The BrainDopamine- 6x as many
receptors, which intensifiespositive symptoms.
Ventricles are larger & they tend to have less gray matter.
Prenatal InfluencesIf the mom-to-be:
Lives in a country with a flu epidemic Gave birth in the months following
fall-winter flu season Experiences the flu Lives a highly populated area
Then: There’s a higher risk to the child for
schizophrenia.
Genetics EnvironmentalNormally: 1 in 100Parent/sibling: 1

lying, stealing, displaying, unrestrained sexual behaviors.

fearless approach to life, have lower levels of stress or anxiety, reduced activity or tissue in the frontal lobe.
2 Main Factors: childhood mal-treatment & a gene that alters theneurotransmitter balance. Some are predisposed to be more sensitive to maltreatment.
Predictors
