A very interesting and clear animation: 'Are All Mental Illnesses Related?'.
"David Kessler, the former Commissioner of the Food and Drug Administration, argues that all mental health issues, including addiction, depression, and overeating, can be explained by “capture”—a process where focusing on selective stimuli results in adverse behaviors. In opposition to current research, Kessler argues against the notion of chemical imbalances and offers capture as a common mechanism which accounts for all forms of mental illness."
