Morgellons, Somatoform Disorder, and Delusional Infestation
People with somatic disorders tend to by hyper-aware of normal body sensations -- and they tend to interpret these sensations as medical illness. This stress has real physical effects on the body and leads to a spiral of worsening physical symptoms and psychological health. Psychotherapy is far more likely to be successful than medication in breaking this cycle.
Pearson and colleagues suggest that since they cannot find a common cause of Morgellons disease, patients should get "standard therapies for co-existing medical conditions and/or those recommended for similar conditions such as delusional infestation."
Patients who are convinced they are infested with parasites often respond to treatment with antidepressant or antipsychotic medication.
