1/ 🎥🧵 How do we test someone for #delirium in #COVID19 or any ICU? When someone won’t engage it can be a huge red-flag for “quiet” delirium, which predicts 3X ⬆️ #DEATH by 6 mo & acquired #dementia. Watch this movie of me testing pt #1 for delirium.
2/ What does this mean? He starts out OK but then can’t follow my command to squeeze only on the letter A. Instead, he squeezes when I say the word “squeeze” & doesn’t relax his grip or vary it on different letters. This is inattention & a cardinal feature of #Delirium.
3/ 🎥 Contrast Pt 1 with this Pt 2 video of me doing the same test. This person had delirium on earlier days & is now improving. He gets 8/10 correct responses, which means he’s attentive and not delirious any more. This day he walked & talked for the 1st time!
4/ Here’s a CIBS team member testing another pt (pic w perm). Delirium is not about hallucinations & delusions. Inability to pay attention is the cardinal feature. Pt #1 couldn’t follow my simple command because he was secretly septic & inattention was his 🧠 burglar alarm!
5/ For this test, we recite a letter string (eg, CASABLANCA) & ask the pt to squeeze only on “A” & not on other letters. 8 of 10 correct responses is “attention.” We validated the CAM-ICU in JAMA 2001. It’s now translated in >35 languages & used 🌎 over.

Drowsiness…we just published a meta-analysis of 21 studies (N>50,000 pts) showing reduced arousal had a 6X ⬆️ hospital death rate. This can be the canary in the coal mine for #delirium, which we miss to our pts’ peril 😖!
It may seem hard to believe that such a simple test can predict such important clinical outcomes($ cost, LOS, death, dementia), yet it’s been shown consistently over & over in trials. For non-ICU pts, the 4AT by @A_MacLullich a fabulous bedside clinical tool for #Delirium.

🔸Let’s Unpack @NEJM
🔸Hear from patients
🔸We call LC a disease state
🔸It’s a clinical definition
🔸Adding Inclusion/Exclusion Criteria to our @theNASEM definition fosters great research definitions
🔸 I admit my early mistake…
“Long Covid is an IACC occurring after SARS-CoV-2 infection & present >=3 months as a continuous, relapsing and remitting, or progressive disease state that affects one or more organ systems.”
Read caveats in text box…
3/ Patients describing Long COVID – read text box
“My long Covid life remains terrifying. Last weekend I washed my car, dried it, put it back in the garage. Then I got violently sick and could hardly get up to get food. I was unable to read or even call my mom. I’m a shell of myself. But my physical issues aren’t half as bad as my brain problems. It’s hard to describe. You can say brain fog, but that doesn’t come close to doing it justice.”
“At work my brain is just begging for rest. I struggle with finding words and completing tasks in a timely manner. … I’ll be in a meeting and know exactly what I want to say before I say it. …I’ll get to a word, and I just cannot think of the word. I’ll just be like, ‘Give me a moment,’ and I’ll go through my brain cycling through words. This week the word was “consistent.” I couldn’t think of the word consistent. I kept thinking it was coincident or concentric or constant. I used to build prototypes multiple days a week, and now if I do anything in the lab, I’m pretty much wiped out for a week. …I mean, I’ve had to dig real deep. How much longer will I feel like this? I’m scared.”
2/ Tryptophan is an essential amino acid - we don’t make it.
So if we’re “programmed” to absorb ⬇️ from our diet, we sleep poorly, think worse, and all sorts of other bodily functions go awry.
Will SSRI & SNRI meds help, or anti-virals, or immuno-modulators?
Trials will tell.

This study by @maayanLevy_lab is a marvel of dozens of avenues of science that all point to a greater understanding of the realities of #LongCOVID as a chronic disease state.
Through work like this, we legitimize not only LC, but also #MECFS #LongLyme etc & take one step closer to finding medical solutions for past & future post-infectious states + syndromes like #PICS
1/🧵Catatonia - shocking & hopeful insights into a mysterious neurological disorder 💥
Did Oliver Sacks’s Catatonic “Awakening” Patients have a treatable Autoimmune Disease?
Here I unpack story & science from a stunningly well-done @WashingtonPost article
2/ Amazing Discoveries of Autoimmune Disease causing Decades of Catatonia, Schizophrenia
Autoantibodies and treatment with immunosuppressive medications are waking some patients up with crazy cool results. Here’s the article and my highlighted excerpts:
3/ “The first conclusive evidence was in her bloodwork: It showed that her immune system was producing copious amounts and types of antibodies that were attacking her body. Brain scans showed evidence that these antibodies were damaging her brain’s temporal lobes, brain areas that are implicated in schizophrenia and psychosis.”
📌 I didn’t think #MECFS was real till #LongCOVID opened my eyes
📌 It’s “mysterious” & we weren’t taught it in med school
📌 Yet 1,000s are suffering a disease traditional medicine doesn’t understand
📌 Let’s find answers
2/ Long COVID is estimated at 6% of US Population… @CDCgov
“Prevalence of #longCOVID among U.S. adults ≥18 ⬇️ from 7.5% during June 2022 to 6.0% during June 2023.”
More than 1 in 4 w LC have activity limitations, ie, it’s a LIFE altering disability.
📌A picture is emerging
📌It’s not pretty
📌Most pts w months-long symptoms aren’t recovered @ 2-yrs
📌The cluster including neurocognitive & cardiovasc symptoms is ominous
📌These data fuel trial design
2/ This Lancet investigation of just over 500 patients is not particularly large but is well done. The methodology used LC patients from Catalonia Spain from 3/2020 to 2/2022.
They included people who were unable to obtain Covid test but who had an acute onset of symptoms extremely consistent with the syndrome and who developed the same long-term definition of long Covid.
Some may argue about this point but the longCovid community has taught me how important these patients are to include in such research.
3/ Looking at this figure you can see the heat map emphasizing symptoms in clusters B & C that the authors are most confident indicate persistence.
📌Include ~340k COVID patients vs ~7M controls out to 2 yrs
📌Organ dysfunction persists in 33%
📌Levels of disability from #LongCOVID exceed those of cancer & heart disease‼️

2/ Remember that these data complement the 8 or so other studies showing similar findings, and EXTEND the information using VERY large control groups w censoring if those controls got COVID.
✏️Thus, older and more white than the average #LongCOVID person
✏️They also do NOT help us with Delta and Omicron variant COVID
✏️These findings are robust and statistically sound and published by very astute and qualified investigators
✏️But they must be extended scientifically in cohorts that include a high number of younger women, people of color and lower SEC as well as newer COVID variants.
