What is the aftermath of stroke?

Loss of function: A stroke involves a loss of blood flow to an area in the brain or less commonly bleeding into the brain. The specific aftermath depends of what part of the brain is affected and the amount of the damage. The ultimate outcomes can vary widely, from very severe, such as inability to speak, paralysis and even death, to mild, for example weakness of an arm or leg that completely resolves with time.

Stroke: The 'aftermath' of stroke depends on the type and location of the stroke.....I.E. Infarct or hemorrhage, lacunar (very small) or watershed (large), arterial or venous, cortical or subcortical. The question as you put it is too general to be able to answer generically. The consequences may be from minimal or nil to death, depending on the details.
