POTS PATIENTS WITH BRAIN FOG HAVE NEUROCOGNITIVE DEFICITS
Individuals with POTS, or postural orthostatic tachycardia syndrome, often complain of cognitive problems, like the inability to focus, difficulty concentrating and forgetfulness. These cognitive symptoms are often referred to as “brain fog” and are commonly seen in POTS patients and other illnesses, including Lyme disease.
A recent study by Wells and colleagues ¹ confirms findings from previous studies which demonstrated that POTS patients with brain fog have impaired short-term memory and diminished alertness.
POTS is characterized by a substantial increase in heart rate and sometimes a drop in blood pressure when the individual stands up. This can cause lightheadedness, heart palpitations and in some cases, a loss of consciousness.
The authors measured short-term memory problems and alertness in 11 POTS patients with brain fog using neurocognitive testing and compared them with 8 healthy controls.
They found that “POTS patients demonstrated significantly longer latency in delayed match to sample response time and greater errors in attention switching task.”
While previous studies have shown neurocognitive deficits in POTS patients with evidence of impaired cerebral blood flow, Wells and colleagues report that such deficits can occur in patients with POTS “even in the absence of impaired cerebral blood flow.”
Editor’s note: I have seen individuals with Lyme disease who suffer from “brain fog” and POTS. I would appreciate a study to determine how often brain fog occurs in Lyme disease patients presenting with POTS.

Great example of how Dr. Fauci’s “Big Science” has continued to fail Lyme/MSIDS patients. We either don’t have any studies OR we have studies that are rigged for a predetermined outcome. They utilize flawed testing and severely narrow entrance criteria leaving out the sickest patients.
The “Eye or Mordor” has swung to COVID, meanwhile people are still becoming infected with tick-borne illnesess that will be misdiagnosed or undiagnosed. Even IF they manage to test positive, they will be treated with the unscientific and antiquated mono therapy of 21 days of doxycycline – no matter what their symptoms are and if they are coinfected with other pathogens.
Lyme/MSIDS patients, after 40 years, continue to be caught in a Catch-22.
