Behandelter

Behandelter is a German noun derived from the verb behandeln, meaning to treat. In medical and clinical contexts, Behandelter denotes a person who has received treatment—the treated one. It is used to refer to a patient or study subject who has undergone a therapy or procedure, often in case reports, clinical studies, and regulatory documents.

Grammatically, Behandelter is the masculine singular nominative form; Behandelte is the feminine singular; Behandelten is the plural (used for all genders). The term functions as a nominalized participle and can appear in various cases and numbers, depending on sentence structure.

Usage notes: Although still found in some formal medical texts, Behandelter is less common in everyday language, where Patient or Behandlungsteilnehmer is more typical. It is primarily a label indicating treatment status rather than providing clinical detail about the person.

In practice, Behandelter contrasts with Behandler (the practitioner or clinician) and with Behandlung (the treatment). The term may appear in comparative contexts, for example in trial reporting as “der Behandelte” versus “der Placebo-Behandelte.”

Example: Der Behandelte zeigte eine Besserung nach der Therapie. Die Behandelten wurden randomisiert der Behandlungsgruppe zugeteilt.
