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.
