ملاحظة بالنسبة للـ nystagmus :

أكو Menetrier's disease همين، بس هذا يصير بالمعدة. Ménière يصير بالاذن

.

Etiology:
It is caused by endolymph (the fluid filling the cochlea & vestibule) accumulation in the vestibular apparatus. Possibly due to trauma, previous infection, or auto-immunity.

Signs and symptoms
It has a triad of symptoms:

• Spontaneous vertigo that lasts for hours (rarely for a day), and is not induced by head movement.
• Tinnitus
• Hearing loss that starts at low frequencies and progresses further.

.

Just to be clear
Positional vertigo: occurs with change in position (head movement).

Spontaneous vertigo: occurs spontaneously without head movement

Diagnosis is based on:

• two or more spontaneous vertigo episodes that last 20 minutes to 24 hours.
• hearing loss in low to mid frequencies in the affected ear, as measured by audiometry.
• tinnitus or feeling of fullness in the ear.
• Symptoms not better accounted for by another vestibular diagnosis

The dx is clinical, and usually with the help of audiometry.
Imaging studies are required only to rule out other diseases.

It's a special type of migraine, basically. You'll find it in patients with a history of migraine.

If a patient comes in with a vertigo that lasts for hours, and he has a hx of migraine, then you should think of this.
