65
Q

Some serious causes of secondary headache?

A

• Related to increased intracranial pressure
o Mass lesion – tumor, vascular malformation
o Intrinsic increase in intracranial pressure – pseudotumor cerebri
• Other causes
o Subarachnoid hemorrhage
o AVM, aneurysm
o Meningeal irritation
o Stroke
o Hypertensive encephalopathy

66
Q

how to know if headache is related to increase in ICP?

A

• Severe occipital headache
o Sneezing, coughing, any Valsalva maneuver, or change in head position exacerbates the pain
o Pain is worse in the morning or awakens the patient from sleep
o Projectile vomiting without nausea and focal seizures may occur

67
Q

Pain is worse in the morning or awakens the patient from sleep. What is the mechanism of this?

A

Pag tulog ka bumabagal yung respiratory rate mo, mas relax ka. Pag naghahypoventilate ka tumataas yung carbon dioxide. If there is accumulation of carbon dioxide, your blood vessels dilate. Vasodilatation leads to cerebral perfusion and you further increase the intracranial pressure. Kaya ang isang gamot (or solusyon) sa high ICP ay hyperventilation to drive off the carbon dioxide para hindi masyadong mataas yung (volume ng) blood coming to the brain just enough for cerebral perfusion

68
Q

Red flag in patients with migraine

A

o Systemic signs/ symptoms/ disease/ fever, Myalgias, weight loss, history of malignancy or AIDS
o Neurologic signs or symptoms (altered mentation, seizure, papilledema, focal neurologic findings)
o Onset sudden /thunderclap headache
o Older age/ new onset of headache after age 50
o Pattern change from previous headaches (especially if rapidly progressive in severity and frequency)

69
Q

Indications for neuroimaging in a child with headache?

A
  • Trigeminal autonomic cephalalgia including cluster headaches in child or adolescent
  • An acute secondary headache (i.e., headache with known underlying illness or insult)
  • Headache in children <6 yr old or any child that cannot adequately describe their headache
  • Brief cough headache in a child or adolescent • Headache worst on first awakening or that awakens the child from sleep
