Headache is the most common pain syndrome. It is also the most frequent
symptom in neurology, sometimes described as “the most common
complaint of civilised man”.
Two thirds of the population suffer from headaches; a fair proportion
of these are caused by disorders of the neck.
In most cases the headaches can be successfully treated and recurrences
prevented.
How does it happen?
The brain is often fooled into thinking it has a headache by the
complex interconnection of nerves supplying the joints, muscles,
and ligaments of the upper part of the neck.
Brain tissue itself has no nerve endings and cannot feel pain.
Pain may arise from cranial sinuses, cerebral arteries, spinal cord
coverings, cranial nerves, as well as upper cervical nerve roots.
Disorders in the upper neck can refer pain up into the head.
Neck pain referring to the head may arise from joints, ligaments,
muscles or nerve tissue.
A common pattern in neck-headaches has tension and aching beginning
at the top of the neck.
This pain may worsen and spread into the back of the head, temples,
forehead, and behind the eyes.
Dizziness and lightheadidness may also be present and made worse
by head and neck movement.
Physiotherapists are experts on neck-headaches.
They can perform treatment as well as give valuable advice on prevention.
Treatment is aimed at the upper joints of the neck and may involve
mobilisation, manipulation, massage, exercise and postural correction.
Teaching prevention is also important; posture, both at home and
at work is very important (workplace assessments may need to be
carried out).
The type of pillow you sleep with can also contribute to headaches.
It may be necessary for people who suffer from numerous headaches
to keep up with a specific stretching and strengthening program
for the joints and muscles of the neck.
Other brain facts
-
The average human brain weighs about 1400 grams (3 lb).
-
When the brain is removed from the skull, it looks a bit like
a large pinkish-gray walnut.
-
The brain can be divided down the middle lengthwise into two
halves called the cerebral hemispheres.
-
Each hemisphere contains more than 7 billion nerve cells but
the brain only requires 10 watts of electricity to run.
-
The folding of the cerebral cortex increases the amount of cerebral
cortex that can fit in the skull.
-
The total surface area of the human cerebral cortex is about
2500cm2, about the size of two full pages of this paper.
-
In comparison with other animals we fair much better than a
rat at 6cm2 but worse than the Bottle-nosed dolphin at 3745cm2
or the African elephant at 6300cm2.
