Analysis of the influence of bromazepam on cognitive performance through the visual evoked potential (P300)

Abstract: Benzodiazepines have been used in the pharmacological treatment of anxiety for over four decades. However, very few studies have combined bromazepam and event-related potentials (ERP). The present study aimed at investigating the modulatory effects of this drug on brain dynamics. Specifically, the effects of bromazepam (3mg) on the P300 component of the ERP were tested in a double-blind experiment. The sample, consisting of 15 healthy subjects (7 male and 8 female), was submitted to a visual discrimination tas… Show more

“…Such findings can be associated to the effect of the medication, which facilitated the activation and improvement of the motor control mechanisms, by "reducing" the anxiety levels occasioned by the task situation [17]. Further justifying the result of our study, another research's did not find any significant difference in the reaction time between the bromazepam and control groups, through a visual discrimination task, also using the oddball paradigm and visuomotor task [15,26].…”

“…Some studies report cases of healthy subjects using this drug, with the main objective of producing cognitive improvement, especially with regards to memory and attention [14]. On the other hand, bromazepam, an anxiolytic drug with a depressive effect on the CNS, is therapeutically utilized to produce sedation, induce sleep, relieve anxiety and muscle spasms, in addition to preventing convulsions [15]. Studies prove its efficacy in treating anxiety disorder, although they highlight the drug side effects in tasks involving sensorimotor integration [16][17][18][19][20][21].…”

“…Bromazepam, possibly the most commonly employed benzodiazepine, has been used in the pharmacological treatment of anxiety since the early 60's. Its mechanism of action on the Central Nervous System is believed to be related to the ability to enhance the activity of gamma aminobutyric acid (GABA), the major inhibitory neurotransmitter (Kopp et al 2004, Puga et al 2005.…”
