A

25
What's Trigeminal Neuralgia? Treatment?
- **Excruciating** sharp, **shooting, electrical quality** pain **occuring in paroxysms** in **one** or more distributions of the trigeminal nerve, often freqent through the day - Treatment is usually **carbamazepine** or **oxcarbamazepine**
26
A group of headache disorders characterized by unilateral trigeminal distribution pain that occurs in association with prominent ipsilateral cranial autonomic features, describes what?
Trigeminal autonomic cephalgia (TAC's)
27
What 5 types of headache disorders are classified as Trigeminal Autonomic Cephalgias (TAC's)?
1. Cluster HA 2. Paroxysmal hemicrania 3. Hemicrania continua 4. SUNCT syndrome 5. SUNA syndrome (similar to SUNCT, but with autonomic sx's)
28
What are the characteristics of SUNCT syndrome? Location? Onset and which sex is most commonly affected?
- Shortlasting, **unilateral**, neuralgiform headache attacks w/ conjunctival injection and tearing - Excruciating, burning, stabbing electrical HA in **periorbital** area lasting **seconds to a few mins**, occuring **frequently** throughout the day - Onset typically **over 50** in **men**
29
What is the treatment for SUNCT syndrome?
- Usually anticonvulsants - Particularly **lamotrigine**
30
Which HA type is **very similar to cluster HA**, but **shorter duration** (often only a few mins) and **increased frequency** (usually \>5 times per day)?
Paroxysmal Hemicrania
31
Paroxysmal Hemicrania (HA) is exquisitely reponsive to which drug?
Indomethacin
32
As a general rule, many physicians (including neurologists) believe that any person with HA should have what type of evaluation?
A **one-time**, thorough neuroimaging study (**CT head with AND w/o contrast** or **MRI** of head)
33
What's a good oral tx for someone experiencing multiple cluster HA's in a year?
Verapamil (Ca2+ channel blocker)
34
What medication is known to cause meningitis?
**lamotrigine** | (IVIg)
35
If a pt presents with s/s of meningitis, and you are unable to get an immediate LP, what should you do?
draw blood **give dexamethasone, ceftriazon IV, vancomycin IV** switch up to more specific tx once resutls are in
36
What are the key features of HSV1 Encephalitis?
**fever**, HA, impaired consiciousness **seizures**, focal neuro s/s focal abnormalities in **temporal lobes** tx: acyclovir \*up to 25% can develop recurrent neuropsychiatric sx (sometimes with associated ABs with secondary AI encephalitis)
37
What should be on the ddx if a pt presents with rapidly progressive encephalopathy or psych disturbances?
**AI Encephalitis** especially if assoc with seizures!! --\> some are well known causes of intractable epilepsy
38
How is AI Encephalitis typically tx?
combo of immune therapies: high dose steroids IVIg plasma exhange rituximab cyclophosphamide other immunosuppressive agents
39
Who does NMDA Encephalitis typically affect? What s/s are present?
**young or middle aged women** _rapid onset (\<3 mo) of 4 of the following 6:_ - abnormal psych behavior or cognitive dysfunction - speech dysfunction - seizures - movement disorders, dyskinesias, rigidity/abnormal postures - dec level of consciousness - autonomic dysfunction or central hypventilation
40
To dx NMDA Encephalitis, you need at least one of what two tests?
**abnormal EEG** (focal or diffuse or slow or disorganized activity, epileptic activity, or _extreme delta brush_) **CSF with pleocytosis or oligocloncal bands** and/or **NMDA R ABs**
41
What is NMDA Encephalitis commonly associated with?
**teratoma**
42
What is a hallmark of LGI1 Encephalitis?
more common in men **faciobrachial dystonic seizures** (brief, involve one side of face and ispi arm) sleep disturbance may see temporal lob abnormality in some pts acutely
43
Why is it important to tx LGI1 Encephalitis?
failure to tx results in **permanent brain damage** (esp short term membory) even with tx, 1/3 relapse _\*faciobrachial seizures do NOT respond to AEDs\*_
