headache is caused by an abnormal metabolism of
serotonin, norepi, and dopamine
Headaches of new onset in the elderly tend to have a
secondary cause (tumor, bleed)
“worse headache of my life”
subarachnoid hemorrhage

diagnostics for headache
CT/MRI, sinus series, CBC, CMP, TSH, EEG, lumbar puncture
risk factors for migraine
family hx, female, alcohol, estrogen replacement
foods that can affect migraines
food containing tryptophan or tyramine (ripe cheese, red wine, chocolate)
neurotransmitter involved in migraine
serotonin
5 phases of migraines
prodrome, aura, headache, termination, postdrome
phase of migraine where pt experiences mood swings, fatigue, food craving, yawning
prodrome
phase of migraine where pt experiences visual disturbances, visual field cuts, flashing lights, zigzag patterns, floaters
aura
phase of migraine where pt experiences unilateral headache that is throbbing, anorexia, N/V, photophobia, vertigo
headache phase that lasts 4-72 hours
phase of migraine that usually occurs with sleep or meds
termination of headache
foods to avoid for migraines
MSG, nitrite-containing food (hot dog), tyramine-containing food
POUND symptoms of migraine
Pulsatile or throbbing One-day duration, or lasts 4-72 hours Unilateral Nausea or vomiting Disabling or intensity causing interruption of daily activity.
this type of headache rarely occurs in children and pregnancy
cluster headache
risk factors for cluster headache
male, age >30, alcohol intake, use of NTG, excessive caffeine/nicotine
commonly referred to as suicide headache
cluster headache
peak and duration of cluster headache
peaks in 15 min, lasts less than 3 hours
characteristics of cluster headache
deep, severe, unilateral, and episodic
associated s/s with cluster headache
lacrimation, rhinorrhea, ptosis, injected conjunctiva
typical time of onset for tension headache
after age 20, before 50
type of headache that involves precranial muscle tenderness
tension type headache
risk factors for tension type headache
stress, worry, jaw-clenching
s/s of tension type headache
bilateral pressure around head, nonthrobbing, palpable muscle tightness, stiffness in neck, upper shoulders, and scalp.
onset and duration of tension type headache
gradual and lasts 30 min-7 days
vertigo is accompanied by
nystagmus and ataxia
vertigo can be caused by
benign positional vertigo, labyrinthitis, and Meniere’s disease
difference b/t syncope and presyncope
in presyncope patient does not lose consciousness
vasovagal syncope is d/t
deceased cardiac output
meds that can cause syncope
antihypertensives antiarrythmics antidepressants diuretics phenothiazines vasodilators.
diagnostics for syncope
CMP, BP in both arms, 24-hr ECG monitoring, neuro exam, tilt test
Bell’s palsy affects CN
VII- facial
causes of Bell’s palsy
idiopathic, viral, exposure to cold, herpes zoster, Lyme disease
risk factors for Bell’s palsy
age > 30, Lyme disease, pregnancy, family hx, DM, herpes zoster
S/S of bell’s palsy
unilateral numbness and paralysis, sensitivity to sound, loss of taste
Diagnostic for bell’s palsy
CT to r/o stroke, EMG testing
trx for bell’s
eyedrops, patch on affected eye at night
trigeminal neuralgia affects CN
5
s/s of trigeminal neuralgia
severe pain in lip, gum, cheek that is worse with touch or changes in temp. pain occurs in bursts.
onset and duration of labyrinthitis
sudden onset that can last for up to 2 weeks. recurrence is common
in labyrinthitis, these are not affected
hearing and tinnitus
labyrinthitis can also cause
N/V, nystagmus
risk factors for stroke
HTN, HLD, DM, obesity, smoking, lack of exercise, alcohol, OCP, CV disease, afib, and carotid artery disease
stroke outcomes are improved it therapy is given within
3 hours of onset of symptoms
most common cause of ischemic stroke symptoms is occlusion of the
middle cerebral artery
Occlusion of the left middle cerebral artery produces
aphasia
occlusion of the right middle cerebral artery produces
neglect to opposite side of body
AHA stroke warning signs
numbness, confusion, vision problems, trouble walking, severe headache
goal BP and A1c for stroke prevention
less than 130/80 and 7%
two kinds of stroke
ischemic and hemorrhagic
TIA is characterized as
cerebral ischemia without infarction that lasts less than 24 hours
Begins with motor symptoms characterized by recurrent contractions of muscles in one part of the body.
partial seizure
begin in one part of the body and progress to contiguous body parts over seconds or minutes.
simple partial seizure
seizure that impairs consciousness
complex partial seizure
Seizure that is bilaterally symmetrical but without local onset
generalized seizure
brief arrest of activity and loss of consciousness.
petit mal seizure
seizure where muscle movements are repetitive.
myoclonic seizure
causes of seizures
alcohol withdrawal, brain tumor, hypoxia, stroke, fever, head injury, meningitis
highest incidence of seizures is in
children and elderly
Inflammation of the brain and spinal cord caused by infection with bacteria, viruses, and fungi.
