Rotational vertigo

Introduction Dizziness, also known as dizziness, is a subjective sensory abnormality. Can be divided into two categories: One is rotatory vertigo, mostly caused by the vestibular nervous system and cerebellar dysfunction, mainly based on the feeling of dumping, feeling their own shaking or scene rotation. The second is general halo, which is caused by some systemic diseases. It is mainly caused by dizziness and feels top-heavy. Peripheral vertigo: refers to vertigo caused by lesions in the inner ear or vestibular nerve. Common in Meniere's disease, labyrinthitis, drug vertigo (caused by streptomycin or gentamicin and other drugs) and vestibular neuritis.

Cause

Causes of rotatory vertigo:

Rotational vertigo can be divided into two types: peripheral vertigo and central vertigo.

(1) Peripheral vertigo: refers to vertigo caused by lesions of the inner ear or vestibular nerve. Common in Meniere's disease labyrinthitis, drug vertigo (caused by streptomycin or gentamicin and other drugs) and vestibular neuritis.

(2) Central vertigo: refers to vertigo caused by brain stem, cerebellum, brain and spinal cord lesions. Common in vertebral-basal artery insufficiency, intracranial tumors, intracranial infection, multiple sclerosis, vertigo epilepsy and traumatic vertigo.

an examination:

After the initial cause judgment, the corresponding physical examination and laboratory examination are carried out. The physical examination focuses on vestibular function, hearing, neurological examination and cardiovascular system examination.

Differential diagnosis

Symmetrical symptoms of rotatory vertigo:

Transient vertigo: Benign paroxysmal orthostatic vertigo is caused by problems with the inner ear, which can cause transient vertigo attacks. Dizziness is the feeling that you are spinning or that things around you are spinning. For some people, benign paroxysmal orthostatic vertigo will resolve on its own within a few weeks, but it will recur again, it is not a serious illness.

Postural vertigo: vertigo caused by changes in the position of the vertical axis range, which is postural vertigo. Some longitudinal vertigo is vertigo at a certain height during waking or lying down, and is also a positional vertigo. The cervical, thoracic and caudal vertebrae are a longitudinal axis of the body. The change in the position of the longitudinal axis. For example, getting up, lying down, turning over can cause dizziness.

Otogenic vertigo: refers to vertigo caused by abnormal vestibular vagus. When there is lost water (Ménière syndrome), motion sickness (sickness sickness), labyrinthitis, labyrinthine bleeding or poisoning, vestibular neuritis or damage, middle ear infections, etc. can cause postural balance disorders, vertigo. Because the vestibular nucleus is closely related to the nucleus of the oculomotor through the medial bundle, nystagmus often occurs when the current court is stimulated by pathology.

Eye-induced vertigo: non-motor illusion vertigo, mainly manifested as instability, increased when the eye is excessive, and relieved after closed eyes. Dizziness lasts for a short period of time. When you look at the moving objects, you will get worse. After you close your eyes, you will ease or disappear. Often accompanied by blurred vision, decreased vision or double vision. Visual acuity, fundus, and eye muscle function tests are often abnormal, and the nervous system has no abnormalities.

Senile vertigo: usually manifested as dizziness, balance disorder and imbalance. When the patient blinks, he feels his own rotation and shaking, just like a car. Can not stand at the time of onset, accompanied by nausea, vomiting, tinnitus, sweating, bradycardia and decreased blood pressure and other symptoms of increased vagal tone, usually lasting for several minutes to several hours, sometimes up to several days, the vestibular system, visual system and location of the inner ear When the proprioceptor of the joint is transmitted into position and the signal of the vestibular ganglion is asymmetric, the control center located in the cerebellum and cerebral cortex can cause dizziness. Central vertigo can often occur ataxia, according to the symptoms can be judged at the site of the disease: corticospinal tract damage, can cause limb weakness or complete paralysis of the limbs and Babinsky sign positive, accompanied by rigidity and folding knife Sample.

Paroxysmal vertigo: is a common mechanical condition of the inner ear, accounting for about 20% of all vertigo, and is also the cause of about half of otogenic vertigo. Although the disease is an ear disease, it is often diagnosed in the first diagnosis of neurology, and many misdiagnosed as vertebrobasilar insufficiency, cervical vertigo and delayed treatment.
