Fabry Disease

The Brain & Nerves

GL-3 build-up in the blood vessels associated with the brain and nerves may cause several different types of symptoms.

Fabry crises
Fabry crises (episodic paresthesia) are episodes of severe, burning pain that starts in the hands and feet and spreads to other parts of the body. Pain crises are often one of the first signs of Fabry disease and may be the most disabling aspect of the disease. The painful episodes may last from minutes to weeks, and are often brought on by stress, illness, temperature change, or fatigue. Fabry crises may be accompanied by a fever. In some people, the pain can be eased with prescription drugs, such as carbamazepine (Tegretol), diphenylhydantoin (Dilantin), or gabapentin (Neurontin).

Other pain
Some people may have a chronic burning, tingling pain (acroparesthesia) in the hands and feet that is not a true Fabry crisis. This pain may also be brought on by stress, illness, temperature change, or fatigue. The above medications may also be prescribed for people with this type of pain.

Blood clots and stroke
People with Fabry disease have a higher risk of blood clots (thromboses), which can cause stroke. The risk of stroke is even higher in people with Fabry disease who have kidney problems, since they are likely to have high blood pressure. The risk of blood clots can be lowered with the use of prescription drugs called anticoagulants (blood thinners). A daily dose of baby aspirin may also be recommended to reduce the risk of clotting.

Hearing loss
Some people with Fabry disease also have hearing loss and ringing in the ears (tinnitus).

Other effects
Other symptoms that can occur due to GL-3 build-up around the brain and/or nerves include: dizziness, double vision (diplopia), difficulty with speaking (dysarthria), head pain, unsteadiness while walking (gait ataxia), and weakness of one arm or leg (hemiparesis).
