This PhD work, carried out by Lluís Samaranch, supports the theory that the majority of patients with MCI are at an intermediate stage which will end up in an acute condition. However, not all cases with mild impairment evolve to this condition.
This conclusion was arrived at after the Memory Disorder Unit at the University Hospital searched for early indicators of the ailment. Besides neuropsychological markers involved, the most significant find was the discovery of PET (Positron Emission Tomography) as a highly efficacious technique for measuring the risk of evolving MCI.
Early detection to combat the disease
This multidisciplinary research involved neuropsychologists, nurses and engineers working together.
For more than 17 months a sample of 299 patients was studied. Of these, 103 suffered some mild cognitive impairment; 80 volunteered subjective complaints regarding memory; and 54 individuals were used as a control group, made up of volunteers from the Navarre Blood Donors’ Association.
All were tested neuropsychologically and with magnetic resonance and were subjected to various analyses and a genetic risk markers examination, amongst other procedures. Thanks to all this, the team came to the conclusion that the illness can be identified at early stages, before irreversible damage occurs, albeit with costly techniques such as the PET.
This is why the team insists on the necessity to find new, more accessible and simpler biochemical markers but with the same predictive capacity. In this manner we can undertake therapeutic intervention in the initial stages of Alzheimer – precisely when there are more possibilities of success.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
