Understanding that objective diagnostic methods must be based on scientific practice, Kraepelin had been conducting psychological and drug experiments on patients and normal subjects for some time when, inhe left Dorpat and took up a position as professor and director of the psychiatric clinic at Heidelberg University.

The Creation of Psychoanalysis, Harper Perennial: Dementia is an ancient term which has been in use since at least the time of Lucretius in 50 B. In the March fifth edition of PsychiatrieKraepelin expressed confidence that his clinical methodinvolving analysis of both qualitative and quantitative data derived from long term observation of patients, would produce reliable diagnoses including prognosis:.

Karl Kahlbaum made an appeal for the adoption of the clinical method in psychiatry in his book on catatonia. In the seventh,edition of PsychiatrieKraepelin accepted the possibility that a small number of patients may recover from dementia praecox. Historical and obsolete mental and behavioural disorders History of psychiatry Obsolete medical terms Schizophrenia.

Over the years, the term “dementia praecox” was gradually replaced by ” schizophrenia “, which remains in current diagnostic use.

Dementia praecox

After a while, the notes para;hrenia taken out of the box, the diagnoses were listed, and the case was closed, the final interpretation of the disease was added to the original diagnosis. He eventually concluded that it was not possible to distinguish his categories on the basis of cross-sectional symptoms. Kraepelin thus finally conquered France via America. In the eighth edition of Kraepelin’s textbook, published in four volumes between andhe described eleven forms of dementia, and dementia praecox was classed as one of the “endogenous dementias”.

He argued that, without knowing the underlying cause of dementia praecox or manic-depressive illness, there could be no disease-specific treatment, and recommended demwntia use of long baths and the occasional use of drugs such as opiates and barbiturates for the amelioration of distress, as well as occupational activities, where suitable, for all institutionalized patients.

Therefore, he argued, a research programme into the nature of psychiatric illness should look at a large number of patients over time to discover the course which mental disease could take. These terms, however, are still found in paraphremia psychiatric nomenclature. Attacking the “brain mythology” of Meynert and the positions of Griesinger and SndKraepelin advocated that the ideas of Kahlbaum, who was then a marginal and little known figure in psychiatry, should be followed.


In Bleuler’s schizophrenia rose in prominence as an alternative to Kraepelin’s dementia praecox. These findings have many implications for the ways in which mental illness is conceptualized and classified.

Dowbiggin inaccurately states that Morel used the term on page of the first volume of his publication Etudes cliniques Dowbigginp. One hundred patients of a psychiatry ward were divided into two main groups based on their diagnosis—schizophrenia or bipolar mood disorder. Dementla the next instance the term is used to argue that the illness course for those who suffer mania does not normally terminate in an early form of dementia Morelp. This division, commonly referred to as the Kraepelinian dichotomyhad a fundamental impact on pzraphrenia psychiatry, though it has also been questioned.

Without Kahlbaum and Hecker there would be no dementia praecox. The primary disturbance in dementia praecox was seen paraphrenja be a disruption in cognitive or mental functioning in attention, memory, and goal-directed behaviour. Instead the French maintained an independent classification system throughout the 20th century.

What convinced me of peaecox superiority of the clinical method of diagnosis followed here over the traditional one, was the certainty with which we could predict in conjunction with our new concept of disease the ;araphrenia course of events. It is first mentioned in The New York Times in The ICD still uses “hebephrenic” to designate the third type. It was applied as a means of setting apart a group of young men and women who were suffering from “stupor.

Some argued that existing diagnoses such as “delusional prarcox or “adolescent insanity” were better or more clearly defined. Kraepelin died while working on the ninth edition of Psychiatrie with Johannes Lange —who finished it and brought it to publication in Schizophrenia seemed to be more prevalent and more psychogenic and more treatable than either Kraepelin or Bleuler would have allowed.

Eugen Bleuler reported in that in many cases there was no inevitable progressive decline, there was temporary remission in some cases, and there were even cases of near recovery with the retention preacox some residual defect. As a direct result of the effort to construct Research Diagnostic Criteria RDC in the s dementiq were independent of any clinical diagnostic manual, Kraepelin’s idea that categories of mental disorder should reflect discrete and specific disease entities with a biological basis began to return to prominence.

There was also no mention of the dire prognosis Kraepelin had made. Chicago Medical Book Co. But it was not until and that the first three American publications regarding dementia praecox appeared, one of which was a translation of a dejentia sections of Kraepelin’s 6th edition of on dementia praecox.


The class, dementia praecox, comprised the paranoid, catatonic and hebephrenic psychotic disorders, and these forms were found in the Diagnostic and Statistical Manual of Mental Disorders until the fifth edition was released, in May Kraepelin contrasted this with manic-depressive psychosis, now termed bipolar disorderand also demejtia other forms of mood disorderincluding major depressive disorder. Scientific Research An Academic Publisher.

Based on his theory that dementia praecox is the product of autointoxication emanating from the sex glands, Kraepelin experimented, without success, with injections of thyroid, gonad and other glandular extracts. Both theorists insisted dementia praecox is a biological disorder, not the product of psychological praeccox. In this way, we were able to see what kind of mistakes had been made and were able to follow-up the reasons for the wrong original diagnosis. From Wikipedia, the free encyclopedia.

Kraepelin viewed dementia praecox as a praecoox deteriorating disease from which no one recovered.

Psychiatric nosology in the nineteenth-century was chaotic and characterised by a conflicting mosaic of contradictory systems. He did not conceptualise their state as irreversible and thus his use of the term dementia was equivalent to that formed in the eighteenth century as outlined above.

Morel described several psychotic disorders that ended in dementia, and as a result he may be regarded as the first alienist or psychiatrist to develop a diagnostic system based on presumed outcome rather than on the current presentation of signs and symptoms. Schizophrenia was mentioned as an alternate term for dementia praecox in the Statistical Manual. In the first instance the reference is made in relation to young girls of asthenic build who have often also suffered from typhoid.

Prognosis course and outcome began to feature alongside signs and symptoms in the description of syndromes, and he added a class of psychotic disorders designated “psychic degenerative processes”, three of which were borrowed from Kahlbaum and Hecker: The term “dementia praecox” was first used in by Arnold Pick —a professor of psychiatry at Charles University in Prague. Dementia praecox was characterized by disordered intellectual functioning, whereas manic-depressive illness was principally a disorder of affect or mood; and the former featured constant deterioration, virtually no recoveries and a poor outcome, while the latter featured periods of exacerbation followed by periods of remission, and many complete recoveries.
