Doorway information about patient
the patient is a 40-year-old woman who comes to the clinic due t headaches.
Vital signs
. Temperature : 37¡¦C
. Blood pressure ; 120/70 mmHg
. Pulse: 80/min . Respiratory rate; 19/min
Approach to the patient Most primary headache syndrome(eg, migraine, tension-type headache) usually present at a young age, and often become less severe with age . Onset 9 or significant change) at age> 40 justified greater concern. clinical features suggesting a potentially serious causes of headache are summarized by the mnemonic ¡§SNOOP¡¨ . -Systemic- symptoms ( eg, weight loss, fever) or disease (eg, cancer , HIV/AIDS) . -Neurologic symptoms (eg, cal deficits , altered sensorium) . Sudden -onset- . -Older- age at first occurrence . Change from previous headache
headache are usually diagnosed based on historical features . Examination is normal in most patients , and is primarily focused on ruling out uncommon diagnosis.
Differential diagnosis
Types of headaches
Migraine
Sex predilection - Female> male Family history - often present
Onset - variable location - Often unilateral Character - pulsatile & throbbing Duration - 4-72 hours Associated symptoms - Auras , photophobia, photophobia & nausea
Cluster
Male>Female No During sleep Behind eye Excruciating , sharp &steady 15-90 minutes sweating , facial flushing , nasal congestion m lacrimation &pupillary changes
Tension
Female> male
No under stress Band-like pattern around the head(bilateral) Dull , tight &persistent 30 minutes to 7 days Muscle tenderness in the head , neck , or , shoulders
Tension -type headache is the most common headache syndrome. It begins slowly over several hours and may act for days if not treated . Characteristic feature include a bilateral squeezing or pressure sensation , particularly at the temporal or occipital area . Associated symptoms (eg, nausea , visual changes ) are rare.
Sure migraine headaches are usually unilateral , have throbbing quality , and may e associated with nausea and visual disturbances .Migraines generally have a rapid onset and recognizable triggers such as caffeine , food/beverages (eg, chocolate, red wine) , or menstruation . migraines can be categorized as -without aura-(common migraine) or -with aura-(classic migraine) . An -Aura- is a transient neurologic (usually visual) symptom at the beginning of the headache . A history of ¡§flashing lights¡¨ or ¡§ wavy lines ¡¥ in the visual fields flooded by a throbbing unilateral headaches is virtually pathognomonic for migraine . Atypical migraines are common , and many nonstandard headache types(eg , sings headache ) actually represent migraine variants.
Secondary headaches are less common than primary headache syndromes but usually more ominous . major syndromes include: . Intracranial neoplasm: Morning or nocturnal headaches , worsened by bending over , neurologic deficits, or seizure . . Subarachnoid hemorrhage : Severe and sudden onset(¡§worst headache of mil life¡¨) , vomiting , loss of consciousness, neck stiffness . Angel closure glaucoma: Periorbital pain , vomiting , visual symptoms, abnormal ocular examination . Bacterial meningitis: Fever, confusion , nuchal rigidity . Giant cell arteritis : Age > 50 , temporal location , jaw claudication , shoulder or hip pain. . Hypertensive encephalopathy: Rapid rise in blood pressure (>180/120 mmHg)
HISTORY AND PHYSICAL EXAMINATION
In addition to the standard general medical history and physical examination , the following sections include the most common items that could be include in the evaluation of headaches.
History
history of present illness . Describe what your headaches feel like. . How long have you had these headaches? . Do they start gradually or suddenly? . Are they constant or intermittent? . How severe are they (scale1-10)? . Where do you feel the headaches? . Dose it hurt anywhere else(eg, jaw, neck)? . What were you doing when the headaches started? . Dose anything relieve the pain ? Make it worse? . Is there nay relation to foods or your menstrual cycle? . Do you have nausea or vomiting ? . Have you had headaches like this before? . Do you have ay working signs (eg, blurry vision, light flashes)before the headache starts? . Do you have nay fever or chills? . Have you had any weakness , tingling , or numbers in your arms or legs?
Past medical history . Do you have a history of cancer? . Have you been tested for HIV?
Family history . Is there anyone in your family with severe headaches?
Physical examination
HEENT . Examine fundi(hypertensive changes , papilledema) . Palpate scalp( temporal artery tenderness) . Examine years & tympanic membrane . Examine nose & throat
Neck . Auscultate ofr carotid bruits . Palpate for goiter or lymphadenopathy
Musculoskeletal . Palpate muscles in neck & shoulders for tenderness . Assess cervical range of motion
Neurologic
. Assess level of consciousness . Examine cranial nerves . Evaluate motor & sensory function in arms & legs . Romberg test . Check for cerebellar signs . Assess gait
Closing the encounter
Older patients or patients with atypical symptoms amy need additional diagnostic testing . in such cases , explain the possible causes and the goals of the tests. Give the patient an accurate assessment of the diagnostic uncertainly (eg ¡§ Your symptoms suggest benign migraines , but it its usual for someone your age to have headaches for the first time. I would like to do additional testing to be sure .¡¨) Explain that there are no tests to confirm migraine or tension-type headaches, but tests are done to rule out other disorders.
Diagnostic studies Young patients with a classic headache history may to need any diagnostic tests . If no tests are needed to confirm the diagnosis , write , ¡§ No studies indicated ¡§ in the Diagnostic Studies section.
Patients with focal neurogenic symptoms ( other than a stereotypical aura) or any off the ¡§ SNOOP¡¨ criteria should be considered for -neuroimaging- . Patient with suspected -subarachnoid hemorrhage- or signs of elevated intracranial pressure usually undergo an urgent -CT scan- . For less urgent indications , MRI has greater sensitivity.
-Lumbar puncture(LP) - may be considered in the evaluation of atypical or potentially serious headache syndrome . LP can confirm subarachnoid hemorrhage , but CT is done first . Otters indications for LP include-bacterial meningitis - and idiopathic intracranial hypertension (pseudo tumor cerebri)
Patients with possible -giant cell arteritis- should have -erythrocyte sedimentation rate or C-reactive protein- tests . Patients with fever or otters systemic symptoms should have a -complete blood count- . Patient with severe hypertension should have an -ECG- and -renal function studies- (blood urea nitrogen , creatinine , urinalysis).
