Some dictionaries define hysteria as a neurological disease of uncontrolled emotions caused by excessive fear or joy. There are also those who say that it is possession by a spirit. This disease cannot be diagnosed through blood or urine tests, x-ray, etc. However, through a special form of treatment it may be determined as an element of ‘disturbance’ that causes the patient to speak nonsense, to undergo a voice change, to laugh, cry, wail, to have exceptional strength, red eyes, etc. How can it be treated and prevented? It is hoped that this book can provide the answers.
