UNDERSTANDING THE BRAIN:
THE NEUROBIOLOGY OF
EVERYDAY LIFE
INTRODUCTION
 This is Derar Aldabek, a neurosurgical resident at Saudi German
Hospital.
 I will be presenting real cases that I myself admitted to our
hospital days and weeks ago.
 I hope they comply with your Neurobiology of Everyday Life.
CASE PRESENTATION 1
 On 19th may 2015 we did an operation for a 55 years old patient who
previously was transferred to our neurosurgery clinic and was complaining of
bitemporal hemianopia (loss of lateral visual field in each eye).
 Magnetic resonance imaging was done and showed a suprasellar mass
pointing to a pituitary macroadenoma.
 We did the operation and we removed the tumor. We only could reach to it
by compressing the FRONTAL LOBE posteriorly (backward).
 After recovery, the patient woke up and started to be severely agitated and
irritable. He was fighting with everyone.
 That was due to frontal lobe edema post compression.
 Conclusion: Partial or complete loss of frontal lobe function might leave the
patient disinhibited and agitated, since the FL is a center of social
disinhibition and the factory of human logic.
CASE PRESENTATION 2
 24 years old male patient presented to emergency department
post road traffic accident. Patient was unconscious, had 3 bouts
of vomiting, AND TWO (2) ATTACKS of CONVULSIONS.
Neurosurgery team was consulted.
 Computed tomography scan (CT scan) was done and revealed
a right precentral (fronto-pariatal) brain contusion. (motor area)
 Conclusion: Lesions affecting the brain’s motor area might lead
to either upper motor neuron diseases, or convulsions.
CASE PRESENTATION 3
 36 years old male patient presented to ER post falling from 2
floors height. Patient was conscious and oriented. On
examination, the patient had quadriplegia.
 CT scan was done and revealed severe 5th cervical vertebra
dislocation that resulted in cord transection at that level. Patient
had some other simple and compound fractures and contusions
spread all over his body.
 Patient still can ventilate himself adequately.
 Conclusion: spinal cord transection at any of the cervical
vertebrae will cause quadriplegia if below c5, and will cause that
in addition to breathing cessation if above c5 level.
THANK YOU
