Delusional Disorder is a mental health disorder where individuals experience one or more delusions, which they wholeheartedly believe is true when others know it is not. Common themes among delusions include believing someone famous is in love with them (erotomanic), an inflated sense of self-worth, power, or knowledge (grandiose), believing their partner is unfaithful (jealous), thinking that someone or something is spying on or trying to harm them (persecutory), believing that they have a medical concern or physical issue (somatic), or mixed disorders where more than one of the previous delusions are present. Rehab admission assessments typically include a full medical workup as well as an in-depth mental health assessment. Delusional disorder is often treated with a combination of medications and psychotherapy. Psychotherapy can have a significant role in achieving mental wellness. Individuals who are experiencing severe symptoms, or are at risk of harming themselves or others, may require a hospital admission for intensive support and stabilization services.
