We all know about the horrifying Alzheimer’s disease.Earlier called Dementia when it was first discovered,this disease has increased steadily in recent years. One of its symtoms is high memory loss. The danger arises from the fact that it can go from very mild to extremely severe if it is not detected during its early stages.
Dopamine, is a hormone that is secreted by special neuron cells. A study lead by well known scientists has discovered that a loss of cells in the brain that use dopamine affect the parts of the brain that control important memory functions. Long term memory loss is a part of both the Alzheimer’s and Parkinson’s disease, thus a significant drop in the levels of dopamine in the blood may drastically increase the risk of either of these diseases due to destruction of dopamine producing cells.
Recently, scientists from The University Of Central Florida have designed a sensor that acts at microscopic levels and uses nanotechnology to detect even the tiniest traces of dopamine in the blood with high efficiency ,this requires only a few drops of blood and can detect Alzheimer’s or Parkinson’s in there early stages.
