Infection and Extragastric Diseases-A Focus on the Central Nervous System.

() is most known to cause a wide spectrum of gastrointestinal impairments; however, an increasing number of studies indicates that infection might be involved in numerous extragastric diseases such as neurological, dermatological, hematologic, ocular, cardiovascular, metabolic, hepatobiliary, or even allergic diseases. In this review, we focused on the nervous system and aimed to summarize the findings regarding infection and its involvement in the induction/progression of neurological disorders. Neurological impairments induced by infection are primarily due to impairments in the gut-brain axis (GBA) and to an altered gut microbiota facilitated by colonization. Currently, regarding a potential relationship between infection and neurological disorders, most of the studies are mainly focused on .
