Approximately 26.9% (n=79,442) of these episodes were associated with documented psychiatric comorbidity (22.1% for female hospitalizations and 32.2% for male hospitalizations). Patients with recorded psychiatric comorbidity were younger (66.2±16.2 vs. 68.6±17.2 for those without psychiatric comorbidity, p<0.001), exhibited a lower overall in-hospital mortality rate, and experienced significantly longer mean hospital stays. Among these comorbidities, `Delirium, dementia, amnestic, and other cognitive disorders¿ were documented in 7.4% (n=21,965) of hospitalizations, followed by alcohol-related disorders in 6.5% (n=19,302) and mood disorders in 6.1% (n=18,079). Epilepsy/seizures had the highest recorded psychiatric comorbidity rate among neurological disorders (39.9%).</jats:p></jats:sec><jats:sec id="S092493382400186X_sec0283" sec-type="conclusions"><jats:title>Conclusions</jats:title><jats:p>Psychiatric comorbidity is present in more than a quarter of hospitalizations with a primary diagnosis of neurological disorders.
