One I know, had yesterday been in contact with the French researcher behind the rTMS trail at the right angular gyrus. The trail should according to the design from 2015 be a placebo controlled with a 100.patients. Last year they hoped to be finish around sept 2020 but they are still open for patients living in France.
This is really depressing that a trail can take more than 6.years because they can not locate a 100.patients in the Paris area. Research into depersonalization was until recently done at two small units in London and New York that made some small examinations like brain scans and small trail,- clearly underfunded if one looks at the sizes of the patients used. Now, these are closed.
So, the only research there is are some small studies done in other european countries. This is not enough if there shall be some hope of a treatment.
The unawareness and that it is still highly undiagnosed seems to be the core problem in getting founding, recutting patients for doing more research into this condition. Deeply concerning.
