Abstract

This paper presented original study results concerning the prevalence and clinical characteristics of cognitive impairment associated with brain concussion. The cognitive functions of 80 consecutive patients (mean age= 37.40±11.74 years; 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.
