Is Dementia listed as an Axis 1 disorder?

Dementia is not classified as an Axis I disorder in the DSM-IV-TR (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision). Instead, it is categorized under the neurocognitive disorders in the DSM-5, which replaced the Axis system. The focus in the DSM-5 is on a more integrated approach to diagnosis, emphasizing the underlying neurological conditions contributing to cognitive impairment.
