Mr. Wang, a 34-year-old programmer, led an unhealthy lifestyle with long hours of work, lack of sleep, and a diet rich in fried and high-sugar foods, leading to obesity. One morning, his colleague noticed that he had a slight facial droop and recommended that he visit a hospital. After a brain MRI, it was revealed that he had suffered an acute ischemic stroke. Fortunately, it was a lacunar stroke, and he was discharged after a few days.

Facial Droop (Peripheral and Central): When a blood clot forms in the brain, it can cause facial droop. Peripheral facial droop is mainly related to viral infections or compression of the facial nerve. It is characterized by disappearing forehead lines, incomplete eye closure, crooked mouth angle, and speech difficulties.

Central facial droop, on the other hand, is related to the formation of a blood clot and is characterized by crooked mouth angle, shallow nasolabial groove, and deviation of the tongue. 

Numbness of the Face: When brain cells experience ischemic necrosis, the transmission of sensory nerves to the face and limbs is hindered, leading to numbness in the lower half of the face.
