Dizzness Flashcards
Patient presents with dizziness
Central
e.g. brain stem or
cerebellar lesion
Peripheral
e.g. BPPV,
labyrinthitis
General
e.g. anemia
hypogl
Dizziness, red flags
Risk factors of stroke (DM, HTN, Smoking)
• Symptoms of increased intracranial tension,
loss of consciousness
• Neurological deficit (limb weakness)
• Nystagmus: changing direction, visual fixation
doesn’t abort the attack.
What is the difference between the red flag nystagmus and the associated?
At red flag visual fixation does not support attack
Why blood pressure is measured in dizziness
To see static orthostatic hypertension, which happens when systolic blood pressure decreases 20 and the diastoic decrease 10
the most common cause of the symptoms of
vertigo
BPPV
BPPV symptoms
Its
symptoms are repeated episodes of positional
vertigo, that is, of a spinning sensation caused
by changes in the position of the head
What is the treatment of BBV?
Canalith Repositioning Procedure
• Medical treatment: (Vestibular suppressants).
Commonly used to reduce symptoms of acute
episodes of vertigo, although there are no
RCTs to support its use;
– Betahistine (Betaserc): 8 – 24 mg once daily
– Anti-emetics in cases of nausea and vertigo.
Proper patient education:
– Two or more pillows while in bed.
– Avoiding sleeping on the affected side, and rising slowly
from bed in the morning.
– Avoiding looking up, such as at a high cupboard shelf, or
bending over to pick up something from the floor.
– Be careful when positioned in a dentist’s or hairdresser’s
chair, when lying supine, or when participating in sports
How to put vestibular neuritis
Rapid onset of severe resistant vertigo, nausea, vomiting, gait in stability spontaneous vestibular, nystagmus, positive head impulse get any stability without a loss of the ability to ambulate
Acute vertigo with hearing ipsi lateral facial paralysis. Ear pain vesciles in the auditory canal
Herpes zoster oticus
Spontaneous episodic vertigo last from minute to hours with unilateral tenets, tinnitus, hearing loss, ear, fullness, nausea, vomiting
Meniere dx
Traumatic peripheral vestibular injury after trauma, nausea, vomiting, vertigo, imbalance, improve over days
Labyrinthine concussion
Mention drugs that can cause vertigo
Antihypertensive antihistaminic
Antiepileptic benzodiazepines Diaa
Alcohol
Anti, arithmetic, anti-dementia
Test to diagnose bppv
Dix hall;ike maneuver
HINTS
Head impulse nystagmus test of skew
Distguish periphral from central nystagmus
Head impulse test positive
Peripheral cause
Horizontal nystagums is
Peripheral cause
Vertical nystagmus
Centralc ause
Teast of skew positive
Central cause
Management of vertigo
Use the for acute episodes not the brief as bbpv except when a frequency spells is very high
Antihistamine benzodiazepines animatics
