What Causes Night Terrors?

Night terrors can have various causes, ranging in severity from 'minor' to 'very serious'.  Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.

Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose night terrors, we could:

  • Research the topic
  • Find a doctor with the time
  • Use a diagnostic computer system.
The process is the same, whichever method is used.

Step 1: List all Possible Causes

We begin by identifying the disease conditions which have "night terrors" as a symptom.  Here are six possibilities:
  • Alcohol Consequences
  • Depression
  • Stress
  • Lack Of Sleep
  • Restless Leg Syndrome
  • Anxiety

Step 2: Build a Symptom Checklist

We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
depression with some fatigue
no difficulty waking up
macrocytic red cells
absent sexual desire
high systolic blood pressure
major difficulty waking up
unsound sleep
loss of interest in activities
history of CFS diagnosis
restless legs at night
being a "night person"
... and more than 90 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of night terrors:
Cause Probability Status
Stress 90% Confirm
Alcohol Consequences 54% Possible
Lack Of Sleep 19% Unlikely
Depression 0% Ruled out
Anxiety 0% Ruled out
Restless Leg Syndrome 0% Ruled out
* This is a simple example to illustrate the process
