Insights

Morgellons disease, characterized by skin fibers, is best explained by a psychiatric etiology. Treatment with antipsychotic medication is supported by current evidence after excluding other causes.

Area of Science:

  • Dermatology
  • Psychiatry
  • Infectious Diseases

Background:

  • Morgellons disease presents with skin fibers, with debated infectious or psychiatric causes.
  • Current treatment guidelines for Morgellons disease are not well-defined.

Purpose of the Study:

  • To evaluate existing evidence on the etiology and treatment of Morgellons disease.
  • To inform clinical management strategies for patients with Morgellons disease.

Main Methods:

  • A comprehensive PubMed search was conducted using keywords related to Morgellons disease and delusional infestation.
  • Original research articles published from January 2010 onwards, focusing on etiology and treatment, were reviewed.

Main Results:

  • Sixteen articles on etiology showed correlative data, with stronger support for a psychiatric origin than an infectious one.
  • Eleven articles on treatment indicated that antipsychotic regimens have the most evidence of efficacy.

Conclusions:

  • Current evidence suggests Morgellons disease has a psychiatric etiology.
  • Treatment with low-dose antipsychotic agents is recommended after excluding non-psychiatric causes.
