 There are many thematic playlists on this channel. Click on the playlist tab and you will see, you will come across playlists on every conceivable topic, narcissism, upbringing and early childhood, the shared fantasy, you name it. One of the playlists is a mental health dictionary in the making. It already has the entries for the letter A and the letter B. And what comes after A and B? Children and childrenettes? Yes, the letter C. C, senor. C, Samuel. C, papa. The letter C is today's letter. Catalepsy. Catalepsy is the rigid maintenance of a position of the entire body or of an organ over extended periods of time. It's also known as waxy flexibility. Human sculptures are patients who freeze in any postural position that they are placed in, no matter how painful and unusual. This is very typical of catatonics. And this leads us of course to catatonia. Catatonia is a syndrome comprised of various signs, among which are catalepsy, they are for mentioned catalepsy, mutism, stereotypy, negativism, stupor, automatic obedience, echolalia and ecopraxia. Until recently, catatonia was thought to be related to schizophrenia, but this view has been discredited when the biochemical basis for schizo- schizophrenia has been discovered. The current thinking is that catatonia is an exaggerated form of mania, in other words an effective disorder. It is a feature of catatonics schizophrenia though and also appears in certain psychotic states and mental disorders that have organic medical roots. That's not part of the dictionary. Now, catatonic behavior, severe motoric abnormalities including stupor or catalepsy, motoric immobility or at the other end of the spectrum agitated excessive purposeless repeated motoric activity, nothing response to external stimuli or triggers. Also, apparently, motive less resistance or indifference to attempts to be moved or to be communicated with extreme negativism as it is known. Catatonic behavior often comprises mutism, posturing, stereotype motion, echolalia and ecopraxia. CCMD, Chinese classification of mental disorders. Yes, the Chinese have their own DSM. The Chinese equivalent of the DSM is currently in its third edition, edition number three. It recognizes culture-bound syndromes. For example, coral is diagnosable and treatable mental health disorders and that sets it apart from the DSM. Seria flexibilitas literally walks like flexibility. In the common form of catalepsy, the patient offers no resistance to the rearrangement of his limbs or to the realignment of her posture. In seria flexibilitas, there is some resistance, though it is very mild, much like the resistance of a sculpture made of soft walks. Hence, of course, the word seria walks. Circumstantiality. Don't you just love these $10 works? 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. It's a bit reminiscent of word salad in psychotic disorders. Clanged associations. Rhyming or punning associations of words with no logical connection or any discernible relationship between the words. Typical of manic episodes, psychotic states and schizophrenia. Clouding. Also known as clouding of consciousness. The patient is wide awake, 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 a lack of oxygen. A proper lack of oxygen. Cognitive dissonance. Actually, a proper extreme pain. Cognitive dissonance. When someone holds simultaneously two conflicting views, thoughts, values or bits of information which call for diametrically opposed decisions or actions. This state of things generates an inner conflict and triggers several primitive, infantile defense mechanisms such as denial, splitting, projection and reaction formation. Next, in the letter C of the Mental Health Dictionary. Compulsion. Involuntary repetition of a stereotyped and ritualistic action or movement, usually in connection with a wish or a fear. The patient is aware of the irrationality of the compulsive act. In other words, she knows that there is no real connection between her fears and wishes and what she's repeatedly compelled to do. Most compulsive patients find their compulsions tedious, bothersome, distressing and unpleasant. But resisting the urge results in mounting anxiety from which only the compulsive act provides much needed relief. Compulsions are common in obsessive compulsive disorders, obsessive compulsive personality disorder, OCPD and in certain types of schizophrenia. Schizophrenia is a superstar in the letter C. Concrete thinking. Inability or diminished capacity to form abstractions or to think using abstract categories. The patient is unable to consider and formulate hypotheses or to grasp and apply metaphors. Only one layer of meaning is attributed to each word or phrase and figures of speech are taken literally. Consequently nuances are not detected or appreciated. A common feature, it is a common feature of schizophrenia, autism spectrum disorder and certain organic disorder. Concrete thinking. Confrabulation. The constant and unnecessary fabrication of information or events to fill in gaps in the patient's memory, biography or knowledge or to substitute for unacceptable reality. It is common in schizophrenia, in certain types of cluster B personality disorders, for example narcissistic, histrionic, borderline and dissocial. In organic memory impairment, Korsakov syndrome, dementia and in the amnestic syndrome, amnesia. Next, conflict tactics scale or CTS. A diagnostic test invented in 1979. It is a standardized scale of frequency and intensity of conflict resolution tactics, especially abusive strategy used by members of a diet in a couple. Confusion. Complete the often momentary loss of orientation in relation to one's location, time and to other people. Usually the result of impaired memory often occurs in dementia or because of attention deficit for instance in delirium. Also see disorientation when we come to the letter D, which I can hint is after the letter, follows the letter C. And finally, culture bound syndrome, recurrent dysfunctional behavior linked to troubling experiences regarded in a specific location by its native denizens or in a specific culture as aberrant or sick. And with this optimistic note, we finish the letter C. See you later in the letter D.
