Headaches Flashcards
Tension headache summary card
Dull, tight band, gradual/acute, generalised/bilateral, lasts 3-4 hrs, moderate severity, analgesics help, neck/shoulder pain
= most common, everyday headache
= stress, disturbed sleep
= normal O/E
= keep a headache diary, avoid triggers, increase relaxation, simple analgesia (but beware of med-overuse headache)
Cluster headache summary card
Neuro disorder of recurrent, severe, headaches on one side of head w/ cyclical pattern
= intense, sharp, penetrating pain, lasts 15 mins - 3 hrs, severely debilitating, unilateral, behind eye
= watery red eye, facial flushing, nasal congestion
= occurs in men, 20-40 yo, may present as partial Horner’s
Migraine sx and assoc. sx
Unilateral, pulsating/throbbing, paroxysmal/comes on gradually, moderate to severe pain, being in dark room helps
Aura before (flashing lights, tingling), interferes w/ current activities, numbness, tingling, visual changes, photophobia, phonophobia, nausea, vomiting
Migraine triggers
C hocolate H angovers O rgasms C heese/caffeine O CP L ie-ins A lcohol T ravel E xercise
- also bright lights and hormonal changes
Mx of migraines
Conservative
= avoid triggers, keep diary
Acute
= 1) NSAIDs/paracetamol
= 2) triptans
Preventative
= 1) propanolol or topimerate
= 2) amitriptyline
Trigeminal neuralgia summary card
Facial pain syndrome in > 1 division of trigeminal nerve
= unilateral headache around trigeminal division, numbness, stabbing/shooting pain, paraosmal/lasts for seconds
= triggers: eating/chewing, washing face, burshing teeth, shaving face, talking
= assoc. with MS
Meningitis presentation
Acute and severe headache, neck stiffness, photophobia, fever, rash, vomiting, seizures, shock!
Non-blanching petechial rash, Kernig’s sign (hips flexed, pain/resistance on passive knee extension), Bruzinski’s sign (flexion of hips and knees when neck is flexed)
RFs: closed communities/crowding, age < 5 or > 65
Causes of meningitis
Babies = E. Coli, group B strep
Children = H. infulenzae, Strep. pneum.
Young adults = Neisseria meningitidis
Elderly = Strep. pneum., Listeria monocytogenes
Viral = HSV, VZV, HIV, enteroviruses
Meningococcal disease
Rapid onset fever
Non-blanching rash
Malaise
Sx of sepsis +/- meningitis
Ix of meningitis
LP for CSF analysis (contraindicated if increased ICP)
Blood cultures
CT head if neurodeficit/decreased consciousness before LP
CSF analysis for meningitis
Bacterial
= cloudy CSF, increased neutrophils (polymorphic), low glucose, high protein
Viral
= clear CSF, increased lymphocytes (mononuclear), normal glucose, normal/high protein
TB
= fibrin web CSF, increased lymphocytes (mononuclear), low glucose, high protein
Mx of meningitis
GP
= benzylpenicillin IM
= urgent referral to hospital
A&E
= broad spectrum Abx (ceftriaxone IV/ benzylpenicillin IM, acyclovir if viral)
= consider IV dexamethasone (secondary to reduce cerebral oedema
Complications of meningitis
Hearing loss, sepsis, impaired mental state => meningoencephalitis, seizures
Meningitis vs encephalitis
Meningitis
= meninges
= bacterial, viral, TB
= consciousness impaired
Encephalitis
= brain parenchyma
= usually viral
= consciousness altered
Encephalitis presentation
Acute onset of febrile illness w/ behavioural, cognitive and psychological manifestations
= viral prodrome (rash, lymphadenoatphy)
= fever, headache
= altered mental state (memory disturbances, personality changes, psychiatric manifestations, impaired consciousness)
= FATAL if not treated
Causes of encephalitis
Viral (most commonly)
= HSV1/2, CMV, EBV, HIV, measles
Non-viral
= legionella, Lyme disease, listeria, malaria, TB, bacterial meningitis
Ix for encephalitis
LP Bloods EEG CT/MRI = shows oedemal hyperintense lesions = bitemporal oedema associated w/ herpes encephalitis
Presentation of raised ICP
Bilateral, gradual headache, thorbbing/bursting pain, worse in morning and when coughing/sneezing
Vomiting, altered GCS, seizures may also occur
O/E focal neuro sx, papilloedema*, Cushing’s reflex (increased sBP, bradycardia, irregular breathing), Cheyne-Stoke respiration
