Causes Of Headaches
causes of headaches:
headache : often associated with narcotic drug dependency
headache : males more commonly affected
headache : the second most common headache, genetic factors
play an important role
type headache : the most common headache
: caused by pressure on the meninges
tumors : increased pressure from tumor
aneurysm : triggered by blood vessel
pain : radiating via trigeminal nerve
headache : electrolyte disbalance causes it
hematoma : caused by pressure on the meninges
cell arteritis : triggered by temporal
: dilatation of brain vessels causes it
: low blood sugar triggered
: direct irritation of meninges
abnormalities : neck pain can cause headaches
headache : headache from trauma to head
hematoma : direct pressure on meninges causes it
joint disease : trigeminal nerve mediated headache
neuralgia : common after shingles (herpes zoster)

are very common and can be divided into primary headaches that occur
spontaneously and secondary headaches that are due to another underlying
medical cause. The table above gives more details and provides links to more detailed
Another cause for headaches can be
the development of a brain tumor.

Another cause can be the accumulation of blood in
the subarrachnoid space from the rupture of a cerebral
aneurysm. Use this link to get to this chapter.
Headaches can be caused by dental abscesses, root canal
disease, underbite, overbite and night time tooth grinding.
can cause headaches. The common denominator is an irritation of the powerful trigeminal
nerve, which supplies teeth with sensitive nerve fibers. This can trigger the
brain stem and the cortex of the brain to produce a severe, overpowering headache.
See your dentist, if you are aware that your teeth are the cause of this headache.
Nature equipped us with a built-in alarm system and we better pay attention to
Headaches in the setting of
hemodialysis for kidney failure can occur from too little sodium concentration
in the dialysis fluid (Ref.4, p. 1511). Another mechanism of developing a headache
in association with hemodialysis is when the blood pressure has significantly
dropped about 4 hours after the start of hemodialysis (Ref.4, p. 1512).
Giant cell arteritis has been discussed in
another chapter. This is a rheumatological disease where there is a strong association
with polymyalgia rheumatica. Headaches are often associated with a condition,
called temporal arteritis. This, if not treated can lead to blindness of the eye
on the side of the headache. Use this link to get to this chapter: Polymyalgia
rheumatica and temporal arteritis.
The mechanism of
headaches caused by high blood pressure is due to swelling of the meningeal membranes
from congestion based on uncontrolled hypertension.

Neck abnormalities come in many different forms.
There are inborn (congenital) neck abnormalities with malformations in the lower
cervical spine area (6th and 7th vertebral bodies) or at the upper end of the
cervical spine in the first and second vertebral body area. These abnormalities,arthritic
changes and changes from trauma to the neck can lead to chronic neck
pain, which has been dealt with in more detail under this link in
another chapter. All of these problems can lead to headaches, mostly of the variety
of the tension type headache.
