schizophrenia
• Anti-psychotic drugs that decrease dopamine activity lessen
schizophrenic symptoms
• Epigenetics:
• Study of chemical changes to a gene that influence its
expression
• (without altering DNA sequence)
• 1/200 genes of psychotic patients show epigenetic differences
• For genes involved in neurotransmission & brain development
• CAMH research
