Yes, I agree on that one. Generally cognitive impairment is not shared; mostly because even if a detailed description of what that may mean were included, people still tend to jump to their own conclusions and/or create their own story-line. It is not commonly known that for the most part, intelligence remains pretty much intact; even though the expression of it may be slower or impaired.

When the brain goofs, I find that brushing it off as a symptom of 'mental-pause' (my gender and age fit), satisfies most people and is an easy, light hearted way to move past the incident.

When cognition is really bad, I keep conversations to a minimum and carefully proof read all emails and correspondence. It is also less stressful to stay away from friends and family as well as the public; and thus I don't go to work at times like that.
In short, the more severe it is, the more I hide it as much as possible.
