'baragnosis' originates from Greek, specifically the words 'baros' and 'gnosis', where 'baros' meant 'weight' and 'gnosis' meant 'knowledge' or 'recognition'.

'baragnosis' was formed in modern medical/New Latin usage by combining the Greek roots 'baro-' and 'gnosis' and entered English as a technical neurology term in the late 19th to 20th century.

Initially the roots referred separately to 'weight' and 'knowledge'; as a compound in medical terminology it came to denote the specific condition 'loss of the ability to perceive weight'.
