There is a problem with the recently approved Alzheimer’s drug, Aduhelm. It can remove some of the amyloid that forms brain plaques that are hallmarks of the disease. But most of the drug is wasted because it hits an obstacle, the blood-brain barrier, that protects the brain from toxins and infections but also prevents many drugs from entering.Researchers wondered if they could improve that grim result by trying something different: they would open the blood-brain barrier for a short time while they delivered the drug. Their experimental method was to use highly focused pulses of ultrasound along with tiny gas…

Marijuana is neither as risky nor as prone to abuse as other tightly controlled substances and has potential medical benefits, and therefore should be removed from the nation’s most restrictive category of drugs, federal scientists have concluded.The recommendations are contained in a 250-page scientific review provided to Matthew Zorn, a Texas lawyer who sued Health and Human Services officials for its release and published it online on Friday night. An H.H.S. official confirmed the authenticity of the document.The records shed light for the first time on the thinking of federal health officials who are pondering a momentous change. The agencies…

The U.S. defense secretary is facing scrutiny after failing to immediately disclose to the White House his recent prostate-cancer diagnosis and a related hospitalization, a breach of protocol for which he has apologized.But while the secretary, Lloyd J. Austin III, as a cabinet member, faces certain expectations about what he must disclose publicly regarding his health, and when he should do it, mental health experts who work with patients who have serious illnesses, such as cancer, say that reticence is common — even in the era of oversharing online.“I see it with my patients all the time,” said Dr. Andrew…

In early 2020, the Food and Drug Administration responded to decades of escalating concerns about a commonly prescribed drug for asthma and allergies by deploying one of its most potent tools: a stark warning on the drug’s label that it could cause aggression, agitation and even suicidal thoughts.The agency’s label, which was primarily aimed at doctors, was supposed to sound an alert about the 25-year-old medication, Singulair, also known by its generic name, montelukast. But it barely dented use: The drug was still prescribed to 12 million people in the United States in 2022.Children face the greatest risks of the…

As Covid rises again, killing about 1,500 Americans each week, medical researchers are trying to understand why so few people are taking Paxlovid, a medicine that is stunningly effective in preventing severe illness and death from the disease.A study of a million high-risk people with Covid found that only about 15 percent who were eligible for the drug took it. If instead half of the eligible patients in the United States had gotten Paxlovid during the time period of the research, 48,000 deaths could have been prevented, the authors of the study, conducted by the National Institutes of Health, concluded.It’s…
