Delusions are fixed beliefs that are not amenable to evidence-based challenge and that are inconsistent with the person's cultural and social background. They are a positive psychotic symptom occurring in schizophrenia, schizoaffective disorder, severe depression with psychotic features, bipolar disorder with psychosis, drug-induced psychosis, delirium, and some dementia presentations. Common types include persecutory delusions (being watched, followed, or harmed), grandiose delusions (having special powers or status), and referential delusions (believing communications are directed personally).

What lifestyle changes can help with delusions?

The priority is safety and accessing appropriate psychiatric care, not challenging the delusional content directly (which typically has no effect and can increase distress). Maintaining a calm, non-confrontational environment reduces agitation. Supporting the person to access psychiatric assessment is the most important step.

What integrative approaches support delusions?

Complementary approaches have no evidence-based role in treating delusions directly. They may support general wellbeing alongside psychiatric treatment. Family support and education, crisis support services, and community psychiatric nursing are the primary supports alongside medical treatment.

When should I seek professional support for delusions?

Seek psychiatric assessment — through doctor, crisis team, or A&E if necessary — for new or worsening delusions, particularly if accompanied by agitation, self-neglect, or any risk of harm to self or others. Delusions in an older person with new onset confusion require urgent assessment.

Recognition

Do any of these feel familiar?

Experiencing delusions is frightening — both for the person and for those around them. The person experiencing persecutory delusions lives in a genuinely threatening subjective reality. Family members watching someone they love develop delusional thinking often feel helpless and frightened. The critical issue is that this is a medical symptom — not a choice or a reflection of the person.
