The Roads Are Still There

On long-term chemo brain and what survivorship quietly changes

I finished chemotherapy in February of 2020. It is now February of 2026.

I am better. I am not the same.

During treatment, I functioned well. I worked. I followed the schedule. I managed side effects as they arose. There were steps, and I took them. When chemotherapy ended, everyone — including me — assumed normal would return.

It didn’t.

What followed is often called chemo brain, or, more formally, cancer-related cognitive changes.

At first, the changes were easy to dismiss. I had to stop and think through how my own daughter’s middle name was spelled — something I had once known without effort. I began forgetting birthdays. Not occasionally. Consistently.

Then words started disappearing mid-sentence. I would be speaking, fully aware of what I intended to say, when the word I had been holding in mind seconds earlier simply vanished. Conversations slowed. I learned to describe around missing language. Talking became a form of low-level problem-solving.

Even simple mental math slipped away. Not complex calculations — basic ones. The kind you usually do without noticing. I would know that we needed to pick up something at the grocery store, but not be able to hold the quantity in mind long enough to write it down. Then I would forget the name of the place where you write such things so you remember them later.

I am aware of how this sounds. It sounds implausible.

It isn’t.

What surprised me most was not the forgetting itself, but the effort required to think. Cognitive work began to feel costly. Tasks that once ran automatically now demanded preparation and recovery. Mental stamina became finite in a way it had never been before.

The most accurate image I have for this is infrastructural.

My brain once had roads to information. Some were wide, fast, efficient. I could move easily from one place to another. I could retrieve obscure facts without effort. Connections were quick and dependable.

Chemotherapy was not an eraser. It was a geological event.

The information was not destroyed. The roads were buried.

Since then, I have been rebuilding. Slowly. Deliberately. The routes I use every day — the skills and knowledge I rely on — I have excavated new access to those. The roads function, but they are narrower. Less forgiving. Learning something new now requires heavy equipment. Repetition. Alternate approaches. Time.

The things I don’t use regularly, I did not rebuild. Those routes remain inaccessible. If I ever needed them again, I believe they could be reconstructed — but it would be construction, not recall.

This is where misunderstanding often enters.

Many people do recover fully. Most patients experience significant cognitive improvement within the first year after treatment. But a meaningful minority do not. Roughly a quarter — sometimes more — continue to experience long-term cognitive changes years later. Those are the people whose roads never quite repave themselves.

From the outside, we look unchanged. From the inside, we navigate detours.

I now require different teaching methods. What once stuck immediately must be approached from multiple angles. Context matters more. Fatigue arrives sooner. Noise is harder to filter. Efficiency is no longer guaranteed.

This is survivorship’s quieter companion — the part that remains after treatment ends, after congratulations are offered, after life is expected to resume its former shape.

I survived cancer. That fact is simple.

What is less simple is surviving with a mind that works differently than it once did — not worse, exactly, but altered. More selective. Less tolerant of waste. More protective of its energy.

The roads are still there.

But the map has changed.
