neurosis
UK: njʊəˈrəʊsɪs | US: nʊˈroʊsɪs
n. A mental or emotional disorder characterized by anxiety, obsessive thoughts, or compulsive behaviors, typically without loss of contact with reality.
The word "neurosis" originates from Greek, combining "neuron" (nerve) and "-osis" (a suffix indicating a pathological or abnormal state). Initially coined in the 18th century by Scottish physician William Cullen, it described nervous system disorders. Over time, its meaning shifted to focus on psychological distress rather than purely physical symptoms. The morphemes reflect this evolution: "neuro" anchors the term in the nervous system, while "-osis" signals dysfunction.
Chronic anxiety may develop into a neurosis if left untreated.
Freud pioneered the study of neurosis as a psychological phenomenon.
Her compulsive behaviors were diagnosed as a mild neurosis.
Modern therapy often addresses neurosis through cognitive techniques.
The term "neurosis" is less commonly used in clinical psychology today.
