Neuro-related disorders will be rising globally. Current treatments have numerous limitations that can impair patients’ quality of life. One of the key therapeutic approaches is promoting neuroplasticity. Neuroplasticity plays a vital role in memory, learning, and recovery of function after neural damage. Acetaminophen (Paracetamol; APAP) has been suggested as a neuroprotective treatment through modulation of neuroplasticity dose-duration dependently. This systematic review was conducted across major databases such as PubMed/MEDLINE, Google Scholar, Scopus, and Web of Science, between 2002 and October 2025, and from an initial pool of 537 articles, we selected only English-language studies with complete methodology and full results reporting the effects of acetaminophen on neuroplasticity. Preclinical evidence suggests that short-term, low-dose acetaminophen can have neuroprotective effects. Acetaminophen is metabolized in the brain to AM404, which activates TRPV1, inhibit COX-1/COX-2,

FAQ
Why are researchers studying acetaminophen for neurological conditions?
Neuro-related disorders are expected to rise globally, and current treatments have numerous limitations that can impair quality of life. Acetaminophen, also called paracetamol or APAP, has been suggested as a neuroprotective treatment through modulation of neuroplasticity, and this systematic review gathers studies on that effect.
Why does neuroplasticity matter in this acetaminophen research?
Neuroplasticity plays a vital role in memory, learning, and recovery of function after neural damage. Promoting it is described as one of the key therapeutic approaches for neuro-related disorders, which is why a possible effect of acetaminophen on neuroplasticity is of interest.
How was this systematic review on acetaminophen conducted?
The authors searched PubMed/MEDLINE, Google Scholar, Scopus and Web of Science, covering 2002 to October 2025. From an initial pool of 537 articles, they selected only English-language studies with complete methodology and full results that reported the effects of acetaminophen on neuroplasticity.
Can low-dose acetaminophen protect the brain?
Possibly, but only preclinical evidence is described. That evidence suggests short-term, low-dose acetaminophen can have neuroprotective effects. The summary describes acetaminophen’s modulation of neuroplasticity as dose- and duration-dependent, so the finding refers to short-term, low-dose use rather than any dose or length of use.
What does acetaminophen turn into in the brain?
Acetaminophen, also called paracetamol or APAP, is metabolized in the brain to a compound called AM404. According to the review summary, AM404 activates TRPV1 and inhibits the COX-1 and COX-2 enzymes. This brain metabolism is part of how acetaminophen is thought to act beyond simple pain relief.
