(21 cards)
Gerstmann’s Syndrome
Lesion of dominant parietal lobe: acalculia, agraphia, finger agnosia, left-right confusion, inferior homonymous hemianopia
Anton’s syndrome
patient with cortical blindness denies blindness
Mobius syndrome
-horizontal gaze palsy with 6-9 palsies
Ocular motor apraxia
- Acquired from is called what?
- Findings?
- Associations?
- saccadic palsy
- impairment of voluntary horizontal eye movements
- acquired form: Balint’s syndrome
- head thrust towards desired direction of gaze
- abnormal OKN (fast phase absent)
- associations: Gaucher’s dz, MR, ataxia-telangectasia, Wilson’s disease, hypoplasia of corpus callosum
Fisher syndrome
-Etiology?
one and a half syndrome
- CN 6 and ipsilateral MLF (only movement is abduction of contralateral eye)
- most commonly due to stroke
Dorsal midbrain syndrome
- Etiology?
- Dx
- Tx
- aka Parinaud’s syndrome
- most due to pineal tumor
- supranuclear paresis of upgaze, convergence retraction nystagmus on attempted upgaze, Collier’s sign
- Dx: MRI, Tx: XRT
Progressive supranuclear palsy
-progressive vertical and horizontal gaze palsy, eventual frozen globe
Skew deviation
- vertical misalignment of visual axes due to imbalance of prenuclear inputs
- hypodeviated eye ipsilateral to lesion
- etiology: brainstem infarct, MS, ICP, IIH, cerebellar dz, VBI
Nothnagel’s syndrome
- CN3 fascicle and superior cerebellar peduncle
- CN3 palsy and cerebellar ataxia
Benedikt’s syndrome
- CN3 fascicle and red nucleus
- CN3 palsy and contralateral hemitremor and decreased sensation
Weber’s syndrome
- CN3 fascicle and pyramidal tract
- CN3 palsy and contralateral hemiparesis
Claude syndrome
-Nothnagel’s and Benedikt’s
Millard Gubler syndrome
- CN6 and 7 fascicles and pyramidal tract
- contralateral hemiparesis
Raymond’s syndrome
- CN6 and pyramidal tract
- contralateral hemiparesis
Foville’s syndrome
- CN5,6,7 and sympathetics
- horizontal conjugate gaze palsy
- ipsilateral Horner’s
Mobius syndrome
-CN7 lesion, supernumerary digits, skeletal abnormalities, MR
Gradenigo’s syndrome
- localized inflammation or extradural abscess of petrous apex (mastoiditis)
- CN6 palsy with ipsilateral decreased hearing, facial pain, facial paralysis
Pseudo-Gradenigo’s syndrome
-nasopharyngeal Ca, cerebellopontine angle tumor, petrous bone fx, basilar aneurysm, clivus chordoma
Devic’s syndrome
-bilateral optic neuritis and transverse myelitis
Pseudo Foster-Kennedy syndrome
-sequential AION
Foster-Kennedy syndrome
- frontal lobe mass
- causes anosmia, ipsilateral optic atrophy and contralateral ON edema
