When Your Brain Feels Cloudy: Understanding POTS-Related Brain Fog
Brain fog or cognitive dysfunction, where your ability to think feels cloudy or slowed down, is a common symptom of postural orthostatic tachycardia syndrome (POTS).
In POTS, brain fog often worsens with prolonged standing or being upright, as reduced blood flow to the brain can impair concentration and mental clarity. However, research shows that cognitive symptoms can still be debilitating even when sitting or lying down. Similarly, many other POTS symptoms are not limited to upright positions—they can persist regardless of posture.
Here’s a few different ways people tend to describe brain fog associated with POTS:
Difficulty processing info
“Fuzzy” sensation in head
Losing train of thought
Trouble multitasking
Memory issues
“Hazy” sensation in head
Thinking slowly
Limited ability to work
Difficulty focusing
Feeling confused
School performance issues
Feeling “cloudy”
Mental fatigue/exhaustion
Trouble thinking
Forgetfulness
Feeling easily distracted
Mind going “blank”
Feeling “in a daze”
Difficulty finding words
Feeling scattered
If you’re experiencing these symptoms, you’re not alone—and it’s not all in your head. Brain fog in POTS is real, frustrating, and often misunderstood, but with the right support and strategies, it can become more manageable.
