Dizziness with dizziness

Introduction Dizziness, also known as dizziness, is a subjective sensory abnormality. Can be divided into two categories: one is rotatory vertigo, mostly caused by vestibular nervous system and cerebellar dysfunction, mainly to 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. Dizziness is a manifestation of multiple organs in the body or overall neurological dysfunction. Once dizziness occurs, it should actively seek the cause and actively treat it.

Cause

The cause of dizziness, which is mainly dizziness, is caused by certain systemic diseases. There are severe arrhythmia, diabetes, hypotension, or high blood pressure, CO poisoning, hypoglycemia, severe anemia, etc., and mental stress, fatigue, allergies, endocrine disorders, infections, etc., may have basilar arteriosclerosis. Cervical spondylosis, cerebellar lesions, intracranial trauma, acoustic neuroma, temporary cerebral insufficiency.

Dizziness-based dizziness examination: the main feeling of dizziness, feeling top-heavy. The examination of dizziness mainly includes examination of vital signs, such as blood pressure level, blood sugar level, and whether there is infection, whether there is fever, and whether the head is actively examined for lesions, such as cerebral hemorrhage, head occupying, etc. Feasible head CT examination.

Differential diagnosis

Dizziness-like dizziness is easily confused:

Not biased to one side, no vertigo: There is a kind of dizziness, only dizziness, top-heavy, but also unstable, even falling, but not biased to one side, no clear surrounding environment or the sense of movement of its own rotation, nor There is nystagmus, called pseudo vertigo, or non-systemic vertigo.

The main symptom of benign paroxysmal positional vertigo is that you will feel dizzy or tilted and you are not turning or tilting. It happens when you move your head at a certain speed, such as flipping on a bed, turning your head quickly, bending over quickly, and quickly returning your head. Benign paroxysmal orthostatic vertigo often lasts for 1-2 minutes. It can be mild or severe, making you feel uncomfortable in the stomach and vomiting. Sometimes I find it difficult to stand or walk and lose balance.

Symptoms of orthostatic vertigo: The cervical vertebrae, thoracic vertebrae, 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.

Visual recognition disorder vertigo is a symptom of toxic vertigo. The patient often walks with a head straight and walks straight ahead, called visual recognition disorder vertigo.

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. Dizziness is a general term for dizziness and dizziness. It is glare with vertigo, unclear vision and darkness and darkness. It can be rotated by the object, or can not stand as a halo.

Rotational vertigo is caused by dysfunction of the vestibular nervous system and cerebellum. It is mainly caused by the feeling of dumping, and it feels its own shaking or the rotation of the scene.

Cervical vertigo: refers to the qualitative or functional changes in the cervical vertebrae and related soft tissues (joint capsules, ligaments, nerves, blood vessels, muscles, etc.). During the examination, the frontal spinous process, the interspinous process, the transverse process, the paraspinal muscles, the lower part of the occipital trochanter, and the upper scapular area were tender, tense, hard or indurated. Even when the patient presses a certain part overnight, there may be dizziness and nystagmus or vertigo in the cervical vertebrae, and the head and neck movements are limited.
