as "brain fog")

-Inability to tolerate changes in temperature

-Decreased sweating or excessive sweating

-Abnormal deep tendon reflexes may or may not be present.

Less frequently recognized signs and symptoms:

irregardless of amount or quality of sleep.

-Central sleep apnea

-Need to sleep 12-14 hours in order to complete simple activities of

daily living.

-Anoxic or convulsive seizures that are not epileptic.

-Frequent need to urinate at night.

-Upon standing feels head is "heavy". This resolves with lying down

or with walking around.

-Decrease in (or absence of) lubricating tears in the eye.

-Sensitivity to bright, florescent light and bright sunlight. Many patients report feeling pre-syncopal in large grocery stores and

department stores that use excessive florescent lighting. Flashing

lights and multi-colored lighting can also produce symptoms.

-Visual distortion: Television screens and computer screens can

appear distorted, especially post-syncopal or pre-syncopal episode.

Flat screens are recommended.

-Distorted depth perception resulting in a feeling of unsteadiness.

Often appears to be "clumsy" or excessively cautious when climbing

stairs, reaching for an object, etc.

-Other visual disturbances include a graying out or blacking out of

the visual field; either partially or completely.

-Decreased awareness of what is in the peripheral visual field. This

often causes the patient to startle because they did not perceive

anyone or anything next to them.

-Frequent "bumping into things". Attributed to a combination of

visual and depth perception deficits.

-Noise sensitivity. Loud or beating sounds can cause pre-syncopal

episodes. Difficulty filtering out sounds. Easily distracted by


-Sensitivity to odors, even pleasant smelling chemicals such as

perfume. Odors such as cleaning products, gasoline, strong foods,

-Severe constipation and decreased gut motility.

-Weight gain irregardless of diet modifications.

-Overall slowing of metabolism is common. -Increased metabolism (rare)

-Excessive gut motility leading to chronic diarrhea and weight loss.

(less common)

-Sensitivity to touch. Mild pat on the arm or squeeze of the hand can

cause excruciating pain especially right after an episode or if the

patient has not had enough sleep.

-Decrease sensitivity to pain/touch in certain areas. If standing or

sitting too long causes hands and feet to turn cold and blue, patient

will have decreased sensation in these areas due to poor blood flow.

-Taste and appetite changes. Fruits and other acidic foods may taste

extremely acidic. Foods may taste differently if patient is tired,

stressed, or post-syncopal episode.

-Hair loss due to decreased blood supply to hair folicles.

-Speech disturbances: Inability to finish an expressed thought, loss

of train of thought, "spoonerisms", especially if up and about for 2

hours or more without lying flat and resting.

by sitting or standing too long. Usually resolves if patient lies


-Drifting to the right or left when walking. Most commonly patients

report drifting to the left. Many patients report always fainting to

the left as well. Appears to be unrelated to hand-dominance, but

further research is needed.

test positive for the disease. This includes hypermobile joints,

double joints, and soft, velvet-like skin that has little or no


-Often has another auto-immune disorder.
