Neurological disorders in cattle comprise a group of economically relevant diseases with high occurrence and mortality. In this way, the objective was to carry out an epidemiological study of the diseases with neurological manifestations in cattle admitted (alive or dead) to the Garanhuns Bovine Clinic/Federal Rural University of Pernambuco (CBG/UFRPE) from January 2009 to December 2019. Epidemiological information was collected from the clinical records regarding the age group, rearing system, time of year, and area of origin of the animals. The diseases were grouped into categories according to their origin: toxic or toxi-infectious, viral, traumatic/physical, parasitic, metabolic degenerative, bacterial, neoplastic, and others. A total of 6103 cattle were treated during the study period, of which 604 (10.1%) were diagnosed with diseases that had neurological manifestations. Of these, 331 cases were of single occurrence, and 231 cases occurred as outbreaks in the herd. Death was the outcome in almost 80% of the cases (465/596). The frequencies of the different categories were toxic or toxi-infectious (25.2%), viral (21.5%), traumatic/physical (13.6%), parasitic (9.8%), metabolic (9.3%), degenerative (2.3%), bacterial (2.2%), neoplastic (1.2%), and others (1.2%). It was found that almost half of the animals were older than 24 months (229/475), almost 80% were females, more than 60% were submitted to a semi-intensive to intensive rearing system, and the occurrence of disease was higher during the dry period of the year (363/614). The three most frequent neurological diseases in this study were rabies, trauma, and botulism.Keywords: diseases of viral origin; epidemiological study; hospital routine; neurological diseases; retrospective study
