Numbness of the hand caused by hypertension should first be considered to be related to cerebrovascular disease, and cervical spondylosis cannot be ruled out. Patients should first clarify the cause of the numbness. If they have suffered from hypertension for a long time and develop numbness in the hands, along with dizziness and discomfort, a head examination, such as MRI or CT, should be performed to clarify whether there are cerebrovascular problems or brain parenchymal problems. Transient cerebral ischemia, also known as mini-stroke, occurs in some hypertensive patients before they have a cerebrovascular accident. Sometimes it is a temporary cerebral ischemia that will pass in a few minutes, signaling that a more serious stroke may occur. Typical symptoms of transient cerebral ischemia include abnormal states of sensation in the limbs such as numbness in the hands and feet, as well as transient blurred vision, headache, and dizziness. Therefore, hypertensive patients with numbness in the hands should pay high attention to it. In addition, hypertension combined with diabetes mellitus, peripheral neuropathy or cervical spondylosis may also cause numbness in the hands, and corresponding examination and treatment should be given in this case.
