Abstract
In the recent study by Verhoeven and Egger, 2015 and the recent letter to the editor
by Boot et al. 2015 an emphasis is given to the best possible pharmacological treatment
of 22q11-2 Deletion-Syndrome related psychoses. We would like to present the case
of a 23-year old Cypriot patient with 22q11.2 deletion syndrome who fulfilled criteria
for treatment resistant schizophrenia (TRS). He was sequentially treated with aripiprazole,
risperidone, olanzapine, haloperidol and a combination treatment with olanzapine and
haloperidol. Clozapine was the only antipsychotic medication that has improved his
condition.
