Headache

From Mediwikis
(Redirected from Headaches)

Migraine

Adolescent onset, due to pulsation of intracranial arteries.

Can last 1-72 hours

Symptoms

  • Unilateral headache
  • Prodome (patient can predict onset - e.g. cravings, sleep, appetite and mood changes)
  • Aura- "zigzag" or other types
  • Nausea & Vomiting
  • Photophobia

Common Triggers- CHOCOLATE:

  • Cheese
  • Oral contraceptive pill
  • Caffeine(and withdrawal)
  • Alcohol
  • Anxiety
  • Travel
  • Exercise

Prophylaxis

  • B-blockers
  • Amytriptyline.
  • Find and avoid triggers

Treatment

  • Rest (resolves with sleep)
  • NSAIDS[1]
  • Triptans.

Tension Headache

Older schoolchildren- "Band" of pressure, worse at the end of the day. Benign, give simple analgesia

Symptoms

  • Bilateral headache - often described as "band" of pressure.
  • No focal neurological symptoms

Treat

  • Simple analgesia
  • Stress relief
  • Acupuncture[2]

Subarachnoid Haemorrhage

Bleeding into the sub-arachnoid space caused by head injury (85%), cerebral aneurysm rupture (most cases berry aneurysm) or ateriovenous malformation (AVM).

Risk Factors: Hypertension, Smoking, Alcohol, anticoagulation

Symptoms

  • “Thunderclap headache” - Sudden onset, intense pain to occiput. 
  • Commonly described as like ‘a baseball bat to back of the head’ and ‘first and worst headache’.

Signs

  • Seizures
  • Vomitting
  • Reduced GCS.
  • Stiff neck
  • Kernig's sign
  • Cranial Nerve palsy/other focal neurology

Management

  • Emergency referral to neurovascular surgery for intervention e.g. coiling/surgical clipping
  • CT is essential before lumbar puncture (LP).  Doing an LP on a patient with raised intracranial pressure could cause a phenomenon called ‘coning’ – i.e. brainstem compression and damage as a result of herniation through the foramen magnum. 
  • LP should be done ideally >12 hours after bleed as bilirubin in the SAH takes time to breakdown. The xanthochromia in CSF confirms SAH. 
  • Nimodipine is given for vasospasm  
  • BEWARE of Complications: Rebleeding is very common!!!!  

Subdural Haemorrhage

Subdural haemorrhage is bleeding from bridging veins between the dura and arachnoid layers. Most are formed by trauma!

Risk factors: Elderly (as a result of brain atrophy, the bridging veins are more vulnerable) , Alcoholics, Epileptics (more likely to fall), Anticoagulant therapy

Symptoms

  • Fluctuating consciousness
  • Personality Change
  • Sleepiness

Signs

  • Raised ICP
  • Seizures
  • Focal neurological symptoms
  • BEWARE: Signs and symptoms can take months to appear!

Management

  • Organise CT/MRI Scan
  • Refer to neurosurgery
  • Patient might need Craniostomy /Craniotomy

Giant Cell Arteritis

Giant cell arteritis (GCA) is a large vessel inflammatory vasculitis, most commonly affecting the temporal artery. Suspect GCA in patients >50 with a new headache – if untreated it can lead to visual loss. GCA is strongly associated with polymyalgia rheumatica (symmetrical pain and stiffness in the shoulder and pelvis).

Symptoms

  • Headache
  • Tender scalp and neck
  • Jaw claudication when chewing
  • Weight loss and malaise
  • Unilateral visual loss

Investigation

  • ESR (and to a lesser extent CRP)
  • Temporal artery biopsy

Treatment

  • Initiate high dose corticosteroids as soon as GCA is suspected (before biopsy) –continue for 4 weeks. Corticosteroids are usually continued at a lower dose for the next year.
