Q

mental illness

A

The American Psychiatric Association defines mental disorder as a clinically significant disturbance in an individual’s cognition, emotion regulation, or behaviour. It is sometimes difficult to apply that definition, because of disagreements over what constitutes a significant disturbance.

Q

What is the categorical approach?

A

The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) lists possible diagnoses and the criteria for identifying each of them.

However, most troubled people partly fit two or more diagnoses. Also, the genetic and environmental causes of various disorders overlap, and the treatment designed for one disorder may help with another. An alternative is to rate each person along several dimensions of distress.

Q

What happens with the persistence of avoidance behaviours?

A

A learned shock-avoidance response can persist long after the possibility of shock has been removed. As with shock-avoidance responses, phobias persist because people do not discover that their avoidance behaviours are unnecessary.

Q

common phobias

A

People are more likely to develop phobias of certain objects (e.g., snakes) than of others (e.g., cars). The most common objects of phobias have menaced humans throughout evolutionary history. They pose dangers that are difficult to predict or control, and we generally have few safe experiences with them.

Q

What are treatments for OCD?

A

The most effective treatment is exposure to the source of distress while preventing the ritualised response. However, this treatment is often ineffective, partly because many patients refuse or quit the treatment. A valuable supplement is a cognitive intervention to help people reinterpret their thoughts and images.

Q

What are motivations behind addiction?

A

People with an addiction continue a habit even though they recognize that it does them more harm than good. Reasons for continued use include avoiding withdrawal symptoms and coping with distress. Also, addictive substances alter the brain’s synapses to increase response to substance-related experiences and decrease response to other activities. In spite of all this, some people do manage to quit.
