Aims: Longitudinal description of a clinical case of a woman with Chromosome 22 deletion syndrome (22q11.2DS), mild intellectual disability (ID) and associated psychiatric disorders, treated at "Adolescent Outpatient Service", at the ASST Monza DSMD from 2011 to 2017.
Methods: Assessment Test Tools. T0 (2011): WAIS-R; SCID-I; Vineland Scale; SPAIDD-G; SPAIDD-Follow-up. T1 (2013): SPAIDD-Follow-up. T2 (2015): SPAIDD-Follow-up. T3 (2017): SCID-I; Vineland Scale; SPAIDD-Follow up. Pharmacological psychiatric treatment: Shift from haloperidol 1 mg, sertraline 100 mg to aripiprazole 15 mg, venlafaxine 150 mg. Psychoeducational psychological treatment: 1 session every 15 days; support to family.
Results: (2011) WAIS-R: slight ID (total IQ 67, verbal IQ 73, performance IQ 67); SCID-I: subthreshold psychotic symptomatology, panic attack disorder with agoraphobia, obsessive-compulsive disorder (OCD) with trichotillomania; Vineland Scale: Communication 256/266, Daily Skills 267/402, Socialization 202/268, Motor skills 111/144; SPAIDD-G: OCD; SPAIDD-Follow up: aggression, psychomotor agitation, somatic complaints, impulsivity, oppositional behaviour, stereotypes, depressed mood, compulsions. (2017) SCID-I: OCD with trichotillomania; Vineland Scale: Communication 248/266, Daily Skills 312/402, Socialization 226/268, Motor skills 136/144; SPAIDD-Follow-up: stereotypes and compulsions persist.
Discussion and conclusions: There was no transition to psychosis in the follow-up; OCD and trichotillomania persists, probably related to neurodevelopmental alterations, that are difficult to be modified. In 22q11.2DS patients, standard non-pharmacological treatment strategies (CBT) are difficult to apply, but in the present case the combination of pharmacological and psychoeducational psychological treatment was effective, both for the reduction of symptoms and for the acceptance of ID by patient and family.
