This is one of the better (if not long winded although there is an even longer version!) definition of addiction –
“Addiction is a primary, chronic disease of brain reward, motivation, memory and related circuitry. Dysfunction in these circuits leads to characteristic biological, psychological, social and spiritual manifestations. This is reflected in an individual pathologically pursuing reward and/or relief by substance use and other behaviors.
Addiction is characterized by inability to consistently abstain, impairment in behavioral control, craving, diminished recognition of significant problems with one’s behaviors and interpersonal relationships, and a dysfunctional emotional response. Like other chronic diseases, addiction often involves cycles of relapse and remission. Without treatment or engagement in recovery activities, addiction is progressive and can result in disability or premature death.”
Latest Definition of Addiction by the American Society of Addiction Medicine (ASAM)
Another definition on the NIDA website is “Addiction is defined as a chronic, relapsing brain disease that is characterized by compulsive drug seeking and use, despite harmful consequences. It is considered a brain disease because drugs change the brain; they change its structure and how it works. These brain changes can be long lasting and can lead to many harmful, often self-destructive, behaviors.”
We will address and hope to add to these definitions in this blogsite!”
In this video from SciShow, Hank describes how our brains respond biochemically to various addictive substances and behaviors and where those responses have come from, evolutionary speaking.
