Family Medicine

The National Institute of Mental Health reports that some people addicted to drugs display similar behaviors as those with schizophrenia. For this reason, doctors often screen for drug and alcohol abuse when diagnosing schizophrenia. Symptoms of drug abuse that may mirror symptoms of schizophrenia include:

having a dirty, unkempt appearance
withdrawing from friends, social engagements, work or school
odd or drastic changes in behavior, including aggressive behavior
poor concentration
delusions, hallucinations, and paranoia
changes in speech
memory problems
confusion
tremors

Doctors should also be aware that substance abuse problems are more common in people with schizophrenia. Further, some drugs may increase the symptoms of schizophrenia in people with the disease.
