The differentiation between cervical spondylosis and cerebral infarction includes the following aspects: First, the symptoms of numbness and weakness of the extremities that appear in cervical spondylosis are often manifested as numbness and weakness of both upper limbs or numbness and weakness of the extremities, often accompanied by a feeling of stepping on cotton when walking on the lower limbs. In contrast, numbness and weakness of the extremities in cerebral infarction often manifest as hemiparesis of one side of the limb and sensory impairment, which can be accompanied by symptoms such as slurred speech. Second, cervical spondylosis can cause dizziness, while cerebral infarction can also cause dizziness. Dizziness caused by cervical spondylosis is often due to protruding discs or proliferating bone spurs, which compress blood vessels and lead to insufficient blood supply to the brain, resulting in dizziness symptoms. In contrast, dizziness in cerebral infarction is often caused by insufficient blood supply to the brain due to blockage of cerebral blood vessels, and is not related to the movement of the neck, while elevated blood pressure makes headaches and dizziness more obvious. Therefore, there is a big difference between cervical spondylosis and cerebral infarction in these two aspects, and they need to be differentiated.
