Can you add concentrations

What happened to the laser-sharp focus you once enjoyed? Like a computer that slows with use, the brain accumulates wear and tear that affects processing. Daffner says this can be caused by a number of physiological stressors such as inflammation, injury to blood vessels especially if you have high blood pressure , the buildup of abnormal proteins, and naturally occurring brain shrinkage.
