<unk>  <unk> , also called malresorptive hydrocephalus, is a form of communicating hydrocephalus in which excess cerebrospinal fluid (CSF) occurs in the ventricles, and with<unk>  or slightly elevated cerebrospinal fluid pressure. As the fluid builds up, it causes the ventricles to enlarge and the pressure inside the head to increase, compressing surrounding brain tissue and leading to neurological complications. The disease presents in a classic triad of symptoms, which are urinary incontinence, dementia, and gait deviations. The disease was first described by Salomón Hakim and Adams in 1965. The treatment is surgical placement of a ventriculoperitoneal shunt to drain excess CSF into the lining of the abdomen where the CSF will eventually be absorbed.<unk>  is often misdiagnosed as Parkinson's disease (due to gait) or Alzheimer's disease (due to cognitive dysfunction).
