Cerebral effusion refers to the excessive accumulation of cerebrospinal fluid in the skull due to excessive cerebrospinal fluid secretion, circulatory obstruction or absorption obstruction caused by various reasons. According to the cerebrospinal fluid circulation dynamics, cerebral effusion can be divided into obstructive cerebral effusion and traffic cerebral effusion. Traffic cerebral effusion usually refers to cerebral effusion obstruction site is outside the ventricular system, mainly due to the cerebral convexity or the base of the skull arachnoid membrane adhesion, intracranial venous reflux obstruction and so on caused by cerebrospinal fluid absorption obstruction, and caused by cerebral effusion. Obstructive hydrocephalus is a pathological phenomenon caused by obstruction of the cerebrospinal fluid circulation pathway above the fourth ventricle due to congenital or acquired factors, resulting in obstruction of cerebrospinal fluid flow into the subarachnoid space (or cerebellar medullary pool).

The clinical manifestations of patients with traffic hydrocephalus are related to age, intracranial pressure, and the urgency of onset of the disease, and may include headache, nausea and vomiting, incontinence, and cognitive impairment. Obstructive hydrocephalus its clinical manifestations in young children with large head, 'sunset sign', vomiting, visual impairment, difficulty in sucking and feeding, inward slanting of the eyes, laryngeal tinnitus, head drooping, weakness or spastic paralysis of the limbs, intellectual developmental disorders, and even convulsions and lethargy. In adults, it manifests as intermittent headache, head swelling, head sinking, dizziness, tinnitus and ear blockage, vision loss, lower limb weakness and other symptoms. Acute cerebral effusion, in addition to the manifestation of primary injury, there is a progressive increase in intracranial pressure and progressive aggravation of impaired consciousness; although surgical removal of hematoma, thwarting of inactivated brain tissues and dehydration and other treatments, the consciousness is once improved and then deepened.

I hope the above answer can help you.

　　This question is answered by Sanbo Brain Hospital of Capital Medical University, and we look forward to your attention~

　　Song Ming, director of Sanbo Brain Hospital of Capital Medical University, said that the clinical features of hydrocephalus are affected by the patient's age, etiology, location of obstruction, duration and speed of onset. Symptoms in infants include poor feeding, irritability, decreased activity and vomiting.

　　Symptoms in children include: (1) delayed intellectual development; (2) headache (starting early in the morning) more pronounced than in infants, due to the healed skull sutures; (3) neck pain, suggestive of herniation of the cerebellar tonsils; (4) vomiting, more pronounced in the morning; (5) blurred vision: a consequence of optic disk edema and secondary optic nerve atrophy; (6) diplopia: associated with unilateral or bilateral abducens palsy; (7) developmental disorders associated with enlargement of the third ventricle and delayed sexual maturity: this can lead to obesity and early maturation or delayed puberty; (8) difficulty in walking secondary to spasticity: due to hydrocephalus that causes periventricular delays in puberty; and (9) difficulty in walking due to spasticity: due to hydrocephalus that can lead to obesity and early maturation or delayed puberty. Developmental disorders and delayed sexual maturation associated with enlargement of the third ventricle: this can lead to obesity and early maturation or delayed puberty; (8) difficulty in walking secondary to spasticity: due to hydrocephalus stretching the periventricular pyramidal tracts, the lower limbs are first involved; (9) lethargy.

　　Symptoms in adults include: (1) cognitive decline: can be confused with other types of dementia in older adults; (2) headache: more pronounced in the morning and relieved by standing because of less efficient reabsorption of CSF in the prone position; headache worsens and becomes persistent as the disease progresses; (3) neck pain: if present, it may be indicative of a cerebellar tonsillar protrusion of the greater occipital solenoid; (4) nausea: It is not aggravated by movement of the head; (5) vomiting: sometimes explosive, more pronounced in the morning; (6) blurred vision (transient grayness): may indicate severe optic nerve involvement, which needs to be treated as an emergency; (7) diplopia: caused by abducens nerve paralysis; (8) difficulty in walking; (9) lethargy; (10) urinary and fecal incontinence: suggestive of significant frontal lobe destruction and progressive disease.

Symptoms of hydrocephalus are dominated by the manifestations of increased intracranial pressure, and the clinical manifestations can differ between children and adults, as follows:

1. Hydrocephalus in children can produce a huge head, difficulty in upward vision, and impaired intellectual development, in addition to the symptoms of increased intracranial pressure itself, such as headache, nausea, vomiting, blurred vision, and unsteady walking;

2. The occurrence of hydrocephalus in adult patients is often considered by patients as a manifestation of their own aging due to its more insidious symptoms and slower development. Normal clinical symptoms of pressure hydrocephalus are unsteady gait, progressive intellectual decline and urinary incontinence. If the above symptoms appear clinically, it is necessary to go to the hospital to exclude the possibility of hydrocephalus.

Hydrocephalus is caused by the obstruction of cerebrospinal fluid circulation in the brain, and it has some symptoms, including those of adults and children. The symptom that occurs in all people is headache, which is chronic and aggravated by sneezing and coughing. Then there is vision loss, because hydrocephalus is often combined with cranial hypertension, which can compress the optic nerve and produce optic nerve atrophy and affect visual impairment. In addition, cranial hypertension can also produce nausea and vomiting, especially during exercise and positional changes. In addition, progressive gait disorders, such as unsteady walking, slow walking, and difficulty in lifting the legs, can occur. Hydrocephalus can also result in incontinence, retention of urine and feces, and in severe cases, dementia, a symptom common to all hydrocephalus. For children, because the skull of children is not fully developed, after hydrocephalus, due to cranial hypertension, the child may have widening of the gap between the sulcus and the fissure of the brain, turning into a big-headed doll, and after hydrocephalus, the patient's brain function development will be delayed, resulting in the child's intellectual, motor, sensory, and comprehensive ability to be retarded, retardation, and this is the main symptom of hydrocephalus.

The face and scalp are bright and shiny, and tapping the brain with a knock makes a sound like a broken sand jar! From time to time there is also a clear runny nose!

Hydrocephalus in children can produce a huge head, difficulty with upward vision, and impaired mental development

　　Dizziness, headache and vomiting As hydrocephalus compresses the nerve tissues, the affected children will experience discomfort, which is more common as intermittent dizziness, headache and vomiting. Long-term development will have serious impact on the health of the children.

Blurred vision and double vision The appearance of this symptom mainly indicates that the optic nerve of the child has been compressed and infested, and if not treated in time, it will have a more serious impact on the child's vision.

Third, enlarged skull, vertigo with epilepsy The most visual symptom of hydrocephalus in children is the enlarged skull, accompanied by complications such as vertigo and epilepsy. Accumulated cerebrospinal fluid can cause pressure on the child's brain tissue, causing it to become diseased.

The symptoms are different for each person.

What are the symptoms of common hydrocephalus:

Symptoms of hydrocephalus can be divided into infantile hydrocephalus, adult hydrocephalus, and hydrocephalus in the elderly. Infantile hydrocephalus is generally characterized by vomiting, increased fontanel pressure, and sunset sign, and then mainly there are patients with increased head circumference, which we call big-headed dolls; adult hydrocephalus can also be characterized by intracranial hypertension, which can have a wide range of symptoms, such as vomiting, headache, and some of them can affect the central functions. Intracranial hypertension manifests itself in vomiting, headache, and even in some cases affects other central functions, such as unsteady walking. Geriatric hydrocephalus is mainly associated with poor bowel control, especially poor urinary control, unsteady walking, and in some cases, dementia, which means loss of memory and poor mental ability, is present.

Specifically, this can be illustrated by the following scenarios

What are the early symptoms of mild hydrocephalus:

What is the cause of hydrocephalus in infants? The first one we are not talking about is called congenital hydrocephalus, and the second one is called acquired hydrocephalus. Congenital hydrocephalus and acquired hydrocephalus, also divided into whether it's caused by infection, or whether it's caused by a tumor, or whether it's caused by some intracranial malformation, so it's different. We now see a lot of acquired hydrocephalus, especially in late infancy, which is mainly caused by infection. Because our children's developmental function is incomplete, the immune function is incomplete, so it is easy to get infected, meningitis, pneumonia, all easy to cause hydrocephalus, this kind of hydrocephalus we are more acquired, but it is more common.

What are the symptoms of severe hydrocephalus:

What are the symptoms of severe hydrocephalus and again there are two types. Severe What do you mean by severe, is the severity of the hydrocephalus enlargement. It may be that this is what is meant, this is the severe hydrocephalus, generally speaking, is the baby that time hydrocephalus left behind untreated. His parents were not willing to treat or the doctor was not willing to give treatment for fear of complications, it has continued until it has been able to hold on. At this time, his symptoms themselves are generally not walking too steadily, some intelligence is not very good or head is a little big. Anyway, he basically can't blend in with the normal population, and these are his symptoms. Some aggravation, he further aggravation and blockage, further aggravation will be cranial hypertension, cranial hypertension will headache, vomiting may coma.

What are the symptoms of hydrocephalus after brain tumor surgery:

After brain tumor surgery, hydrocephalus is present as well as a symptom of cranial hypertension. In some cases, dysfunction occurs, as in the case of tumors within the ventricles of the four cerebral chambers. Often we have motor mutism syndrome (motor inability mutism) after medulloblastoma removal. Instead of talking, biting or pinching, we can sometimes get early relief after early surgery. In some cases, there is high cranial pressure, which means vomiting, inability to eat, or the like. Our limb movement is not good, in which part of the pressure of which place, exactly the pressure of the limb it can not move the shunt it out, his limb movement will be good.

What are the symptoms of obstructive hydrocephalus:

In fact, it is not called obstructive, we call obstructive hydrocephalus, some people divide hydrocephalus into traffic hydrocephalus, and obstructive hydrocephalus two kinds. Obstructive hydrocephalus, many people think it is caused by tumor, and many people say it is called aqueduct obstruction, so the hydrocephalus enlarges on the curtain, and it is called obstructive hydrocephalus. Nowadays, especially in infants, I think it's a little bit too broad of an application to say obstructive hydrocephalus. We can now say that any endoscopic, failed third ventriculostomy, unsuccessful first time, no ventricular reduction, no cranial reduction, it's not considered obstructive hydrocephalus. It's traffic hydrocephalus because if it's obstructive hydrocephalus, it's going to be cured, and it's not cured, it's not obstructive hydrocephalus.
