Neurasthenia

Neurasthenia is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Neurasthenia rather than just read about it. In short: Neurasthenia (from Ancient Greek νεῦρον (neuron) 'nerve' and ἀσθενής (asthenés) 'weak') is a term that was first used as early as 1829 for a mechanical weakness of the nerves. It became a major diagnosis in North America during the late nineteenth and early twentieth centuries after neurologist George Miller Beard reintroduced the concept in 1869.

Key takeaways

  • Neurasthenia belongs to biology; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Neurasthenia to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Neurasthenia from memory before moving on to harder problems.

Reference excerpt

Neurasthenia (from Ancient Greek νεῦρον (neuron) 'nerve' and ἀσθενής (asthenés) 'weak') is a term that was first used as early as 1829 for a mechanical weakness of the nerves. It became a major diagnosis in North America during the late nineteenth and early twentieth centuries after neurologist George Miller Beard reintroduced the concept in 1869. As a psychopathological term, the first to publish on neurasthenia was Michigan alienist E. H. Van Deusen of the Kalamazoo asylum in 1869. Also in 1868, New York neurologist George Beard used the term in an article published in the Boston Medical and Surgical Journal to denote a condition with symptoms of fatigue, anxiety, headache, heart palpitations, high blood pressure, neuralgia, and depressed mood. Van Deusen associated the condition with farm wives made sick by isolation and a lack of engaging activity; Beard connected the condition to busy society women and overworked businessmen. Neurasthenia was a diagnosis in the World Health Organization's ICD-10, but deprecated, and thus no more diagnosable, in ICD-11. It also is no longer included as a diagnosis in the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders. The condition is, however, described in the Chinese Society of Psychiatry's Chinese Classification of Mental Disorders. Americans were said to be particularly prone to neurasthenia, which resulted in the nickname "Americanitis" (popularized by William James). Another (albeit rarely used) term for neurasthenia is nervosism.

Symptoms

The condition was explained as being a result of exhaustion of the central nervous system's energy reserves, which Beard attributed to modern civilization. Physicians in the Beard school of thought associated neurasthenia with the stresses of urbanization and with stress suffered as a result of the increasingly competitive business environment. Typically, it was associated with upper class people and with professionals working in sedentary occupations, but could still apply to anybody working within a monetary system. Freud included a variety of physical symptoms into this category, including fatigue, dyspepsia with flatulence, and indications of intra-cranial pressure and spinal irritation. In common with some other people of the time, he believed this condition to be due to "non-completed coitus" or the non-completion of the higher cultural correlate thereof, or to "infrequency of emissions" or the infrequent practice of the higher cultural correlate thereof. Later, Freud formulated that in cases of coitus interruptus as well as in cases of masturbation, there was "an insufficient libidinal discharge" that had a poisoning effect on the organism, in other words, neurasthenia was the result of (auto‑)intoxication. Eventually he separated it from anxiety neurosis, though he believed that a combination of the two conditions existed in many cases. In 19th-century Britain and, by extension, across the British Empire, neurasthenia was also used to describe mental exhaustion or fatigue in “brain workers” or in the context of “overstudy”. This use was often synonymous with the term “brain fag”.

Diagnosis From 1869, neurasthenia became a "popular" diagnosis, expanding to include such symptoms as weakness, dizziness and fainting. A common treatment promoted by neurologist S. Weir Mitchell was the rest cure, especially for women. Data from this period gleaned from the Annual Reports of Queen Square Hospital, London, indicates that the diagnosis was balanced between the sexes and had a presence within Europe. Virginia Woolf was known to have been forced to have rest cures, which she describes in her book On Being Ill. Charlotte Perkins Gilman's protagonist in The Yellow Wallpaper also suffers under the auspices of rest cure doctors, much as Gilman herself did. Marcel Proust was said to have neurasthenia. To capitalize on this epidemic, the Rexall drug company introduced a medication called "Americanitis Elixir" which claimed to be a soother for any bouts related to neurasthenia.

Treatment Beard, with his partner A.D. Rockwell, advocated first electrotherapy and then increasingly experimental treatments for people with neurasthenia, a position that was controversial. An 1868 review posited that Beard's and Rockwell's knowledge of the scientific method was suspect and did not believe their claims to be warranted. William James was diagnosed with neurasthenia, which he nicknamed "Americanitis", and was quoted as saying, "I take it that no man is educated who has never dallied with the thought of suicide." In 1895, Sigmund Freud reviewed electrotherapy and declared it a "pretense treatment". He emphasized the example of Elizabeth von R's note that "the stronger these were the more they seemed to push her own pains into the background." Nevertheless, neurasthenia was a common diagnosis during World War I for "shell shock", but its use declined a decade later. Soldiers who deserted their post could be executed even if they had a medical excuse, but officers who had neurasthenia were not executed.

Worked examples

Example 1 — a first encounter with Neurasthenia

Start with the simplest possible case. Write down what Neurasthenia claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Neurasthenia before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Neurasthenia ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Neurasthenia

In research
Neurasthenia appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Neurasthenia in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Neurasthenia is common in secondary-school and first-year university syllabi. It links to neighbouring topics Anxiety disorders, Military psychiatry, Neurological disorders, so understanding it makes those chapters shorter.
In everyday life
Look for Neurasthenia outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Why does Neurasthenia matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Neurasthenia?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
