🗯 Notes on focal neurological deficits :- * Part 1


■ stroke is the most common cause of focal neurological deficits

■ Heart is the most common source of ischemic stroke ( embolism )

■ the most common cause of ICH is HTN

■ the most common artery of causing ICH is MCA

■ Non-contrast CT of the brain is the most commonly used to diagnose stroke

■ MRI of the brain is more sensitive in acute ischemic infarct

■ the most common cause for hemiplegia is stroke 

■spinal hemiplegia :
•There is ipilateral of loss of deep sensation  and contralateral loss of superficial sensations
• no cranial nerve affect

■ brain stem hemiplegia:
• hemiplegia on the oppsite side
• cranial nerve paralysis of LMN on the same side of lesion 

■Cerebral hemiplegia :
•Hemiplegia + UMNL of 7 and 12 of cranial nerves on the oppiste side of lesion
•Absence of any cranial nerve paralysis on the same side of lesion

🗯 Part 2 :-

■ Meningitis :

○ انا بعمل CT أو MRI عشان بس to exclude SAH
و يعتبر 1st investigation
○ lumbar puncture Is the single most
important investigation and it is the cornerstone of the diagnosis

○Once suspected meningitis should start ttt immedialty even before culture results

○ given Cs before antibiotics in cases of children , TB , streptoccal meningitis

■ cr nr 2 ( ON ) :-

○ parital lobe tumors affect upper fibers of optic radiation
بيعمل  lower  quadrantic contralateral homonymus  hemianopia
○ Temporal lobe tumors affect lower fibers of optic radiation
بيعمل upper quadrantic contralateral homonymus hemianopia

○ Lesion in occiptal lobe :
بيعمل contralateral homonymus hemianopia with preservation of macular vision

■ Cr V nr :
○ central lesion : 
بيحصل lost pain & temperature مع preservation of touch & deep sensations
○ peripheral lesion :
خلي بالك بيحصل sparing the angle of mandible ف sensation

● in trigeminal nr  lesion ( the jaw deviated to the affected side )

● facial nr lesion in UMNL  ( the mouth deviated to the healthy side )

● in hypoglosaal nr lesion ( the tongue deviated to the same side of lesion )

🗯 Part 3 :- 

■ thrombophilia workup is indiacted with unexplained stroke with young < 50yr , hx of thrombosis or clinical suspicion of hypercogulable state

■ CSF analysis :-

● SAH : groosly blood , high ptn , normal
( sugar & CL) , RBCs cells

● meningitis : turbid , high ptn , low
( glucose , CL ) , predominate lymphocyte

● Encephalitis : normal or modest amount of lymphocyte , neutrophil , high Ptn , low
( glucose , CL )

● خلي بالك CRP & ESR عاليين ف meningitis ما عدا ف حالة viral meningitis
● glucose & Cl are low in meningitis except normal with viral

● WBCs > 300/ mm3 except with bacterial meningitis

● thrombolysis with rt-PA should be given with 3-4.5 h & age 18 or older & symptoms suggest ischemic stroke

● rt-PA is CI if BP > ( 185/110mmHg) , within 3 months of brain surgery,  large infarction , INR (> 1.7)

● intra-arterial menchanical thrombectomy is indicated in case of large artery occulsion  in AC circulation
