Normal pressure hydrocephalus (NPH) is a condition whereby the ventricles are pathologically enlarged with normal intracranial opening pressure. Here, we highlight a rare case of NPH who first presented atypically to psychiatry team. There were emotional and behavioral changes following a road traffic accident that subsequently presented as acute stress reaction with ataxic gait. CT brain showed NPH. Lumbar puncture was done to relieve intracranial pressure. Patient gradually recovered without any neurological or psychological deficit. In conclusion, a high clinical suspicion is important to identify NPH and prompt treatment should be offered to optimize the clinical outcome.
