Q

cluster vs paroxysmal hemicrania vs hemicrania continua vs SUNCT

A

cluster less frequent but longer (1-8 x per day, 15-180 mins each)
PH more frequent- more than 8 x per day, shorter - 15 mins)

PH responds to INDOMETHACIN very very well
Cluster- high flow oxygen and tryptan then prevent with verapamil

unilateral daily headache or continuous headaches with piercing brief headaches on top with redness or congestion or ptosis- responds to INDOMETHACIN

SUNCT is mini clusters lasting 60 seconds but 1-30 x per hour. No good tx.

2
Q

Brain imaging in trigeminal neuralgia

A

MRI

can be MS in a young person

3
Q

When not to give tryptans

A

hemiplegic migraine, severe CVD, bad hypertension

4
Q

treat transverse myelitis

A

IVMP

PLEX if fail

5
Q

Demyelinating neuropathies

A
CIDP/GBS
Charcot marie tooth 1
Anti MAG PN
MMN
POEMS
paraneoplastic
Amiodarone, chloroquine, TNF alpha blockers, tacrolimus, perhexilline
6
Q

Classic presentations of

acute axonal
chronic axonal
acute demyelinating
chronic demyelinating

A

AA- pain predom
CA- sensory before motor, longer first
AD- motor first then dysthesias
CD- weak and sensory together

7
Q

Anti GM1 ab

A

MMN

8
Q

Anti MAG Ab

A

MAG periph neuropathy
ab attack myalin assoc GP

use ritux

Mostly MOTOR

IgM so no PLEX

9
Q

CSF in neurosyphilis

A

SERUM treponemal tests remain reactive for life, regardless of if treated

CSF VDRL confirms diagnosis but not sensitive
CSF FTA-ABS sensitive but not specific

10
Q

order of loss of modalities with carpal tunnel

A

sensory latences then motor then axonal loss

11
Q

pronator teres vs CT syndrome

A

a patient with true carpal tunnel syndrome (entrapment of the median nerve within the carpal tunnel) will not have any sensory loss over the thenar eminence (bulge of muscles in the palm of hand and at the base of the thumb). This is because the palmar branch of the median nerve, which innervates that area of the palm, branches off of the median nerve and passes over the carpal tunnel. This feature of the median nerve can help separate carpal tunnel syndrome from thoracic outlet syndrome, or pronator teres syndrome.

12
Q

radial nerve gets compressed in the

A

axilla

13
Q

ulnar nerve gets compressed at the

A

elbow or palm with bicycle tools

14
Q

ramsay hunt- where is reactivation

A

geniculate ganglion

decrease recovery compared with bells but still 84% recover with slight defect

15
Q

most common cause of death in friederichs ataxia

A

HOCM

16
Q

Fragile X premutation

A

tremor ataxia syndrome later in life with neurocog deficit

17
Q

Reflexes in Friederichs vs SCA type 1

A

Spinocerebellar are hyper reflexic- AD

Friederichs are hyporeflexic and have loss vibration and proprioception- AR

18
Q

Hemiballismus

Chorea

A

subthal nuc

caudate (esp HIV), putamen, thal, subthal

19
Q

How to tell horners pre-ciliary from post ciliary

A

pre ciliary with phenylephrine both pupils dilate equally
post ciliary the horners dilates MORE

pre ciliary either brainstem symptoms or lung symptoms

post ciliary history of carotid disease or migraine

20
Q

Argyll robertson vs Adies pupils

A

AR pupils

  • syphilis
  • bilat small
  • accom not react
  • pre tectal nucleus
Adie Holmes
-unilateral tonically dilated
-reacts slowly to light but does accomodate
-loss DEEP TENDON REFLEXES
infection of ciliary ganglion
21
Q

What does ulnar nerve do in thumb

A

adductor policis
