in regards and timed to everything: I am referring to a previous document when I made some remarks that were facts also tested and there is another that concerns my daughter she has a lobed bottom right ear, her name being Mary Lou…. Much of abstraction has been left unsaid and undone in this product/milk syrup, and others due to economics, differentials, subsidies, bankruptcy, tools, buildings, bonds, national stocks, foundation craps, weather trades, government in levels of breakages, and fuses in electronics to all formerly “stated” not necessarily factuated.

Not knowing that I was ill, I made no attempt to understand what was happening, but felt that there was some overwhelming significance in all of this, produced either by God or Satan…. The walk of a stranger on the street could be a “sign” to me which I must interpret. Every face in the windows of a passing streetcar would be engraved on my mind, all of them concentrating on me and trying to pass me some sort of message

I have experienced this process chiefly as a condition in which the integrating mental picture in my personality was taken away and smashed to bits, leaving me like agitated hamburger, distributed evenly throughout the universe.
I am like a zombie living behind a glass wall. I can see all that goes on in the world, but I can't touch it. I can't reach it. I can't be in contact with it. I am outside. They are inside, and when I get inside, they aren't there. There is nothing there, absolutely nothing.
DSM-IV-TR CriteriaDSM-IV-TR CriteriaA. Two (or more) of the following during a 1-month
period:(1) delusions
(2) hallucinations
(3) disorganized speech (e.g., frequent derailment or incoherence)
(4) grossly disorganized or catatonic behavior
(5) negative symptoms, i.e., affective fl attening, alogia,or avolition
B. Social/occupational dysfunction: interpersonal relations, or self-care
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 i.e., active-phase symptoms) and prodromal or residual symptoms.
Contd…Contd…
D. Schizoaffective and mood disorder exclusion : Schizoaffective disorder and mood disorder with psychotic features have been ruled out because either
(1) no major depressive, manic, or mixed episodes 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).

F20.0 Paranoid F20.0 Paranoid Schizophrenia Schizophrenia Paranoid schizophrenia is characterized
mainly by delusions of persecution, feelings of passive or active control, feelings of intrusion, and often by megalomanic tendencies also. The delusions are not usually systemized too much, without tight logical connections and are often combined with hallucinations of different senses, mostly with hearing voices.
Disturbances of affect, volition and speech, and catatonic symptoms, are either absent or relatively inconspicuous.
F20.1 Hebephrenic F20.1 Hebephrenic SchizophreniaSchizophreniaHebephrenic schizophrenia is characterized by
disorganized thinking with blunted and inappropriate emotions. It begins mostly in adolescent age, the behavior is often bizarre. There could appear mannerisms, grimacing, inappropriate laugh and joking, pseudophilosophical brooding and sudden impulsive reactions without external stimulation. There is a tendency to social isolation.
Usually the prognosis is poor because of the rapid development of "negative" symptoms, particularly flattening of affect and loss of volition. Hebephrenia should normally be diagnosed only in adolescents or young adults.
Denoted also as disorganized schizophrenia
pseudophilosophical brooding
F20.2 Catatonic F20.2 Catatonic SchizophreniaSchizophreniaCatatonic schizophrenia is characterized
mainly by motoric activity, which might be strongly increased (hyperkinesis) or decreased (stupor), or automatic obedience and negativism.
We recognize two forms:◦ productive form — which shows catatonic
excitement, extreme and often aggressive activity. Treatment by neuroleptics or by electroconvulsive therapy.
◦ stuporose form — characterized by general inhibition of patient’s behavior or at least by retardation and slowness, followed often by mutism, negativism, fexibilitas cerea or by stupor. The consciousness is not absent.

F20.3 Undifferentiated F20.3 Undifferentiated SchizophreniaSchizophreniaPsychotic conditions meeting the
general diagnostic criteria for schizophrenia but not conforming to any of the subtypes in F20.0-F20.2, or exhibiting the features of more than one of them without a clear predominance of a particular set of diagnostic characteristics.
This subgroup represents also the former diagnosis of atypical schizophrenia.
F20.4 Post schizophrenic F20.4 Post schizophrenic DepressionDepression
A depressive episode, which may be prolonged, arising in the aftermath of a schizophrenic illness. Some schizophrenic symptoms, either „positive“ or „negative“, must still be present but they no longer dominate the clinical picture.
These depressive states are associated with an increased risk of suicide.
F20.5 Residual F20.5 Residual SchizophreniaSchizophreniaA chronic stage in the development of
schizophrenia with clear succession from the initial stage with one or more episodes characterized by general criteria of schizophrenia to the late stage with long-lasting negative symptoms and deterioration (not necessarily irreversible).
F20.6 Simple F20.6 Simple SchizophreniaSchizophrenia
Simple schizophrenia is characterized by early and slowly developing initial stage with growing social isolation, withdrawal, small activity, passivity, avolition and dependence on the others.
The patients are indifferent, without any initiative and volition. There is not expressed the presence of hallucinations and delusions.
F21 F21 Schizotypal disorderSchizotypal disorderThis disorder is characterized by
eccentric behavior and by deviations of thinking and affectivity, which are similar to that occurring in schizophrenia, but without psychotic features and expressed symptoms of schizophrenia of any type.
F22 Persistent Delusional F22 Persistent Delusional DisordersDisordersIncludes a variety of disorders in
which long-standing delusions constitute the only, or the most conspicuous, clinical characteristic and which cannot be classified as organic, schizophrenic or affective.
Their origin is probably heterogeneous, but it seems, that there is some relation to schizophrenia.
F22.0 F22.0 Delusional DisorderDelusional DisorderA disorder characterized by the
development of one delusion or of the group of similar related delusions, which are persisting unusually long, very often for the whole life.
Other psychopathological symptoms — hallucinations, intrusion of thoughts etc. are not present and are excluding this diagnosis.
It begins usually in the middle age.
F23 F23 Acute and Transient Psychotic Acute and Transient Psychotic DisordersDisorders
The criteria should be the following features:◦ acute beginning (to two weeks)◦ presence of typical symptoms (quickly
changing “polymorphic symptoms”)◦ presence of typical schizophrenic symptoms.
Complete recovery usually occurs within a few months, often within a few weeks or even days.
The disorder may or may not be associated with acute stress, defined as usually stressful events preceding the onset by one to two weeks.
F24 Induced Delusional F24 Induced Delusional Disorder Disorder
A delusional disorder shared by two or more people with close emotional links. Only one of the people suffers from a genuine psychotic disorder; the delusions are induced in the other(s) and usually disappear when the people are separated.
The psychotic disorder of the dominant member of this dyad is mainly, but not necessarily, of schizophrenic type. The original delusions of dominant member and his partner are usually chronic, either persecutory or megalomanic.
F25 Schizoaffective F25 Schizoaffective Disorders Disorders Episodic disorders in which both affective and
schizophrenic symptoms are prominent (during the same episode of the illness or at least during few days) but which do not justify a diagnosis of either schizophrenia or depressive or manic episodes.
Patients suffering from periodic schizoaffective disorders, especially with manic symptoms, have usually good prognosis with full remissions without any remaining defects.
Other subtypesOther subtypes
Pseudoneurotic schizophrenia (Hoch & Polatin—predominant neurotic symptoms last for years & has poor prognosis
