Diagnosis and treatment of idiopathic normal stress hydrocephalus is first recommended today

Hydrocephalus

Hydrocephalus (Hydrocephalus) is not a single disease, hydrocephalus is more common after various head trauma or intracranial masses, so that cerebrospinal fluid absorption disorders, circulatory obstruction or excessive secretion and lead to the ventricular system progressive dilation or (and) subarachnoid dilation, according to pressure can be divided into high cranial pressure hydrocephalus and normal cranial pressure hydrocephalus, according to the cerebrospinal fluid dynamics can be divided into traffic and obstruction

Early CT is manifested by progressive dilation of the ventricular system or (and) subarachnoid dilation

Typical symptoms are headache, weakness of the lower extremities, unsteadiness of starting or gait, urinary incontinence, ataxia, unresponsiveness, and decreased progressive autonomic somatic activity, which can be confirmed

Moderate and severe hydrocephalus is generally enlarged by a CT scan of the ventricles, accompanied by urinary and urinary incontinence, progressive dementia, bed rest, constipation, blurred vision, papilledema, occasionally with diplopia, vertigo, and seizures

Untreated hydrocephalus can also be progressively enlarged by the ventricular system, secondary to brain tissue atrophy and

cerebrospinal fluid

cerebral spinal fluid (CSF) is a colorless transparent liquid filled in the ventricular system, the central canal of the spinal cord and the subarachnoid space, belonging to the non-functional extracellular fluid, containing inorganic ions, glucose and a small amount of protein, very few cells, mainly monocytes and lymphocytes, its function is equivalent to the lymph in peripheral tissues, the central nervous system buffers, protects, nutrition, transport metabolites and maintains normal intracranial pressure

Obstruction and malabsorption of cerebrospinal fluid circulation pathways are usually common, but hypersecretion is rare

Pathological hazards

Obstruction of cerebrospinal fluid circulation pathways, resulting in secondary changes in brain tissue, which manifests as a distillation

If hydrocephalus develops further and the cerebral cortex becomes thinner under compression, cerebral atrophy

Increased intracranial pressure due to hydrocephalus can cause bilateral transverse sinuses to be compressed, impeding blood flow into both internal jugular veins, and thus increased blood return to the modern compensatory extrajugular venous system, secondary scalp venous distension
