ABSTRACT
Background: Parkinson’s disease (PD) is a neurodegenerative disorder characterized by a progressive
loss of nigrostriatal dopaminergic neurons. Its treatment is symptomatic and shows limited efficacy.
Dehydroepiandrosterone (DHEA) is a hormone produced in the brain. Several studies have reported
beneficial effects of said steroid in experimental models of PD and various human diseases, but its
potential for PD is inconclusive. Therefore, it is necessary to evaluate current evidence to determine
the therapeutic potential of DHEA administration for PD since it could be an effective and low-cost
treatment.
Objectives: This scoping review protocol aims to evaluate the therapeutic potential of
dehydroepiandrosterone administration in patients with PD.
Inclusion criteria: Studies describing
patients with PD receiving DHEA, and reporting an outcome --on disease course, severity, or adverse
effects-- compared to either placebo, an inactive treatment or a standard treatment will be included.
Also, PD experimental models reporting an effect of DHEA treatment on measures of neuroprotection
(cell death, motor activity, oxidative stress) will be considered.
Exclusion criteria: Studies written in
languages different than Spanish or English that could not be appropriately translated, or whose fulltext
files could not be retrieved will be discarded. Information sources: Studies will be retrieved from
Web of Science, PubMed, Scopus, EBSCOhost, Cochrane Library, Google Scholar, and author’s
collections. No other sources will be considered.
Data charting: Data will be extracted by one
researcher and verified by another using a pilot-tested predefined format. Non-systematic review
articles (narrative, scoping or similar) will only be considered for narrative synthesis. This protocol
complies with the PRISMA 2020 statement and its main related extensions (PRISMA-A, PRISMA-P,
PRISMA-Scr). It also complies with the Manual for Evidence Synthesis of the Joanna Briggs Institute.
