6 topics with concise breakdowns: definitions, key facts, and class questions.
This chapter is your main navigator through the world of mental pathology. Modern diagnostics is based on the ICD-10, and it is its strict structure that we analyze here. Without a clear understanding of the classification system, it is impossible either to pass the psychiatry exam or to formulate a diagnosis correctly in real clinical practice.
The section covers key diagnostic blocks. We will examine organic mental disorders, the spectrum of schizophrenia, schizotypal and delusional conditions, as well as affective pathologies (depression and bipolar disorder). Special attention is paid to neurotic, stress-related and somatoform disorders—the very "minor psychiatry" that doctors of any specialty encounter on a daily basis.
In classes and exams, differential diagnosis within these categories is tested most rigorously: for example, how to use ICD-10 criteria to distinguish a severe neurotic reaction from the onset of an endogenous process. Learn the diagnostic criteria—this is your basic and most reliable working tool.
Why did the need arise to transition from syndromes to nosologies?
The introduction of new treatment methods (malaria therapy, shock methods, antibiotics) required a deeper understanding of the causes and mechanisms of disease development in order to search for etiotropic therapy.
Is it mandatory to use ICD-10 in Russia?
Yes, the legislation of the Russian Federation explicitly requires the use of ICD-10 for resolving absolutely all legal and social issues in psychiatry.
Can an organic disorder be completely ruled out if MRI and EEG show no pathology?
No. An important rule applies in psychiatry: the absence of paraclinical signs does not rule out a diagnosis. The loss of higher mental functions makes it possible to diagnose a condition before the defect is visible on scans.
What is the main difference between somatogenic and exogenous disorders?
There are no fundamental differences in symptomatology, since the brain reacts identically to damaging factors. Somatogenic disorders are caused by internal bodily diseases (atherosclerosis, endocrinopathies), but in practice they are classified as exogenous.
Can affective illnesses be considered a stable mental defect?
No. Affective disorders belong to a group of diseases (they have dynamics), whereas a mental defect (e.g., oligophrenia) is a persistent, non-processual state that arose after a stroke, trauma, or intoxication.
What is the main guideline when prescribing psychopharmacotherapy?
The prescription of any psychopharmacological agents is always carried out in strict accordance with the patient's leading syndrome identified.
