Neurospectroscopy with respect to its past, present and future has been reported. It is helpful to understand the biochemical relevance of each of the major resonances in the brain spectra. Lactate is seen in the spectrum as a doublet at 1.33 ppm. Healthy tissues do not have sufficient lactate to be detectable by MRS. Neurospectroscopy provides information on brain constituents. Pattern recognition blends pattern recognition techniques and multivariate statistical analysis with solid, comprehensive software engineering practices. Neurospectroscopy offers a window into the chemistry of the human brain, reporting on normal mechanisms as well as the changes that occur with degeneration, disease, pain, cancer, and infection. Alzheimer's disease can now be identified much earlier than before offering earlier management before the disease progresses. The long-term effect of shaken baby syndrome and traumatic brain injury can be gauged by neurospectroscopy.
