Fear itself. The amygdala is located in both temporal lobes. One of the chief functions is coordination of perception with fearfulness. Damage to the amygdala can have either stimulatory (fear-enhancing) or inhibitory (fear-negating) effects; either of which can be quite impairing. Other aspects of mood and behavior can be affected. Epilepsy is not infrequently a byproduct of amygdalar damage.
Academic point only. The amygdala is a very small structure. Isolated ischemic damage to just bits of the amygdala never happens and focusing on it is a waste of mental effort. Neurologic deficits caused by the majority of strokes tend to fall into a relatively few clinical syndromes which are worth learning; but you pretty much NEVER see a stroke pt with "just amygdala damage." It just doesn't happen.
