DSM-5® Differential Diagnosis Handbook

Make Accurate Psychiatric Diagnoses with Confidence

Interactive resource that helps all clinicians improve the diagnosis of psychiatric conditions using the latest DSM-5 classifications.




All clinicians are trained to make accurate diagnoses. Beginning with the patient’s presenting symptoms, they ultimately narrow down multiple options to one condition. The DSM-5 Differential Diagnosis Handbook can play a critical role in this process by improving the diagnostic process of psychiatric conditions. Leveraging latest DSM-5 classifications from the American Psychiatric Association, users are able to use a trusted 6-step process when dealing with, sometimes unfamiliar, psych conditions.

Exclusive, integrated interactive decision trees provide a step-by-step process of asking yes or no questions to find a tentative diagnosis. When the initial diagnosis is reached, tables of differential diagnoses are presented to help confirm or present new options.

Apple Watch compatibility:

Users that purchase this product for their iPhone and own an Apple Watch will be able to download this app to their phone and pair it directly with the watch. The Apple Watch will allow users to use the step-by-step interactive decision trees to find tentative diagnoses directly on the watch itself.
