Most approaches to treating depression are based on the assumption that the illness is caused by psychological, biochemical, genetic and environmental factors. However, allergies may also be the culprit in some individuals and depression caused by allergies may be more easily addressed than other causes.
How Allergies Affect the Brain and Nervous System
Signs and symptoms of depression include anxiety, sadness, irritability, hopelessness, despair, erratic thoughts and loss of concentration and motivation. More physical symptoms such as chronic headaches and stomachaches can also occur. Some allergies may not necessarily affect the skin, respiratory system and digestive system but may cause depression-related symptoms such as anxiety, panic attacks, irritation, compulsive-obsessive behavior and psychotic episodes.
Increasing research indicates a relationship between allergies and depression. A study published in the American Academy of Environmental Medicine shows that allergic reactions do affect the nervous systems, causing depression in some people. Approximately 70 percent of individuals with depression also have a history of allergies.
Allergies can affect any organ and system in the body and allergies that affect cerebral structures in the brain may be one possibility of why depression can result. The limbic system is the region of the brain that is regulates the sex drive, emotions and stress reaction. Allergies occur due to hypersensitivity reactions in the immune system and can also cause disturbances in this region of the brain, affecting mood and behavior. Some food allergies can also cause a deficiency in vitamins and other nutrients that affect emotions, causing or worsening depression.
The Role of Genetically Modified Foods and Cytokines
According to the American Academy of Environmental Medicine, genetically modified foods may cause significant immune disturbances by increasing cytokine levels in the body. This chemical is associated with allergies, asthma and the inflammatory response. Cytokine levels also influence the release of a chemical in the brain that plays a role in feeling of anxiety, depression, lethargy and a loss of concentration.
The best way to eliminate depression symptoms that are related to allergies is by decreasing the allergens that are causing the illness. This includes allergens such as pollen, dust, mildew, mold, household chemicals, animal fur and dander and food allergens.
Eliminating GM modified foods and food additives such as MSG, dyes and artificial flavors may also help. Keeping a food diary that lists foods eaten and symptoms experiences on a daily basis, can help to pinpoint whether a certain food or chemical is responsible.
