Have you read the article?

Under Dutch law, to be eligible for an assisted death, a person must be experiencing “unbearable suffering with no prospect of improvement”. They must be fully informed and competent to take such a decision.

After 10 years, there was “nothing left” in terms of treatment. “I knew I couldn’t cope with the way I live now.”

In the three and a half years this has taken, I’ve never hesitated about my decision.

How is this a temporary and overcomable problem? It seems clear that it is not temporary and no kind of treatment worked for her. As per the law, there must be unbearable suffering without prospect of improvement, and during the multiple stages of this process, apparently no one came to the conclusion that that wasn't the case for her. So how can you make that assessment?
