#Changde Headline##Shimen County People's Hospital#Nerve electrophysiological examination is an extension of nervous system examination. It uses electronic instruments to record the electrical activity of neuromuscles. Through various parameters of electrical activity, it can mak

nystagmus eczema

Application value of nystagmus eczema

Observation of eye movements helps the localization and diagnosis of neurological diseases.

vestibular system is damaged, and a variety of nystagmus can be seen, such as the brain, cerebellar , and brain stem , which will affect the ability of eyeballs to jump, track and coordinate movement.

nystagmus can objectively record eye movements of various amplitudes and speeds when opening and closing your eyes. Used to check

① nystagmus;

② vestibular eye reflex function;

8③ eye movement function.

nystagmus indications:

1, any patient who complains of dizziness and vertigo

2, hearing damage, especially those with low-frequency hearing damage

3, spatial direction disorder (including severe illusions of pilots)

4, suspicious cerebellar lesions

5, skull trauma

6, insufficient blood supply to brain, especially vertebral basal artery blood supply insufficient

7, motion sickness

8, central nervous system dysfunction or suspicious placeholding lesions

9, autonomic nervous system dysfunction

10, eye movement abnormality or suspicious abnormality

electromyography evoked potentiometer

is used to determine the functional status and suspicious lesions of the peripheral neuromuscular system and central nervous system , detect subclinical lesions, and accurately locate the lesions.

The diagnosis and determination of peripheral nerve diseases, myelopathy, demyelination, cervical spondylosis, diabetes , various types of nerve injuries, rehabilitation treatment evaluation, sensory and motor function evaluation, etc.

Indications for electromyography (EMG)

1, various numbness of hands and feet, fatigue

2, neuromuscular junction diseases, myasthenia gravis, etc.;

3, diagnosis of various muscle diseases;

3; 2

4. Various myositis, myositis, such as multiple myositis , muscular dystrophy , dermatomyositis , various drug-derived myositis;

5. Various causes of muscle weakness , muscular atrophy and sensory disorder ; nerve damage to the limbs caused by trauma.

6, also has auxiliary diagnostic value for spinal cord and brain lesions.

Indications for evoked potential examination:

Brainstem auditory evoked potential (BAEP):

1, brainstem lesions;

2, multiple sclerosis;

3, posterior fossa tumor;

4, insufficient blood supply to the vertebral basal artery;

5, dizziness;

6, brain death monitoring.

Checkerboard visual evoked potential (PR-VEP):

1, neuropathy;

2, multiple sclerosis;

3, glaucoma;

4, brain tumor;

5, cerebral infarction ;

6, objective determination of visual function

EEG

EEG is a functional examination of the cerebral cortex, non-traumatic, simple and economical. It has diagnostic or auxiliary diagnostic value for neurological diseases, and plays an important role in the diagnosis of epilepsy.

EEG examination indications:

1. Epilepsy: Determine whether the seizure event is epilepsy seizure ; determine the type of epilepsy; determine the possible epilepsy syndrome; help discover the triggering factors of epilepsy.

2, central nervous system infection ;

3, intracranial placeholder lesions ;

4, cranial brain injury ;

5, Intelligent disorder caused by various reasons, consciousness disorder , children's tics, ADHD, carbon monoxide poisoning, alcohol poisoning, hypoxic ischemic encephalopathy, etc.;

6, genetic metabolic diseases;

7, brain dysfunction caused by other reasons.

8, Brain death monitoring.

Precautions for EEG examination:

1. Wash your hair the day before the examination and do not use oil

2. Stop using sedatives, stimulants and other drugs that act on the nervous system 24 hours before the examination

3. The examination should be performed within 3 hours after the meal

4. The whole body should be relaxed during the examination to avoid excessive tension and interference

5. During the monitoring process, do open eyes and excessive ventilation

6. During the monitoring process, make detailed records according to the doctor's requirements.

Transcranial Doppler (TCD)

Transcranial Doppler is a detection of the stenosis, occlusion and collateral circulation of the large blood vessels in the cranial through the temporal window, occipital window and eye window of the skull. It can also monitor the occurrence and disappearance of cerebral artery spasm under dynamic conditions, which has a large reference basis for the diagnosis of cerebral vascular diseases.

adapted to the population:
1. Screening for cerebral artery stenosis in various populations.

2, high-risk groups such as hypertension, , diabetes, hyperlipidemia, smoking, alcoholism, advanced age and overweight. Patients with suspected intracranial vascular lesions such as

3, trauma, intracranial infection, migraine , cervical spondylosis, subarachnoid hemorrhage, and other suspected intracranial vascular lesions.

4, patients with headache, dizziness, vertigo, fainting, numbness and weakness on one side of the limb, transient blackness and other patients with cerebrovascular symptoms.

5, transient cerebral ischemic attacks , cerebral infarction , and cerebral infarction , and cerebral infarction .

6, patients with traumatic or non-traumatic ischemic cerebral edema and suspected intracranial placeholder lesions.
