Abstract
Introduction Delusions, a core symptom of psychosis, are false beliefs that are rigidly held with
strong conviction despite contradictory evidence. Persistent delusions if held for
more than 1 month lead to the diagnosis of delusional disorder (DD) as per the Diagnostic
and Statistical Manual of Mental Disorders-5. Very sparse literature is available
evaluating the utility of individualised homoeopathic medicine in this condition.
Materials and Methods A 60-year-old man presenting with symptoms of DD was treated during the period of
February 2020 to February 2021. Individualised homoeopathic medicine was prescribed.
Outcomes were assessed using Psychotic Symptom Rating Scales. Modified Naranjo Criteria was used to assess whether the changes were likely to be associated with the homoeopathic
intervention.
Results A beneficial result was obtained from Individualised homoeopathic treatment.
Conclusion Even though this is a single case report, the recovery of the patient from the suspiciousness
is remarkable and there is no relapse of the symptoms. The patient's family life is
peaceful now and he was able to rejoin his job.
