Brain fog can be a debilitating side effect of treatments for various illnesses. It can cause problems with focus, memory, and decision-making.
If you are experiencing brain fog during your treatments, don’t worry—you are not alone.
This guide will provide information on treatments that cause brain fog and steps you can take to help manage the symptoms more effectively.
Let’s get started.
What is brain fog, exactly?
Brain fog is a condition that can cause problems with thinking, remembering things, making decisions, and focusing on tasks.
There are several causes of brain fog, including treatments for various illnesses, such as cancer, Lyme disease, and multiple sclerosis.
The reason why some treatments cause brain fog is not known. However, it is observed to be related to the body’s inflammatory response to treatments.
Symptoms of Brain Fog
The symptoms of brain fog can vary from person to person. However, common symptoms include:
- problems with focus and concentration
- difficulty remembering things
- difficulty making decisions
- struggles with thinking clearly
- struggles with thought organization
If you are experiencing any of these symptoms, you may be suffering from brain fog.
Common Treatments that Cause Brain Fog
Some of the most common treatments that have been observed to be causing brain fog include:
Chemotherapy is a treatment for cancer that uses drugs to kill cancer cells. Unfortunately, chemotherapy can also damage healthy cells, including the brain cells that are responsible for learning, focus, and memory.
Some studies show that the majority of cancer patients experience brain fog during chemotherapy treatments.
Hormone therapy is a treatment that uses hormones, commonly estrogen and progesterone, to treat various conditions, such as menopause and cancer. This type of therapy can cause brain fog by affecting the levels of neurotransmitters in the brain.
A study of women undergoing hormone therapy found that those who experienced the most significant changes in hormone levels were more likely to experience short-term cognitive impairment during the treatment.
Immunotherapy is a treatment that uses substances to stimulate the immune response to fight against diseases, such as cancer. This type of therapy can cause brain fog by affecting the levels of inflammation in the brain.
A study of cancer patients found that those who underwent immunotherapy treatments were more likely to experience brain fog and other types of cognitive impairment during and after therapy, although the effect is not long-term.
Radiation therapy, also called radiotherapy, is a treatment that uses high doses of radiation to shrink tumors and kill cancer cells. Unfortunately, radiation therapy can also damage healthy brain cells, which can lead to brain fog.
A study of cancer patients found that those who underwent radiation therapy treatments were more likely to experience problems in their brain function during treatment.
Surgery is a treatment that involves the removal of diseased tissue. It can cause brain fog by affecting the levels of hormones and inflammation in the brain, which also depends on the amount of anesthesia used.
A study of patients who underwent surgery found that those who experienced the most significant changes in hormone levels and inflammation were more likely to suffer from brain fog.
Lyme Disease Treatments
Lyme disease is a bacterial infection that is transmitted by ticks. It can cause a wide range of symptoms, including brain fog.
The standard treatment for Lyme disease is a course of antibiotics. Unfortunately, as studies show, antibiotics can also kill the healthy gut bacteria that are essential for cognitive function.
Multiple Sclerosis Treatments
Multiple sclerosis is a chronic autoimmune disease that affects the nervous system. The most common treatments for multiple sclerosis are immunosuppressants, which can cause brain fog in some patients.
A study of brain fog in multiple sclerosis patients found that treatments that suppressed the immune system were more likely to cause brain fog than treatments that did not.
Some of the most common medications that have been linked to brain fog include:
Antianxiety drugs, such as benzodiazepines, are a type of medication that is used to treat anxiety disorders. Unfortunately, they can also cause brain fog by affecting the levels of chemicals in the brain.
A study of people with anxiety disorders found that those who took antianxiety drugs were more likely to experience brain fog.
Antidepressant drugs, such as selective serotonin reuptake inhibitors (SSRIs), are a type of medication that is used to treat depression. Unfortunately, they can also cause brain fog by affecting the neurotransmitters in your brain.
A study of people with depression and obsessive-compulsive disorders (OCD) found that those who took antidepressant drugs were more likely to experience brain fog.
Antiseizure drugs, such as carbamazepine and valproate, are a type of medication that is used to treat epilepsy. Unfortunately, they can also cause brain fog by affecting the levels of chemicals in the brain.
In a recent study of persons with epilepsy found that people who took antiseizure medications were more prone to experience cognitive fog.
Hypertension drugs, such as beta-blockers, are a type of medication that is used to treat high blood pressure. Unfortunately, they can also impact the amounts of chemicals in the brain, often resulting in brain fog.
According to research on elderly people with hypertension, those who took antihypertensive medicines were more likely to suffer from brain fog during the treatment.
Sleeping aids, such as Ambien and Lunesta, are a type of medication that is used to treat insomnia. Unfortunately, they can also cause brain fog by affecting the levels of chemicals in the brain.
A study from Harvard Medical School found that those who took sleeping pills were more likely to experience brain fog.
Antihistamines, such as diphenhydramine and cetirizine, are a type of medication that is used to treat allergies. They can also cause drowsiness, blurred vision, and headache as side effects which often lead to brain fog.
According to research on people who suffer from allergies, those who use antihistamines are more prone to experience cognitive fog.
Narcotic painkillers, such as oxycodone and morphine, are a type of medication that is used to treat pain. Unfortunately, they can also cause brain fog by affecting the levels of chemicals in the brain.
A study on people with chronic pain found that those who took narcotic painkillers were more likely to experience brain fog.
