WHO among us hasn’t wanted to let go of anxiety or forget about fear? Phobias, panic attacks and disorders like post-traumatic stress are extremely common: 29 percent of American adults will suffer from anxiety at some point in their lives. Sitting at the heart of much anxiety and fear is emotional memory — all the associations that you have between various stimuli and experiences and your emotional response to them. Whether it’s the fear of being embarrassed while talking to strangers (typical of social phobia) or the dread of being attacked while walking down a dark street after you’ve been assaulted (a symptom of PTSD), you have learned that a previously harmless situation predicts something dangerous. It has been an article of faith in neuroscience and psychiatry that, once formed, emotional memories are permanent. The best we could do was to get you to tolerate them, but we could never really rid you of your initial fear. The current standard of treatment for such phobias revolves around exposure therapy. This involves repeatedly presenting the feared object or frightening memory in a safe setting, so that the patient acquires a new safe memory that resides in his brain alongside the bad memory. As long as the new memory has the upper hand, his fear is suppressed. Statins are prescribed to many people to keep their cholesterol in a safer range. The Food and Drug Administration lists memory loss, forgetfulness and confusion as possible side-effects of the drug. Some people do report memory problems when taking them, but the studies conducted so far are inconclusive. Statins include: Beta-blockers, though, may also cause the loss of emotional memories. They have even been tested as a way of treating post-traumatic stress disorder because of their ability to block emotional memories. People who cannot sleep are sometimes prescribed so-called ‘Z-drugs’. These include: The ‘Z-drugs’ have been linked to memory loss: especially losing the ability to make new memories. They have also been reported to cause strange behaviours like driving or cooking with absolutely no memory of the event.
Along with its needed effects, propranolol may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.

Data have shown that cardiac conditioning can delay or attenuate this side effect of propranolol. Propranolol is used alone or together with other medicines to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. Lowering blood pressure may reduce the risk of stroke and heart attacks. Propranolol is also used to treat severe chest pain (angina), migraine headaches, or hypertrophic subaortic stenosis (thickened heart muscle). This medicine may also be used to treat irregular heartbeats, tremors, or pheochromocytoma (adrenal gland tumor).
