Concept
Neurosis
Summary
Neurosis (: neuroses) is a term mainly used today by followers of Freudian thinking to describe mental disorders caused by past anxiety, often that has been repressed. In recent history, the term has been used to refer to anxiety-related conditions more generally.
The term "neurosis" is no longer used in condition names or categories by the World Health Organization's International Classification of Diseases (ICD) or the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM). According to the American Heritage Medical Dictionary of 2007, the term is "no longer used in psychiatric diagnosis".
Neurosis is distinguished from psychosis, which refers to a loss of touch with reality. Its descendant term, neuroticism, refers to a personality trait of being prone to anxiousness and mental collapse. The term "neuroticism" is also no longer used for DSM or ICD conditions; however, it is a common name for one of the Big Five personality traits. A similar concept is included in the ICD-11 as the condition "negative affectivity".
The term neurosis was coined by Scottish doctor William Cullen to refer to "disorders of sense and motion" caused by a "general affection of the nervous system". The term is derived from the Greek word neuron (νεῦρον, 'nerve') and the suffix -osis (-ωσις, 'diseased' or 'abnormal condition'). It was first used in print in Cullen's System of Nosology, first published in Latin in 1769.
Cullen used the term to describe various nervous disorders and symptoms that could not be explained physiologically. Physical features, however, were almost inevitably present, and physical diagnostic tests, such as exaggerated knee-jerks, loss of the gag reflex and dermatographia, were used into the 20th century.
French psychiatrist Phillipe Pinnel's Nosographie philosophique ou La méthode de l'analyse appliquée à la médecine (1798) was greatly inspired by Cullen. It divided medical conditions into five categories, with one being "neurosis".
