molecule may underpin the psychotic symptoms of schizophrenia, a mouse study
suggests. A better understanding of the roots of the disease and new
antipsychotic medications may follow. Schizophrenia affects 24 million people
worldwide. Sufferers experience disrupted thoughts and behaviour, and sometimes
delusions. Its cause is uncertain, but faulty brain chemistry is thought to be
key. Three main chemical messengers, called neurotransmitters, are implicated.
Different researchers tend to favour one molecule the others as the disease's
root cause. Schizophrenia a complex disease that affects the brain's chemistry
and structure, says Carol Tamminga from the University of Texas, Dallas, who
studies the disorder. "The next step is to work out how a molecular change like
this translates into hallucinations and delusions," she
says.</DIV></BODY></HTML>
