Cluster-A disorders have to distinguished from delusional disorder (persecutory type), schizophreniform, bipolar disorder with psychotic symptoms and schizophrenia. Post-traumatic stress disorder (PTSD) can also have interchangeable presenting complaints to the cluster-C PDs.. Thus, Axis-1 disorders and Axis-2 disorders have similar presentation and needs to be evaluated and ruled out before making the diagnosis of Axis-2 disorders.

Additionally, many patients with PDs also suffer from co-morbid conditions like mood disorders, substance abuse and organic brain lesions which have overlapping symptoms and signs with PDs. This requires a complete long history including duration of symptoms and developmental history and essential investigations.
