DSM-IV http://cebmh.warne.ox.ac.uk/cebmh/elmh/nelmh/schizophrenia/diagnosis/d sm/page1.html says "Diagnostic criteria A. Characteristic symptoms: Two (or more) of the following, each present for a significant portion of time during a 1-month period (or less if successfully treated): delusions hallucinations disorganized speech (e.g., frequent derailment or incoherence) grossly disorganized or catatonic behavior negative symptoms, i.e., affective flattening, alogia, or avolition Note: Only one Criterion A symptom is required if delusions are bizarre or hallucinations consist of a voice keeping up a running commentary on the person's behavior or thoughts, or two or more voices conversing with each other. B. Social/occupational dysfunction: For a significant portion of the time since the onset of the disturbance, one or more major areas of functioning such as work, interpersonal relations, or self-care are markedly below the level achieved prior to the onset (or when the onset is in childhood or adolescence, failure to achieve expected level of interpersonal, academic, or occupational achievement). C. Duration: Continuous signs of the disturbance persist for at least 6 months. This 6-month period must include at least 1 month of symptoms (or less if successfully treated) that meet Criterion A (i.e., active-phase symptoms) and may include periods of prodromal or residual symptoms. During these prodromal or residual periods, the signs of the disturbance may be manifested by only negative symptoms or two or more symptoms listed in Criterion A present in an attenuated form (e.g., odd beliefs, unusual perceptual experiences). D. Schizoaffective and Mood Disorder exclusion: Schizoaffective Disorder and Mood Disorder With Psychotic Features have been ruled out because either (1) no Major Depressive Episode, Manic Episode, or Mixed Episode have occurred concurrently with the active-phase symptoms; or (2) if mood episodes have occurred during active-phase symptoms, their total duration has been brief relative to the duration of the active and residual periods. E. Substance/general medical condition exclusion: The disturbance is not due to the direct physiological effects of a substance (e.g., a drug of abuse, a medication) or a general medical condition. F. Relationship to a Pervasive Developmental Disorder: If there is a history of Autistic Disorder or another Pervasive Developmental Disorder, the additional diagnosis of Schizophrenia is made only if prominent delusions or hallucinations are also present for at least a month (or less if successfully treated). Differential diagnosis Some disorders have similar or even the same symptom. The clinician, therefore, in his/her diagnostic attempt has to differentiate against the following disorders which he/she needs to rule out to establish a precise diagnosis. Psychotic Disorder Due to a General Medical Condition, delirium, or dementia; Substance-Induced Psychotic Disorder; Substance-Induced Delirium; Substance-Induced Persisting Dementia; Substance-Related Disorders; Mood Disorder With Psychotic Features; Schizoaffective Disorder; Depressive Disorder Not Otherwise Specified; Bipolar Disorder Not Otherwise Specified; Mood Disorder With Catatonic Features; Schizophreniform Disorder; Brief Psychotic Disorder; Delusional Disorder; Psychotic Disorder Not Otherwise Specified; Pervasive Developmental Disorders (e.g., Autistic Disorder); Childhood presentations combining disorganized speech (from a Communication Disorder) and disorganized behavior (from Attention- Deficit/ Hyperactivity Disorder); Schizotypal Disorder; Schizoid Personality Disorder; Paranoid Personality Disorder.

DSM-IV http://cebmh.warne.ox.ac.uk/cebmh/elmh/nelmh/schizophrenia/diagnosis/d sm/page1.html says "Subtypes 1. Paranoid Type A type of Schizophrenia in which the following criteria are met: Preoccupation with one or more delusions or frequent auditory hallucinations. None of the following is prominent: disorganized speech, disorganized or catatonic behavior, or flat or inappropriate affect. 2. Catatonic Type A type of Schizophrenia in which the clinical picture is dominated by at least two of the following: motoric immobility as evidenced by catalepsy (including waxy flexibility) or stupor excessive motor activity (that is apparently purposeless and not influenced by external stimuli) extreme negativism (an apparently motiveless resistance to all instructions or maintenance of a rigid posture against attempts to be moved) or mutism peculiarities of voluntary movement as evidenced by posturing (voluntary assumption of inappropriate or bizarre postures), stereotyped movements, prominent mannerisms, or prominent grimacing echolalia or echopraxia 3. Disorganized Type A type of Schizophrenia in which the following criteria are met: All of the following are prominent: disorganized speech disorganized behavior flat or inappropriate affect The criteria are not met for Catatonic Type. 4. Undifferentiated Type A type of Schizophrenia in which symptoms that meet Criterion A are present, but the criteria are not met for the Paranoid, Disorganized, or Catatonic Type. 5. Residual Type A type of Schizophrenia in which the following criteria are met: Absence of prominent delusions, hallucinations, disorganized speech, and grossly disorganized or catatonic behavior. There is continuing evidence of the disturbance, as indicated by the presence of negative symptoms or two or more symptoms listed in Criterion A for Schizophrenia, present in an attenuated form (e.g., odd beliefs, unusual perceptual experiences). Associated features Learning Problem Hypoactivity Psychosis Euphoric Mood Depressed Mood Somatic or Sexual Dysfunction Hyperactivity Guilt or Obsession Sexually Deviant Behavior Odd/Eccentric or Suspicious Personality Anxious or Fearful or Dependent Personality Dramatic or Erratic or Antisocial Personality "

A medium-recent article I read said the "negative" signs and symptoms were probably actually more diagnostic -- or at least more characteristic -- than the "positive" signs and symptoms. Or, at least, that was the case among the particular abilities they were discussing; the abilities to detect and "fill in" a pattern. One test they performed, for instance, was to take a photograph of some object (e.g. a wristwatch), glue it to a sticky-board, cut it into many pieces, then remove some of the pieces. It turned out that all types of schizophrenics needed a larger minimum of pieces left in to detect that it was a wristwatch, than all types of non- schizophrenic people (whether mentally healthy or otherwise). So, the specific "negative symptoms" they had in mind were, inability to detect and/or fill-in a pattern most "normal, healthy" people could detect and fill-in. The specific "positive symptoms" they had in mind were, the tendency to detect and/or fill-in a pattern under circumstances in which most "normal, healthy" people would detect no pattern; and to "fill it in" in a manner that most "normal, healthy" people would eschew. Thus a paranoid schizophrenic, for instance, can detect proof that he or she is being stalked by the CIA, out of evidence that a "normal" person would think does not form a pattern; or, at most, forms an innocuous one.

That's interesting.

I thought so.

When I used to go with my parents to Charismatic meetings, there was a certain woman who preached in a Scottish accent, but had a South-of- -the-Mason-Dixon-line, West-of-the-Mississippi U.S.American accent when not in the pulpit. Sorry I can't remember her name. I don't know if she suffered from any disorder at all (except that some psych(iatr,olog)ists consider _all_ religious behaviour pathologicial -- e.g. the MMPI, but not the DSM). Anyway, I witnessed this first-hand.
