Good "textbook" answer, however in practice motor weakness may occur in
addition to the classical cerebellar signs of intention tremor, disturbed fine
motor control, slurred speech, and nystagmus. Weakness and flaccidity may
occur even when the damage is limited to the cerebellum, though traditional
texts don't describe this. (I promise I'm not making this up - I have seen
such cases personally.)

I would also point out that a "bad stroke" anywhere in the brain (e.g. a
significant haemorrhage) could cause death due to mass effect.
