A year into the COVID-19 pandemic, life in some ways is still a cross between Groundhog Day and The Shining , and a fleck of Alice in Wonderland where “nothing would be what it is because everything would be what it isn’t.” While some relief has arrived in the form of COVID-19 vaccinations, seeking the so-called “herd immunity,” finding a balance between conservative and liberal narratives, continues to be a moving target. Given growing concerns about COVID-19 variants worldwide, many are now saying we need a Marshall Plan for global vaccinations. I’ve never been a fear monger, but my late mother always told me to stay on task. So a year into the pandemic and its related closures and disruptions, the task is to look backward and forwards without getting dizzy. Bring on the Dramamine… No easy task, particularly for those, like me, in the throes of Alzheimer’s and other forms of dementia . My mom and several close family members lost to the cause know the path well. … [Read more...] about COVID-19 vs. Alzheimer’s: A Rocky Prizefight!

Source: Courtesy of RIKEN A groundbreaking new study on rats by researchers at the RIKEN Brain Science Institute in Japan reports for the first time that learning and unlearning fear involves two distinct populations of neurons in the locus coeruleus (LC) of the brainstem that transmit signals to either the amygdala or prefrontal cortex (PFC) using noradrenaline.

Source: stocksmap/pixabay I am often asked whether it is possible to have a successful long-term romantic relationship with a narcissist or whether it is possible to have a happy marriage when your mate has untreated narcissistic personality disorder . Unfortunately, the answer to both questions is “no.’ While many people with narcissistic personality disorder are very charming and convincing when they are courting you, they lack the emotional maturity and relationship skills to make a real relationship work. Once you are past the courtship stage and the novelty of having you interested in them is over, they are going to start to treat you badly. How badly will they treat you? What will they do? In general, narcissists use the same relationship behaviors with all their mates. If you listen closely to how they talk about their former mates, why they broke up, who is to blame, and what they did to retaliate, you will have a fairly reliable preview of how they will … [Read more...] about 5 Reasons Not to Start a Relationship with a Narcissist

Reports of opioid addiction and overdose are found throughout the media and scientific literature. However, an opioid-related outcome that gets little attention is hearing loss. The first documented case of opioid-induced hearing loss (OIHL) dates all the way back to the 1970s, but we still know very little about this condition. Research on OIHL is scarce, so it isn’t entirely clear how prevalent OIHL is or exactly how opioids cause hearing loss. What we do know is that hearing loss can sometimes occur after an episode of opioid misuse. One study documented a case of a 20-year-old man who presented to the emergency department with acute onset of hearing loss in both ears after ingesting a high dose of methadone. Fortunately, his hearing loss resolved after a few days of abstinence. But OIHL can … [Read more...] about Can Opioid Misuse Cause Hearing Loss?
