Introduction

Introduction Severe dizziness and unstable standing are the main manifestations of cerebellar lesions. Due to insufficient blood supply to the brain, the patient may suddenly have dizziness, and there are symptoms of visual impairment, weakness of the limbs, and instability of standing, which occur when the neck activity is large.

Cause

Cause

Due to insufficient blood supply to the brain, the patient may suddenly have dizziness, and there are symptoms of visual impairment, weakness of the limbs, and instability of standing, which occur when the neck activity is large.

an examination

Cerebrospinal fluid protein qualitative (CSF.Pro) cranial CT examination

Positioning diagnosis

According to the patient's symptoms and signs, the lesions were analyzed. The lesions in the cerebral hemisphere showed lateral paralysis, tongue palsy, limb hemiplegia and hemianopia; cerebellar lesions mainly showed severe dizziness, unstable standing, nystagmus, etc.; For example, if the cross is paralyzed, the lesion is oblique to the side of the mouth, the tongue is skewed, and the contralateral limb is hemiplegic and the feeling is reduced.

2. Qualitative diagnosis

According to the pathogenesis, the characteristics of the disease and the lesions, the nature of the disease is analyzed, and it is judged to be hemorrhagic or ischemic cerebrovascular disease. The principles of treatment are different. CT or MRI can confirm the location and nature of the lesion.

According to the whole process of the disease, combined with localization and qualitative diagnosis, find out the specific cause of the disease.

Diagnosis

Differential diagnosis

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.

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.

Rotational vertigo: 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 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.

Positioning diagnosis

According to the patient's symptoms and signs, the lesions were analyzed. The lesions in the cerebral hemisphere showed lateral paralysis, tongue palsy, limb hemiplegia and hemianopia; cerebellar lesions mainly showed severe dizziness, unstable standing, nystagmus, etc.; Such as cross-sexual paralysis, the lesion is oblique to the side of the mouth, the tongue is skewed, the contralateral limbs are hemiplegia, and the feeling is diminished.
