Disorder, central auditory processing
A condition in which there is an inability to differentiate, recognize or understand sounds while both the hearing and intelligence are normal.
Disorder, cephalic
A congenital condition that stems from damage to, or abnormal development of, the budding nervous system. Cephalic is a term that means "head" or "head end of the body." Congenital means the disorder is present at, and usually before, birth.
Disorder, seasonal affective (SAD)
Depression that tends to occur (and recur) as the days grow shorter in the fall and winter. It is believed that affected persons react adversely to the decreasing amounts of light and the colder temperatures as the fall and winter progress.
Disorder, social anxiety
Excessive fear of embarrassment in social situations that is extremely intrusive and can have debilitating effects on personal and professional relationships. Also called social phobia. Phobias are persistent, irrational fears of certain objects or situations. They recognize that their fear may be excessive or unreasonable, but are unable to overcome it. The symptoms and signs of social phobia include blushing, sweating, trembling, rapid heartbeat, muscle tension, nausea or other stomach discomfort, lightheadedness, and other symptoms of anxiety.
Disorder, specific developmental
A disorder that selectively affects one area of development, sparing essentially all other areas of development. Specific developmental disorders are as opposed to pervasive developmental disorders (which affect development across the board), dyspraxias that affect multiple systems, cerebral palsy, and metabolic disorders.
Disordered thinking
A failure to be able to "think straight." Thoughts may come and go rapidly. The person may not be able to concentrate on one thought for very long and may be easily distracted, unable to focus attention. The person may be unable to connect thoughts into logical sequences, with thoughts becoming disorganized and fragmented. This lack of logical continuity of thought, termed a "thought disorder," can make conversation very difficult and may contribute to social isolation. If people cannot make sense of what an individual is saying, they are likely to become uncomfortable and tend to leave that person alone. Disorder thinking is a characteristic feature of schizophrenia.
Disorders, lymphoproliferative
Malignant diseases of the lymphoid cells and cells from the reticuloendothelial system (which take up and sequester inert particles). The lymphoproliferative disorders are in contrast to the myeloproliferative disorders which are malignancies of certain bone marrow cells including those that give rise to the red blood cells, the granulocytes (types of white blood cells), and the platelets (crucial to blood clotting).
Disorders, myeloproliferative
Malignant diseases of certain bone marrow cells including those that give rise to the red blood cells, the granulocytes (types of white blood cells), and the platelets (crucial to blood clotting). The myeloproliferative disorders include myelophthisic anemia, erythroblastic leukemia, leukemoid reaction, myelofibrosis, myeloid metaplasia, polycythemia vera, and thrombocytosis. The myeloproliferative disorders are in contrast to the lymphoproliferative disorders which are malignancies of lymphoid cells and cells of the reticuloendothelial system (such as macrophages) which can take up inert particles and sequester them.
PREVIOUS AND NEXT TERMS--------------------------------------

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
Dysphoric mood
An unpleasant mood, such as sadness, anxiety, or irritability.
Displacement
A defense mechanism, operating unconsciously, in which emotions, ideas, or wishes are transferred from their original object to a more acceptable substitute; often used to allay anxiety.

disruption in the usually integrated functions of consciousness, memory, identity, or perception of the environment. The disturbance may be sudden or gradual, transient or chronic.
Distractibility
The inability to maintain attention, that is, the shifting from one area or topic to another with minimal provocation, or attention being drawn too frequently to unimportant or irrelevant external stimuli.
Double bind
Interaction in which one person demands a response to a message containing mutually contradictory signals, while the other person is unable either to comment on the incongruity or to escape from the situation.
