Growing older comes with its challenges, but few are as daunting as Alzheimer’s disease. This condition gradually erodes essential brain functions, stripping away the ability to think clearly and remember. As Alzheimer’s progresses, familiar faces and places become unrecognizable, leaving individuals trapped in a confusing maze of memories. The emotional toll of losing one’s mental faculties can be overwhelming, leading to frustration and despair.
In 1995, Dr. Rudy Tanzi identified genes linked to Alzheimer’s, marking a significant step in understanding the disease. However, current treatments mainly focus on managing symptoms rather than offering a cure. Some researchers, like Professor Christian Holscher from Lancaster University in England, are hopeful that existing medications might hold the key to more effective treatments or even a cure.
Holscher is particularly interested in the potential of diabetes drugs to combat Alzheimer’s. By enhancing certain properties of these drugs, he aims to help brain cells repair themselves and slow the disease’s progression, at least in animal models.
Think of the brain as a complex biological computer. Alzheimer’s disrupts this system, leading to more than just memory loss—it impairs the ability to learn new information. Neurons, the brain’s communication cells, rely on electrical signals and chemical exchanges across synapses. Supporting cells, like astrocytes and microglia, help keep the brain clean by removing debris.
In Alzheimer’s, proteins called beta-amyloid accumulate, forming plaques and tangles that suffocate neurons. This buildup spreads, causing inflammation and hindering neuron communication, ultimately leading to brain shrinkage.
Despite understanding the disease’s mechanics, finding ways to prevent, treat, or cure Alzheimer’s remains challenging. Professor Holscher and his team are exploring new avenues, particularly focusing on the relationship between type 2 diabetes and Alzheimer’s. Insulin, a hormone involved in energy uptake and cell repair, plays a crucial role. When insulin signaling is disrupted, neurons suffer.
Holscher’s team hypothesized that diabetes drugs could help prevent Alzheimer’s. Recent studies have shown promising results, with some diabetes medications benefiting brain health. They developed a new drug that targets multiple pathways, enhancing the protective effects seen in previous treatments.
Tests on mice have shown encouraging outcomes. Mice genetically modified to mimic Alzheimer’s symptoms showed improved learning and memory when treated with the new drug. These mice demonstrated increased synaptic activity, reduced amyloid plaques, and less tau protein buildup—key indicators of Alzheimer’s progression.
The potential to improve these critical brain functions offers hope that the drug could halt the disease in humans and possibly repair some neuronal damage. However, it’s crucial to note that treating diabetes alone won’t cure Alzheimer’s. The drugs being tested are a specific subgroup that appears effective for brain health.
For this promising drug to become a viable treatment, it must transition from animal models to human clinical trials. The question remains: will Holscher’s triple receptor treatment work in humans as it does in mice? More research and time are needed to find out. Unfortunately, time is of the essence, as someone develops Alzheimer’s every 66 seconds, according to the Alzheimer’s Association.
Currently, over 5 million people in the United States live with Alzheimer’s, a number expected to triple by 2050. As the population ages, the cost of care will rise significantly, driving the urgent need for a cure. Despite funding challenges, researchers like Tanzi remain hopeful.
“We aim for early prediction, detection, and intervention,” Tanzi says. “I believe we’ll have a drug cocktail that halts the disease’s progression in my lifetime.” Scientists continue to explore various research paths, some showing great promise. Professor Holscher is optimistic about his approach. “We need as many strategies as possible to increase the chances of success. So far, nothing compares to this study. I believe it will make a real difference for patients.”

They say growing old is never easy, but of all the ailments we endure, few are as frustrating, pervasive, and deadly as the disease that steals the mind: Alzheimer’s disease. This illness deteriorates vital brain function, robbing patients of their most basic cognitive abilities. As the disease progresses, the familiar becomes foreign; friends and family turn into strangers. Alzheimer’s often leaves patients lost in a draining pool of memories. The frustration, depression, and agitation from not being able to find what they want in their own mind is devastating.
In 1995, Dr. Rudy Tanzi discovered Alzheimer’s susceptibility genes. He knows that, at the moment, managed care is about the best Alzheimer’s patients and their families can expect. However, some Alzheimer’s researchers, including Professor Christian Holscher at England’s Lancaster University, believe that the foundation for treatment, and perhaps even a cure, may lie in our existing inventory of drugs.
Holscher is optimistic that they can produce a drug that genuinely helps people with Alzheimer’s disease. By highlighting and improving upon certain properties of currently available diabetes drugs, they aim to normalize the type of growth factor in the brain, helping cells to repair themselves and improve Alzheimer’s development, at least in animals.
If we think of our brain as a biological computer, Alzheimer’s damages our data banks and eventually shorts out the whole system. It’s more than memory loss; it’s the inability to learn. Initially, as information is taken in, it cannot be registered in a healthy brain. Neurons communicate through electrical charges and the release of chemicals across tiny gaps called synapses. Other cells, called astrocytes and microglia, keep the brain clean by sweeping away unwanted debris. In an Alzheimer’s brain, excess proteins called beta-amyloid build up, creating plaques and tangles that essentially choke the neurons from the inside. The tangles spread and infect healthy nerve cells, leading to inflammation and a downward spiral in the ability of neurons to communicate, causing the brain to shrink.
Despite knowing the mechanics of the disease, scientists remain largely at a loss as to how to prevent, treat, and cure Alzheimer’s. However, Professor Holscher and his team think they may be on the verge of something monumental. They observed clear improvements in their studies. Since type 2 diabetes is a leading risk factor for Alzheimer’s, Holscher wanted to investigate the impact of insulin, which signals neurons to take up energy, grow, and repair. If this signal is missing, neurons start to suffer.
They hypothesized that existing diabetes drugs could help prevent the development of Alzheimer’s. Recent studies had already shown positive results of some diabetes drugs in combating brain ailments like Alzheimer’s and Parkinson’s disease. Holscher’s team developed a next-generation drug that targets multiple mechanisms and improves upon current diabetes treatments. This new drug activates three different types of receptors and signaling pathways, suggesting that its protective effect is more significant.
Conclusions were reached thanks to three groups of test mice with varying abilities to learn and remember. Ordinary mice are very quick, while transgenic mice, which express human genes that produce amyloid plaques, are slower. However, when treated with the new drug, the Alzheimer’s mice learned at a speed comparable to normal mice, demonstrating that the drug can protect learning and memory formation. Additional analysis showed increased synaptic activity in the brains of treated mice, a reduced rate of amyloid tangles and plaques, and diminished tau buildup—all encouraging signs.
The fact that they can improve these important parameters in the brain gives hope that this drug can stop the disease in the human brain and even repair some neurons, potentially restoring some of the impairments seen in patients. However, it’s important to note that treating diabetes will not treat Alzheimer’s; it’s much more complicated than that. They have tested several diabetes drugs that work well for diabetes but do not affect the brain. The class of drugs they are working with is a special subgroup that seems to be effective.
To prove successful, this new and still unnamed drug must move from mouse models to human clinical trials. Will Holscher’s triple receptor treatment work on people the same way? The answer requires more tests and time. Unfortunately, time isn’t always a reliable ally; according to the Alzheimer’s Association, someone develops the disease every 66 seconds. The amyloid and tau pathology begins 15 to 20 years before symptoms appear, meaning that virtually all of us, with some exceptions, start making plaques and tangles after age 40.
Today, in the United States alone, more than 5 million people live with Alzheimer’s, a number expected to triple by 2050. As America ages demographically, the costs of caring for those with Alzheimer’s will skyrocket. These numbers provide critical motivation for researchers to find a cure. Even if funding continues to be a challenge, researchers like Tanzi remain optimistic.
“We’ll have a program for eradication based on early prediction, early detection, and early intervention,” he says. “In my lifetime, I believe we will at least have a cocktail of drugs that will stop the disease from progressing.” To reach that goal, scientists continue to explore multiple paths of inquiry, some showing great promise. Professor Holscher believes he is on the right track. “You want to have as many approaches as you can fund because then you increase the chance of something really working out. However, so far, we have nothing that can compare to this type of study. I think this is going to be really good; we’re going to see something that genuinely will make a difference in patients.”
