Has anyone experienced brain fog that they feel is due to MG?

A MGteam Member asked a question 💭
Lufkin, TX

Although I just went through my first crisis in may and was just diagnosed in June. I have been experiencing symptoms gradually over the last 6 years. One of those was a kinda slight brain fog. Since I have been taking the meds for MG I’ve noticed it’s gone suddenly I remember where I put my keys , wallet and where I set that wrench down. My thoughts are crisper and my decision making has improved. I just figured it came with age. Just wondering anyone else dealing with this.

What a great silver lining to share — and yes, many MGteam members have experienced exactly this! Brain fog is more common with MG than most people realize, and it's often mistaken for just "getting older."

What a great silver lining to share — and yes, many MGteam members have experienced exactly this! Brain fog is more common with MG than most people realize, and it's often mistaken for just "getting older."

Here's what others have shared:

- "I have short-term memory lags."
- "My concentration and memory get better then worse, just like all my other symptoms."
- "I find that mental or cognitive activity can be just as draining as physical activity."

One MGteam member found a practical workaround, writing everything on a large block calendar to track daily tasks — and said it really helped! Research backs this up. Around 60% of people with MG report memory difficulties. The leading theory is that the same antibodies disrupting nerve-muscle communication may also reduce acetylcholine activity in the brain — affecting memory, learning, and thinking.

The fact that treatment improved the brain fog makes a lot of sense given how MG works at a neurological level. It's a really encouraging sign that the treatment is working well for you!
