Did You Know Brain Fog Might Point to POTS, Not Just Stress?

 When you're feeling mentally clouded, forgetful, or constantly tired, it's easy to blame it on stress, poor sleep, or overworking. But what if your "brain fog" is actually a sign of something deeper, like POTS?

Postural Orthostatic Tachycardia Syndrome (POTS) is a form of autonomic dysfunction that affects thousands, yet often goes undiagnosed. One of its most misunderstood symptoms? Brain fog — a frustrating mental haze that makes it hard to concentrate, remember, or think clearly.

What Exactly Is Brain Fog in POTS?

Unlike occasional forgetfulness, POTS-related brain fog is persistent and can intensify when standing up, during physical activity, or after a large meal. It’s not just “in your head.” It's a neurological response to the body struggling with blood flow, oxygen delivery, and heart rate regulation.

Common symptoms include:

  • Memory lapses

  • Trouble focusing

  • Feeling detached or disoriented

  • Difficulty processing conversations

These symptoms often go hand-in-hand with chronic fatigue, dizziness, rapid heart rate, and exercise intolerance — all hallmark signs of POTS.

Why So Many People Misdiagnose It as Anxiety or Burnout

Because brain fog overlaps with symptoms of stress and anxiety, many patients, especially young women, are misdiagnosed or dismissed. Some are told it's “just hormones” or “mental exhaustion,” delaying proper diagnosis and treatment.

The truth is: If you're experiencing brain fog, heart palpitations, and fatigue upon standing, it’s worth asking your doctor to evaluate you for POTS.

The Importance of Autonomic Testing

POTS can be diagnosed through tilt table testing and a thorough review of symptoms. At The Heartbeat Clinic, we specialize in autonomic nervous system testing and holistic POTS care — helping patients understand the root cause of their symptoms.

Take Control of Your Health

If brain fog is disrupting your daily life, don’t settle for vague answers. Seek care from specialists who understand how POTS affects the brain, nervous system, and heart. With proper diagnosis and a tailored treatment plan, many patients see significant improvement.
