This week’s #MigraineChatAMA invited Qs about the relationship between sleep disorders and #migraine.

Nothing shared is medical advice. Please talk to an HCP before making changes to your migraine treatment. Errors are mine. #MigraineChat /1
What is the relationship between sleep and #migraine? “[T]he exact nature and direction of the association remains enigmatic; migraine may be the result of sleep disruption, but also sleep disruption may trigger migraine,... [cont.]
#MigraineChatAMA /2
"...or migraine and sleep disruption may be symptoms of an unrelated medical condition, or they might be two intrinsically related phenomena with shared pathophysiological mechanisms.”
…alofheadacheandpain.biomedcentral.com/articles/10.11… #MigraineChatAMA /3
Regarding common, underlying mechanisms: new evidence suggests that sleep & migraine share important, common brain structures (e.g., the hypothalamus) & common “signaling” neurotransmitters, neuropeptides, and hormones. #MigraineChatAMA /4
What sleep-related conditions are comorbid w/migraine? Insomnia, snoring & sleep apnea, restless leg syndrome, narcolepsy, sleep-wake disorders, parasomnia, sleep walking, teeth grinding, all occur at ⬆️rates in ppl w/#migraine compared to those without. #MigraineChatAMA /5
Source for last few tweets: …adachejournal.onlinelibrary.wiley.com/doi/abs/10.111… [abstract only] #MigraineChatAMA /6
What about nightmares & #migraine? There aren’t a lot of studies on this, but the few exist seem to suggest ppl w/migraine report greater dream “behavior” (evidence of dreaming during REM sleep) & nightmares. mdpi.com/2076-328X/11/9… (see also tweet # 6 source) #MigraineChatAMA /7
We need more research to clarify the relationship: i.e., whether bad dreams are a sort of prodrome (attack is already starting) or bad dreams are related to sleep disruptions and that ends up being the migraine trigger. #MigraineChatAMA /8
Why do we wake up w/a migraine attack? “[I]t’s believed headaches when you wake up are related to changes in the activity of the hypothalamus. This brain region regulates pain perception as well as your natural sleep-wake cycle....” Source ⬇️
#MigraineChatAMA /9
Waking up *in the morning* w/a migraine attack? It could be triggered by a few things:
-Dehydration
-Blood sugar changes
-Alcohol (hangover)
-Medication withdrawal (medication overuse)
-Caffeine withdrawal
-Teeth grinding, clenching
-Sleep pattern* (Cont.)
#MigraineChatAMA /11
Sleep patterns include: too much or too little sleep, inconsistent bedtime or wake times, snoring, sleep apnea, sleep disruptions, insomnia, poor sleep quality. verywellhealth.com/obstructive-sl… #MigraineChatAMA /12
If the attack wakes you in the middle of the night or is worse first thing in the morning (but improves after you wake up), talk to a headache specialist about other headache disorders (three examples follow). #MigraineChatAMA /13
Hypnic headache - key feature is that it only develops during sleep and wakes you up. It also tends to affect both sides of the head and be shorter in duration than a migraine. medicalnewstoday.com/articles/hypni… #MigraineChatAMA /14
Cluster headache - typically severe pain centered around one eye that commonly starts at night, peaks quickly and lasts < 3 hrs. Occurs in clusters and is often accompanied by eyelid droop, tearing, runny or stuffy nose.
ncbi.nlm.nih.gov/pmc/articles/P… #MigraineChatAMA /15
Idiopathic intracranial hypertension - may wake you up or be worse after lying down (improves if upright), can be accompanied by blurred vision, pulsatile tinnitus.
merckmanuals.com/home/brain,-sp… #MigraineChatAMA /16
How to prevent waking up w/a migraine? How to get a good night’s sleep? This depends on the possible trigger(s). I recommend reviewing the list of possible triggers in tweets # 11 & 12, trying to track which might be the likely culprit(s).... #MigraineChatAMA /17
and working w/a headache specialist to determine what treatments or tests are needed: adding a preventive migraine treatment or treating comorbidities (like CPAP for apnea)... (cont) #MigraineChatAMA /18
Non-pharma treatments can include devices (e.g., mouth guards), sleep-focused CBT (CBT-I), changing diet or meal times, practicing good sleep hygiene (when possible). #MigraineChatAMA /19
Many will recommend CBT-I (insomnia), relaxation techniques, or good sleep hygiene. While all these can help, those in the #MigraineChat community often note that sticking to the practices are not always easy when mid-day attacks or fatigue, etc., ramp up. #MigraineChatAMA /21
How to treat a morning migraine? Aside from the above preventive options, consider your acute options. Morning attacks are some of the toughest to tackle because you have lost the chance to “treat early.” #MigraineChatAMA /22
For morning attacks, any of your acute treatments can be used but often non-oral/non-tablet acute treatments will work best for attacks in progress: e.g., IM sumatriptan or ketorolac, intranasal DHE or triptans, orally-disintegrating gepants or triptans, etc. #MigraineChatAMA /23
Why is sleep sometimes restorative, but other times makes migraine attacks worse? This question plagues me, but bear with me as I try to explain in a few tweets.
-We have a glymphatic systems that clears waste, primarily as we sleep. (Cont.) #MigraineChatAMA /24
More...
-Migraine may disrupt the glymphatic system, preventing proper function, possibly creating an accumulation of waste, & contributing to migraine (a vicious cycle).
-Cortical spreading depression in mice was related to impaired glymphatic flow. (Cont.) #MigraineChatAMA /25
More…
-This might be worse in people with chronic migraine due to chronic sleep disruptions.

Friends, I’m going to do an impromptu #MigraineChat office hour to help anyone who wants to get started with - or learn more about - the MigraineChat Discord group. I’ll be online at 1:30p ET.

If you want to join, please DM me and I will share the Google meet link.
I’ve done no planning & will do a more formal tutorial later, so this might be a little chaotic. Right now, Discord is the next most organized place to join #MigraineChat besides Twitter.
New people have joined in the past few days, but I worry the “accept rules to enter” thing is throwing people off. Discord can be overwhelming at first, too.

I want to make it as accessible as possible, but understand it isn’t ever going to be for everyone. #MigraineChat

This week’s #MigraineChatAMA invited Qs abt rebound headache: a topic I wish was more rigorously studied for lots of reasons. The research in this thread is not w/o limitations or issues.

Nothing shared is medical advice. Talk to an HCP before making changes. #MigraineChat /1
Medication overuse headache is the ICHD-3 term. Unofficially, it is often referred to as “rebound” headache. Some organizations are trying to get the name updated to medication adaptation headache (to avoid the stigma of blame). For space, I’ll use rebound. /2 #MigraineChatAMA
How common is rebound headache (HA)? A “true prevalence that is unknown, partly resulting from various changes in diagnostic criteria, but estimates are in the range of 0.5 to 2.6%.” /3 #MigraineChatAMA

This week’s #MigraineChatAMA covered acute CGRPs (gepants). There weren’t a lot of questions, so I threw in a few extra resources. There are Qs for the #MigraineChat community at the end.

Nothing here is medical advice. Talk to your doc before making changes. #MigraineChatAMA /1
Do acute gepants work for those w/chronic migraine (CM)?

Clinical trials typically look at ppl w/episodic migraine first: either excluding ppl w/CM or not enrolling enough to obtain reliable results for the CM subgroup. #MigraineChatAMA
/2
I couldn’t find studies of gepants for acute use in CM. Anecdotally, though, yes! The #MigraineChat community has shared experiences w/Ubrelvy & Nurtec as acute treatments even for those with chronic migraine. #MigraineChatAMA /3

Two weeks ago, I posted the #MigraineChatAMA topic: #CGRP preventives. You had great questions. Some I couldn’t answer satisfactorily, others too big to summarize adequately in a thread (i.e., I’ve give an example study for one CGRP, but other research exists). /1
Quick notes: This is not medical advice, just meant to get you pointed in the direction of things to discuss with your doctor. Also, due to space, terms are defined then abbreviations used. Studies may not use brand names (e.g., erenumab, not Aimovig). #MigraineChatAMA /2
Is it worth ⬆️ Aimovig from 70mg to 140mg if you’ve seen severity ⬇️ but not frequency?

This Q is a little tough to answer because so many of the original studies looked at reduction in monthly migraine days (MMDs) as their main outcome (freq, not severity). #MigraineChatAMA /3

Week 2 #MigraineChatAMA - #migraine types: You had some tough Qs & I don’t have all the answers. Just because I didn’t find them in my search, doesn’t mean they don’t exist. If you have reliable sources of information, please share. Errors are mine. For more info, click links. /1
Types: 2 main types are migraine without aura (MwoA) & migraine with aura (MwA). Under MwA are migraine w/: typical aura*, brainstem aura, hemiplegic & retinal migraine. *Migraine w/typical aura also incls migraine without headache. migraineagain.com/10-types-of-mi…
#MigraineChatAMA /2
Types, cont: menstrual migraine (MM) is a subtype under either MwoA or MwA. If attacks happen only during menses = pure MM. Migraine attacks during menses and other times = mensturally-related migraine.

MM can be tougher to treat.

For this week’s #MigraineChatAMA on Headache Specialists (HAS):

HAS are healthcare providers who completed a year fellowship in headache medicine and become board-certified through an accreditation organization (@UCNSorg). (ucns.org/Online/Online/…). /1
Others might call themselves HAS if they complete add’l qualifications like the @NHF Added Qualification in Headache (headaches.org/aqh/). Other healthcare professionals might regularly attend edu/prof meetings on headache treatment to improve knowledge.
#MigraineChatAMA /2
DYK - HAS are not all neurologists *and* not all neurologists are HAS? A neurologist’s training in headaches or migraine is pretty minimal. Neurology encompasses a broad range of neuro conditions; they may specialize in ones other than headache/migraine. #MigraineChatAMA /3
