Nose-to-Brain Drug Delivery by Nanoparticles in the Treatment of Neurological Disorders

Ask your doctor which drug therapies are close enough to needing this drug delivery system to stop the neuronal cascade of death.  I bet s/he has no clue what this is about, thus letting your neurons die due to inaction. Good luck with that.
I've written about 13 other nasal delivery options here.

Nose-to-Brain Drug Delivery by Nanoparticles in the Treatment of Neurological Disorders

Abstract

Many potential drugs for the treatment of neurological diseases are unable to reach the brain in sufficient enough concentrations to be therapeutic because of the blood brain barrier. On the other hand, direct delivery of drugs to the brain provides the possibility of a greater therapeutic-toxic ratio than with systemic drug delivery. The use of intranasal delivery of therapeutic agents to the brain provides a means of bypassing the blood brain barrier in a non-invasive manner. With this respect, nanosized drug carriers were shown to enhance the delivery of drugs to CNS compared to equivalent drug solutions formulations. Neurological conditions that have been studied in animal models that could benefit from nose-to-brain delivery of nanotherapeutics include pain, epilepsy, neurodegenerative disease, and infectious diseases. The delivery of drugs to the brain via nose-to-brain route holds great promise, on the basis of preclinical research by means of drug delivery systems such as polymeric nanoparticles (Np) and clinical data related to intranasal delivery to CNS of large molecular weight biologics administered in solution, but safety issues about toxicity on nasal mucosa, Np transport into the brain, delivery only to specific brain area and variability in the adsorbed dose still represent research topics that need to be considered with a view of clinical translation of these delivery systems.
