BackgroundNeurodegenerative diseases are disorders in which nerve cells start to lose function due to different causes. Like many other illnesses, they are considered to be highly prevalent in the 22 Arabic-speaking countries known to constitute the Arab world. The two most prevalent neurodegenerative disorders are Alzheimer's disease and Parkinson's disease.AimThe aim of this paper is to assess the amount of research dedicated to neurodegenerative diseases by the Arab countries during a 15-year period, between 2005 and 2019.MethodsThe number of publications by each Arab country as well as some non-Arab speaking countries was retrieved from PubMed. Publications in top 10 neuroscience journals were also tracked using the same method with each journal's name included. The numbers were then normalized with respect to the average population and average gross domestic product (GDP) in each country to eliminate bias.ResultsArab countries were shown to contribute only 1,311 (0.774%) of the 169,330 articles published worldwide on neurodegenerative disorders. These 1,311 also constitute only 0.660% of the 198,869 Arab publications during the indicated period. Saudi Arabia had the highest contribution to these numbers with more than one-quarter the number of publications on neurodegenerative disorders. Approximately one-third of all neurodegenerative disease-related articles were associated with Alzheimer's disease, whereas one-fifth were related to Parkinson's disease. For the top 10 neuroscience journals, only a minimal contribution by Arab countries was noted.ConclusionAlthough an increase in the number of articles by the Arab world was noted from 2013 onward, the contribution of the Arab countries on the subject to the number of publications still seems to be insufficient.
