It is simply called ischemic stroke.
If a blood vessel ruptured and caused insufficient blood supply to the brain, it would be called hemorrhagic stroke.
If a clot of some kind caused the insufficiency, it would be called thromboembolic stroke.

well - with insufficient blood to your brain
Decreased Perfusion Pressure
PP = MAP - ICP
and you've decreased the MAP.
... and yes, shock can be one cause of this. But so can transient conditions such as arrhythmia or vaso vagal syncope, orthostatic hypotension ... etc.
So you get a "faint" or "unconscious collapse". Also known as "syncope"
If the brain is deprived of blood supply for sufficient time, the nervous tissue will be irretrievably injured and yes, this can result in a "stroke" (cerebral infarction)

Cerebral hypoperfusion covers it all.
As mentioned this can be due to a number of factors from poor cardiac output (insufficient rate, insufficient stroke volume, insufficient intravascular volume, to insufficient vascular tone), or poor flow into the cerebrum (i.e. plaque riddled carotids) or higher than normal intracerebral pressure ICP (see aforementioned calculation).
The extent (severity and length) of hypoperfusion can lead to other medical conditions from a simple lightheadedness to a short period of unconsciousness (syncopal episode), to reversible ischemia (TIA or misnamed "ministoke"), to irreversible infarction (CVA or stoke), to diffuse axonal damage, to overwhelming brain death.
Sometimes this is done intentionally such as during a carotid endarterectomy where the carotid artery is clamped so we can operate on it (granted there is usually adequate collateral flow through the contralateral carotid and vertebrals).
