Symptoms are the patient's complaints. They are highly subjective and amenable to suggestion and to alterations in the patient's mood and other mental processes.
Catalepsy
"Human sculptures" are patients who freeze in any posture and position that they are placed, no matter how painful and unusual. Typical of catatonics.
Catatonia
A syndrome comprised of various signs, amongst which are: catalepsy, mutism, stereotypy, negativism, stupor, automatic obedience, echolalia, and echopraxia. Until recently it was thought to be related to schizophrenia, but this view has been discredited when the biochemical basis for schizophrenia had been discovered. The current thinking is that catatonia is an exaggerated form of mania (in other words: an affective disorder). It is a feature of catatonic schizophrenia, though, and also appears in certain psychotic states and mental disorders that have organic (medical) roots.
Cerea Flexibilitas
Literally: wax-like flexibility. In the common form of catalepsy, the patient offers no resistance to the re-arrangement of his limbs or to the re-alignment of her posture. In Cerea Flexibilitas, there is some resistance, though it is very mild, much like the resistance a sculpture made of soft wax would offer.
Circumstantiality
When the train of thought and speech is often derailed by unrelated digressions, based on chaotic associations. The patient finally succeeds to express his or her main idea but only after much effort and wandering. In extreme cases considered to be a communication disorder.
Clang Associations
Rhyming or punning associations of words with no logical connection or any discernible relationship between them. Typical of manic episodes,psychotic states, and schizophrenia.
Clouding
(Also: Clouding of Consciousness)
The patient is wide awake but his or her awareness of the environment is partial, distorted,or impaired. Clouding also occurs when one gradually loses consciousness (for instance, as a result of intense pain or lack of oxygen).
