Q

Describe the prodromal stage of migraines? What is it mediated through?

A

Yawning, polyuria, neck pain, food cravings, mood changes, mental fogginess, light sensitivity
Mediated through the hypothalamus and connections to other structures such as locus coeruleus and TCC (trigeminocervical complex where TG and cranial structures converge with cervical afferent s from upper cervical spine) which impact sleep and neck pain respectively.

Q

Describe the aura and what it is pathophysiologically

A

Aura is before or during the HA - visual or sensory motor language or brainstem dysfunction.

Related to Cortical spreading Depression (CSD) - spreading depolarization across cortex followed by a relative depression of electro graphic activity

16
Q

International Classification of HA disorders (ICHD -3) has 3 categories of HA:

A

Primary
Secondary
Cranial neuralgias/facial pain

17
Q

Migraine, tension type and trigeminal autonomic cephalgias (cluster) are types of _______ headaches.

A

Primary.

18
Q

_____ % of migraines are withOUT aura.

A

75

19
Q

1st line Tx for migraines

A

Triptans - 5HT-1B and 1D receptor targets (serotonin)

20
Q

What type of pharmacotherapy for migraines is newer and actually have a preventative action on migraines?

A

CGRP receptor agonists - Gepants.

21
Q

How are Ditans different from Triptans if they both treat migraines and target serotonin receptors?

A

Ditans do not vasoconstrict however they may have AEs including dizziness, sedation and and 8hr driving restriction after use. Lasmiditan is a schedule V

22
Q

What is the MOST important aspect to address in patient’s with chronic migraines?

A

Stress reduction. If you can’t get stress under control, then treatments are less likely to be effective.

23
Q

What are some characteristics of a brain tumor headache?

A

30% of patients with brain tumors report HA.

Worse with position change, awakens them from sleep, non-descript (dull, achy). Associated with other neurological abnormalities.

24
Q

What are some nutrition/herbal supplements to help support migraine health?

A

None approved by FDA, but
Mg, vit B2, feverfew have level B evidence in prevention
Coenzyme Q10 has level C evidence.
Melatonin.

25
Q

Lifestyle factors to prevent migraines?

A

Quality sleep, good hydration, healthy diet meals, caffeine and alcohol in moderation, regular exercise and STRESS management.

26
Q

When does Temporal Arteritis typically show up, what are symptoms and what is a serious complication if not treated?

A

Average age onset of 70
Dull aching HA in temporal location.
Blindness if not treated promptly with steroids.

27
Q

How are Tolosa-Hunt syndrome and cluster type headaches similar and different

A

Similar: severe, unilateral periorbital headache
Different: THS - long term and ophthalmoplegia. Inflammation of cavernous sinus with relapsing remitting course and attacks every few months to years.
Cluster type: shorter (1-4hours) with no ophthalmoplegia. Non-inflammatory.

28
Q

Your patient has nausea, vomiting, severe, throbbing headache, photophobia, neck stiffness and fever. What are you suspecting as diagnosis? Why?

A

Meningitis.
Fever. Migraine also has all of the above s/s but no fever.

29
Q

IIH - Idiopathic Intracranial HTN - criteria for Dx?

A

S/s of increased ICP (HA, transient visual obscurations, pulse synchronous tinnitus, papilledema, visual loss)
No other neurological abnormalities or impaired LOC
Elevated ICP with normal CSF composition
Neuroimigaing study shows no etiology for ICH
No other cause of intracranial HTN apparent.

30
Q

Other than HA, what other s/s accompany Cerebral venous sinus thrombosis?

A

Focal neurological deficits, AMS, seizure and papilledema.

31
Q

RCVS is a result of ______

A

Reversible Cerebral Vasoconstriction Syndrome

Diffuse segmental vasoconstriction oof intracranial arteries. Severe and recurrent.

32
Q

Glossopharangeal neuralgia, occipital neuralgia, trigeminal neuralgia are all examples of ______ neuralgias

A

Cranial

33
Q

first line tx for trigeminal neuralgia?

A

Carbamazepine or oxcarbazepine.

34
Q

What is the pathophysiology related to Trigeminal neuralgia

A

Demyelination of the primary sensory trigeminal afferent s in the root entry zone.

35
Q

What are some examples of painful trigeminal neuropathies?

A

Herpes zoster, infection, post-herpetic neuralgia, post traumatic, MS plaque and neoplasm.

36
Q

Trigeminal Autonomic Cephalgias 3 kinds:

A

Cluster HA
Paroxysmal Hemicrania
SUNHA - short lasting Unilateral Neuralgiform headache attack.

37
Q

3 main systems prominent in pathophysiology of Trigeminal Autonomic Cephalgias

A

Pain - starts in V1 branch then projects to the trigeminocervical complex
Cranial Autonomic system - responsible for lacrimation, conjunctival injection and other autonomic features - sphenopalatine ganglion, VIP, target system for oxygen
Hypothalamus - includes circadian system and aggression areas which may explain regularity and restlessness (molecules melatonin, target for verapamil and lithium) .
