My niece is in her early 20's. She's always been quite shy and lacking confidence. However, her condition has worsened in certain regards and my brother has told me it's been diagnosed as severe OCD. I'm not convinced and I'm concerned they are not getting a good diagnosis. I haven't seen my niece first-hand, so I'm just going on my brother's description of her behaviour. For several months now, she is awake every night until 5am. She is chanting number sequences. She cannot (for example) eat a plate of chips because she doesn't know in which order to eat them. She will call down from the top of the stairs and say she's stuck and doesn't know whether to move forward or back. She has even said "I can't open my mouth" through closed lips, when there is nothing physically wrong with her mouth. Can this really be simply OCD or should my brother seek a second opinion?
