Gait problems, urinary incontinence and dementia are symptoms of hydrocephalus but does anyone know why they occur? I would greatly appreciate the help.

Hmm..this was explained on UW ,lemme see how well I can recall😉

Incontinence: hydrocephalus stretches the descending paraventricular cortical fibers to the bladder.

There are 3 regions that control the micturition reflex: S2-S4 ( which control cholinergic tonicity of bladder), cerebral cortex descending paraventricular fibers( inhibit micturition,thus keep incontinence at bay) and pontine reticular centre ( PRF) -which relax the external urethral sphincter( void urine).

Gait troubles: due to impacting/stretching of cerebellar region involved, if it is vermis then it is truncal , if cerebellar hemispheres then limb ataxia.

Dementia: hmm....enlarged ventricles ,so guess this compromises the cortex,Don't take my word on this one 😳

Hope the first two help! Lemme know if u need further info.
