Why is there no remedy for Alzheimer’s—or why aren’t there medicines that may at the least considerably sluggish or meaningfully ameliorate the illness? It afflicts greater than 6 million Individuals, with that quantity on its technique to doubling inside a era.

Alzheimer’s is a hideous ailment for each the victims and their households and associates. But although the illness was first recognized by psychiatrist Alois Alzheimer within the early 1900s, progress in combating it has been nearly nonexistent. What’s scandalous is that for many years analysis has been nearly totally targeted on the unsuitable speculation.
Dr. Alzheimer famous within the post-mortem of the affected person’s mind with the illness that got here to bear his title that it was densely loaded with two proteins referred to as plaques and tangles. Sadly, the dominant thesis in analysis on the illness has been that attacking plaques, and to a lesser extent tangles, would remedy the ailment and allow the mind to regain its well being.
Alzheimer himself warned about focusing an excessive amount of on plaques and tangles as causes. Actually, some victims of Alzheimer’s have proved to have had little in the best way of plaques, whereas others who had plaques didn’t have the illness.
Nonetheless, regardless of fixed failures—some 20 medication have been developed that ended up as flops—and the expenditure of tens of billions of {dollars}, the principle thrust of analysis stays targeted on combating plaques.
The obsession with this dead-end strategy has been fanatical, nearly cultlike. Researchers who need to pursue extra promising avenues have confronted critical obstacles. Hardly ever has persistent failure resisted correction on one thing so vital.
You will have heard of a brand new drug referred to as lecanemab, which is being heralded as a implausible breakthrough. However lecanemab relies on the wrongheaded plaques speculation. As famous well being coverage journalist Joanne Silberner sadly factors out, “At greatest, lecanemab would possibly barely sluggish a affected person’s inevitable decline for a couple of months.”
This analysis scandal exhibits the hazard of groupthink, significantly when there’s a robust authorities company such because the Nationwide Institutes of Well being placing the kibosh on grants for nonconsensus tasks.
A basic case of comparable groupthink concerned the reason for abdomen ulcers. The once-prevailing view was that stress and way of life had been the trigger, and medicines and regimens had been developed on that perception.
This dogma was challenged by two Australian physicians, Robin Warren and Barry Marshall. They posited that the villain was micro organism and that antibiotics had been the reply for a everlasting remedy. When not ignored, their discoveries had been derided. Solely after a few years and fixed, typically unorthodox advocacy, particularly by Dr. Marshall, did the medical world settle for their truths. The 2 had been finally awarded the Nobel Prize in Medication.
Within the case of Alzheimer’s, the inflexible analysis mentality has begun to melt, however solely barely. To assault this lethal rigidity, Congress ought to maintain hearings on the topic, beginning with the leaders on the Nationwide Institutes of Well being.
