PREVIOUS AND NEXT TERMS--------------------------------------
Delusion of reference
A delusion whose theme is that events, objects, or other persons in one's immediate environment have a particular and unusual significance. These delusions are usually of a negative or pejorative nature, but also may be grandiose in content. This differs from an idea of reference, in which the false belief is not as firmly held nor as fully organized into a true belief.
Denial
A defense mechanism where certain information is not accessed by the conscious mind. Denial is related to repression, a similar defense mechanism, but denial is more pronounced or intense. Denial involves some impairment of reality. Denial would be operating (as an example) if a cardiac patient who has been warned about the potential fatal outcome of engaging in heavy work, decides to start building a wall of heavy stones.
Depersonalization
An alteration in the perception or experience of the self so that one feels detached from, and as if one is an outside observer of, one's mental processes or body (e.g., feeling like one is in a dream).
Derailment
Loosening of associations. A pattern of speech in which a person's ideas slip off one track onto another that is completely unrelated or only obliquely related. In moving from one sentence or clause to another, the person shifts the topic idiosyncratically from one frame of reference to another and things may be said in juxtaposition that lack a meaningful relationship. This disturbance occurs between clauses, in contrast to incoherence, in which the disturbance is within clauses. An occasional change of topic without warning or obvious connection does not constitute derailment.
Derealization
An alteration in the perception or experience of the external world so that it seems strange or unreal (e.g., people may seem unfamiliar or mechanical).
Dereistic
Detachment
A behavior pattern characterized by general aloofness in interpersonal contact; may include intellectualization, denial, and superficiality.
Disconnection syndrome
Term coined by Norman Geschwind to describe the interruption of information transferred from one brain region to another.
Disinhibition
Freedom to act according to one's inner drives or feelings, with less regard for restraints imposed by cultural norms or one's superego; removal of an inhibitory, constraining, or limiting influence, as in the escape from higher cortical control in neurologic injury, or in uncontrolled firing of impulses, as when a drug interferes with the usual limiting or inhibiting action of GABA within the central nervous system.
Disorientation
Confusion about the time of day, date, or season (time), where one is (place), or who one is (person).
Dysphoric mood
An unpleasant mood, such as sadness, anxiety, or irritability.
