Background:

Delusional infestation, a form of monodelusional disorder, is encountered in psychiatric and primary care.
Good outcomes are achievable with patient compliance.

Purpose of the Study:

To report on a series of 50 consecutive cases of delusional infestation.
To evaluate the effectiveness of second-generation antipsychotics in treating this condition.

Main Methods:

A retrospective case series of 50 patients diagnosed with delusional infestation.
Pharmacotherapy utilizing second-generation antipsychotics was the primary treatment modality.

Main Results:

The majority of cases (94%) had an insidious onset with symptom duration of 6 months or more.
Common presentations included delusions of insects on the body (28 cases) or scalp (20 cases).
68% of patients achieved complete remission with second-generation antipsychotics, 26% showed partial improvement, and 6% did not respond.

Conclusions:

Second-generation antipsychotics demonstrate significant utility in treating delusional infestation.
Further research is needed to fully understand the treatment and long-term outcomes of this psychiatric disorder.
