4. HISTORY OF NEURASTHENIA
• Neurasthenia (from the Ancient Greek νεῦρὀν neuron
„nerve“ and ὰσθενὴς asthenès “weak”) is a term that was
first used at least as early as 1829 for a mechanical
weakness of the nerves and 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.
• Americans were said to be particularly prone to
neurasthenia, which resulted in the nickname

that manifests itself as an unexplained exhaustion that occurs after
physical or mental exertion. Its name comes from the words "neuro"
(which refers to the nervous system and particularly the mind) and
"asthenia" (which is a feeling of weakness or physical exhaustion).
• Phases of neurasthenia
• 1) The hypersthenic phase: This phase is characterized by symptoms
such as fatigue, sleep disturbance, irritability and state of excitement.
• 2) Irritable weakness phase: In this phase a feeling of impotence is
generated which generates weakness and irritability that may be
accompanied by spontaneous crying.
• 3) Hyposthenic phase: This final stage of the disease, takes time to
appear and is characterized by feelings of lethargy, apathy, passivity
and lack of interest with the desire to cry.

this process.

and rest schedules, goes outdoors and is temporarily isolated from the work
and educational environment.

14. UPDATE RELATED TO
NEURASTHENIA
The Somatoform disorders, Neurasthenia and Fatigue syndrome are being
replaced for ICD-11
with a single "Bodily distress disorder (BDD)" category which is close to the
DSM-5 "Somatic
symptom disorder (SSD)." BDD poses the same threat to CFS and ME
patients as DSM-5's SSD.
