Key findings (2004)

1. Early-onset schizophrenia is associated with significantly increased visuospatial memory retrieval deficits compared to age- and gender- matched healthy control participants
   
   
2. Early-onset schizophrenia is associated with significantly increased fine and gross motor movements in both emotionally neutral and emotionally charged interpersonal contexts compared to age- and gender- matched healthy control participants

Key Findings (2005)

1. Early-onset schizophrenia, primarily of the undifferentiated type, is associated with encoding deficits that contribute to the retrieval deficits
   
   
2. Early-onset schizophrenia, primarily of the undifferentiated type, is associated with prominent 'thought blocking': this formal thought disorder symptom is associated with considerable distress for the young people experiencing it and their parents (Pearson's r = 0.7).
   

Key findings (2006)

1. Early onset bipolar disorder is phenotypically the same as adult onset bipolar disorder.
   
   
2. Early onset schizophrenia is associated with qualitatively similar visuospatial memory deficits in children, adolescents and adults.
   
   

Key findings (2007)

1. Early onset 'rapid cycling' bipolar disorder is qualitatively and quantitatively similar to ADHD, combined type and comorbid dysthymic disorder
   
   
2. Early onset schizophrenia is associated with qualitatively similar visuospatial working memory deficits in children, adolescents and adults.
