Cognitive dysfunction from allergies: Not Just Snot

When most people think of allergy symptoms, the typical sneezing, runny nose and itchy eyes come to mind. However, allergy sufferers are also subject to cognitive dysfunction. Cognitive dysfunction is the symptom complex which interferes with concentration and the ability to complete routine tasks.

Swelling of the nasal passages due to allergies leads to congestion, headaches, and disruption in breathing. As a result insomnia, sleeplessness, fatigue and irritability can occur. Although these symptoms are not life-threatening, they can contribute to poor test performance, school absence, and reduced work productivity.

In addition to the symptoms triggered by allergies, sufferers may try to treat their symptoms with various over the counter products. Most antihistamines cross the blood-brain barrier and induce drowsiness. In most states, allergy sufferers who take antihistamines and drive may be subject to a DUI (Driving Under Influence) arrest. Decongestants, another over the counter remedy, can exacerbate hypertension, provoke irritability and induce jitteriness.

Allergies can be serious medical problems. The diagnosis and management should be done by a qualified specialist such as an internist or pediatrician certified by the American Board of Allergy and Immunology.
