The search for a cure for Alzheimer’s disease is getting more competitive. Recent controversies have raised questions about research integrity. In 2022, a study linking beta-amyloid to Alzheimer’s was questioned for using fake data. And in 2021, a drug targeting beta-amyloid was approved by the FDA despite uncertain evidence.
Researchers have mainly focused on beta-amyloid, but new thinking is emerging. Some believe Alzheimer’s is caused by the brain’s immune system attacking itself. This mistaken attack leads to the loss of brain function and dementia.
Other theories suggest Alzheimer’s may be linked to issues with mitochondria, brain infections, or metal handling. With over 50 million people affected by dementia worldwide, innovative ideas are needed to tackle this public health crisis.
Understanding Alzheimer’s better is crucial for those living with dementia and for our healthcare system. More research is needed to find effective treatments and support those affected by this challenging disease.
