For hydrocephalus, it often manifests as noticeable enlargement of the ventricular system. Additionally, patients experience symptoms of increased intracranial pressure such as headaches, dizziness, nausea, and dry heaves. Severe hydrocephalus can lead to significant increases in intracranial pressure, with patients suffering from severe headaches, dizziness, and even accompanied by papilledema, decreased vision, visual field defects, and optic atrophy. Furthermore, patients with hydrocephalus may exhibit significant cognitive dysfunction, characterized by reduced intelligence levels, diminished learning ability, computational skills, and memory loss. The physical motor functions of patients also gradually decline, presenting as unstable walking, a propensity to fall, and even possibly accompanied by urinary and fecal incontinence.
