Some of the listed symptoms are always present while others
occur
when a person with Autonomic Dysfunction has been standing or sitting too long:
-Dizziness
-Lightheadedness
-Vertigo (room spinning or the sensation of spinning)
-Feeling faint (pre-syncope)
-Fainting (syncope)
-Chest pain or pressure
-Excessive fatigue

-Retching
-Exercise Intolerance: becoming short of breath on mild exertion,
having
chest pain or palpitations on mild exertion. Having excessive
heart rate during or immediately after exercise. Leg cramps
or
numbness of arms and legs during or after mild exercise.
-Visible pooling in arms and legs: Deep purple-red color in fingers
and
toes.
-White appearance of fingers. Some present with white patches of skin
on
arms and legs.
-Extremely cold hands and feet.
-Numbness of hands and feet.
-Muscle weakness
-Muscle and joint pain
-Tremors or mild shaking of hands
-Frequent headaches or migraine headaches
-Irritability due to decreased blood flow to the brain
-Feeling anxious/Having panic attacks due to increased production of
adrenaline
-Mood changes
-Forgetfullness
-Inability to concentrate or remember (frequently referred to
as "brain
fog")
-Inability to tolerate changes in temperature
-Decreased sweating or excessive sweating
-Abnormal deep tendon reflexes may or may not be present.
-Basic neurological exam is normal.
-Intelligence normal when receiving adequate cerebral perfusion.
Less frequently recognized signs and symptoms:
-Insomnia
-Disruption of sleep/wake cycle usually consisting of increased
energy
late in the evening and lowest energy level in the morning
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
sounds.
-Sensitivity to odors, even pleasant smelling chemicals such as
perfume.
Odors such as cleaning products, gasoline, strong foods,
etc. may cause extreme nausea, retching, vomiting, dizziness
and
headache.
Decrease production of saliva or excessive production of saliva.
-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.
-Comprehension difficulties. Inability to follow a conversation. May
hear
words but is unable to understand their context in the sentence.
Cannot focus on more than one activity at a time. May
not realize
they are being addressed. Losses conversation focus when topic is
changed. Is easily distracted from the
conversation focus by any
environmental stimuli.
-Memory recall deficits in long and short term memory. Improves with
lying
down and resting.
-Abdominal migraines. Severe stomach pain triggered by large meal or
by
sitting or standing too long. Usually resolves if patient lies
quietly.
-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.
-Tend to have mild symptoms of Ehlers-Danlos, but do not necessarily
test
positive for the disease. This includes hypermobile joints,
double joints, and soft, velvet-like skin that has little
or no
texture.
-Often has another auto-immune disorder.
-Family History of auto-immune disorder or symptoms that resemble
autonomic
dysfunction.
-Appears to have more viral illnesses than general population. Often
diagnosed
with Chronic Fatigue Immune Dysfunction Syndrome.
