Neuroprotective Effects of Risperdal on Brain and Cognition in 22q11 Deletion Syndrome

Start date: September 29, 2017
Phase: N/A
Study type: Interventional

Chromosome 22q11.2 deletion syndrome (22q11DS) is a neurogenetic condition associated with a high risk of psychiatric disorders, including schizophrenia spectrum disorders. This population is characterized by a particular neurocognitive profile and atypical brain development. Risperidone is a second-generation antipsychotic, inhibitor of dopaminergic receptors. Used in the treatment of psychosis, risperidone is frequently prescribed in 22q11DS, for example to treat a psychotic episode. Research on an animal model of 22q11DS (LgDel+/- mice) shows that administering an antipsychotic for 12 days during a critical period of brain development (adolescence) prevents deleterious neuronal changes and improves behavioral performance in mice. The aim of this study is therefore to replicate the results found in mice and to identify a long-term neuroprotective effect. This study is inspired on the one hand by the families who share with us the difficulties of individuals affected by 22q11DS on a daily basis, but also by the encouraging results of studies conducted on mice.

Social Cognition Training and Cognitive Remediation

RCKID
Start date: October 11, 2017
Phase: N/A
Study type: Interventional

Social cognition refers to mental operations that enable people to perceive, interpret constantly changing social informations. These processes allow people to rapidly, effortlessly and flexibly perceive and interpret rapidly-changing social information, and respond appropriately to social stimuli. Besides, this ability gives meaning to the actions of others. Impairments in this field may largely underlie social dysfunctions and reduce adaptive skills. Moreover, social cognitive disabilities contribute more or less directly to behavioral disturbances and psychiatric symptoms The "RC KID" program involves a variety of exercises in a paper and/or pencil or a computerized format or role playing and a strategy coaching approach. "RC KID" targets the emotion recognition and social interaction. A little cartoon character (a pirate), is supposed to be very friendly and kind toward children. The pirate will accompany them throughout the program for an effective and positive reinforcement. The main goal of "RC KID" is to adjust to children's difficulties in daily life. Moreover, since the cognitive remediation benefit is complex to apply in daily life, the program is based on a metacognitive strategy. After a complete neuropsychological assessment and a psychoeducational session (with the child and the parents), 16 1-h-sessions of cognitive remediation with the therapist are proposed. Each session is composed of three parts: (1) computerized tasks focusing on specific emotion recognition components (20 min). RC KID is composed of 2 modules : Emotion recognition and social interaction. These tasks contain photo or video. (2) pen and paper or role playing tasks focusing on the same processes (20 min) (3) a proposal of a home-based task (during 20 min). Weekly, home tasks are proposed to the child and analyzed with the parents and the therapist. Indeed, home exercises are useful to promote the transfer of strategies to daily life and their subsequent automation. The heterogeneity of cognitive deficits in 22q11.2 deletion necessitates an individualized cognitive remediation therapy. In this regard, "RC KID" seems to be a promising tool.
