Researchers Reveal Alzheimer’s Treatment That Fully Restores Memory Function

Researchers Reveal Alzheimer’s Treatment That Fully Restores Memory Function


Millions of people experiencing the early onset of Alzheimer’s Disease (AD) begin to feel their memory slip away slowly. Advanced stages of Alzheimer’s often leave the victim unable to recall the names and faces of their loved ones.

“I know what I want to say; I just can’t find the words.”

Alzheimer’s is a brain disease that causes a slow decline in memory, thinking and reasoning skills. The toll that the condition takes on a person and their loved ones is overwhelming.

“The findings suggest that repeating scanning ultrasound may be a noninvasive method with potential for treating Alzheimer’s disease.” – Gerhard Leinega and Jürgen Götz

Per, Alzheimer’s disease:

– is the 6th leading cause of death in the United States.

– is developed by someone every 66 seconds.

– claims the life of 1 in 3 senior citizens.

– kills more people than breast cancer and prostate cancer combined.

– affects more than 5 million Americans, a number that could rise to 16 million by 2050.

– costs the U.S. healthcare system nearly $259 billion annually; this amount may eclipse $1.1 trillion by 2050.

A Quick Background

Alzheimer’s disease was discovered in 1906 by Dr. Alois Alzheimer in his one of his female patients, Auguste Deter. Mrs. Deter “experienced memory loss, paranoid, and psychological changes.” Following her death at age 66, Dr. Alzheimer noted the shrinkage in and around nerve cells in her brain during the autopsy.

Both the psychological and physiological symptoms as described by Dr. Alzheimer are caused by amyloid plaques and neurofibrillary tangles.

Amyloid is a protein that is found throughout the body; one that, for reasons unknown, abnormally modifies, producing a form of beta-amyloid which is toxic to neurons within the brain.

Neurofibrillary tangles are masses of defective tau protein – a stabilizing molecule abundant within neurons of the central nervous system (CNS). Tau protein that is defective, as is the case in AD patients, can not correctly regulate a critical element of cellular transport structures. This results in the disruption of mineral transfer, such as nutrients, to the brain.

A Ray of Hope

Since Dr. Alzheimer first discovered the disease that bears his name in 1906, few breakthroughs have been made. All of the treatments that have gained widespread use have had some degree of success in the relief of symptoms. No drug or therapy, however, has successfully altered the devastating progression of AD.

In 2015, researchers from the Queensland Brain Institute (QBI) at the University of Queensland in Australia came up with a novel solution for clearing the brain of neurotoxic amyloid plaques: ultrasound technology.

The technique, called focus therapeutic ultrasound, non-invasively projects super-fast sound waves into brain tissue. The fluctuation of signals allows them to penetrate the blood-brain barrier (BBB), which acts as a layer of protection against bacteria and toxins.

Stimulation of the BBB activates waste removal cells, called microglial cells. In the study, published in the journal Science Translational Medicine, researchers report “fully restoring the memory function of 75 percent of the mice they tested it on, with zero damage to surrounding brain tissue.”

To test cognition, scientists developed three methods: a maze, an object-recognition, and an avoidance task. All of the treated mice “displayed improve performance” in the administered tasks.

“We’re extremely excited by this innovation of treating Alzheimer’s without using drug therapeutics,” said Jürgen Götz, one of the study’s co-authors. “The word ‘breakthrough’ is often misused, but in this case I think this really does fundamentally change our understanding of how to treat this disease, and I foresee a great future for this approach.”


Focused Ultrasound: Present Day

Any time a new treatment method is discovered, it must undergo numerous clinical trials. Clinical trials are essential in determining not only treatment validity, but treatment safety.

This is where focused ultrasound therapy is today.

Per the Focused Ultrasound Foundation, the therapy is designed as “an early-stage, non-invasive, therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with Alzheimer’s disease.”
