What are the details of the event that you think caused PTSD?

Schizophrenia is not a normal symptom of PTSD. Schizophrenia and PTSD can co-occur and co-exist. A drug injury could be a cause of Schizophrenia but it would not be the same as PTSD.

It is more likely that a head injury would cause Acute Stress Disorder. PTSD would require more complicated factors.

Besides, if the symptoms are treated, it does not matter what the specific diagnosis may be.
