The cognitive functions of 80 consecutive patients （mean age = 37.40±1l.74years; 50 men and 30 women） admitted to the hospital with brain concussions were evaluated. Their cognitive scores were compared with 40 age- and education-matched healthy volunteers without history of cranial trauma. Cognitive impairment without dementia was found in 93% of the patients. Cognitive impairment in brain concussion was also characterized by prominent cognitive slowness （bradyphrenia）, concentration decrease, free recall insufficiency, and visual-spatial dysfunction. Age and severity of anxiety significantly influence the cognitive performance of patients.展开更多
