Mental disorders caused by brain alterations due to primary brain disease, systemic or other disease that secondarily affects the brain or an exogenous toxic substance (excluding alcohol and psychotropas substances classified in F10-F19). These disorders have in common that their clinical features do not allow themselves to make a diagnosis of presumption of an organic mental disorder, such as dementia or delirium. On the contrary, their clinical manifestations are similar or identical to those of disorders not considered "organic" in the specific sense. Its inclusion here is justified by the presumption that its etiology is a disease or cerebral dysfunction that acts directly and that they are not simply the expression of a fortuitous association with such disease or dysfunction or of psychological reaction to its symptoms, such as disorders schizophreniform associated with long -term epilepsy.

Diagnosis guidelines
- Evidence of a disease, injury or cerebral dysfunction or a systemic disease that can be accompanied by one of the mentioned syndromes.
- Temporary relationship (weeks or a few months) between the development of the underlying disease and the beginning of the psychopathological syndrome.
- Remission of mental disorder when improves or sends the alleged underlying cause.
- Absence of another possible etiology that could explain psychopathological syndrome (for example, very loaded family history or the presence of a precipitating stress).
Conditions a) and b) justify a provisional diagnosis, but diagnostic certainty increases considerablely if the four are present.
The following disorders are those that most likely give rise to the syndromes included here: epilepsy, limbic encephalitis, Huntington disease, cranial trauma, brain neoplasms, extracranial neoplasms with remote impact on the central nervous system (especially carcinoma of the pancreas) , vascular disease, vascular lesions or malformations, lupus erythematosus and other collagen diseases, endocrine diseases (especially hypothyroidism and hyperthyroidism, cushing disease), metabolic disorders (hypoglycemia, porphyria, hypoxia), tropical diseases and parasitic diseases (tripanosomiasis), Toxic effects of non-psychotropic psychotropas (propanolol, 1-Dopa, methyl-dopa, spheroid, antihypertensive and antimalaric).
Excludes:
Mental disorders associated with delirium (F05).
Mental disorders associated with dementia (F00-F03).
F06.0 organic hallucinosis
Disorder characterized by persistent or recurring hallucinations, normally visual or auditory, which are presented in a clear state of consciousness and that may or may not be recognized as such by those who suffer from them. A delusional elaboration of hallucinations may occur, but the most frequent is that disease awareness be preserved.
Diagnosis guidelines
In addition to the general guidelines described (F06), the presence of persistent or recurring hallucinations is necessary in any of its modalities and the absence of obnubilation of consciousness, of significant intellectual deterioration, of memory disorder and predominance of delusional ideas.
Includes:
Dermatozoic delirium.
Organic hallucinatory state (non -alcoholic).
Excludes:
Alcoholic hallucinosis (F10.52).
Schizophrenia (F20).
F06.1 organic catatonic disorder
Disorder characterized by a decreased psychomotor activity (stupor) or augmented (agitation), which is accompanied by catatonic symptoms. Both poles of psychomotor disorders can be alternated. It is unknown if in these organic pictures the complete range of the catatonic disorders described in schizophrenia can be presented. Nor could it have been clarified in a conclusive way if an organic catatonic state can occur with a clear state of consciousness or if it is always a manifestation of a delirium, with a subsequent total or partial amnesia. This implies taking care when diagnosing such a state and carefully evaluating the guidelines for the diagnosis of Delirium. It is usually accepted that encephalitis and carbon monoxide poisoning give rise to this syndrome more frequently than other organic causes.
Diagnosis guidelines
The general guidelines to accept an organic etiology, exposed in F06 should be satisfied. In addition, one of the following symptoms must be presented:
- Stupor (decrease or total absence of spontaneous movements with partial or total mutism, negativism and rigid postures maintained).
- Agitation (frank motor restlessness with or without aggressive trends).
- Both states (passing rapidly and unforeseen from hyperactivity).
Other catatonic phenomena that increase the reliability of the diagnosis are: stereotypes, famous flexibility and impulsive acts.
Excludes:
Catatonic schizophrenia (F20.2).
Dissociative stupor (F44.2).
Stupor without specification (R40.1).
F06.2 Delirious ideas disorder (schizofreniforrne) organic.
Disorder whose clinical picture predominates persistent or recurring delusional ideas. Delusional ideas can be accompanied by hallucinations but these are not limited to their content. Suggestive traits of schizophrenia, such as bizarre hallucinations or thought disorders may occur.
Diagnosis guidelines
The general guidelines to accept an organic etiology, exposed in F06 should be satisfied. In addition, delusional ideas (persecution, bodily transformation, jealousy, disease or death of oneself or another person) must occur). They may also be present hallucinations, thought disorders or isolated catatonic phenomena. Consciousness and memory should not be affected. This diagnosis should not be done if the alleged organic causal relationship is not specific or is limited to findings such as a dilation of the brain ventricles visualized in a computerized axial tomography or by minor neurological signs ("soft").
Includes:
Paranoid or hallucinatory organic states.
Epilepsy schizophreniform psychosis.
Excludes:
Transitional acute psychotic episode (F23).
Psychotic disorders due to psychotropic substance consumption (F1X.5).
Persistent delusional ideas disorder (F22).
Schizophrenia (F20).
F06.3 organic (affective) humor disorders
Disorder characterized by mood depression, decreased vitality and activity. Any other of the characteristic depressive episode features (see F30) can also be present (see F30). The only criterion for the inclusion of this State in the Organic Section is an alleged direct causal relationship with a brain or somatic disorder, whose presence must be demonstrated with independence, for example, through adequate clinical and complementary exploration or deduced from of adequate ananmésic information. Depressive syndrome should be the consequence of the alleged organic factor and not be the expression of the emotional response to the knowledge of its presence or the consequences of the symptoms of a concomitant brain disorder. Post -infectious depression are prototypical (for example, the one that follows a flu, which must be encoded here). But the mild, persistent euphoria, which does not reach the rank of hypomania (which appears, for example, in association with steroid therapy or with antidepressant drugs) should not be encoded here, but in F06.8.
Diagnosis guidelines
General guidelines must be satisfied to accept an organic etiology. In addition, the requirements of F30-F33 must be submitted.
Excludes:
Humor disorders (affective) non-organic or without specifying specific (F30-F39).
Organic (affective) humor disorder due to the right hemisphere injury (F07.8).
The following five characters can be used to specify the clinical picture:
F06.30 organic manic disorder. F06.31 Organic Bipolar Disorder. F06.32 Organic Depressive Disorder. F06.33 mixed organic humor disorder.
F06.4 Organic Anxiety Disorder
Table characterized by the essential features of a generalized anxiety disorder (F41.1), panic disorder (F41.0) or by a combination of both, but which is presented as a consequence of an organic disorder capable of producing a cerebral dysfunction (temporal lobe epilepsy, thyrootoxicosis or pheochromocytoma).
Excludes:
Non -organic or non -specifying anxiety disorders (F41).
F06.5 organic dissociative disorder
Disorder that satisfies the guidelines of one of the F44 disorders, dissociative disorders (conversion), and at the same time the general guidelines of organic etiology (as described in the introduction to this section).
Excludes: Dissociative disorder (conversion) non -organic or without specifying (F44).
F06.6 Emotional (asthenic) emotional disorder
State characterized by the presence of persistent emotional incontinence or lability. It is usually accepted that this disorder occurs more frequently in vasculocerebral disease and hypertension, in association with other causes.
Excludes: non -organic or non -specifying somatomorphic disorder (F45).
F06.7 Mild cognitive disorder
Disorder that can precede, accompany or succeed in somatic, brain or systemic infections or disorders (including very diverse HIV infection). There may not be a brain involvement made by neurological signs, but great discomfort or interference with activities. The limits of this category are definitely without establishing. When it is a consequence of a somatic disease from which the patient recovers, mild cognitive disorder does not last more than a few weeks. This disorder should only be diagnosed in the absence of clear mental or behavioral disorders.
Diagnosis guidelines
The main characteristic is a decrease in cognitive performance, which may include memory deterioration and concentration difficulties.
F06.8 Another mental disorder specified due to brain injury or dysfunction or somatic disease
Altered mood that occurs during treatment with spheroid or antidepressants.
Includes: epileptic psychosis without specification.
