Diagnosis Checklist: Questions your doctor may ask (and why!)

During a consultation, your doctor will use various techniques in their assessment of Laughter. Your doctor may ask several questions when assessing your condition. It is important to remember that your consultation is a two-way process and any extra information you can share with your doctor about your symptoms may help them with their diagnosis. Some of the questions your doctor may ask are listed below:

  • How long has the excessive or inappropriate laughter been present? - to determine if acute or chronic.
  • Is there an obvious explanation for laughter? - Remember that it is possible to have laughter for rational non-medical reasons e.g. normal happy personality.
  • Past psychiatric history? - e.g. bipolar affective disorder is a recurrent disorder characterized by episodes of mania and depression. The periods of mania include symptoms of elevated mood (euphoria) sometimes accompanied by excessive or inappropriate laughter; social anxiety may be associated with "nervous laughter" .
  • Risk factors for stroke? - e.g. high blood pressure, high cholesterol, diabetes, smoking, family history, history of transient ischemic attacks - can assess risk of multi-infarct dementia - a feature of multi-infarct dementia may be inappropriate laughing.
  • Illicit drug history? - e.g. cocaine may provide a feeling of euphoria and excitement and cause excessive or inappropriate laughter; amphetamines, ecstasy and cannabis intoxication may provide a feeling of euphoria with a feeling of superiority and general feeling of wellness and cause excessive or inappropriate laughter.
