What examination should I do if I often have a headache?

First, routine examination: the most common are three routine examinations of blood, urine and stool, as well as some biochemical and immunological examinations. Routine blood examination can make a simple and intuitive response to headaches caused by different infections, such as the increase of white blood cells and neutrophils, suggesting bacterial infection; If white blood cells are not high or decreased, lymphocytes will increase, suggesting the possibility of virus infection, and hemoglobin will decrease, suggesting the possibility of anemia or blood loss. Routine biochemical examination, such as blood sugar test, can definitely diagnose the headache caused by hypoglycemia.

Cerebrospinal fluid examination: Lumbar puncture examination has unique diagnostic value for head patients. The level of cerebrospinal fluid pressure can distinguish high intracranial pressure from low-pressure headache; Whether cerebrospinal fluid is bloody or not can be immediately judged whether there is cerebral hemorrhage or subarachnoid hemorrhage. Biochemical, cytological and microbiological examination of cerebrospinal fluid can clearly judge whether there is purulent meningitis or nucleated meningitis, or whether there is parasitic infection such as virus and cysticercosis. Immunological examination and cytological examination of cerebrospinal fluid can determine whether there are intracranial cysts or immune lesions.

X-ray examination: the headache caused by pituitary adenoma and intracranial hypertension can be found as soon as possible on the plain film of the head; Sinus radiography can find the headache caused by sinusitis in time, and angiography can find the headache caused by intracranial aneurysm, venous malformation and brain tumor in the early stage.

4. EEG: it is a graph obtained by amplifying and recording the spontaneous biological potential of the brain from the scalp through precise electronic instruments. It can explain the pathological manifestations of local or diffuse headache caused by brain diseases. It also has diagnostic value for headache caused by extracerebral diseases.

5. Intracranial ultrasound examination: measure the echo of the midline of the brain by ultrasound, judge whether the midline structure of the brain is displaced, and diagnose whether there is a space-occupying lesion on the intracranial side. It can assist in the diagnosis of headache caused by cerebral hemorrhage, intracranial tumor, traumatic intracranial hematoma and hydrocephalus.

Radioisotope examination of nervous system: the diagnostic coincidence rate of this method for intracranial tumors is about 80%, which is of unique value for headache caused by intracranial space occupying lesions.

Seven, electromyography: EMG records the electrical activity of nerves and muscles, so as to determine the functional state of nerves and muscles. It has certain clinical value for some headaches caused by nervous headache, trigeminal neuralgia, muscle tension and contraction headache and cervical cone radiculopathy.

Eight, CT diagnosis: For patients with headache, CT has advantages over other auxiliary examinations, which can not only locate intuitively, but also be qualitative. For the diagnosis of various brain tumors, the position, size and outline can be clearly defined. In addition, the diagnosis of cerebrovascular diseases (such as cerebral hemorrhage, subarachnoid hemorrhage, cerebral thrombosis, etc. ) can be made immediately. At the same time, CT can clearly diagnose brain contusion complicated with intracranial hematoma, cerebral cysticercosis, intracranial inflammation and epidural hematoma.

9. Magnetic resonance imaging (MRI) diagnosis: In addition to the same function as CT, it can clearly display three brain structures, which is of unique value for intracranial tumors, spinal cord complications and gray matter degeneration in the brain.

X. positron emission tomography (PET): it can diagnose physiological and biochemical abnormalities of human body.
