Signs and Symptoms in Psychiatry

Signs and Symptoms in Psychiatry
Signs are objective; symptoms are subjective. Signs are the clinician’s observations, such as noting a patient’s agitation; symptoms are subjective experiences, such as a person’s complaint of feeling depressed. In psychiatry, signs and symptoms are not as clearly demarcated as in other fields of medicine; they often overlap. Because of this, disorders in psychiatry are often described as syndromes—a constellation of signs and symptoms that together make up a recognizable condition. Schizophrenia, for example, is more often viewed as a syndrome than as a specific disorder. This concept is expressed in the use of the terms schizophrenic spectrum or the group of schizophrenias.
GLOSSARY OF SIGNS AND SYMPTOMS
abreaction
A process by which repressed material, particularly a painful experience or a conflict, is brought back to consciousness; in this process, the person not only recalls but also relives the repressed material, which is accompanied by the appropriate affective response.
abstract thinking
Thinking characterized by the ability to grasp the essentials of a whole, to break a whole into its parts, and to discern common properties. To think symbolically.
abulia
Reduced impulse to act and to think, associated with indifference about consequences of action. Occurs as a result of neurological deficit, depression, and schizophrenia.
acalculia
Loss of ability to do calculations; not caused by anxiety or impairment in concentration. Occurs with neurological deficit and learning disorder.
acataphasia
Disordered speech in which statements are incorrectly formulated. Patients may express themselves with words that sound like the ones intended but are not appropriate to the thoughts, or they may use totally inappropriate expressions.
acathexis
Lack of feeling associated with an ordinarily emotionally charged subject; in psychoanalysis, it denotes the patient’s detaching or transferring of emotion from thoughts and ideas. Also called decathexis. Occurs in anxiety, dissociative, schizophrenic, and bipolar disorders.
acenesthesia
Loss of sensation of physical existence.
acrophobia
Dread of high places.
acting out
Behavioral response to an unconscious drive or impulse that brings about temporary partial relief of inner tension; relief is attained by reacting to a present situation as if it were the situation that originally gave rise to the drive or impulse. Common in borderline states.
aculalia
Nonsense speech associated with marked impairment of comprehension. Occurs in mania, schizophrenia, and neurological deficit.
adiadochokinesia
Inability to perform rapid alternating movements. Occurs with neurological deficit and cerebellar lesions.
adynamia
Weakness and fatigability, characteristic of neurasthenia and depression.
aerophagia
Excessive swallowing of air. Seen in anxiety disorder.

The subjective and immediate experience of emotion attached to ideas or mental representations of objects. Affect has outward manifestations that may be classified as restricted, blunted, flattened, broad, labile, appropriate, or inappropriate. See also mood.
ageusia
Lack or impairment of the sense of taste. Seen in depression and neurological deficit.

agitation
Severe anxiety associated with motor restlessness.
agnosia
Inability to understand the import or significance of sensory stimuli; cannot be explained by a defect in sensory pathways or cerebral lesion; the term has also been used to refer to the selective loss or disuse of knowledge of specific objects because of emotional circumstances, as seen in certain schizophrenic, anxious, and depressed patients. Occurs with neurological deficit. For types of agnosia, see the specific term.
agoraphobia
Morbid fear of open places or leaving the familiar setting of the home. May be present with or without panic attacks.
agraphia
Loss or impairment of a previously possessed ability to write.
ailurophobia

Subjective feeling of motor restlessness manifested by a compelling need to be in constant movement; may be seen as an extrapyramidal adverse effect of antipsychotic medication. May be mistaken for psychotic agitation.
akinesia
Lack of physical movement, as in the extreme immobility of catatonic schizophrenia; may also occur as an extrapyramidal effect of antipsychotic medication.
akinetic mutism
Absence of voluntary motor movement or speech in a patient who is apparently alert (as evidenced by eye movements). Seen in psychotic depression and catatonic states.
alexia
Loss of a previously possessed reading facility; not explained by defective visual acuity. Compare with dyslexia.

amnesia
Partial or total inability to recall past experiences; may be organic (amnestic disorder) or emotional (dissociative amnesia) in origin.
amnestic aphasia
Disturbed capacity to name objects, even though they are known to the patient. Also called anomic aphasia.
anaclitic
