Cognitive disorder in brain concussion

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.

Key words： brain concussion; cognitive impairment

Compliance with ethics guidelines

All procedures were followed in accordance with the ethical standards of the responsible committee on human experimentation (institutional – University committee of ethical standards in the field of dissertation “Cognitive impairment in mild and moderate cranial trauma,” national and with the Helsinki Declaration of 1975 as revised in 2000. Informed consent was obtained from all the patients for being included in the study.

Vladimir Zakharov, Ekaterina Drozdova and Nikolay Yakhno declare that they have no conflict of interest.
