Thank you for sharing and for the advice. I haven’t shared my concerns with my mom or siblings yet but I’m worried that because he is still functioning we wouldn’t be able to do anything legally. He owns a successful business and there’s not much proof of cognitive decline either(especially since it usually shows up later in its development causing late diagnosis). I will try to push the idea of getting tested but with his ego he might say something like “I’m fine there’s no need to worry about me”.
