Pathophysiology of Meniere’s Disease

Meniere disease involves excess fluid and pressure in the labyrinth of the inner ear that episodically distends the structures of the labyrinth and damages the vestibular and cochlear hair cells

Causes of Meniere’s Disease–caused by viral infections or immune system-mediated mechanisms

Clinical Presentation of Meniere’s Disease- Early in the disease process-patients have intermittent attacks of vertigo that last from minutes to hours, often associated with nausea and vomiting.These episodes are commonly accompanied by pressure in the ear, low-pitched tinnitus fluctuating in intensity, and unilateral hearing loss

Diagnosis of Meniere disease is based on–clinical criteria and/or response to treatment; however, it is important to differentiate Meniere disease from other causes of vertigo and hearing loss

Physical Examination of Meniere’s disease should include

A thorough head and neck examination to exclude acute otitis media or another infectious process, a comprehensive neurologic examination a, On physical examination, sound will lateralize to the unaffected ear in the Weber test;in the Rinne test, air conduction will be greater than bone conduction.Spontaneous nystagmus occurs during attacks and may not be present between attacks.

Diagnostic criteria for Meniere’s disease include—two episodes of spontaneous vertigo lasting at least 20 minutes each, audiometrically documented hearing loss, tinnitus or aural fullness, and the exclusion of other causes NR 603 WEEK 1 QUIZ QUESTIONS ANSWERS

Diagnostic testing for Meniere’s disease include

an audiogram, and MRI to rule out central nervous system (CNS) lesions

Laboratory testing for Meniere’s disease include: thyroid-stimulating hormone (TSH), rapid plasma reagin (RPR) testing for syphilis, serum glucose, and Lyme serologies

Differential Diagnoses for Meniere’s disease include

Benign Paroxysmal positional vertigo, Vestibular neuritis, Vertebrobasilar insufficiency, Acoustic neuroma, Migraine headache

If Meniere’s disease is suspected a referral to _____________ should be made

otolaryngologist

The two major types of migraine are–migraine with aura and migraine without aura

Most common type of migraine–migraine without aura

Characteristics of a migraine, pounding or throbbing,moderate to severe in intensity, aggravated by PHYSICAL ACTIVITY, which is episodic, lasts 4 to 72 hours, may be associated with nausea, vomiting, photophobia, and phonophobia NR 603 WEEK 1 QUIZ QUESTIONS ANSWERS.

common triggers of migraines include, medication overuse, obesity, depression, stressful life events, sleep problems including snoring, weather changes, foods (cheese, chocolate), alcohol, change in altitude, delay or skipping of a meal, hormonal changes.

In a migraine with aura, when does the aura usually occurs

before the onset of head pain, although it can sometimes extend into the period of headache.

Visual auras can also be characterized by spots, shimmering bright lights, or areas of visual loss (scotomas).

A prodrome can be part of a migraine. What describes a prodrome

Several days before the aura or start of the head pain, the person may have feelings of doom or fatigue.

Acute tension-type headaches are described as- feeling like there is a tight band around the head. Nausea and vomiting are NOT present, pain can be mild to moderate in intensity

Most common trigger of a tension-type headache is stress.Acute tension-type headache is described as .a nagging headache that occurs FEWER than 15 days per month,is present most of the day, and may start after the person wakes up. It rarely awakens the person

Chronic tension-type headache is described as

is similar in presentation to the acute type but occurs more often than 15 days per month.

What are the characteristics of a cluster headache

is usually AWAKENS patients during the night with severe unilateral, retro–orbital pain. A cluster headache reaches maximum intensity in about 15 minutes and usually lasts about 90 minutes, although some can last 3 hours.

Subjective examination of a patient with headache should include, The history is the most important part of the evaluation, describing the duration, quality, and location of the pain. The presence or absence of any precipitating factors, or triggers, and the age at onset should be established. The presence of associated symptoms, such as nausea, vomiting, and photophobia, should be explored.

Are migraines familial? yes

Physical examination should include:cardiopulmonary and complete neurologic assessment with a major focus on the following:• Funduscopic and pupillary assessment• Auscultation of the carotid and vertebral arteries• Mental status examination• Palpation of the head, neck, and temporal arteries• Evaluation for any neck stiffness, focal weakness, sensory loss and gait• Vital signs

Serious symptoms and findings of a migraine include

a headache accompanied by a stiff neck; fever;malaise;nausea or vomiting; presence of any aphasia, weakness, or poor coordination

Other danger signs include the following • Onset of headache after the age of 50 years
• Asymmetry of pupillary responses • Decreased deep tendon reflexes• Headache described as “THE WORST EVER EXPERIENCED”• Personality change
• Onset of a new or different headache• Onset of a headache that progressively worsens• Papilledema• Painful temporal arteries

Lab tests for migraines include CBC, ESR, CRP, Thyroid function, Lyme titer, Rheumatoid factor, CSF cell count, Diagnostic imaging for migraines includes, CT scan, MRI*, CSF, cerebrospinal fluid;

Referral for those with migraines should be made when

suspected temporal arteritis, change in mental status, nuchal rigidity, neurologic deficit, or new onset of headache-especially over the age of 50.

Immediate emergency department referral for one with a migraine is indicated for

abrupt onset “THUNDERCLAP HEADACHE,” trauma, or headache with associated neurologic abnormalities on physical examination

Two areas of pharmacological management of migraines abortive and preventive

Preventive pharmacological management is indicated when patients if they are unable to deal with their attacks, they experience MORE THAN FOUR headaches a month, or, the attacks are prolonged and refractory to medicine

Abortive therapy is used to treat

the intensity and duration of pain during an attack and to manage associated symptoms, such as nausea and vomiting

First line treatment of migraines include

Simple analgesics, such as acetaminophen and aspirin, can represent first-line treatment in the management of mild to moderate headaches.

NSAIDS===if not relieved…..Corticosteroids,Triptans

When simple analgesics are ineffective in treating migraines, the next step would be to

combinine them with a short-acting barbiturate, such as butalbital (Fioricet, Fiorinal, Esgic),

Indications for Referral or Hospitalization for those with migraines

not easily controlled by routine headache medicines.• Rebound headaches or habituation limits outpatient therapy.• Headache is new and progressively worsening.
• Headache is described as the “worse headache of my life.”• Headache is affecting the patient’s quality of life.• Headache is accompanied by neurologic symptoms that last longer than 30 minutes or is accompanied by numbness or hemiparesis

Mild cognitive impairment (MCI) is thought to be a, transitional state between normal aging and dementia
