What are the early symptoms of cerebral infarction? What is cerebral infarction?

Cerebral infarction refers to a disease in which local brain tissue necrosis or softening occurs due to ischemia and hypoxia caused by impaired blood supply to the brain. Cerebral infarction poses a great threat to humans, so what are the early symptoms of cerebral infarction?

Sudden dizziness

Suddenly feel dizzy, unsteady on your feet, or even faint, or fall suddenly for unknown reasons. This is due to insufficient blood supply to the vertebral basilar artery, which affects the balanced neural tissues such as the cerebellum and brainstem.

Limb numbness

Sudden numbness and weakness in one limb, or numbness in one side of the face, hands, feet, tongue, or lips, or crooked mouth, drooling, or limited movement of the upper and lower limbs. This is caused by insufficient blood supply to the contralateral internal carotid artery, affecting the anterior-posterior blood flow back to the central cerebral cortex.

Sudden slurred speech

Sudden slurred speech or even inability to speak but able to understand what others say, or being able to speak but unable to understand what others say, is medically known as motor aphasia or sensory aphasia. This is caused by insufficient blood supply to the cerebral arteries, which affects the language center of the cerebral cortex.

Feeling drowsy all day

The patient suddenly becomes drowsy and sleepy all day long, unable to control himself, and is in a state of drowsiness. This is due to insufficient blood supply to the vertebral basilar artery, which affects the reticular structure of the brainstem.

Personality and mood changes

Sudden changes in personality, thinking, intelligence, and behavior, such as becoming depressed, silent, withdrawn, indifferent, or becoming furious, euphoric, irritable, talkative, or experiencing a temporary loss of consciousness or intellectual decline, or even loss of normal comprehension and judgment. This is mainly due to insufficient blood supply to the internal carotid artery system, which damages the function of the frontal lobe of the brain.

Visual abnormalities

Sudden onset of short-term blurred vision, blackness, and monocular blindness that lasts for a few minutes, followed by recovery of vision, is due to insufficient blood supply to the ipsilateral artery or the ipsilateral ophthalmic artery.
