Indeed, Greeley seemed to be a classic, if unusually tragic, case of what doctors of the day referred to as neurasthenia—a sort of catchall diagnosis encompassing anxiety, depression, insomnia, loss of appetite, physical exhaustion and other symptoms typically attributed to overwork. Greg Daugherty, Smithsonian Magazine, 19 Sep. 2024 But neurasthenia alone wouldn’t account for Greeley’s death. Greg Daugherty, Smithsonian Magazine, 19 Sep. 2024

Word History

Etymology

neur- + asthenia, probably after Italian neurastenia

Note: Italian neurastenia (now nevrastenia) appears to have been introduced, in reference to what was taken to be a form of tetanus (tetano nervoso or tetano astenico "nervous" or "asthenic tetanus"), by the Pavia physician Giuseppe Bergamaschi in "Osservazioni medico-pratiche sul tetano," Giornale di medicina pratica, edited by Valeriano Luigi Brera, fascicolo 29 (settembre-ottobre 1816). Bergamaschi's neurastenia is cited as "neurostenia" in John Mason Good's The Study of Medicine, 2nd edition, vol. 4 (London, 1825), p. 353. The word was reintroduced to refer to a psychological disorder by both the American psychiatrist E.H. Van Deusen ("Observations on a form of nervous prostration, (neurasthenia,) culminating in insanity," American Journal of Insanity, April, 1869, vol. 45, pp. 445-61) and the American neurologist George Miller Beard ("Neurasthenia, or nervous exhaustion," Boston Medical and Surgical Journal, new series vol. 3, no. 13, April 29, 1869, pp. 217-21).
