The comprehensive effects of a cognitive disability are not observable until people stop talking. Within ACL 3 Low, denial is no longer possible because these people cannot say much. Above ACL 3 High, the whole world has been denying the comprehensive effects for centuries. As you provide educational information, you can expect the phrase "to shoot the messenger" to acquire personal meaning. The reality is grim. Period.
Some people will reject the idea of a lifelong cognitive disability and any subsequent change in their lifestyle; education has no effect on their rejection. They are prime targets for charlatans with false promises that cost money.
Some people will accept a temporary cognitive disability and expect a return to normal; education has little effect on their belief systems. Belief systems include religions and faith in psychotherapy and case management. Experience in living with a long-term cognitive disability is not as effective in changing belief systems as one might assume. They are prime targets for false promises made by transitional and wellness programs.
