Neurology is a large department that contains many kinds of diseases. Due to the special nature of neurology, patients often cannot distinguish neurological diseases from other departments, so they do not know what department to register and delay the treatment. Facial palsy: the common cold or wind after the emergence of one side of the mouth crooked, can not close the eyes, tears, can not drum cheeks and teeth, etc., just found when there may be only minor symptoms, the emergence of one side of the corner of the mouth weak, often ignored, delaying early treatment, this disease in the acute phase of treatment is the best effect, the longer the effect is worse, so remind everyone, if the above symptoms should come to the clinic in a timely manner, so as not to delay the disease. Cerebral infarction: cerebrovascular disease is the top three diseases in China in terms of incidence, but the early symptoms are still ignored by everyone, and the early treatment of cerebral infarction is very critical and directly affects the prognosis of patients, so we must know some of the early symptoms of cerebral infarction to achieve early detection, early treatment and improve the prognosis. Early symptoms of cerebral infarction include: numbness or weakness of one limb, or numbness or weakness of only one upper or lower limb, facial palsy, slurred speech, salivation at the corners of the mouth, difficulty in swallowing, unstable walking, falling, diplopia, dizziness, blurring of objects, etc. The above symptoms can appear more than one at the same time or only one, when these symptoms appear, you should seek medical consultation in time, and it is likely that cerebral infarction has occurred. TIA: transient ischemic attack is a series of symptoms caused by transient ischemia in the brain, which usually lasts for a short period of time, from a few seconds to an hour, and sometimes lasts for several hours, and symptoms similar to cerebral infarction can appear during the attack, but they are quickly relieved. Therefore, early treatment can prevent further development of the disease.
