Monosymptomatic clinical course of posttraumatic normal pressure hydrocephalus

Triad of Hakim--Adams is well known for normal pressure hydrocephalus (NPH): dementia, gait disturbances and urinary incontinence. Variability of intensity of these symptoms is obvious. However in clinical practice all classic signs are present. We describe a case of posttraumatic NPH producing only gait impairment with intact intellect and memory and bladder function. Such reports were not found in literature.
