What are typical symptoms of hydrocephalus?

Which type? Acute high pressure hydrocephalus can bring headache, vomiting, nausea, papilledema (retinal swelling), sleepiness or coma (unarousable unresponsiveness). Chronic "normal pressure hydrocephalus" occurs over years and brings "magnetic" gait disturbance, then cognitive impairment (inattentive, slowed thinking) and finally bladder incontinence associated with lack of concern or embarrassment.
