Elderly people who experience a cerebral infarction (stroke) may show several typical symptoms if the condition worsens. Firstly, their speech may suddenly become unclear, accompanied by a slight drooping of the mouth and drooling. Another symptom is difficulty in extending the tongue straight out, as it may not align centrally. Additionally, there may be weakness in the limbs. These symptoms indicate the presence of a new cerebral infarction lesion. In such cases, it is crucial to promptly go to the hospital for a head CT scan or an MRI to determine whether the scope of the stroke has expanded or if a new stroke has occurred.
