7. Confusion or memory lapses
Forgetting recent conversations, having difficulty following simple instructions, or feeling mentally foggy for short periods may be early signs. This feeling is similar to “brain fog,” but it occurs more frequently than usual and may occur along with other symptoms listed here.
