Brain fog is not a medical diagnosis. It’s a general term used to describe the feeling of being mentally slow or spaced out. It’s normal to get brain fog occasionally. When you’re under stress, you could feel fuzzy or sluggish. A night of poor sleep could also give you brain fog the next day. Your brain isn’t alert enough, leaving you to feel slow. But if you get brain fog often, it’s a sign of concern. You should get a checkup done.

Symptoms of brain fog include having problems with remembering and recalling things, lack of mental clarity, and feeling “out of it”. Lack of concentration, poor cognitive skills, headaches, and confusion are some other signs and symptoms of brain fog. Have you ever gotten brain fog? Did you ever get to the bottom of why?

Multiple sclerosis

If you have MS, your central nervous system, consisting of the brain, spinal cord and optic nerves, gets affected. The nerves connecting the brain to the body get damaged, which means communications are disrupted. People with MS tend to have trouble making decisions.

You would also see some changes in your ability to process information and retain it. The changes you experience are more or less moderate, and do not necessarily affect your day-to-day life. But you will tend to feel frustrated over your inability to complete tasks as simple as finding your keys or shopping.

Fibromyalgia and chronic fatigue syndrome

Fibromyalgia is where you feel muscle pains, as well as tenderness throughout your body. If you suffer from this, you’ll find that your concentration is affected. You will also have memory lapses.

Depression and stress

If you’re suffering from depression, not only will it affect how you feel, but also how you think. It can cause problems related to memory and focus. Together, they combine to increase brain fog. Depression can also impact your reaction time. If you’re completing tasks a lot slower than you used to, or you feel that your brain is blocked while doing those tasks, it could be because of brain fog.

Another casualty of this condition is your inability to make decisions. You also tend to worry a lot about all the likely outcomes of making a decision, which can impair your ability to make a choice. You may also not be able to multitask. Stress and anxiety have the same effect.

Iron deficiency anemia

This is the most common type of anemia. You have anemia when there aren’t enough red blood cells in your body. This causes tiredness, as the red blood cells carry oxygen to all your body’s tissues. Iron deficiency anemia is caused when there’s very little iron in your body. You will feel both mentally and physically tired due to this condition. As a result, you tend to feel shortness of breath and experience brain fog as well.

Hormonal changes

If there are changes in your hormonal levels, it can affect how your brain functions. This is especially true for women during pregnancy or menopause.

The results also showed they had problems focusing their attention on challenging tasks. Conditions such as hypothyroidism can cause an imbalance in your hormones.

Postural tachycardia (tacky-cardia) syndrome

You’ve probably never heard of this, but it needs to be mentioned nonetheless. When you stand up after lying down, you may feel an unusual change in your heart rate. This comes with a change in your blood pressure as well. Such a condition is called postural tachycardia syndrome (POTS). A study among adolescents showed those with POTS had symptoms similar to brain fog. The participants tended to suffer from confusion and were forgetful. They also had cloudy thinking, and even problems focusing and communicating.

Alzheimer’s disease

If you have Alzheimer’s disease, you will have symptoms similar to that of brain fog. This is also the case in many other forms of dementia. You get Alzheimer’s disease when there’s a lot of protein buildup in your brain. While protein is normally good for your body, this build up actually affects your brain’s functioning.

  How to prevent blood clots

You also lose connections between the neurons in the brain. This disease completely destroys your memory and other mental functions. Although the condition mainly affects people over the age of 65, about 10% of patients are younger than that. There are about 5 million Americans with Alzheimer’s disease. This number is expected to triple by 2060.

Sleep apnea

When you go to sleep, the muscles in the back of your throat relax. This can sometimes cause you to have trouble breathing while asleep. This is where sleep apnea occurs. For people with this condition, quality of sleep declines rapidly. You tend not to get enough rest, and you’re cranky throughout the day. This is where brain fog comes in. Of course, there is treatment for this.


Sometimes, the meds you take for other conditions are the reason you’re having symptoms related to brain fog. While medication is necessary for whatever condition you’re being treated for, you should talk to your doctor about the side effects. Chemotherapy drugs certainly have a reputation for making a person weak. It causes brain fog as well, with cancer survivors referring to it as chemo brain. Sleeping pills also have the same effect.

While they give you a restful sleep, you end up groggy and have brain fog. Other pain relief medications seem to cause similar symptoms. If you’re taking drugs for anxiety, one of the side effects is brain fog. There may be alternative meds that don’t make you feel like this. But you’ll need to speak to a doctor before you take them.
