Too Many Tabs

Cognitive fatigue does not look like anything. That is exactly the problem, for the survivor and for everyone else in the room.

Hi, I’m Michael, and I’m a stroke survivor.

I went into the meeting feeling good. Rested, prepared, on top of it. For the first half hour I was myself again: following the thread, seeing three moves ahead, ready to speak. If you had looked at me, you would have seen a man perfectly capable of running the room.

Then the tabs opened.

That is the only way I know how to describe it. My brain became a browser with too many tabs open, and I was flicking through them so fast that not one of them would load. The argument I had been tracking a moment earlier simply dissolved. Someone asked me a direct question and I could see the answer sitting there, just out of reach, behind a page that would not finish loading. I opened my mouth and what came out was either nothing or nonsense.

Here is the cruel part. I still looked completely fine. Same suit, same posture, still nodding along. Nobody in that room could see that the machine had quietly run out of fuel. My disability, invisible all morning, was now on full display, and I was the only one who knew it.

What it actually is

The doctors call it cognitive fatigue, and it is the symptom I find hardest to explain to people who have never had a brain injury. It is not being sleepy. A good night’s sleep does not touch it. It is not a lack of effort, and you cannot push through it with willpower, which is a bitter thing to learn when pushing through was the whole basis of your career.

It is your thinking apparatus reaching the end of its charge. Sometimes it warns you. Often it does not. It can arrive after an hour of looking flawless, and when it comes, the first thing to go is the very thing you were valued for: your judgement, your grip on the detail, your ability to hold the whole picture at once.

For someone whose identity was built on being the sharpest person at the table, that is not just inconvenient. It is frightening.

The reflex that betrays you

Every instinct I had built over thirty years told me to power through. Tired? Work harder. Struggling? Do not let them see it. That reflex got me everywhere I ever wanted to go.

After a stroke, that same reflex is the thing most likely to set you back. Pushing through cognitive fatigue does not build tolerance the way training a muscle does. It just empties the tank further and steals days from your recovery. The discipline I used to spend on working longer, I now have to spend on stopping sooner. It is the same discipline. I have just had to point it in the opposite direction.

That is not weakness. It took me a long time to believe that sentence, so let me say it again for anyone who needs it as much as I did. Managing your fatigue is not weakness. It is the new shape of the strength you already have.

For the person watching

If you manage someone who has come back from a stroke, this is the part I most need you to hear.

Looking fine is not the same as being fine. The colleague nodding along in your meeting may be flicking through those frozen tabs while you speak. They will almost certainly not tell you, because the kind of person who reaches a senior role is the last kind of person to raise their hand and say they are struggling.

So do not wait for them to. Do not read a blank moment as them being unprepared, or disengaged, or past it. Build the breaks in before they are needed. Put the check-in in the diary yourself. Ask what helps, in private, and then believe the answer. The most capable person you know can be quietly drowning while looking, to you, entirely calm.

The close

I have learned to feel the tabs beginning to open now, most of the time, and to step out of the room before they freeze. It is not a cure. It is a truce.

I am not less committed than I was. I am not less able. I am running the same drive I always did, on a battery that warns me less than it used to. Understand that, whether you are living it or leading someone who is, and you understand almost everything about coming back to real work after a stroke.

I look fine. Now you know what that can cost.
