The present invention concerns new approaches for the diagnosis and treatment of dementia diseases. In particular, the present invention pertains to new markers for diagnosing dementia diseases as well as to new targets for the treatment of dementia diseases.
delta-Valerobetaine (delta VB), a constitutive metabolite of ruminant milk, is produced in the rumen from free dietary N-epsilon- trimethyllysine occurring ubiquitously in vegetable kingdom. The biological role of delta VB is poorly known. Here, the anti-oxidant and anti-inflammatory potential of buffalo milk delta VB was tested in vitro during high-glucose (HG)-induced endothelial damage. Results indicated that delta VB (0.5 mM) ameliorated the HG cytotoxicity (0.57 +/- 0.02 vs 0.41 +/- 0.018 O.D. (P < 0.01). Interestingly, buffalo milk extracts enriched with delta VB showed improved significant efficacy in decreasing reactive oxygen species, lipid peroxidation, and cytokine release during HG treatment compared to milk extracts alone (P < 0.05). It is noteworthy that delta VB reduced the HG-activated inflammatory signal by modulating SIRT1 (0.96 +/- 0.05 vs 0.85 +/- 0.04 AU), SIRT6 (0.82 +/- 0.04 vs 0.61 +/- 0.03 AU), and NF-kappa B (0.85 +/- 0.03 vs 1.23 +/- 0.03 AU) (P < 0.05). On the whole, our data show the first evidence of delta VB efficacy in reducing endothelial oxidative stress and inflammation, suggesting a potential role of this betaine as a novel dietary compound with health-promoting properties.

Embodiments of the invention include determining whether an individual has autism spectrum disorder or is at risk for developing autism spectrum disorder or at risk for regression of or into autism spectrum disorder. Specific embodiments include the determination of indicative levels of carnitine or other metabolites in carnitine biosynthesis and may include assaying for mutations in TMLHE, including in exon 2, for example. In some cases one can assay for mutations in TMLHE in the absence of biochemical analysis of carnitine biosynthesis metabolites. An individual with deficiency in TMLHE and/or carnitine levels may be administered carnitine, acetylcarnitine, butyrobetaine, or a combination thereof, for example.
