storm
