What symptom does head oedema have?

summary

Brain edema is a terrible disease in the nervous system. The disease is terrible, but we must have the mentality of conquering the disease. Friends of patients, as long as we firmly believe that the disease can be knocked down, we will not be far away from health. Let's learn about this disease to better overcome it

What symptom does head oedema have?

Increased intracranial pressure makes meninges, blood vessels and cranial nerves stretch and inflammatory changes stimulate nerves and cause headache. It is paroxysmal at the beginning and persistent later. It is mainly on the forehead and bilateral temporal sides. It is often aggravated when coughing, sneezing, defecating, bending or standing up. When brain edema is serious, there may be tearing feeling.

Intracranial hypertension stimulates the vomit center in the base of the fourth ventricle and medulla oblongata to cause jet vomit, which is rarely nauseous and has nothing to do with diet.

The signs of the head, such as swelling and tension of the anterior fontanel, fracture of the cranial suture, enlargement of the head circumference, superficial venous distention of the head and face, and positive broken pot sound, are subacute or chronic compensatory mechanisms, which are related to the incomplete closure of the cranial suture, soft and elastic cranial bone in infants. This compensatory mechanism often makes the early symptoms atypical.

matters needing attention

Because the hypothalamic thermoregulatory center (the front is the cooling center, the rear is the heating center) is compressed, and the heat production increases when the muscle tension increases, and the sympathetic nerve is damaged, the sweat secretion function is weakened, so that the body surface heat dissipation is poor, so the body temperature can rise sharply in a short time, showing persistent, uncontrollable high fever or ultra-high fever. The rectal temperature may be significantly higher than the body surface temperature due to the contraction of peripheral blood vessels. A sharp rise in body temperature is often accompanied by changes in respiration, circulation and muscle tone.
