O'Malley Family

I am researching my mother's family who were originally from Killasser Co Mayo and were moved to Westmeath by the government as far as I know.  I have obtained the Death Certificate of Edward O'Malley (her brother) who died in Mullingar Mental Hospital on 27th November 1954 aged 32.  Can anyone help me in obtaining his medical notes from the hospital as I am keen to learn his definiative diagnosis.  Is St Loman's the only psychiatric hospital in Mullingar?
