No need to apologize — this is a great question, and you are absolutely not imagining things! There is a very real connection between mental effort and exhaustion in MG.

Research has found that cognitive (thinking and reasoning) activity can be just as draining as physical activity for people with MG. In fact, one MGteam member put it perfectly: "I find that mental or cognitive activity can be just as draining as physical activity." Here's why this happens. MG involves autoantibodies that block acetylcholine receptors. Acetylcholine isn't just active in your muscles — it also plays a key role in brain functions like:

- Memory
- Learning
- Thinking and planning

When those receptors are disrupted, it can reduce acetylcholine activity in the brain, making mental tasks genuinely exhausting — not just a feeling. Studies have also shown that certain areas of the brain can be structurally affected in people with MG, which links directly to lower scores on memory and learning tests.

So that "cliff of exhaustion" you're describing after serious mental effort? Completely valid, and well-documented. Wile E. Coyote would understand — gravity doesn't care whether you ran off the cliff or just thought really hard about it. 😄

It's worth discussing with your doctor, as they can help identify strategies to manage cognitive fatigue alongside your other MG symptoms.
