Q

What are the low risk features for a Headache Complaint?

A

Age <= 50 years

Features typical of primary HA

History of similar HA

No abnormal neurologic findings

No high-risk comorbid conditions

No new or concerning findings on history or examination

17
Q

What are the Danger Factors of a headache?

A

SNOOP

Systemic symptoms, illness, or condition (fever, weight loss, cancer, pregnancy, immunocompromised state)

Neuro symptoms or abnormal signs (confusion, papilledema)

Onset is new (particularly for age >= 50 years or sudden (e.g., thunderclap)

Other associated conditions (head trauma, illicit drug use, worse with valsalva maneuvers, precipitated by sex, etc)

Previous headache history BUT WITH HEADACHE PROGRESSION OR CHANGE

18
Q

When is there a need for an emergency evaluation for a headache?

A

Sudden thunderclap headache

Acute or subacute neck pain or headache with Horner Syndrome and or neuro deficit

HA with suspected meningitis

HA with global or focal neurologic deficit or papilledema

HA with orbital or periorbital symptoms

HA and possible carbon monoxide exposure

19
Q

What is VERTIGO?

A

Sesnation fo self motion when they are not moving or a distorted self motion during normal head movement

Can result from asymmetry within the vestibular system

Disorder of the peripheral labyrinth of its central connections

Distinction between vertigo and dizziness has limited clinical usefulness

20
Q

How do you evaluate dizziness?

A

TiTrATE

3 distinct components:

TIMING of the symptom (onset, duration, and evolution of symptoms)

TRIGGERS that provoke the symptom (Actions, movements, or situations)

AND a TARGETED EXAMINATION

21
Q

What are the three clinical scenarios for dizziness?

A

Responses place dizziness in one of three clinical scenarios:

Episodic Triggered symptoms

Spontaneous Episodic Symptoms

Continuous Vestibular Symptoms

22
Q

What are Episodic Triggered Symptoms?

A

Brief Episodes of intermittent dizziness lasting seconds to hours

Common triggers are head motion or change in body position

MOST LIKELY: Benign Paroxysmal Vertigo (BPPV)

23
Q

What are Spontaneous Episodic Symptoms?

A

Dizziness lasting seconds to days

No triggers, so other elements of the history help determine DDx

If dizziness is associated with symptoms of unlateral hearing loss - Meniere Disease (my ear!)

If dizziness is associated with symptoms of migraine headache - Vestibular Migraine (MOST COMMON IN CHILDREN)

If dizziness progresses from episodic to continuous - Psych Diagnosis

24
Q

What are Continuous Vestibular Symptoms?

A

Dizziness lasting Days to weeks

Classic symptoms = continuous dizziness or vertigo with N/V, nystagmus, gait instability, and head motion intolerance

Often related to exposure to trauma or toxin

  • In 23% of older adults with dizziness, medications are the cause
  • Use of 5 or more meds is associated with increased risk for dizziness

If no toxin or trauma exposure, consider vestibular neuritis or central etiologies

25
Q

What is the Dix-Hallpike Maneuver?

A

Test for Benign Paroxysmal Vertigo (BPPV)

Pt sits on exam table facing forward, eyes open

Physician turns the patients head 45 degress to the RIGHT

Physician supports the patients head as the patient lies back quickly from a sitting to supine position

ending with the head hanging 20 degrees off the end of the exam table

Pateint remains in this position for 30 seconds

Patient returns to upright position and is observed for 30 seconds

Maneuver is repeted with patients head turned LEFT

Positive test is indicated if any of these maneuvers trigger vertigo with or without nystagmus

26
Q

What causes BPPV?

A

Occurs when loose canaliths get stuck in semicircular canals

27
Q

Who is affected by BPPV?

A

Any people at any age

Most common between ages 50-70 years

No obvious cuase found in most older people

Head trauma is a consideration in younger people

28
Q

How do you treat it?

A

Treatment consists of Epley Maneuvers in the office

Home treatment with Brandt-Daroff exercises can also help

No role for pharmacological treatment

29
Q

What is vestibular Neuritis?

A

Second most common cause of vertigo

Most commonly affected ages 30-50 m=F

Symptoms include rotatory vertigo with apparent movement of objects in visual field

Horizontal nystagmus to nonaffected side

Abnormal gait with tendence to fall to affected side

Dix-Hallpike not useful, symptoms NOT POSITIONAL

Lasts a few days generally

Less severe symtpoms can linger a couple months

Combo of anti-emetic, anti-histamine, or benzodiazepines can help

30
Q

What is Meinere Disease?

A

Vertigo with hearing loss (+/- tenitus)

Any age, most common at 20-60

Vertigo so severe often requires bedrest

Any accompanying HA and hearing loss can be worsened during an attack

Exact cause unknown

Can have BPPV and Meneire disease
- Dix-Hallpike test can be positive

31
Q

What is Vestibular Migraine?

A

Episodic Vertigo in patient with history of migraine suggests this etiology

Kids: most common form of vertigo

Adults: 3x more common women
- ages 20-50, fam history +

Treat with stress relief adequate sleep/exercise, consider medications to block migraine or suppress vestibular functions
