A unique element of financial planning is that client relationships can last for a very long time, with many advisors assisting clients over the course of decades as their financial planning needs evolve in step with their personal lives. Due to this aspect of the planning relationship, it is almost inevitable that an advisor will encounter a time when a client is diagnosed with a terminal illness. And while it is important for the advisor to review technical areas of the financial plan (from cash flow to estate planning) with these clients, an even more critical consideration is how to best communicate and interact with a client whose thoughts are consumed by their illness. If the advisor isn’t aware of the strategies for working with a client with a “sick brain”, all the best financial plans will be useless.
