suicidal thoughts, depressed cognition, delusions, overvalued ideas, obsessions, phobias and preoccupations. One should separate the thought content into pathological thought, versus non-pathological thought. Importantly one should specify suicidal thoughts as either intrusive, unwanted, and not able to translate in the capacity to act on these thoughts (mens rea), versus suicidal thoughts that may lead to the act of suicide (actus reus). Abnormalities of thought content are established by exploring individuals' thoughts in an open-ended conversational manner with regard to their intensity, salience, the emotions associated with the thoughts, the extent to which the thoughts are experienced as one's own and under one's control, and the degree of belief or conviction associated with the thoughts.

Delusional symptoms can be reported as on a continuum from: full symptoms (with no insight), partial symptoms (where they may start questioning these delusions), nil symptoms (where symptoms are resolved), or after complete treatment there are still delusional symptoms or ideas that could develop into delusions you can characterize this as residual symptoms. Delusions can suggest several diseases such as schizophrenia, schizophreniform disorder, a brief psychotic episode, mania, depression with psychotic features, or delusional disorders. One can differentiate delusional disorders from schizophrenia for example by the age of onset for delusional disorders being older with a more complete and unaffected personality, where the delusion may only partially impact their life and be fairly encapsulated off from the rest of their formed personality.
