Nanoparticles for drug delivery to the brain from each drug injection with these nanoparticles showed remarkable improvements in the effects of the drug relative to non-nanoparticle delivery systems. This possibly suggests that nanoparticles could provide a promising solution to how these drugs could cross the BBB. One factor that still must be considered and accounted for is nanoparticle accumulation in the body. With long-term and frequent injections that are often required to treat chronic diseases such as Alzheimer's disease, polymeric nanoparticles could potentially build up in the body, causing undesirable effects. This area for concern would have to be further assessed to analyze these possible effects and
