Beta-blockers can prevent and mitigate damage, but could one of them potentially heal?

Beta-adrenergic drugs represent one group of pharmaceuticals that are frequently prescribed in the treatment of hypertension. Although some earlier beta-blockers were potentially associated with undesirable cognitive (and other) side effects, the central nervous system impact of some more recent drugs in this category has been minor, absent, or occasionally, even favorable.

Recent research has suggested that the beta-blocker metoprolol might have especially favorable effects on human cognitive functions and task performance. Moreover, this drug may aid performance in settings where improvements are probably not generated by the anxiolytic effect.
