Sleep disorders can be caused by various factors, including:

  1. Traumatic brain injury or stroke: More than half of individuals who have experienced a traumatic brain injury or stroke will develop sleep problems.
  2. Parkinson’s and Alzheimer’s disease: Sleep disturbances are common in individuals with neurological conditions like Parkinson’s and Alzheimer’s disease.
  3. Obesity: Being overweight or obese increases the risk of developing sleep apnea, a sleep disorder characterized by interrupted breathing during sleep, as well as the risk of stroke.
  4. Spinal cord injury: Sleep problems can also occur after a spinal cord injury.
  5. Chronic medical conditions: Conditions such as diabetes, asthma, and heart disease can contribute to the development of sleep disorders.
  6. Hormonal changes: Hormonal fluctuations that occur during menopause and pregnancy can disrupt sleep patterns.
  7. Environmental factors: Shift work, long-distance travel across multiple time zones, and exposure to excessive noise or light can all affect sleep quality.
  8. Psychological disorders: Mental health conditions like depression, anxiety disorders, post-traumatic stress disorder (PTSD), and schizophrenia spectrum disorders can disrupt normal sleep patterns.
  9. Medications and substances: Certain medications, such as antidepressants or stimulants, as well as the use of alcohol or drugs, can interfere with healthy sleep.
  10. Sleep deprivation and lifestyle factors: Chronic lack of adequate sleep due to poor sleep habits or a busy lifestyle can lead to the development of various sleep disorders.

Symptoms indicating Sleep Disorders
