Delusions of parasitosis

Area of Science:

• Psychiatry
• Dermatology

Background:

• Delusions of parasitosis (DP) is a rare psychiatric disorder characterized by a fixed belief of parasitic infestation.
• Patients frequently present to emergency departments with somatic symptoms, particularly skin-related concerns.

Purpose of the Study:

• To highlight the diagnostic and treatment challenges of delusions of parasitosis in emergency settings.
• To discuss the management of patients with DP who may reject psychiatric referrals.

Main Methods:

• Diagnosis of DP is primarily based on patient history.
• Exclusion of organic skin disorders and other underlying mental or physical illnesses is crucial.
• Antipsychotic medications, specifically risperidone and olanzapine, are the recommended treatments.

Main Results:

• Patients with DP often reject psychiatric referrals, complicating management.
• The lack of health insurance among affected individuals presents significant barriers to obtaining necessary dermatologic and psychiatric consultations.
• Emergency physicians face diagnostic and treatment difficulties due to these challenges.

Conclusions:

• Effective management of DP in emergency departments is hindered by patient resistance to psychiatric care and socioeconomic factors.
• Multidisciplinary collaboration is essential for optimal patient outcomes.
• Further research into accessible and integrated treatment models for DP is warranted.
