How it may present

- Progressive memory changes
- Difficulty planning or problem-solving
- Gradual decline in other forms of thinking
Why it matters
FAD does not just affect individuals, it affects whole families, often across generations. Questions about genetics, future risk, and planning can be deeply challenging.
