'vasoneurosis' originates from New Latin/modern medical formation, combining the prefix 'vaso-' (from Latin 'vas') and 'neurosis' (from Greek 'neûrosis'), where 'vas' meant 'vessel' and 'neûron' meant 'nerve'.

'vasoneurosis' was formed in modern medical/neo-Latin usage by joining 'vaso-' (a combining form used in terms referring to blood vessels) with 'neurosis' (from Greek via Neo-Latin). The elements come from older words: Latin 'vas' (vessel) and Greek 'neûron' (nerve), and the term entered English medical literature in the 19th–20th century as a descriptive compound.

Initially, it referred specifically to a nervous disorder affecting blood vessels; over time the term has become uncommon or outdated and has often been replaced by more specific diagnoses such as 'vasomotor dysfunction' or 'dysautonomia'.
