15-17. Headaches + Serious Headaches Flashcards
When assessing patient with HA or CNS symptoms, what are the major parts of the brain that need to be screened?
Brain stem, cerebellum, cerebrum
When assessing patient with HA or CNS symptoms, what types of tests are used to screen each part of the brain?
Cerebrum: CN exam and consciousness test
Cerebellum: ataxia, vertigo, dysarthria
Brain stem: CN exam
What is a sample neurological exam?
BRAIN 1. Orientation, mental status exam and mood 2. Gait and cerebellar tests 3. Cranial Nerves II-XII and funduscopic exam PERIPHERAL 4. Light touch or sharp/dull (UE and LE) 5. Muscle testing 6. DTR 7. Pathological reflexes MENINGITIS ONLY 8. The jolt maneuver, Kernig, Brudzinski
What are the 3 types of ataxia and what causes the ataxia?
Sensory — corrupted input from peripheral nerves through posterior column of spinal cord. THINK: cord damage (posterior column), multiple NR damage (stenosis), polyneuropathy (diabetic neuropathy)
Vestibular — inner ear issue or CN VIII lesion. THINK: viral labyrinthitis, Meniere’s disease
Cerebellar — cerebellar lesion. THINK: MS, stroke, trauma, tumor, alcohol
What are some positive tests for sensory ataxia?
Gait: wide-based, tentative, watches foot placement
Station: eyes open = normal; eyes closed=abnormal *Romberg positive
Sensory exam: decreased sensation in distal extremities “glove and stocking”
Achilles DTR: depressed or absent
What are some positive tests for vestibular ataxia?
Gait: driven by the spins, true vertigo
Station: Romberg positive. Swaying. (eyes open & closed)
True vertigo: yes
Nystagmus: yes
What are some positive tests for cerebellar ataxia?
Gait: very wide-based and very irregular with arms out for balance. Afraid to walk. Trouble turning.
Station: Romberg positive (eyes open & closed)
Limb ataxia: various limbs
Truncates ataxia: flexed at waist
Achilles DTR: intact, but “pendular”
Speech: slurred
True vertigo: maybe
Nystagmus: maybe
How do you test for dysmetria in the UE and LE? What would be positive findings
UE: finger to target/finger to nose
(+) past-pointing, dysmetria as seen in ipsi lesion of cerebellar hemisphere
(+) terminal intention tremor
LE: heel to shin
(+) squiggly line of the heel limb
How would you test for stereognosis/graphesthesia? What lobe of the brain does it test?
Stereognosis: patient closes eyes. Place familiar object in patients hand. Ask to identify.
Graphesthesia: recognize letters or numbers drawn on skin.
Both test contra parietal lobe affecting association center (posterior column cord lesion).
What is papilledema and what can cause it?
Optic disc swelling due to increased intracranial pressure due to:
- optic neuritis
- tumor
- pseudotumor
What does a focal deficit refer to?
CN deficit is called a focal deficit and suggests patients headache is due to serious disease.
Describe the pronator drift and cerebellar drift and what they test
Pronator drift=eyes open; cerebellar=eyes closed.
Hold arms outstretched with hands supinated for 2 minutes.
(+) if patient cannot maintain posture or if 1 or 2 arms drop, internally rotate and flex at elbow while wrist flexes and hand pronates — early UMN disease indicator e.g. stroke
(+) Cerebellar lesion is if limb travels in any direction
What are 3 conditions that may cause spacticity?
Stroke
TBI
Spinal cord injury
Also: cerebral palsy/MS/amyotrophic lateral sclerosis, brain damage due to O2 debt, encephalitis, meningitis
Who is more likely to get cervicogenic vertigo?
30-50 yo
Females 60-90%
What is the diagnostic criteria for CGV?
- Dizziness (80-90%)
- Neck pain (must be present)
- Headache (common)
- Tinnitus (30%)
- Hearing loss (less common)
- Earache, feeling of fullness
- Unsteadiness when standing or walking increased by peripheral stimulation
What are 3 precipitating factors of vertigo?
- Trauma (80-90% patients who have chronic flexion-extension injury syndrome)
- Chronic MSK problems: C/S or shoulder dysfxn
- Anxiety
What are 3 key physical exam findings to support CGV?
- Neck movement may induce nystagmus
- Pain with palpation of lateral mass of atlas and suboccipital mm
- Induced by neck rotation while head is stationary e.g. Swivel test
How would you perform sitting swivel test?
Patients on a chair that swivels and closes their eyes.
- They shake their head from side to side. If symptoms of vertigo return, the vestibular system or cervical spine may be responsible. Wait until symptoms subside.
- Hold the patient’s head still while they swivel their body from side to side in the chair. If symptoms return, think cervicogenic vertigo.
What is Barre-Lieou Syndrome and what are common symptoms?
Suboccipital pain and vertigo precipitated by head rotation.
Some symptoms include hoarseness, fatigue, radiographic changes at C4-6, unilateral facial or eye pain.
What are some findings that helps DDX Barre-Lieou Syndrome from cervicogenic vertigo?
Visual symptoms, hoarseness, radiographic findings localized to C4-6
What is Meniere’s Disease and what are common symptoms?
Acute recurrent attacks (lasting several hours) of hearing loss, tinnitus, fullness in one ear.
What is thought to cause Meniere’s Syndrome?
Change in fluid volume (endolymph) within the labyrinth
What is the triad of exam findings suggestive of Meniere’s Disease?
No pain AND
- recurrent attacks of vertigo
- hearing loss
- tinnitus (ringing or buzzing)
How do you diagnose Meniere’s disease
By exclusion: physical exam, MRI, etc to R/O other diagnoses
What are some Tx for Meniere’s disease?
Diet is helpful: Low salt diet, No caffeine or alcohol
Your patient has fatigue and hoarseness, what do you suspect it is?
Posterior cervical sympathetic syndrome
Aka Barre-Lieou Syndrome
How would you treat cervicogenic vertigo?
CMT to stimulate C/S mechanoreceptors
STM for muscle dysfunction, rehab for proprioception, ROM and equilibrium
Others:
EMG biofeedback
Laser or US to increase circulation and improve healing rate of soft tissue
How long would you treat cervicogenic vertigo? And what percent of patients get better in that time period?
~ 1 month
In 4 weeks of treatment 85% of patients respond favorably with the interventions
In headache world, what is acute?
<10 days
What headaches should you consider in trauma patients? List the most serious one first
- Subarachnoid hemorrhage
- Subdural or epidural hematoma
- Posttraumatic headache / postconcussive syndrome / TBI
What percent of patients with subdural hematoma have a headache?
20% with chronic subdural hematoma have no identifiable etiology and can present with Sx up to 3 months from known traumatic event
How does the severity and onset of subarachnoid hemorrhage compare to subdural hematoma headaches?
Subarachnoid is sudden, severe, thunderclap
Subdural is mild to moderate, nonspecific and slower onset (can take up to 3 months for symptoms to present)
What patient population is most as risk of subdural hematoma due to trauma?
Elderly, alcoholics, epileptics, people on dialysis or blood thinners (warfarin), coagulation disorders
How long does it take from a traumatic event for someone to experience a headache due to subdural hematoma? What about acute posttraumatic headache (APTH)
Can occur in up to 80% of patients in 3 months after trauma
APTH: 7 days in about 1/2 patients and usually resolves in a few weeks
Post traumatic headache symptoms fall into 3 groups. Name the 3 groups and some examples from each group
Physical — headache, dizzy, double vision, blurred vision, nausea, sensitivity to light and noise, sleep disturbance
Mood/emotional — irritable, frustrated, depression, restless
Cognitive — forgetful, poor concentration, taking longer to think
