How does dizziness return a responsibility when sleeping?
summary
Many people get up in the morning after dizziness, nausea, and even fainting situation, diet should also pay special attention to, often dizziness, sometimes accompanied by nausea, vomiting, and in getting up or turn more prone to occur. So, let's take a look at the dizziness when sleeping? Let's introduce the related knowledge of the field.
How does dizziness return a responsibility when sleeping?
The first is non vestibular systemic vertigo. 1. Dizziness before syncope is called aural syncope. The mechanism of this symptom is the decrease of whole brain blood flow, including vagus reflex and orthostatic hypotension, which leads to the decrease of whole body blood pressure. ② Arrhythmia, cardiomyopathy or valvular heart disease can lead to cardiac aural syncope. ③ Hypoglycemia in diabetic patients treated with insulin or sulfonylurea may lead to tremor, palpitation, fatigue and threatened syncope. ④ Hyperventilation is a common cause of vertigo in young patients with anxiety or panic disorder. These patients complained of numbness and tingling in the perioral or bilateral fingers. Nausea and sweating, blurred vision, and pale skin may be associated with the previously mentioned aural syncope events. ⑤ A variety of drug reactions can cause vertigo, whether it is direct ototoxicity (aminoglycosides) or cerebellar injury (phenytoin, promethidone, ethanol). In addition, the feeling of turbidity or dizziness caused by sedative drugs may be interpreted by patients as vertigo.
Second, unilateral vestibular dysfunction can aggravate the symptoms of acute vertigo, such as strong sense of rotation, which may originate from peripheral lesions (labyrinthine or vestibular neuropathy) or central lesions (such as brainstem or cerebellar vestibular system lesions). Patients often have nausea, vomiting, pale and fatigue symptoms, accompanied by walking difficulties, and spontaneous nystagmus.
Third: central vertigo: ① elderly patients with history of hypertension, hypercholesterolemia and cardiovascular and cerebrovascular diseases may have central vertigo. Hearing loss is rare, and paralysis is the prominent manifestation. When the patient looks away from the lesion side, nystagmus occurs first. Brain CT or MRI should be performed as soon as possible to exclude infarction or hemorrhage in cerebellum or brain stem. The treatment should focus on the pathophysiological changes, antiplatelet or anticoagulant therapy. Brain stem decompression is necessary for acute cerebellar hemorrhage. The recovery of central vestibular system injury takes days to weeks. ② Young patients with multiple sclerosis (MS) may develop central vertigo (5% of MS cases). MRI can show multifocal white matter T2 or fluid attenuated inversion recovery (FLAIR) lesions.
matters needing attention
Many cases have symptoms without obvious inducement, and some cases are caused by brain injury. Vascular lesions in the inner ear are predisposing factors in older people. Symptoms usually subside within a few months, but recur. 50% of the cases can not find the specific cause.
