Types of Headache
The most serious causes of an acute headache are
Other causes include:
This is a list of causes of recurrent, acute headache:
- Migraine - this is by far the most common and can be debillitating for the patient during an episode
- Cluster headache
- Coital headache
- Tension headache
- Medication-induced headache
The most important cause of a subacute headache is giant cell arteritis. Easy to confirm diagnosis, this can be fatal if not picked up.
The first condition to rule out is raised intracranial pressure (ICP). This is can be indicative of a number of serious conditions (e.g. hydrocephalus, space-occupying lesions which could be a brain tumour) or of benign raised intracranial pressure.
Headache as a Condition
Pain (or ache) in the head region.
The cause of the pain depends on the reason for the headache. In the case of raised intracranial pressure, the brain itself can't feel pain because it doesn't have pain receptors. However, it presses on the meninges, causing pain.
Other causes of headache are often through muscular, arterial or venous processes.
There are specific risks for the different types of headache - check out their pages above to find out more. However, overall:
- Being female
- Stressful job
- Anxiety and depression
Red Flag symptoms
- Very sudden onset, severe headache - this could be a subarachnoid haemorrhage.
- Accompanied with stiff neck and other signs of meningism.
- Increasingly bad headaches, worse in the mornings, accompanied with progressive neurological signs and vomitting or signs of raised ICP, such as papillodoema.
- Associated with pain in the eye or ear
- Recurring headache in children
The exact symptoms are more likely to be related to the type of headache. Click the links on each type to learn more:
- Migraine - headache, often preceded with sensory aura. Vomitting, nausea and photophobia common.
- Cluster headache - very severe headache, present around once a day for a few hours in clusters of several weeks, followed by months free of headache until the next cluster.
- Tension headache - bilateral pain present all the time. Often related to muscle tightness in neck,head or pain. Associated with stress.
- Medication-induced headache - ironically often related to overuse of pain relief relief for headache! Also linked with the oral contraceptive.
The majority of headaches need no investigation. In more worrying red flag cases, a CT is recommended.
Commonly, one uses normal friendly analgesics
The vast majority will be fine. Many go on to suffer chronic headache, but only to very few is this a hugely debilitating condition. However, if lulled into a false sense of security by this page, you actually do have a massive brain tumour that you ignore, your risk is a little higher.
