How MS Affects the Brain
When you’ve got multiple sclerosis, losing your keys or forgetting a name can be scary. You wonder whether the illness is clouding your thinking.
It’s true that over time, about half of people with MS can have some cognitive problems. That means poor focus, slowed thinking, or a fuzzy memory.
Often these problems are mild and don’t really interrupt your daily life. It’s pretty rare to have severe thinking problems. They affect about 5% to 10% of people with MS.
