Brain Syndromes Flashcards
Where are injuries causing Gerstman syndrome situated?
Dominant parietal lobe
Describe classical findings of Gerstman syndrome
*Agraphia w/o alexia
*Left-right confusion
*Digit Agnosia
*Acalculia
What syndrome is associated to the dominant parietal lobe?
Gerstman syndrome
Where are injuries causing Parinauds syndrome located?
Dorsal midbrain.
anterior to the pineal region.
Signs of Parinauds syndrome?
- Convergence nystagmus (rythmical retraction on cenvergence) retractorius
- Dissociative light-near response (light funkar inte, near funkar)
*Upgaze palsy (sunset sign)
What syndrome is associated to injuries in/infront of the pineal gland?
Parinaud syndrome
Where are injuries causing Wallenberg syndrome localised?
From the PICA area (VA)
What symtoms are seen in Wallenberg syndrome?
- injury to nucleus ambiguus give ipsilateral palatal, pharyngeal and vocal cord paralysis
- Additionally:
*IPSIlateral FACIAL numbness, *CONTRAlateral TRUNCAL numbness.
Ipsilateral horners syndrome.
+Vertigo, nausea, vomiting and occasionally hick-ups.
Where is the injury in Webers syndrome?
Usually caused by a Lacunar infarction.
Medial portion of the midbrain.
What are the symtoms of Webers syndrome?
- CN III palsy
- Contralateral hemiparesis
- might be relatively pupil sparing.
Medial portion of midbrain
What are the symtoms of Benedicts syndrome?
presence of an
* bilateral oculomotor nerve (CN III) palsy and *cerebellar ataxia including tremor and
* involuntary choreoathetotic movements.
-red nucleus syndrome or paramedian syndrome
Where is the injury in Benedicts syndrome?
Like for Webers syndrome, its a lesion in the midbrain area. In this case involving the red nucleus, brachium conjunctivum (superior cerebellar peduncle) and CNIII fascicles.
What is sturge weber syndrome?
A rare congenital disorder.
* portwine stain of V1 area and a
*ipsilateral intracranial leptomeningeal ANGIOMA
as well as *glaucoma, *seizures and *poor intellectual function.
Where are injuries causing millard gubler syndrome located?
In the ventral pons. Superior to the pyramidal decussation,
by the fascicles of CN IV and motor VII.
