[EX Q]: Question: Does brivaracetam differentially affect voltage-gated sodium currents without impairing sustained repetitive firing in neurons?
Answer: The lack of effect of BRV on SRF in neurons suggests that the reported inhibition of BRV on VGSC currents does not contribute to its antiepileptic properties.
[EX A]: yes

[EX Q]: Question: Are screening tests enough to detect hemineglect?
Answer: Hemineglect may not be recognized with single screening tests commonly used. The use of a standard battery is recommended to improve diagnostic sensitivity in individuals with various subtypes of hemineglect.
[EX A]: no

[EX Q]: Question: Is weight loss at the time of diagnosis associated with prognosis in patients with advanced-stage non-small cell lung cancer?
