What is a headache?
• a pain arising from the head or upper neck of the body. • pain originates from the tissues and structures that surround the
brain because the brain itself has no nerves that give rise to the sensation of pain
• The periosteum that surrounds bones• muscles that encase the skull• sinuses• eyes, and ears• meninges that cover the surface of the brain• spinal cord, arteries, veins, and nerves, all can become inflamed or
irritated to cause headache• pain may be a dull ache, sharp, throbbing, constant, mild, or intense

What u feel during attack
• Nausea• Vomiting• Diarrhea• Sweating• Cold hands• Light sensitivity• Dizziness• Neck pain
• Sensitivity to sound• Scalp tenderness• Pale complexion• Pulsating temple• Pressure pain• Vertigo• Difficulty thinking

Causes of headaches.
1. Traction or dilatation of intracranial or extracranial arteries.
2. Traction of large extracranial veins3. Compression, traction or inflammation of cranial and
spinal nerves4. Spasm and trauma to cranial and cervical muscles.5. Meningeal irritation and raised intracranial pressure6. Disturbance of intracerebral serotonergic projections

Life Threatening causes of acute headaches.
• Intracranial hemorrhage– Subdural hemorrhage– Subarachnoid
hemorrhage.
• Meningitis• Hypertensive
encephalopathy.

Hypertensive Encephalopathy
• Associated with high blood pressure, nausea, vomiting and blurred vision
• Usually associated with blood pressures of 200/130.
• Headache diffuse and worse in the morning and subsides during the day.
![Page 7: Headache](https://reader036.vdocument.in/reader036/viewer/2022062419/558b0d0fd8b42afc3c8b457a/html5/thumbnails/7.jpg)
Meningitis:useful signs and symptoms.
• The absence of fever, neck stiffness and altered mental status in a patient with a headache virtually eliminates the diagnosis of meningitis.
• In multiple studies the presence of neck stiffness on examination has a pooled sensitivity of 70%.

![Page 10: Headache](https://reader036.vdocument.in/reader036/viewer/2022062419/558b0d0fd8b42afc3c8b457a/html5/thumbnails/10.jpg)
Tension headaches• most common type of primary headache• women >men• Due to contraction of the muscles that cover the skull. • When the muscles covering the skull are stressed, they may
become inflamed, go into spasm, and cause pain. • Common sites include the base of the skull where the trapezius
muscles of the neck insert, the temples where muscles that move the jaw are located, and the forehead.
• because of physical or emotional stress• difficult and prolonged manual labor• sitting at a desk or computer for long periods of time
concentrating.

Causes of TTH( tension type headache)
• Some evidence that like migraine caused by serotonin imbalance but to a lesser extent than migraine.
• This would indicate that similar treatments would work.

Symptoms of tension h’ache
• Pain that begins in the back of the head and upper neck and is described as a band-like tightness or pressure. It may spread to encircle the head.
• The most intense pressure may be felt at the temples or over the eyebrows.
• usually is bilateral• not associated with an aura , nausea, vomiting, or sensitivity to
light and sound. • sporadically (infrequently and without a pattern) but can occur
frequently and even daily in some people. • allows most people to function normally, despite the headache.
![Page 13: Headache](https://reader036.vdocument.in/reader036/viewer/2022062419/558b0d0fd8b42afc3c8b457a/html5/thumbnails/13.jpg)

![Page 18: Headache](https://reader036.vdocument.in/reader036/viewer/2022062419/558b0d0fd8b42afc3c8b457a/html5/thumbnails/18.jpg)
Cluster h’ache
intro• occur daily for periods of a week or more • with long periods of time, months to
years, with no headache symptoms.• occur at the same time of day, often
waking the patient in the middle of the night.
• due to a sudden release of the chemicals histamine and serotonin in the brain
• The hypothalamus, an area located at the base of the brain, is responsible for the body's biologic clock and may be the location that is the source for this type of headache.
causes• tend to run in
families • triggered by changes
in sleep patterns• By Rx - NTG for heart
disease• smoking, alcohol,
chocolate and foods high in nitrites like smoked meat are responsible

Symptoms of cluster h’ache• headaches that come in groups (clusters) separated by pain-free periods of months
or years.• A patient may experience a headache on a daily basis for weeks or months and
then be pain free for years.• begins in adolescence but can extend to those in middle age.• pain typically occurs once or twice daily• Each episode of pain lasts from 30 to 90 minutes. • occur at the same time every day• awaken the patient at night from a sound sleep.• around or behind one eye. • patients describe the pain as feeling like a hot poker in the eye• The affected eye may become red, inflamed, and watery. • The nose on the affected side may become congested and runny. • patients with cluster headaches tend to be restless• They often pace the floor, bang their heads against a wall, can do suicide

Dx of cluster h’ache
• History• description of the pain• clock-like recurrence • If examined in the midst of an attack, the patient
usually is in a painful crisis and may have the eye and nose watering as described previously.
• If the patient is seen when the pain is not present, the physical examination is normal and the diagnosis will depends upon the history.
![Page 21: Headache](https://reader036.vdocument.in/reader036/viewer/2022062419/558b0d0fd8b42afc3c8b457a/html5/thumbnails/21.jpg)
Rx of cluster h’ache• very difficult to treat• headache recurs daily, there are two treatment needs. The pain of the
first episode needs to be controlled, and the following headaches need to be prevented.
• Initial treatment options may include one or more of the following:• inhalation of high concentrations of oxygen• injection of triptan medications, like, sumatriptan (Imitrex), zolmitriptan
(Zomig), and rizatriptan (Maxalt) which are common migraine medications;
• injection of lidocaine into the nostril;• dihydroergotamine (DHE, Migranal), a medication that causes blood
vessels to constrict; and• caffeine.

Prevention of the next cluster h’ache
• CCBs – verapamil , diltiazem• prednisone• antidepressant medications - lithium• antiseizure rx - valproic acid, topiramate• Life style modification• Avoid smoking /alcohol

cranial neuralgias, facial pain, and other headaches?
• Neuralgia -neur= nerve + algia =pain • Cranial neuralgia describes inflammation of
one of the 12 nerves that supply the motor and sensation function of the head and neck
• eg. trigeminal neuralgia which affects cranial nerve V (the trigeminal nerve) and can cause intense facial pain.
