Q

What are the features of subarachnoid haemorrhage?

A

Sudden generalised headache

Q

What is initial treatment for suspected SAH? How do you diagnose subarachnoid haemorrhage?

A

Nimodipine and BP control.

High risk of a further bleed
.
Early neurosurgical assessment will confirm the bleed
and establish the cause.

CT brain, Lumbar puncture (will be pink) (RBC and xanthochromia) and MRA, angiogram.

Blood is white on CT

48
What is chiari malformation?
Normal brain that just sits very low within the skull
49
How doe chiari malformation cause headache?

What is trigeminal neuralgia?
Electric shock like pain in the distribution of a sensory nerve. Often triggered by innocuous stimuli. Any division of the trigeminal can be affected. Neurovascular conflict at the point of entry of the nerve into the pons. Can be symptom of M.S.
