The list provided by the accredited colleges has 20 names of Geniuses who were mentally ill and mostly from the west. I tried to think of Indian geniuses who might have been mentally ill but did not come into open due to stigma or just ignorance . I thought about our folk lore and epics and the following names come to my mind. But this is only my surmise and hypothetical .
Among our modern day geniuses there is not much written due to Indian way of keeping anything connected to mental illness secret. Hope the stigma attached to Mental illness goes or the genius himself has got the guts to tell his illness without guilt or fear.
The link to the 20 geniuses is below.
