Cognitive Impairment

January 28, 2015


Cognitive impairment can deeply affect your way of living from disrupting your concentration to making everyday decisions.


Cognitive Impairment is when a person has trouble remembering, learning new things, concentrating, or making decisions that affect their everyday life. Cases can range from mild to severe.


A study by the University of California compared 105 women ages 65 and older with sleep-disordered breathing to 193 women who did not have the condition. Five years later, the women with sleep-disorded breathing had an increased risk of developing cognitive impairment.  In particular, hypoxia (refers to an inadequate oxygen supply to the cells and tissues of the body) seemed to be the factor that led to the increased risk. Treatment for hypoxia with a CPAP machine can slow or reverse cognitive impairment.  More studies are pending.



Consistent or increasing concern about your mental performance may suggest mild cognitive impairment (MCI). Cognitive issues may go beyond what’s expected and indicate possible MCI if you experience any or all of the following:

  • You forget things more often.
  • You forget important events such as appointments or social engagements.
  • You lose your train of thought or the thread of conversations, books or movies.
  • You feel increasingly overwhelmed by making decisions, planning steps to accomplish a task or interpreting instructions.
  • You start to have trouble finding your way around familiar environments.
  • You become more impulsive or show increasingly poor judgment.
  • Your family and friends notice any of these changes.

If you have MCI, you may also experience:

  • Depression
  • Irritability and aggression
  • Anxiety
  • Apathy
