Dominant, PKD1 or 2 gene
Eventual renal failure
Saccular aneurysm mc occurs where
In anterior circulation, Anterior communicating artery is MC.
What results in worm like arteries and veins?
Ateriovenous Malformation
Is MC cerebrovascular malformation
Who’s most at risk for ateriovenous Malformation (AVM)
Males 2x, MC age 10-30 years old
Headaches in 50% of all cases
What is an occlusion of single artery
Lacunar infarct
It is silent and devastating
When a small cerebral vessel is ruptured and resorbed
Slit Hemorrhage
A “slit like cavity” remains
What occurs when diastolic BP>130 and sever ICP and global cerebral dysfunction
Hypertensive Encephalopathy
This is systemic autoimmune vasculitis, fibrinoid necrosis, small heart and arteries
Polyarteritis Nodosa
What is primary Angiitis of the CNS
chronic inflammation in the multiple parenchyma and subarachnoid vessels
Involves the brain and spinal cord
Who is most at risk for Primary Angiitis of the CNS
Males age 30-60
Injury from aneurysm, hemorrhage, ischemia
Treatment is Immunosuppression
Who is more at risk for CNS trauma
Males 2x more likely
The Assessment is ABCD

Chronic Traumatic Encephalopathy CTE
What is most susceptible during a contusion
Gyri!!!!!!!!!
Coup injury- at impact site
Contrecoup injury- Opposite site of impact
What is it called when movement of one brain region relative to another
Diffuse Axonal Injury (DAI)
Severe dysfunction 50% of causes post traumatic comas
Disrupts white matter, shaking
How long does it take to recover from a Concussion
80% in 10 days without treatment
What is post concussive syndrome
When symptoms last for weeks to months
15-20% of all concussions
Fatigue/low energy= 37% MC
Whats so bad about second impact syndrome
Second concussion can occur and is LETHAL
This is dural ARTERY damage, compresses brain tissue, my be lucid during bleed
Epidural Hematoma
Rapid tear movements of VEIN, subdural bleed, compresses brain
Subdural Hematoma
WHich one has the dura still attached to the skull epidural or subdural
Subdural
What is the most common artery effected by an epidural hematoma
Middle meningeal artery
Very aggressive lethal within hours
What is more common subdural or epidural hematoma
Subdural
