Causes of Schizophrenia

The causes of Schizophrenia remain largely unknown.  All that can be said with any certainty thus far is that Schizophrenia likely has some genetic underpinnings, but that there needs to be some triggers in the environment to set-off whatever processes are controlled by these genes in order to make the condition manifest. 

Some of these environmental factors may include events that occur in pregnancy and around the time of birth, experiencing certain significant life stressors like child abuse, and using drugs like marijuana.

Once the illness gets triggered, there are likely changes in the brain and at the level of the neurotransmitters that cause the various symptoms of the disorder.
