Plain-language summary
1. beta-Amyloid peptide (A beta), a 39 -- 43 amino acid peptide, is believed to induce oxidative stress and inflammation in the brain, which are postulated to play important roles in the pathogenesis of Alzheimer's disease. Ferulic acid is an antioxidant and anti-inflammatory agent derived from plants; therefore, the potential protective activity of ferulic acid against A beta toxicity in vivo was examined. 2. Mice were allowed free access to drinking water (control) or water containing ferulic acid (0.006%). After 4 weeks, A beta 1-42 (410 pmol) was administered via intracerebroventricular injection. 3. Injection of control mice with A beta 1-42 impaired performance on the passive avoidance test (35% decrease in step-through latency), the Y-maze test (19% decrease in alternation behaviour), and the water maze test (32% decrease in percentage time in platform-quadrant). In contrast, mice treated with ferulic acid prior to A beta 1-42 administration were protected from these changes (9% decrease in step-through latency; no decrease in alternation behaviour; 14% decrease in percentage time in platform-quadrant). A beta 1-42 induced 31% decrease in acetylcholine level in the cortex, which was tended to be ameliorated by ferulic acid. 4. In addition, A beta 1-42 increased immunoreactivities of the astrocyte marker glial fibrillary acidic protein (GFAP) and interleukin-1 beta (IL-1 beta) in the hippocampus, effects also suppressed by pretreatment with ferulic acid. 5. Administration of ferulic acid per se unexpectedly induced a transient and slight increase in GFAP and IL-1 beta immunoreactivity in the hippocampus on day 14, which returned to basal levels on day 28. A slight (8%) decrease in alternation behaviour was observed on day 14. 6. These results demonstrate that long-term administration of ferulic acid induces resistance to A beta 1-42 toxicity in the brain, and suggest that ferulic acid may be a useful chemopreventive agent against Alzheimer's disease.

Key findings
- These results demonstrate that long-term administration of ferulic acid induces resistance to A beta 1-42 toxicity in the brain, and suggest that ferulic acid may be a useful chemopreventive agent against Alzheimer's disease.

How this study scored 40/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, studied in people and randomized / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multicenter collaboration, so those were left out: it earned 23 of the 58 points we could judge it on, which is 40 out of 100.
