What tests should be done to examine the brain?

The brain is an important nervous system of the human body. It controls all daily activities of the human body, including human consciousness and many movements of behavior. If there is a problem with the brain, it will have a serious impact on human health. However, the brain is very complex. If the brain is damaged, it is necessary to find out the cause in time so that targeted treatment can be given. So what kind of examination should be done to check the brain?

What tests are done to check the cranial nerves?

Depending on the condition, different examination items need to be selected:

Lumbar puncture and cerebrospinal fluid examination.

Imaging examinations included skull and spine X-rays, digital subtraction angiography, computed tomography, and magnetic resonance imaging.

Neurophysiological examinations included electroencephalography, magnetoencephalography, evoked potentials, electromyography, and nerve conduction velocity.

Ultrasound examination of head and neck vessels includes carotid artery ultrasound and transcranial Doppler ultrasound.

Radionuclide examinations include single photoelectron emission computed tomography and positron emission tomography.

Brain, nerve, and muscle biopsies include brain biopsy, nerve biopsy, and muscle biopsy.

Examination of the cranial nerves

There are many items in cranial nerve examination, only a few are listed here:

1. Olfactory nerve examination: The sensitivity of the sense of smell can be understood through questioning.

2. Visual field examination: Visual field refers to the range that the patient can see when looking straight ahead without moving his eyes.

3. Trigeminal nerve examination (trigeminal examination) The trigeminal nerve has both motor and sensory functions. The examination includes facial sensation, motor function, corneal reflex and jaw reflex.

4. Facial nerve examination includes two parts: movement and taste examination.

5. Auditory nerve examination includes hearing test and vestibular function test, which is used to determine whether there are lesions in the cochlear and vestibular nerves.

Cranial nerve examination has very important clinical significance and plays an important role in doctors' judgment of patients' conditions. If the patient has problems with brain nerves, he must actively cooperate with treatment. If the disease is delayed, the damage to the body will be irreparable.

What are the symptoms of neurasthenia

1. The most obvious symptom of neurasthenia patients is insomnia. They cannot sleep all night long. During the day, they feel dizzy, uncomfortable all over, and have back pain. These symptoms must be taken seriously. They should go to the hospital for relevant examinations and take some medications. Neurasthenia should not be delayed for too long to avoid aggravating the patient's symptoms.

2. Neurasthenia patients are often emotionally unstable, easily nervous, and experience soreness in the limbs. This symptom of body pain has nothing to do with whether they are overworked. Even if they rest for a period of time, the symptoms cannot be relieved. Neurasthenia patients can be treated through traditional Chinese medicine. Massage can also help treat neurasthenia.

3. After suffering from neurasthenia, you will also suffer from inattention, memory loss, etc. You will become more and more lazy at work and study. When you want to remember some problems, you always forget them easily. Sometimes you will even have symptoms of chest tightness, shortness of breath, and gastrointestinal discomfort.
