disturbed

Disturbed is the past participle of disturb and functions as an English adjective meaning emotionally or mentally unsettled, troubled, or agitated. It can describe a person experiencing unease, a disruption to routine, or a situation that breaks calm. The term appears in everyday language in phrases such as “disturbed sleep” or “disturbed by events,” and it also occurs in literature and discourse to convey disruption or interference with order.

In clinical use, disturbed is a non-specific descriptor for symptoms rather than a diagnosis. Clinicians may note a “disturbed mood,” “disturbed sleep,” or “disturbed behavior” to indicate disruption requiring evaluation. Disturbance is the broader noun form. More precise categories include mood disorders, anxiety disorders, and trauma- or stressor-related conditions. Because “disturbed” expresses subjective assessment, its meaning can vary with context, culture, and the observer.

Disturbed is also the name of an American heavy metal band formed in Chicago in 1994. The core lineup consists of David Draiman (vocals), Dan Donegan (guitar), and Mike Wengren (drums); bassist changes led to John Moyer’s long tenure. The group broke through with The Sickness (2000), anchored by hits such as “Down with the Sickness” and “Stupify.” Their discography includes Believe (2002), Ten Thousand Fists (2005), Indestructible (2008), Immortalized (2015) featuring a cover of “The Sound of Silence,” Evolution (2018), and Divisive (2022). Disturbed is recognized as a prominent act in early 2000s metal and has maintained an active touring and recording schedule.
