recognize dementia: There is a new one method for early detection
Scientists observe pupil movement
Study brings new insights: Your pupils play this role
It is a disease that puts a strain on the entire family and the environment of the person affected: Alzheimer’s – also “Alzheimer’s dementia” or “Alzheimer’s disease” – according to the Alzheimer Research Initiative, is the most common form of dementia. It is incurable disorder of the brain. nerve cells in the brain die off and people are increasing forgetful, confused and disoriented. Personality and behavior also change.
How does Alzheimer’s develop?
Of course there is several investigations and studies to this topic. Until now, however, it has not been possible to predict well whether a person will develop Alzheimer’s. But as with many illnesses, the early detection important. There are a number of risk factors and the first physical signs that point to the disease.
When researching causes Alzheimer’s has so far been on two factors limited that with the killing of neurons be associated in the brain. This leads to a progressive cognitive dysfunction. The factors are:
die clumping Proteins Yes in the brain the collection von Proteinplaques (Amyloid-Beta) in the brain
New results on dementia and Alzheimer’s: Eyes play an important role
In a study, published in the journal Neurobiology of Agingthe research team drew attention not only to the triggering factors of the disease, but to a new method that should help in early detection: the movement of the pupils in connection with cognitive tests, i.e. mental tasks.
Preventing Alzheimer’s through healthy eating: View the Hello Fresh Box
The team from the “University of San Diego” in California found out that an increased genetic risk for Alzheimer’s can be recognized by pupil movements long before the symptoms appear. Because that Brain by those affected change long before the first symptoms appear – and this change is also reflected in the pupil movements low.
To put it more precisely: the pupillary reactions of humans are controlled by the part of the brain Locus Coeruleus controlled (a neuron cluster in the brainstem). This part of the brain is for the Arousal and regulation of cognitive functions responsible.
Protein “tau” is associated with pupils and dementia
The Protein “Tau”, which clumps together in Alzheimer’s disease, is strongly associated with cognition. So while the test patients are doing their tasks, the Locus Coeruleus (the brain region) the changing diameter of the pupils.
It was found that people with mild cognitive impairment and thus also the clumped protein “Tau”, a greater dilation of the pupils and showed more cognitive effort. Nevertheless, both test groups achieved the same results.
Due to the greater dilation of the pupils during cognitive exertion, the researchers recognized slight cognitive impairments early on, although the test results did not actually reveal any deficits.
How reliable is the pupillary reaction measurement?
Since the researchers shortcut between the pupil reaction, the protein “tau” and the work of the locus coeruleus, according to the researchers, observation of the pupil can be used as a Screening-Methode can be used for early detection of the increased risk of Alzheimer’s. The method helps identify the risk of the disease before symptoms appear, making treatment easier.
Scientists are not only working on improved early detection of the disease, but have also been trying to find a cure for years. Now the development of a vaccine once morest Alzheimer’s seems to be within reach.
That is why early detection is important
This new procedure, generally the early detection of Alzheimer’s, is important for various reasons, as Professor Dr. Jens Wiltfang, board member of the Dementia Competence Network, explains on the website of the Federal Ministry of Education and Research: On the one hand, it is known that physical activity, healthy nutrition and memory training reduce Alzheimer’s disease slow it down can – but only in the early stages.
On the other hand there is medication such as lithium, which delay the disease process. They work all the more effectively, ever earlier they are taken. To the patient through lifestyle changes, mental training and medication ensure a good quality of life for a long timethe disease must be diagnosed as early as possible.
