Seeking a better test for Alzheimer's
Alzheimer's disease affects 5.8 million Americans. It is among the top causes of dementia. Alzheimer's is challenging to diagnose in the initial stages because it does not exhibit any symptoms until later stages. Symptoms such as memory loss appear after neurodegeneration (which takes years or decades) has already taken a toll on cognition and memory. Clinical trials that aim to reverse or slow down cellular damage brought about by Alzheimer'sdisease have failed repeatedly. Could it be because the drugs are administered too late? Researchers and scientists are yet to find out. The only way to ascertain the hypothesis is to find a way to diagnose Alzheimer's disease in people with zero symptoms then test the drugs. Scientific Developments for Alzheimer Diagnosis Biological markers rely on tests of cerebrospinal fluid and brain scans, e.g., blood tests, MRI brain scans, cerebrospinal fluid tests, genetic tests, and PET brain scans. Biomarker tests show how the
