Inappropriate Emotions & Actions A schizophrenic person may laugh at the news of someone dying or show no emotion at all (apathy). Patients with schizophrenia may continually rub an arm, rock a chair, or remain motionless for hours (catatonia). 7 Positive and Negative
Symptoms Schizophrenics have inappropriate symptoms (hallucinations, disorganized thinking, deluded ways) that are not present in normal individuals (positive symptoms). Schizophrenics also have an absence of appropriate symptoms (apathy, expressionless faces, rigid bodies) that are present in normal individuals (negative symptoms). 8 Chronic and Acute
Schizophrenia When schizophrenia is slow to develop (chronic/process) recovery is doubtful. Such schizophrenics usually display negative symptoms. When schizophrenia rapidly develops (acute/reactive) recovery is better. Such schizophrenics usually show positive symptoms. 9 Subtypes 10

Rapport, National Institute of Mental Health Brain scans show abnormal activity in the frontal cortex, thalamus, and amygdala of schizophrenic patients. Adolescent schizophrenic patients also have brain lesions. 12 Abnormal Brain Morphology Schizophrenia patients may exhibit
