OCD

Obsessive Compulsive Disorder is characterised by long term intrusive thoughts and fears that cause extreme anxiety, leading to the sufferer feeling they need to perform certain behaviours or rituals to alleviate their anxiety. This may give temporary relief but the thoughts always return, leading to repetition of the behaviour. Common themes are of security (excessively checking doors are locked etc) and hygeine or contamination.
We discussed OCD and its representation in the indie game Neverending Nightmares, with creator Matt Gilgenbach as part of The CheckPoint Series.
