Alzheimer’s disease were divided into six types

Scientists from the U.S. made a statement that Alzheimer’s disease is not one disease, and six species with characteristic differences. It is the perception of this disease as a single disease does not allow science and medicine to progress in the development of effective medications and therapies for getting rid of him – the opinion of the researchers found in Science Daily.

To the conclusion that Alzheimer’s should be divided into six different types, scientists came after research in which participated 4050 people with late stage of this neurodegenerative disease. The average age of participants was 80 years.

“Like breast cancer, different types of Alzheimer’s disease should be considered and studied separately. These features must be taken into account when testing drugs,” summed up in the end, the authors of the project.
In the study, they analyzed the cognitive abilities of participants with Alzheimer’s disease. This analysis made it possible to divide patients into six different groups. Were they participants differ in different performance parameters such cognitive health, memory, Executive functioning, speech and visual-spatial functioning. Someone were evenly weakened all of these abilities, someone was down only some of them.

Continuing the study using genetic analysis, experts were able to identify 33 of the variant single-nucleotide polymorphism (simultaneous existence of several allelic varieties of a gene) related to specific cognitive disorders. For example, one of those was a variant of the gene APOE, which correlated with memory impairment.

“Alzheimer’s can develop in different ways. Perhaps it is because the attempt to develop a single cure for this disease have failed. The choice of therapy in Alzheimer’s disease needs to be specific and individual,” said the authors.
