what are the pain-insensitive structures in the head
- brain parenchyma
- ependyma
- choroid
- pia
- arachnoid
- dura over convexity
- skull
what are the mechanisms of headaches
- intra/extracranial artery distention, traction, dilation
- traction/displacement of large intracranial veins and their dural envelope
- compression, traction, or inflammation of cranial (CN II, III, V, VII, IX, X) and spinal nerves
- meningeal irritation and increased ICP
deform, displace, or exert traction on vessels and dural structures at the base of the brain even before there is inc ICP
intracranial mass lesion
presentation of headaches caused by increased ICP
bioccipital/bifrontal headaches that fluctuate in severity and worse in supine
what can cause dilation of intracranial/extracranial arteries and possible sensitization
seizures, alcohol ingestion, nitroglycerine and nitrates, MSG
this is the throbbing or steady headache wherein increased pulsation of meningeal vessels activate the pain sensitive structures within their walls or around the base of the brain
febrile illness
this mechanism of cranial pain present with extremely rapid rise in BP, along c cough & exertional headaches
dilation of intracranial or extracranial arteries
projection of basilar artery thrombosis
occiput
where does ICA dissection and MCA occlusion project to

true
