Common Detection of Early Signs of Alzheimer’s

The most common method of detecting the early signs of Alzheimer’s disease is a technique known as positron emission tomography (PET), which is a nuclear medicine medical imaging technique.  PET scans and images show the metabolic degeneration of the brain.  In a patient showing early signs of Alzheimer’s, this technique is essential in recognizing the limited dysfunctional areas of the brain. 

Early Signs of Alzheimers

A PET scan shows a very reliable pattern for early signs of Alzheimer’s disease, such that certain areas of the brain have decreased metabolism when the disease first starts its progression.  In fact, this method has the ability to detect the early signs of Alzheimer’s several years before a physician can make the same diagnosis.  In addition, this technique also offers experts a way to differentiate early signs of Alzheimer’s disease from similar neurological disorders.   

A number of other techniques to detect the early signs of Alzheimer’s disease are currently being researched and developed, including a PET-like test that measures biochemical activity in the brain, rather than brain structure.   As well, research is being completed to develop a convenient, cheap and easy method that could revolutionize diagnosis:  a blood test.

Unfortunately, there is no cure for Alzheimer’s disease, no matter how early it is detected.  However, several new drugs are being developed and FDA approved, which can delay the progression of Alzheimer’s symptoms.  With luck, substantial improvements in the diagnosis and treatment of this condition.  With the constant advances in detection of early signs of Alzheimer’s, we may even see the day when this disorder becomes a completely preventable one.
