Last 1-3 days
What are migraines associated with?
Nausea
Vomiting
Visual disturbances
How can you tell if a headache is a sinus headache?
Pain around eye or cheek
What makes a headache a cluster headache?
Unilateral pain, always on same side of head, excruciating
What does temporal arteritis feel like?
Throbbing pain
What is presyncope?
Light headed/swimming sensation or feeling of fainting or falling
What is presyncope caused by?
Decrease of blood flow to the brain
What is vertigo?
True rotational spinning
Types of vertigo and what they mean
Objective - pt feels like the room is spinning
Subjective - pt feels like they are spinning
If a pt has vertigo with unilateral hearing loss, what could that mean?
Meniere disease
What is disequilibrium?
Shakiness or instability when walking, related to musculoskeletal disorder or multi sensory deficits
Pt has acute onset of neck stiffness with HA and fever
Meningitis
If pt has lumps or swelling in neck and feels tenderness when palpating
Acute infection
If pt has persistent lump
Be suspicious of malignancy
If pt age 40+, assume malignancy until proven otherwise
If pt has history of radiation, what are they at an increased risk of?
Risk for salivary and thyroid tumors
Trouble swallowing
Dysphagia
Pt has an abnormally small head
Microcephaly
Pt has an abnormally large head
Macrocephaly
Obstruction of drainage of cerebrospinal fluid that results in accumulation, increasing intracranial pressure and enlargement of head
Hydrocephaly

**How does the thyroid negative feedback system work?
1- hypothalamus secretes TRH, which
2- acts on anterior pituitary to secrete TSH, which
3- directs thyroid gland to produce T3 & T4 hormones. When T3 & T4 are high in blood stream, they
4- direct the pituitary and hypothalamus to shut off their signaling hormones
When T3 & T4 levels are low, pituitary sends out increasing TSH to stimulate new production of T3 & T4
