Q

Huntington’s Disease Treatment

Q

Corticobasal Degeneration

A

Asymmetrical onset showing:

  1. Akinesis
  2. Apraxia
  3. Alien hand syndrome
    - Pts. may have cortical involvement, increased DTRs, supranuclear gaze palsy

Neuroimaging shows contralateral loss of cortex

25
CT findings in Wilson disease
Hypodense regions in the basal ganglia | caudate, putamen, GP
26
PML
Presents as dementia, visual loss, and progressive hemiparesis -Oligodendrocytes contain eosinophilic intranuclear inclusions Tx: Cytarabine; vistidine
27
Sporadic vCJD on MRI
Anterior basal ganglia high intensity signal
28
New variant CJD MRI
High intensity signal in the pulvinar and thalamus
29
CADASIL
Dementia onset in young person; may also have recurrent strokes Probs have depression as well
30
Treatment of Sydenham's Chorea
Pimozide (dopamine antagonist)
31
Primary dystonia in childhood
Begins in the foot; responds to L-dopa
32
Treatment of a drug induced dystonia
Benadryl; Cogentin
33
PANDAS
Pediatric Autoimmune Neuropsychiatric Disorders Associated w/ Strep ***Tics that appear after a Strep Infxn ***DO NOT treat w/ antibiotics; treat w/ normal tic treatments
34
Narcolepsy tetrad
Sleep Attacks Hallucinations Sleep paralysis Cataplexy
35
Majority of sleep is spent in what stage
2 NREM
36
Antibody in generalized mg
Anti-MUSK
37

Anti-striated muscle ab
38
CMT Type 1
Demyelinating AD Inheritance Disorder of the PMP22 gene (peripheral myelinating) Presentation: Distal weakness and muscle wasting that affects the legs first; HIGH FOOT ARCHES AND HAMMER TOES *Might be described as champagne bottle legs
39
CMT Type 2
Axonal Type Damage to the axon Pts. can usually continue walking with ambulatory assistance
40
CMT Type III
Dejerine-Sottas Disease AR demyelinating neuropathy that leads to delayed developmental milestones
41
Miller-fisher variant of GBS
GBS that also causes Ophthalmoplegia, ataxia, facial weakness, and dysarthria *Pt will have anti-GQ1 antibodies
42
Chronic Inflammatory Demyelinating Neuropathy
Antibody mediated reaction w/ interstitial and perivascular infiltration of the endoneurium w/ T cells and macrophages Think of it like purely peripheral MS Tx: Immunosuppresants; IVIG; plasmapharesis -Good recovery due to them just being peripheral nerves
43
Gilenya
MS drug that sequesters lymphocytes into lymph nodes ADRs: Headache, diarrhea, lymphopenia, cough
44
Teriflunomide
Limits an enzyme in the pyrimidine synthesis pathway decreasing the proliferation of immune cells ***SEVERELY TERATOGENIC; if pt. becomes pregnant, remove from system w/ cholestyramine
45
Dimethyl Fumarate
Activates the Nrf2 pathway which responds to oxidative stress
46
Natalizumab
Monthly IV fusion that acts as an anti-a4-integrin blocking the trafficking of lymphocytes across the BBB ***CAN CAUSE PML
47
Transverse myelitis
Demyelination of the spinal cord Results in limb weakness, bowel and bladder dysfnxn, possibly automatic dysfnxn _Possible in patients w/ MS
48
Treatment of Neuromyelitis Optica
Rituximab
49
Oxybutinin
Anticholinergic used to treat a hypertonic bladder
50
Acute labyrinthitis
Typically associated w/ an infection and causes vertigo along with hearing loss -If bacterial abx; if viral, will resolve on own
51
Acute idiopathic vestibular neuropathy
Intense vertigo w/ head movements that arises due to a post-viral etiology Tx: Corticosteroids
52
Where are migraines thought to begin?
The Brainstem; is why you can get other symptoms with the aura
53

56
Ct stroke protocol
Ct of head w/o contrast Then CTA of head and neck Then CTP

Usually begins in foot Try treating with l-dopa If no response... It's probably idiopathic generalized torsion dystonia and it will generalize within 5 years
59
Chorea in a newborn
Could be glutamic acidemia Supplement with carnitine
