How many categories are in the DSM?

The Diagnostic and Statistical Manual of Mental Disorders (DSM) contains five main categories, known as the axes, which were used in earlier editions. However, the most current edition, the DSM-5, has shifted to a non-axial system and focuses on a single-axis diagnosis that encompasses all mental health disorders. The DSM-5 includes a wide range of categories for various mental health conditions, grouped primarily under broad headings like mood disorders, anxiety disorders, psychotic disorders, and more.
