    Propranolol memory


    “The effect sizes obtained for pre-reactivation propranolol in our study compare well to those obtained with the best evidence-based treatment for PTSD, namely, cognitive-behavioral therapy, as well as those obtained with the most recommended pharmacological treatment for PTSD, namely, SSRIs,” researchers wrote in the study, according to a . “Should these results be replicated in further studies, propranolol blockade of reconsolidation [of traumatic memories] may become a new therapy for some patients with PTSD.” The double-blind trial randomized 60 adults with long-standing PTSD to propranolol, a nonadrenergic beta-receptor blocker, or placebo. Participants ingested their assigned agent 90 minutes before a brief memory reactivation session—in which they were asked to write and then read aloud a detailed first-person narrative of their traumatic memory—once a week for 6 weeks. MDMA Granted Breakthrough Therapy Designation for PTSD Participants completed the patient-rated PTSD Checklist-Specific (PCL-S) at each session before receiving their treatment. At the start and end of the trial, clinicians assessed patients using the Clinician-Administered PTSD Scale (CAPS). Although PCL-S and CAPS scores were similar for both groups at baseline and both groups had decreased scores at the posttreatment assessment, decreases in the propranolol group were significantly greater, compared with the placebo group, according to the study. Antioxidant Reduces PTSD Symptoms, Cravings reported mean CAPS scores of 52.0 for the propranolol group and 69.2 for the placebo group, and mean PCL-S scores of 38.4 with propranolol and 69.0 with placebo, at a 6-month follow-up. Previous studies suggested that the β-adrenergic receptor antagonist propranolol might be a novel, potential treatment for post-traumatic stress disorder (PTSD). This hypothesis stemmed mainly from rodent studies showing that propranolol interferes with the reconsolidation of Pavlovian fear conditioning (FC). However, subsequent investigations in humans have produced controversial evidence about the effect of propranolol on fear memories and an effect on PTSD symptomatology has yet to be reported. Thus, it remains to be established whether propranolol interferes with the reconsolidation of fear memories at large. To address this question, we tested the effect of systemic injections of propranolol administered before or after the retrieval of an inhibitory avoidance (IA) memory elicited with different footshock intensities. In parallel, the same treatment was tested on the reconsolidation of Pavlovian FC. Propranolol showed no effect on the reconsolidation of IA, although the pre-retrieval administration resulted in a significant retrieval impairment.

Could propranolol help them get on with their lives by dulling the emotional sting of their memories? And almost more importantly, should.

    Propranolol is commonly used to treat high blood pressure and prevent migraines in children. But Merel Kindt and colleagues from the University of Amsterdam have found that it can do much more. By giving it to people before they recalled a scary memory about a spider, they could erase the fearful response it triggered. The critical thing about the study is that the entire memory hadn’t been erased in a typical sci-fi way. Kindt had trained the volunteers to be fearful of spidery images by pairing them with electric shocks. Even after they’d been given propranolol, they still expected to receive a shock when they saw a picture of a spider – they just weren’t afraid of the prospect. The drug hadn’t so much erased their memories, as dulled their emotional sting. Losing Your Memory: It May be the Drugs You’re Taking Is memory loss interfering with your daily life? Most people are familiar with some of the things that can impair memory, including alcohol and drug abuse, head injuries, stroke, sleep deprivation, severe stress, aging or a symptom of conditions like Alzheimer’s disease. Neel, a geriatric pharmacist with the AARP, claims:“Scientists now know that memory loss as you get older is by no means inevitable. What many do not know is that episodes of forgetfulness can also be side effects of prescription drugs. Indeed, the brain can grow new brain cells and reshape their connections throughout life.”Dr. Neel promotes education on the importance of better understanding the effects of prescription medications. Commonly prescribed drugs that induce forgetfulness in some patients include:• Antianxiety drugs (Benzodiazepines) dampen activity in key parts of the brain, including those involved in the transfer of events from short-term to long-term memory. Examples: alprazolam (Xanax), chlordiazepoxide (Librium), clonazepam (Klonopin), diazepam (Valium), flurazepam (Dalmane), and lorazepam (Ativan).• Cholesterol-lowering drugs (Statins) may impair memory and other mental processes by depleting brain levels of cholesterol. In the brain, these lipids are vital to the formation of connections between nerve cells, the links underlying memory and learning.
