• out of context
• exaggerated or excessive

• may interfere w/ normal functions

Question 10

Etiology of compulsive disorders

Answer 10

multifactorial causes. Probably involves NT changes. Can have ACQUIRED causes (ie. conflict, frustration, stress, inappropriate environments, physical lesions, etc.) or GENETIC causes (some genetic strains are predisposed to develop compulsive disorder)

oriental cat breeds are predisposed to which compulsive behaviors?

Answer 20

Question 21

when diagnosing compulsive disorder (CD), you should rule out:

Answer 21

Question 22

6 classifications of compulsive disorder. How are they classified?

Answer 22

• LIGVAH
  1. Locomotion
  2. Ingestive
  3. Grooming
  4. Vocalization
  5. Aggression
  6. Hallucinatory

Question 23

Examples of locomotion CD

Answer 23

circling, tail chasing, pacing, digging, freezing, shadow chasing

Question 24

examples of grooming CD

Answer 24

chewing/licking self, flank sucking, self-mutilation

Answer 30

Answer 31

the study of how different behaviors rely on different neural pathways. May explain differential responsiveness of various forms of OCD to different medications.

Answer 32

rule out medical problems, treat concurrent medical conditions

Question 33

what environmental modifications need to be made with CD?

Answer 33

- identify/remove cause of conflict - reduce env. stress - provide sufficient stimulation - provide consistent exercise schedule - provide predictable env.

Question 34

behavioral modifications for CD

- structured interactions - no punish. - avoid reinforcing undesirable behaviors - response substitution - distract and redirect* - DS/CC to stress-inducing scenarios
