prodrome
Pronunciation: PROH-drohm
An early symptom indicating the onset of a disease or disorder, particularly the period before full psychotic symptoms develop.
Full Definition
In psychiatric research, prodrome refers to the early warning signs and symptoms that precede the full manifestation of a mental health disorder, most commonly used in the context of psychosis. The prodromal phase of psychosis is characterized by subtle changes in perception, cognition, behavior, and social functioning that occur before the emergence of frank psychotic symptoms. These may include mild perceptual disturbances, suspiciousness, social withdrawal, cognitive difficulties, and functional decline. Prodromal symptoms are of particular interest in psychiatric research because they represent a potential window for early intervention that might prevent or delay the onset of full psychosis. Clinical high-risk or ultra-high-risk syndromes are operational definitions used to identify individuals in the prodromal phase for research and clinical purposes.
Usage
Usage note: Singular form; distinguish from 'prodromal' which is the adjective form.
