Psychiatric Disorders • Substance abuse complicates many psychiatric conditions, and may be the primary cause of others. Psychiatric Disorders • Important to exclude medical causes of behavioral problems before concluding they are psychiatric. Psychiatric Disorders • Not so important to classify a patient’s psychiatric condition as it is to recognize patterns that may put the patient or others at risk. Remember, sometimes the only difference between us and them is the fact that we have the keys! Psychiatric Emergencies Understanding Psychiatric Emergencies
