In my job as a pediatric neurologist, we consult with pregnant people if a brain abnormality was found on ultrasounds. We provide information on prognosis. If the prognosis is bad or high risk, elective pregnancy termination should be an option. (1/9)
We also prescribe anti seizure meds to people with epilepsy, who need to take these meds for months, often years. Some of these meds have potential to cause serious birth defects, or have unknown safety during pregnancy. (2/9)
Same goes for migraine meds, immunologic meds (treatment for multiple sclerosis, etc). Even if neurologists and insurance companies require a contract or proof of contraception, birth control isn’t 100% effective. (3/9)

1) Have you ever seen a case of rabies?

I saw two cases 5 years back and they have stayed with me since.

I do not fear any disease per se but I am not ashamed to say that I dread rabies --> it is a terrible affliction.
2) The first patient was a small child of around 7 years old --> he had been bitten by a street dog around 1 month back. But his family had opted for natural healers.

When he was brought in, he was crying uncontrollably with a terror stricken expression on his face.
3) Hydrophobia, as commonly believed, is not so common in these cases. Why you ask?

Its because these patients are so extremely agitated and combative, its very difficult to get close to them, let alone make them drink water.

1) Bell's palsy (BP) is typically defined as an IDIOPATHIC unilateral LMN type CN7 palsy.

It is named after the Scottish neurophysiologist, Charles Bell. (vide infra)
2) But an LMN type CN 7 palsy is NOT the same as Bell's palsy.

It is merely the idiopathic form, often thought to be due to herpes or varicella induced direct nerve damage or as post infectious demyelination.
3) There are certain RED FLAGS in the diagnosis of an LMN type CN 7 palsy.

1. Vesicles on the tympanic membrane or ear canal (Ramsay Hunt syndrome type 2)

2. Bilateral involvement - Lyme disease, sarcoid, GBS, Melkersson-Rosenthal syndrome, Mobius syndrome etc!

One of my favorite #histmed stories is the discovery of EEG by Hans Berger in the 1920s. #NeuroTwitter

At age 19, Berger (1873-1940) fell off a horse. On the same day, his sister, miles away, sent a telegraph to ask if he was doing ok. 1/10
He was fine, but he thought he had communicated his frightened thoughts about getting hurt to his sister by telepathy. He decided to study psychiatry, to learn more about inter-brain communication. 2/10
Berger wanted to measure the "psychic energy" that, he thought, tied us all together. He wrote about the "radioactivity of the brain," he studied circulation, he measured temperature of the brain during mental exertion (in a 23 yo patient with a gunshot wound to the head) 3/10

What previous paper, you say? In case you missed it, please check out why evaluating reliability for RCT outcome measures is as important as for diagnostic tests, if not more:
lnkd.in/g4piwx6T

As everyone knows, mRS is widely used for evaluating functional outcome in stroke pts.

A simplified version (smRS) was proposed by Bruno et al. for easier adjudication.

While reliability was extensively studied for stroke pts, it wasn't for patients with treated aneurysms.

🚨Acute #stroke case (from the archive):

Patient in 60s presents with sudden onset fluctuating LOC, dysarthria, mild right arm weakness (disabling)

Last seen normal 2hrs (witnessed onset).

You urgently take to CT- motion artifact, no clear early ischemic changes. CTA normal. Image
2 schools of thought/approaches:

Approach #1⃣: Acute onset, disabling symptoms- proceed with lytic 💉and defer CTP

Approach #2⃣: Dx is still a bit unclear (ddx: seizure⚡️, etc)- proceed to CTP

If in camp #2, here are the CTP maps (CBF, MTT, Tmax>8s) Image
CTP confirms suspected localization of left thalamus (with possible internal capsule involvement).

CTP helped confirm the etiology (not a mimic), but delayed lytic administration by about 7-10 min (did not change management).

Which camp/approach are you in for this case🧠?

The only good thing to come of finding this on my leg last week: I learned enough to write a #tweetorial about it

A 🧵/twitter PSA about what to do if a tick comes for you – & what neuro presentations you can see w/ tick-borne illnesses

#MedTwitter #NeuroTwitter #IDTwitter
2/
After time outside in a non-wooded area, I found this on my leg. I didn’t realize what it was, so I grabbed it & flung it off... only to then find a very active, crawling tick on my counter. 😱

So after freaking out for a moment (or 2), I had to figure out what to do with it.
3/
Memories from med school flashed into my head of what you’re SUPPOSED to do:

1⃣ Remove tick w/ tweezers
2⃣ Grab close to skin & pull tick off without twisting so it doesn’t break apart
3⃣ Disinfect

Since I had already accidentally messed up 1⃣ & 2⃣, I started w/ 3⃣

Everyone loves those pretty colored fMRI pictures with the blobs. But what do they mean? How do they make them?
A #tweetorial called “F— that: Understanding fMRI”. #FOAMed #medtwitter #Medstudenttwitter #neurotwitter #FOAMrad #neuroradiology #radiology
2/
fMRI is based on a principle called “neurovascular coupling.” This is the principle if there is increased neuronal activity in a region, there will be increased blood flow to that region to meet the increased demand
3/
Think of it like a baby crying because it is hungry—parents immediately rush to feed it. The increased oxygen demand of the neurons immediately brings increased fuel to feed it.

“You don’t get points for having your needle in the right place if you don’t get a diagnosis.” When we biopsy the skullbase we work to get a diagnosis.
A sort of #tweetorial but more like a 🧵about our skullbase biopsy system. #FOAMed #medtwitter #neurosurgery #neurotwitter Image
2/
Unless the lesion is difficult to diagnosis w/FNA (ie, schwannoma), we begin by FNA w/an 18g draw needle & a 22g Quincke needle. We do not aspirate, b/c the skullbase is very vascular, & too much blood will be drawn up, making it difficult to tell if the sample is diagnostic. Image
3/
However, if we are not getting a diagnosis with FNA, we will move to a core. If it is a deep lesion, we will use the Biopince system, beginning with a 17g, 7 cm introducer. This is an example of IgG4 disease of the trigeminal nerve that failed FNA and required a core Image

re: ICH Prevention in People w ⬆️Risk MRI findings in @American_Heart updated 2022 ICH guidelines🧠🩸

📌 Refers to incidentally found MRI markers of small vessel disease (SVD) - a common question

Prompted by @interneurona unpacking below (short 🪀)
For context:
🚫MRI is not routinely done for risk stratification of first-ever spontaneous ICH risk

🔮MRI is occasionally available in certain people/pts w/o ICH: may show SVD markers concerning for future ICH risk

〽️These markers are: microbleeds, superficial siderosis

1/
The populations that this might be relevant to are:
- healthy elderly
- ischemic stroke
- memory clinic
- any pt who got a brain MRI for a different indication (e.g. migraines)
- non-ICH cerebral amyloid angiopathy (CAA)

Why is cranial nerve 6 uniquely affected by⬆️ intracranial pressure? Why is it special? A common question after the CN6 tweetorial.
Here is a maybe #tweetorial, but maybe a🧵about why CN6 is alone affected by ⬆️ pressure. #FOAMed #medtwitter #Medstudenttwitter #neurotwitter Image
2/
Think of the intracranial CSF space like a balloon, distended by CSF instead of air. Cranial nerves begin inside the balloon, and then they exit as they begin their extradural portion Image
3/
Most cranial nerves move immediately away from the CSF space after they exit—usually going out through their respective foramina. However, CN6 uniquely runs along the outside of the “balloon” in Dorello canal Image

🦪 IDK about you but I did NOT learn about "vision tilting" as part of lateral medullary syndrome. I had a stroke code this AM where patient woke up to find the room appeared to be flipped "like a mirror image, upside down". #MedTwitter #neurotwitter
Involvement of the vestibular nuclei in lateral medullary lesions can result in nystagmus and diplopia (which we are taught), but can also result in vertical image displacement, referred to as 'environmental tilt'!!
This is due to injury to do the otolithic projections that typically help our vision to mediate "counter rolling"

A conversation I have every week in @yaleneurons resident clinic: let's talk triptans. A basic approach for all you #neurotwitter and #medtwitter folks who aren't board certified in headache medicine 🤯but see these patients- just like me!
This topic is dear to my heart b/c I have migraines and let me tell you- migraines. are. awful. My life was changed when I got triptans. Gimme some suma + high dose NSAIDs = 😃 But not all triptans are created equal! If your patient fails one, it doesn't mean you're out of luck.
Let's say you start with sumatriptan 50mg PO (my usual starting choice) and the patient has side effects. What should you do?

Hi #MedTwitter #MedStudentTwitter #neurotwitter #MedEd #FOAMed! It's been too long since my last #EndNeurophobia #tweetorial so here's an introduction to brain imaging–thanks @sarrovasta for the request!🧠❤️
cc:@CPSolvers @rabihmgeha @DxRxEdu @AvrahamCooperMD @caseyalbin
1/🧵
Let's start w/CT. I'll focus on brain (and not bone or soft tissue). First:

* Identify normal structures and any abnormalities in:
- Size
- Shape
- Symmetry
(note *symmetric* abnormalities such as ventriculomegaly or diffuse cerebral edema may not be obvious w/o experience)

2/
Next:

* Identify abnormalities
- Hypodensity
- Hyperdensity

Broadly:

• Hypodensity:
- Ischemia
- Inflammation
- Infection
- Neoplasm

• Hyperdensity:
- Blood
- Calcification
- Hyperdense tumors (e.g. lymphoma)
- Thrombus in vessel
- Contrast enhancement
