The remarkable, potential human and economic value of antidepressants in preventing, arresting and alleviating Alzheimer’s Disease: A MiniReview by Julian Lieb, M.D.
Twenty years ago, researchers knew that depression often accompanies and predisposes to the Alzheimer’s disease, the obvious inference: why not use antidepressants to preve0nt and treated Alzheimer’s.
However, medical science is often incidental to those indifferent to exploiting the misfortunes of others. Today’s figure is $100,000,000 for preventing Alzheimer’s, with research based on the widely discredited genome.

BIOCHEMICAL AND PHARMACOLOGICAL INTERPRETATIONS
As depression predisposes to Alzheimer’s disease, it is not surprising that antidepressants are capable of preventing, alleviating and arresting the disorder.
Excessive synthesis of prostaglandin E2 generates amyloid, and such non-steroidal anti-inflammatory drugs as aspirin and ibuprofen, as well as antidepressants, inhibit prostaglandin E2.
Two epidemiological studies have shown that ibuprofen (Motrin), that inhibit prostaglandin E2, can delay the onset of Parkinson’s disease, a neurodegenerative disorder closely related to Alzheimer’s.
Antidepressants offer great advantages, and few disadvantages, in addressing Alzheimer’s, recently referred to as “the coming tsunami,” but you would not think so, given the lack of enthusiasm of Alzheimer’s organizations and health policy makers, when notified of this innovation.
One suspects that conflicts of interest, and the low cost of generic antidepressants, are the root causes of the neglect.
The right to the highest attainable standard of health is codified in numerous legally binding international and regional human rights treaties. The right, or other health-related rights, is also enshrined in over 100 constitutions worldwide.

Everyone has the right to freedom of opinion and expression; this right includes freedom to hold opinions without interference and to seek, receive and impart information and ideas through any media and regardless of frontiers.
