Brief summary

The high hereditary component and the contribution of neurodevelopmental processes in bipolar disorder and schizophrenia means implies the children of these patients are considered a high risk population for both diseases and therefore a very adequate sample for the study of vulnerability markers to both disorders. To date there is no previous literature on the psychological approach of children and adolescents of bipolar or schizophrenic patients. The concept of cognitive reserve (CR) was initially developed in the field of dementia, it assumes that people with the same brain damage may have different clinical manifestations depending on their ability to compensate for this damage, so a greater cognitive reserve will entail a greater capacity to compensate the alterations and difficulties due to the pathology. Enhancing CR in high genetic risk population could help the acquisition of skills that help compensate the clinical, cognitive and neuroimaging alterations and ultimately help in the prevention of the development of pathologies for those with higher risk.This study aims to develop and apply a psychological program in order to enhance cognitive reserve (CR) in child, adolescent and young adults offspring of patients diagnosed with schizophrenia or bipolar disorder (SZBP-OFF).

Detailed description

The project will have two main objectives: to test the effectiveness of the psychological program and to test if the observed improvements are stable over time (nine months of follow-up). A sample of 108 SZBP-OFF and 52 community controls will be included. Both groups will be assessed with clinical scales, neuropsychological, CR and neuroimaging assessments at baseline. Then, the SZBP-OFF group will be randomized to psychological program to enhance CR (N= 54) or to support treatment (N=54). SZBP-OFF subjects will be evaluated with clinical, CR, neuropsychological and neuroimaging tests after the psychological intervention and at nine months follow-up in order to assess if the obtained results are stable over time. The investigators hypothesize that SZBP-OFF will show lower CR scores and higher percentages of psychopathology, cognitive difficulties and brain abnormalities. The investigators also hypothesize that SZBP-OFF who received the psychological intervention will increase their CR and will decrease the severity of the observed difficulties (in clinical, neuropsychological, CR and neuroimaging areas). These results will be stable in the nine month follow-up assessment.

Interventions

The intervention is aimed at improving cognitive reserve in offsprings of patients diagnosed with schizophrenia or bipolar disorder. The program is composed of 12 sessions of 60 minutes and will be adapted according the three different age groups (6-12) (13-18) (18-25). Each group will include between 6-to-8 offsprings and conducted by 4 experienced neuropsychologists in both children and adults. The sessions are the following:

BEHAVIORALSupport intervention

The support group will schedule meetings with the participants in order to talk about their daily life with the possibility to talk about the difficulties they encounter.

Design outcomes

Primary

MeasureTime frameDescription
Cognitive reserve3 months afther the intervention and 12 months after baselineChanges in cognitive reserve assessed with a specific scale which assesses the most common proposed proxy indicators such as education-occupation' which is assessed taking into account the number of years of obligatory education that subjects completed and parent's educational level; and the lifetime school performance and lifetime participation in leisure, social and physical activities.

Secondary

MeasureTime frameDescription
Young Mania Rating Scale (YMRS)After the intervention (3 months) and 1 year after baselineThe YMRS is a rating scale used to evaluate manic symptoms at baseline and over time in individuals with mania. Scores superior to 12 indicate presence of manic episodes. Higher scores indicate more severe mania.
Bipolar Prodrome Symptom Interview and Scale_Prospective (BPSS_FP)12 months after baselineIt is a specific interview for emerging bipolar disorder symptoms.
Continuous Performance TestAfter the intervention (3 months) and 12 months after baselineSustained attention test
Hamilton Depression Rating Scale (HDRS-21)After the intervention (3 months) and 1 year after baselineScale to assess depression symptoms. Score between 0 to 7 indicates absence of depressive symptoms, hihher scores indicate more severe depression.
Stroop TestAfter the intervention (3 months) and 12 months after baselineExecutive function test (inhibit interference)
Neuroimage variablesAfter the intervention (3 months)Changes in white and grey matter. Measure will be performed with a MRI
Wisconsin Card Sorting TestAfter the intervention (3 months) and 12 months after baselineExecutive function test (set-shifting, flexibility)
