What should you test for in a pt that has new headache with fever, stiff neck or rash?
``` MRI / MRA Lumbar puncture for CSF Analysis Blood Tests -CBC -ESR -ANA -Lyme Titre ```
26

``` Tumor AVM Stroke Connective Tissue Disease -Antiphospholipid -Antibody Disease ```
27
What should you test for in a pt who has a focal neurologic symptoms?
``` MRI /MRA CT of Brain Blood Test -ESR -ANA -Other Connective -Tissue Disease Tests ```
28
What should be done in a physical examination for a headache?
High: maybe hypertensive headache Low: maybe ischemic headache
29
If the patient has nuchal rigidity what should be ruled out?
Subarachnoid hemorrhage
30
If nuchal rigidity if found, what is next emergency step? And what are the steps after that?
CT scan If normal follow iwth lumbr puncture for CSF analysis Fluid has blood transfer to neurologist Fluid is clear send to lab for cell count, gram stain, glucose, protein and culture Rule out meningitis
31
Signs and symptoms of meningism
The symptoms and signs of meningitis associated with an acute febrile illness or dehydration There is no actual infection of the meninges Also called meningismus or pseudomeningitis
32
If papilldema is found with headache in a physical what would you see?
Brain Tumor Meningitis Idiopathic Intracranial Hypertension (Pseudotumor Cerebri)
33
If papilledema is suspected in a physical for a headache what imaging and exams are required?
Neuroimaging | Lumbar Puncture for Pressure & CSF Analysis
34
Idiopathic Intracranial Hypertension | Aka Pseudotumor cerebri
``` Caused by cerebral edem Papilledema Elevated intervranial pressure Normal CSF on lumbar puncture Headache Nausea/Vomiting Normal Neurologic Examination ```
35
What are some etiologies of idiopathic intracranial hypertension?
``` Cerebral Venous Sinus Thrombosis Jugular Vein Thrombosis Addison’s Disease Chronic Obstructive Pulmonary Disease Hypoparathyroidism Severe Iron Deficiency Anemia ```
36
What is the most worrisome vital sign you can find in a headache and why?
Fever Meningitis Encephalitis Upper respiratory infection (most common)
37
What could you find in vital signs of blood pressure in a headache?
Hypertension | Hypotension
38
In the EENT exam what should you look for if there is a headache?
Infection or neoplasm Visually inspect the rtina for evidence of papilledema If present it most likely represents increased intracranial pressure
39
If you have an abnormal finding in a neurological exam, what is the first things to expect?
Intracranial pathology
40
What are the 4 big headache issues?
Migraine Muscle contraction headache Cluster headache Secondary headache disorders
41
Hemicrania Histroy
``` A lateralized headache Typical migraine pattern Cluster headaches Paroxysmal hemicrania If the headache is throbbing maybe associated with nausea, vomiting, photophobia, sonophobia Normal cause is migraine ```
42
In physical examination of Hemicrania what should you look for unilaterally?
``` Conjunctival injection Nasal congestion Rhinorrhae Normal neuro exam Cluster headache ```
43
If no other symptomology appears in Hemicrania, what can be assumed?
Muscle contraction headache
44
Cluster headache
A type of vascular headache that occurs in series of groups Can last several weeks to several months at the same time each year Spring and fall with pain free intervals Onset age 20 to 30
45
When do cluster headaches tend to occur?
At night generally lasting 1-3 in 24 hours lasting 15 min to 3 hours
46
How is the pain in a cluster headache described?
Excruciating, boring pain behind or around eyes
47
What are some cluster headache manifestations?
Pain affecting one side of the head but can spread Tends to switch sides Pain so terrible some try to kill themselves Patient prefers upright and moving rather than still and laying
48
What are some associated symptoms to cluster manifestations?
``` Conjunctival Injection Tearing Nasal Congestion Rhinorrhea Partial Horner Syndrome Sweating and Flushing (all occurring just on the side of the headache) ```
49
What are the signs of Horner syndrome?
``` Ptosis of upper eyelid Meiosis (pupil constriction) Anhydrosis and flushing on same side of face Narrowing of the palpebral fissure Retraction of eyeball ```
50
What is the etiology of horner's syndrome?
Ipsilateral brain stem lesion interrupting descending sympathetic pathways
51
What are the cluster headache variants?
Atypical pain location Multiple sharp jabbing pains (ice pick headaches) SUNCT Chronic continuous, sharply localized and unilateral pain
52
What are cluster headache triggers?
Alcohol consumption Smoking Sublingual nitroglycerin
53
What is the pathogenesis of a cluster headache?
Nucleus of trigeminal nerve descending to the spinal cord level becomes hyperactive unilaterally Internal and external carotid arteries dilate and are principle pain sources Horner syndrome - stretch/compression of sympathetic plexus around carotids Serum serotonin and histamine levels inc
54
Why should you not use OMT during a cluster headache?
During he headache it can exacerbate or prlong the pain
55
What could cervical somatic dysfunction secondarily cause in a cluster headache?
Hyperactivity of the sensory nucleus of the trigeminal nerve may be due to spinal cord facilitation
56
When should OMT be done for a cluster headache?
Between attacks: Treat cervical segments Treat any dysfunctions occurring in the upper 6 horacic segments and ribs Normalized sympathetic outflow to head and neck
57
What should you use to treat a cluster headache?
100% Oxygen by face mask for 15-20 min SubQ sumatriptan injection (6 mg) IM or IV dihydroergotamine (1 mg) Intranasal lidocaine (4-6% drops)
58
What is the short term prevention for a short term cluster headache?
Prednisolone and Trednisone (60-100 mg a day) slowly tapered over a period of a month Only can be used once a year Ergotamine tartrate (up to 4 mg a day in divided doses) risk of rebound headache
59
How does methysergide work to provide short term cluster headache prevention?
Effective 65-70% Only cluster Fibrotic syndrome in prolonged use -retroperitoneal, pleural, pulmonary, cardiac valvular fibrosis
60
What are the long term prevention for cluster headaches?
Verapmil - calcium channel blocker - (240-960 mg/day) used for hypertension or cardiac disease - ECG needed priot to use then 10 days after dose change Lithium carbonate - Takes a week to reach steady state Effective at blood lvl of 0.4-0.8 mol/liter Can be combined with others
61
Describe chronic paroxysmal hemicrania.
``` Similar to cluster headache Mostly female, occurs 10-30 times a day Short duration (2-25 min) with unilateral pain No nausea or vomiting Responds to Idomecthacin (NSAID) ```
