What does the book title "A Mind Unraveled" mean? Hello, I'm currently reading the memoir “A Mind Unraveled” whose author has epilepsy. I'm not sure what the meaning of "unravel" is here. I wonder whether the title means his mind was somehow falling apart during those years or more like, he wanna reveal his thoughts and clarify this disease to the public. Or could it be both and depends actually on the content of the book? Thank you :)

In what kind of situation do people use "descendant"? Hello, I'd like to ask when the word "descendant" is usually used. For example, I wanna express "the old man is abused by his son". Can I use "descendant" to refer to his son? Does a sentence like "he suffers maltreatment from his descendant" sound natural? or it is a word that should rather be used to refer to the generation after several generations or maybe hundreds of years? thank you so much :)
