How IV Infusion Therapy Helps Brain Fog
“Brain fog” is a vague term that refers to feeling, well, vague. When you have brain fog, you’re sluggish and unfocused, and everyday tasks can seem impossible. You have trouble remembering and concentrating, too. Infusion therapy can help.

Just as driving through a fog slows you down because you can’t see clearly, a foggy brain makes it more difficult to get through your day with ease. Your brain takes longer than usual to accomplish its basic tasks, including:

  • Paying attention
  • Remembering
  • Making decisions
  • Finding the right words
  • Reading with retention
  • Having a conversation

You may find it difficult to follow the storyline of a TV show or movie. Or you could just be overcome by a general sense of fatigue. You can’t figure out how to fire yourself up, and when you try, your brain isn’t up to it.

Brain fog is a type of cognitive impairment that could have many causes at its root, including a condition such as Alzheimer’s disease or another form of dementia. It could also be related to an underlying illness, hormonal imbalance, or even dehydration.

Our experienced and caring neurologists at Advanced Medical Care in Queens and Brooklyn, New York, first conduct a thorough examination to ensure you don’t have a disease that needs treatment. Whatever the cause of your brain fog, IV infusion therapy may help you feel better and restore your brain’s efficiency and speed.

Here’s how IV therapy helps brain fog.

Your brain is mostly water

Water accounts for about 75% of your brain’s mass. In order for your brain to function optimally, you must stay hydrated. In fact, dehydration is a common cause of brain fog. Restricting your water intake for 16 hours can cause your brain to shrink by 0.55%. 

Even a loss of 2% of your body’s hydration can slow down brain function. Conversely, restoring hydration can help clear brain fog. To have a healthy brain, you need to drink plenty of fresh water and eat water-rich fruits and vegetables. When you need a boost, you can turn to IV therapy.

One of the benefits of IV therapy is that it hydrates all of your cells — including your brain cells. While you relax and receive your IV drip, you may even feel a surge of energy as your brain finally gets the hydration it needs to clear toxins and function efficiently.

Your brain needs to detox

Your brain needs water to detoxify and remove heavy metals and environmental poisons through the glymphatic system. When toxins build up in your brain, either due to dehydration or heavy-metal exposure, your brain function slows down.

In addition to supplying your brain with the hydration it needs to detox and pick up speed, an IV glutathione infusion resupplies your brain with this important tripeptide. Glutathione aids in the detoxification process and blocks your brain cells from oxidative stress and other damaging influences. Glutathione helps repair cellular damage and build new tissues.

Although the liver produces glutathione, diseases, aging, and stress interfere with that healthy production. An IV infusion gives your body and brain the glutathione it needs to keep cells healthy and robust so your neurons fire signals quickly and efficiently.

You need to relax

Another benefit of IV infusion therapy is that it’s completely untaxing and relaxing. You don’t have to do anything. There’s no pain or discomfort. You simply relax in a comfortable treatment chair as the IV fluid drips into your body over the next 30-60 minutes.

You also need to sleep well. If you’re not getting sufficient or high-quality sleep, your brain can’t function at its best. That drowsiness you may feel on waking up persists throughout the day.

An IV infusion lets you take a relaxing break while your brain and body are suffused with hydration, antioxidants, vitamins, and minerals. You may even fall asleep in the chair. You may also find that you have the best sleep in recent memory after your treatment, thanks to the extra support for your brain.

An IV infusion gives your brain what it needs

Brain fog can have many causes, including nutritional deficiencies. When we do a workup to determine the cause of your brain fog, we look at your nutritional status, too. If we find that you lack key nutrients, we may add them to your IV “cocktail.”

Once your brain fog clears, you should also adopt lifestyle adjustments that help your brain work the way it should. This may include:

  • Eliminating ultraprocessed foods
  • Eating more fresh vegetables
  • Getting enough high-quality protein
  • Drinking sufficient water and healthy liquids
  • Exercising and moving more
  • Getting enough high-quality sleep

You may also benefit from regular IV infusions to be sure your brain gets the glutathione and hydration it needs to keep you mentally sharp, alert, and energized.
