A new study has determined that it might be possible to diagnose Alzheimer’s disease in a person through a blood test. Scientists have been running their tests based on the DHEA hormone which seems to decrease in the people that have developed the disease.
Through a process that is known as oxidation the scientists were able to encourage the body of those without Alzheimer to produce more DHEA hormones however this was not possible with the patients that did have the disease.
This led the scientists to prove that there was indeed a correlation between the inability of the Alzheimer patients to produce more of the hormone and their cognitive impairment. This was followed by their statement that they have no doubt that by running blood tests on a patient they can diagnose if the disease is present.
Doctors have mentioned that this is a great step in the diagnosis of the disease in its early stages because currently they are only able to give a definite diagnosis on a deceased person by examining their brain tissue. The advancement in this study is the fact that if Alzheimer’s disease is diagnosable through a blood test then other mental conditions will be ruled out when examining a patient.
Researchers also determined that once the disease has been diagnosed – especially in its early stages – they can start therapy and treatment for it. At the same time they can continue to study the evolution of the disease once it’s being treated.
There are over 26 million people suffering from Alzheimer’s all over the world and this number is expected to grow to 106 million in the next 40 years.
Researchers are confident that the blood testing is only the beginning of more to be discovered about the disease.
