Schizophrenia - Early Symptoms
Professor Pat Levitt explains that while schizophrenia is rarely seen in childhood, there are early signs of developmental problems.
We know that schizophrenia has been defined previously as when a person comes into the hospital exhibiting what we focus on in schizophrenia, which is the psychosis. We know that there are differences (they may be subtle differences) earlier on. The ability to perform certain cognitive functions, learning and memory may be altered. There are differences in motor coordination that people have identified. Itâ€™s important to realize that theyâ€™re very subtle and itâ€™s not that theyâ€™re unique to schizophrenia but there is an indication that even before the major issues of psychosis arise, which typically occurs in the twenties, that there are fundamental changes that are occurring. Now the second part of the question is why donâ€™t you see anything early on in childhood if gene vulnerability is causing, at least in part, the disorder? Well first of all we know that there are actually childhood onset examples of schizophrenia, although itâ€™s rare. And we also know that gene vulnerability may not be read out, we may not see anything obvious in changes until after puberty. We really donâ€™t understand why thatâ€™s the case but we know that it exists both in research models - animal models as well as in humans as well. Thereâ€™s something magical about this developmental period but we donâ€™t understand why.

1225. Schizophrenia - Genetic Vulnerability
Professor Pat Levitt comments that people with genetic vulnerability to schizophrenia often have developmental problems from an early age.
1222. Autism - Early Diagnosis
Professor Pat Levitt explains that the sooner autism is diagnosed, the more effective the intervention.
914. Reelin (RELN) Gene
Reelin is a gene that is important to learning and memory. It is also a candidate gene for autism, schizophrenia, and Alzheimer's disease.
819. Schizophrenia in Childhood
Professor James Watson explains that although schizophrenia is rarely diagnosed before adolescence, abnormalities may exist from an early age.
1226. Toxic Stress
Professor Pat Levitt defines toxic stress, a term used by neurobiologists to describe negative experiences that can affect brain development.
1223. Genes and Schizophrenia
Professor Pat Levitt discusses that although it shares genes with other disorders, schizophrenia is likely caused by unique combinations of genes.

A review of the causes, symptoms, and treatments of schizophrenia.
1254. Schizophrenia - Motor Control
Professor David Lewis explains that schizophrenic individuals can have coordination problems, which may relate to impaired neural circuits.
832. White Matters
Only quite recently have neuroscientists begun to understand the importance of white matter, a long-neglected part of the brain.

Networks are the engines that drive our brain, they exist at every level of organization. Genes, proteins, and neurons all form highly integrated complex networks.
