Lacunar stroke is caused by the occlusion of some small blood vessels in our skull due to pathological changes in the vessel walls after long-term hypertension, diabetes, or other diseases. Therefore, it usually stems from underlying conditions. Although getting angry may trigger a lacunar stroke, it's important to manage emotions as well. However, for lacunar stroke itself, the primary underlying causes are still hypertension, diabetes, and other risk factors. Thus, regardless of the situation, it's essential to avoid sudden and intense emotional changes, as such changes could potentially trigger a lacunar stroke.
