Morbid Podcast: Episode Summary

The Sleeping Sickness Epidemic (1919–1930)

Hosts: Ash Kelley & Alaina Urquhart
Date: January 12, 2026

Episode Overview

In this episode, Ash and Alaina take a deep dive into the mysterious and often overlooked Sleeping Sickness epidemic (Encephalitis Lethargica) that swept across the globe in the early 20th century, particularly between 1919 and 1930. Known for its bizarre and terrifying symptoms—including prolonged sleep, catatonia, and mask-like expressions—the disease remains shrouded in mystery to this day, with its cause still unknown. The hosts deliver a mix of detailed medical history, chilling case studies, and their signature blend of comedic banter and empathetic commentary.

Key Discussion Points & Insights

1. Setting the Scene: Post-Holiday Catch-up & Jazz Rituals

• Ash and Alaina chat about social hangovers and finding joy in small routines (03:03–08:57).
• Elaina’s “Gatsby jazz” morning routine: “Get an old timey blue radio looking Bluetooth speaker, then you're really in it. And that shit will change your life…” (06:00)
• Both discuss romanticizing daily life to combat the heaviness of the world.

2. Introducing Encephalitis Lethargica

• The disease isn’t true crime, but checks all the “morbid” boxes—creepy history with an unsolved mystery (09:04).
• Known as sleeping sickness, it caused catatonia, “mask-like expressions of horror,” and hypersomnia (stunningly deep sleep) (09:22).
• Referred to as “the grandmother” or “La Nona,” it was both culturally eerie and medically baffling.

3. Early Outbreaks and Key Figures

• Dr. Constantine von Economo (Vienna) and Dr. René Croissher (Paris) identified and treated early cases, initially mistaking them for battle fatigue, influenza, or PTSD (10:40–13:38).
• Bizarre, varied symptoms included:
  • Hypersomnia (sleeping for days/weeks)
  • Catatonia with mask-like facial expressions
  • Epidemic hiccuping (one death recorded)
  • Verbal tics, twitching, compulsive behaviors (16:18–17:20)
• Only common thread: overwhelming, irresistible need to sleep.

4. Disease Course and Symptoms

• Acute phase: Dramatic symptoms, sometimes progressing rapidly and unpredictably.
• Chronic phase: Sometimes Parkinsonian symptoms, catatonia, or post-encephalitic states lasting for decades (18:38).
• Elena: “It was like the disease was developing new symptoms as it progressed. Yeah, but with no explanation whatsoever.” (17:41)

5. Historical Spread, Diagnostic Mysteries, and Public Response

• Wartime conditions (WWI) acted as a “perfect environment” for spreading unknown illnesses (13:01–14:43).
• Disease spread from Europe to England and the U.S., causing fear—but often overshadowed by the Spanish Flu (26:34–27:45).
• Local authorities, in denial or under-informed, issued misleading public statements:
  • “San Francisco need have no fear of the sleeping sickness… it is well established that the sleeping sickness is carried by the tsetse fly and occasionally by other insects found in Africa…” (40:15–40:45)
  • Alaina: “San Francisco health officials were wrong on literally every point…” (40:56)

6. Memorable & Haunting Case Studies

• Ruth (NY, 1919): 16-year-old girl, acute onset with finger pain, rapid progression to paralysis, catatonic sleep for two months, then death after fever spike (32:52–36:11).
  • “Among the things that puzzled Tilney the most was the fact that although she appeared to be asleep... she was able to respond to simple commands.” (34:32)
• Other presentations:
  • Falling asleep with eyes open and “expressionless faces, free of terror and pain…” (14:04)
  • Delirium, euphoria, patients jumping around at night like toys, patients rambling incoherently or stuck in horror-mask paralyzation. (28:57–30:24)

7. Public Health Reaction and Diagnostic Difficulties

• Denial and confusion from health officials—statements downplaying severity or shifting blame to foreign sources (40:31–44:16).
• Difficulty tracking the true scale, as symptoms overlapped with flu or psychiatric disorders.

8. Theories, Research, and Legacy

• Attempts to link sleeping sickness to influenza or malaria largely debunked by studies (45:54–46:58).
• Encephalitis Lethargica played a significant role in medical discovery:
  • Von Economo hypothesized and identified the hypothalamus’s role in sleep, hunger, temperature—fundamental neurology breakthroughs (24:59–25:00).
• Disease ultimately just faded away without explanation. Occasional, exceedingly rare cases still reported today (47:30–51:00).
• Alaina: “As for the cause of this sleeping sickness, they still don't know to this day…2026, we still have no clue.” (50:45)

9. Aftermath and Modern Insights

• Most survivors profoundly changed—trapped in comas or left with Parkinsonism, tics, or catatonia (48:20–48:44).
• Notable late case: Philip Leather, child prodigy, spent seven decades in a “trance-like state” before dying in 2002. Brain autopsy provided no definitive answers (49:45–50:32).
• Oliver Sacks’s work with L-Dopa in the late 1960s brought some relief to survivors, but with only temporary success.

10. Lingering Questions and Speculation

• Was it viral, autoimmune, environmental, or a combination?
  • Theories include environmental toxins, food or product contamination, or an unusual virus.
• Disease affected all age groups, with no clear pattern.
• Ash: “I feel like we should really continue looking into this, though, so that this doesn't happen again. Let's figure this out. Guys…” (53:03–53:10)

Notable Quotes & Memorable Moments

• Elaina: “Every day is a fucking event. All right? We live in a hellscape… romanticize the little moments.” (07:26)
• Ash: “It kind of sounds like Covid.” (13:39)
• Elaina: “Like, their strange symptoms... they never hit two people the same way.” (13:38)
• Ash, on the epidemic’s disappearance: “Which is so strange… because they didn't know what precautions… so where did it go?” (47:30)
• Alaina: “Cases occasionally pop up from time to time. …But they're super rare. Like exceedingly rare.” (50:43)
• Ash: “If you guys ever want us to cover something… medical things that you would just love to hear a discussion about… throw it our way.” (55:15)
