Compulsive disorders Flashcards
What is a compulsive disorder?
- Involves abnormal, repetitive behavior resulting from anxiety or stress without an apparent inciting trigger and when other physical or behavioral causes have been ruled out
- Difficult to disrupt
- May be self-reinforcing and difficult to interrupt without physical intervention
- often disrupts daily functions due to the intensity and frequency
- The diagnosis for 2-5% of patients seen by veterinary behaviorists
- May actually be higher number as thought to be under-reported
- Owners often don’t seek help until symptoms are severe
What are the clinical characteristics of Compulsive disorders?
- Categories for dogs are very diverse range of behavior
- Locomotor
- Visual/hallucinatory
- Oral
- Self-directed
-
Breed predilections
- Flank-sucking Dobermans
- Altered function in the subcortical region of the brain
- Flank-sucking Dobermans
- Affects serotonergic and dopaminergic regions
- Affected dogs have lower serotonin-receptor binding
What are the Locomotor Compulsive Behaviors?
- Circling/spinning
- Tail chasing
- Pacing
What are the visual/hallucinatory compulsive Disorders?
- Light or shadow-chasing
- Fly snappers
What are the oral compulsive disorders?
- Pica
- Licking
What are the self-directed or self-injurious compulsive disorders?
- Flank sucking
- Hind checking
- Acral like dermatitis
What is the Pathophysiology of Compulsive Disorders?
- Likely multifactorial
- Learning
- can be part of the inciting cause and perpetuation of CD
- Owners may inadvertently reinforce
- Over time, the behavior becomes so engrained that it continues, even the inciting cause is no longer there
What are the history and clinical signs of compulsive disorders?
- Symptoms in dogs often start prior to a year of age
- Median <1 year for tail chasing and flank sucking
- Median >1 year for acral lick dermatitis
- Owners often don’t present dogs until they are older for treatment
- Concurrent behavioral issues often present in 75% of dogs with CD
- Separation anxiety
- Aggression
- Generalized anxiety
- Attention seeking disorders
How are compulsive disorders diagnosed?
- Diagnosis of exclusion
- PE and diagnostic testing may show abnormalities secondary to behaviors associated with chronic CD
-
A thorough history is needed
- Description/video of the behavior
- Initiating factors
- Situations where behavior will likely occur
- Owner response
- Attempted treatments and success
- Behavior history forms are useful
Are all repetitive behaviors compulsive?
- NO
- alternative causes must be ruled out
What is displacement behavior?
- Normal behavior displayed at inappropriate times, or out of context, in response to anxiety-provoking events
- EX: dog licking paw when alone
- Occurs during stressful situations
- Remains linked to the anxiety-provoking situation
- Can evolve into CD with repetition or additional stress
What are differential diagnosis for repetitive behavior?
- Displacement behavior
- Redirected behavior
- Vacuum activity
- Stereotypy
- Audience-responsive behavior
What is redirected behavior?
- Behavior incited by one target but directed at another
- EX:
- Pruritic dog that licks inside of an Elizabethan collar when it cannot lick itself
What is Vacuum activity?
- Behavior performed in absence of normal stimuli required for that behavior
- Ex:
- Border collie that runs laps when not exercised
What is stereotypy?
- Repetitive, unvarying behavior with no apparent goal or function displayed by captive animals lacking appropriate enrichment or outlets
- EX:
- Dog confined to a small kennel without toys or social contact that jumps on the door in an invariant pattern
What is Audience-responsive behavior?
- Operant-conditioned behavior performed to solicit interaction with humans and in the presence of a human and has past reinforcement
- Ex:
- Light-chasing dog that stops when owner leaves and has historically been offered a toy when it chased lights
What are the Key components of Management and Treatment of Compulsive Disorders?
- Client education
- Minimizing repetitive behavior
- Reinforcing alternative behaviors
- Alleviating patient stress
How does Client education affect Compulsive disorders?
- Punishment based training
- Can increase aggression
- Can increase likelihood o injury
- Can increase anxiety
- Exacerbate CD
- Educated owners are less likely to use punishment-based training when they are informed that CD is due to anxiety and NOT due to dominance behavior of lack of training
How does Minimizing Repetitive Behavior affect Compulsive Disorders?
- Treatment should focus on behavior prevention
- The more a dog performs the repetitive behavior, the more ingrained it becomes
- Pet owners should try to identify situations that invoke compulsive behavior and try to avoid them
- Owners need to prevent unintentional reinforcement
- Don’t provide or take away positive reinforcements while the repetitive behavior is occurring
How dos Reinforcing Alternative Behaviors affect Compulsive Disorders?
- Dogs should be taught an alterative behavior that can be cued or reinforced whenever repetitive behavior is likely to occur
- Dogs that pace
- try to get them to fetch
- Shadow Chasers
- reward for lying down with chin on the floor
- Pica behavior
- feed from puzzle toys
- Owners should use cue-response-reinforcement patterns
- Give a cue
- God needs to respond
- Give a treat/toy/praise if responds appropriately
- When undesirable behavior is demonstrated
- Attention should be withdrawn
- Dogs that pace
How does alleviating patient stress affect Compulsive Disorders?
- Pharmacological intervention to address anxiety
- Clomipramine
- Fluoxetine
- Higher doses of medications may be needed for CD
- Be careful of side effects
- There are no FDA approved medications for CD
- Owners should not be inconsistent with their interactions
- Can cause:
- Anxiety
- Frustration
- Confusion
- Predictable interactions help to mitigate stress
- Can cause:
What is Cue-response-reinforcement?
- Give a cue
- Dog needs to respond
- Give a treat/toy/praise if responds appropriately
What environmental modifications and physical restraint can be used for Compulsive Disorders?
- Opaque privacy film on reflective surfaces (light chasers)
- Walk on leash to eliminate (yard pacers)
- Barriers (baby gates, tethers, pens/crates) o prevent access to trigger environments and restrict movement
- minimize repetitive locomotor behavior
- Self-inflicted trauma
- E-collars
- Bandages
- Muzzles
What pharmacological interventions are used to address anxiety in CD?
- Use drugs that affect Serotonin levels
- Clomipramine
- Common drug choice for CD
- Tail chasing in terriers
- 1-2mg/kg PO BID
- Fuoxetine
- Effective as clomipramine for tail chasing
- More effective than placebo for acral lick dermatitis
- Owners more apt to report decrease in severity of CD but not in frequency or duration
- 1-2 mg/kg PO SID
Are there pharmaceutical treatments for CD?
- No FDA approved medications
- Get informed consent from client, especially if higher doses are used
- Side-effects: Bradycardia and arrhythmias
What is the Prognosis of CD?
- Guarded to Fair
- Owners need realistic goals and expectations
- Reduction of severity and duration is the goal
- Treatment is unlikely going to be able to be stopped
- Focus treatment on Quality of Life
- Distraction from repetitive behavior
- Limit self-trauma
- Enjoyable activities and interactions with owner
- Preemptive intervention has best chances for success
What additional steps need to be taken to manage CD?
-
Frequent communication with owner is necessary
- monitor patient’s response to treatment
- Make adjustments to therapy, if needed
- Communicate to owners that stressful situations may exacerbate or trigger a relapse of CD
- Compulsive behaviors can be managed and quality of life can be improved for all
What causes Feline CD?
- Physical and environmental stressors have be implicated
What triggers wool-sucking?
- Stressful events
- being left alone for extended durations
- Early weaning (<7 weeks of age)
- Increase that risk for wool-sucking and overgrooming
- Has not been associated with n increased risk for pica
- Medical issues
- cardiovascular disease, neoplasia, allergies
What breed predilections have been identified in Feline CD?
- Several breed predispositions have been identified
- Suggests Genetic factors may play a role
- Over-grooming: Siamese, Burmese, Oriental cats
- Wool-sucking: Siamese, Birman, Crossbreed house cats
- Pica/Oral behavior: Bengal, Burmese-type, Siamese
When does Feline CD start?
- Mean age ~2 years
- Breeds that are predisposed to CD may exhibit signs at a younger age
- Mean age for wool-sucking in Siamese and Birman cats was 41.6 and 67.6 weeks
What is Feline overgrooming?
- Tends to be directed at:
- Abdomen
- Flanks
- Back
- Thorax
- Medial aspects of the thoracic limbs and thighs
- In some cases, excoriation of the underlying skin may be present
- Over-grooming in these areas is not pathognomonic for psychogenic alopecia
- Physical causes of over-grooming can result in the same pattern
What is Feline Pica behavior?
- Cats with Pica may chew on, suck on, or ingest various objects
- Pica may be directed at one or several objects
- Shoelaces
- Threads
- Plastic
- Fabric
- Rubber
- Paper
- Cardboard
- Wood
- Cats that suck on fabric are more likely to also ingest fabric
How is Feline CD diagnosed?
- Diagnosed by exclusion
- There could be a medical cause for the behavior
- After presumptive medical causes have been identified and treated, the repetitive behavior may persist to the same or lessor degree
- Can indicate that the physical ailment was either not the primary inciting factor OR
- Medical and behavioral comorbidities were present
- After presumptive medical causes have been identified and treated, the repetitive behavior may persist to the same or lessor degree
- Thorough behavior history
What should be gathered for history to diagnose Feline CD?
- Description (ideally including video) of the behavior
- Initiating factors situation in which the behavior is likely to occur
- Pet owner’s response
- Previous treatment attempts and their degree of success
What are the categories of Feline CD?
- Self-directed; Self-injurious
- Oral
- Locomotor
- Vocal
- Visual; Hallucinatory
What are the self-directed/self-injurious Feline Compulsive Behaviors?
- Overgrooming / Psychogenic alopecia
- Hyperesthesia Syndrome
- Feline Behavioral Ulcerative dermatitis
- Chewing feet/claws
- Feline orofacial pain syndrome
What are the Oral Feline compulsive behaviors?
- Pica
- Wool-sucking
What are the Locomotor Feline Compulsive disorders?
- Pacing
- Tail-chasing
- Hyperesthesia syndrome
What are the Vocal Compulsive Behaviors?
- Excessive vocalization
What are the Visual/hallucinatory compulsive Behaviors?
- Chasing unseen prey
How is Feline CD treated?
- Educating owners
- Minimizing the repetitive behavior
- Reinforcing alternative behavior
- Alleviating stress
- Environmental enrichment
- Anxiolytics
Should Negative punishment be used to treat Feline CD?
- NEVER use negative punishment
- Verbal or physical punishment
-
Repetitive behavior often originates from stress or frustration
- Use of harsh verbal or physical punishment that increases the cat’s anxiety
- May exacerbate the disease
-
Repetitive behavior often originates from stress or frustration
- Cats may learn to avoid punishment** and perform it **out of the owner’s sight
-
Use remote punishment that is not associated with the owner’s presence to stop CD behaviors
- Dropping a book to make a noise out of the cat’s sight
- Tossing a pillow across the cat’s line of sight to break its concentration
How can Minimizing the repetitive behavior affect Feline CD?
- Reduces opportunities for reinforcement of the behavior
- May be necessary for the health and welfare of the cats
- May increase stress in some instances
- Preventing situations that trigger the repetitive behavior or preemptively engaging the cat in another activity before the CD behavior occurs is ideal
- Attempts to distract the cat with food, toys, or attention while it is engaged in the repetitive behavior may inadvertently reinforce the behavior
How can reinforcing alternative behavior affect Feline CD?
- Positive reinforcement
- Teaches alternative behavior
- Creates pleasurable associations with previously stressful situations
How can stress be alleviated in cats with CD?
- Environmental Enrichment
- Anxiolytics
How can the environment be enriched for cats with CD?
- Feline environmental enrichment provides a means to:
- Avoid stressful situations
- Mental and physical stimulation
- Opportunities to engage in normal, species-typical behavior
What Anxiolytics are available for cats with CD?
- Pheromones (feline facial and appeasing)
- Supplements
- a-casozepine
- L-theanine
- Pharmaceuticals - response is highly variable
- TCA - clomipramine
- SSRI - Fluoxetine
- No FDA approved drugs for Feline CD
What is the prognosis for Feline CD?
- Fair for reduction in the frequency or intensity of CD behavior
- Poor for complete resolution or cure
- Owners should be informed that the goals of treatment are to improve the cat’s welfare and quality of life by:
- Limiting the risk for self-injury
- Increasing the amount of time engaged in pleasurable activities rather than the compulsive behavior
What additional considerations are there when treating Feline CD?
- Affects the well-being of both the cat and its owners
- May result in Relinquishment or Euthanasia of the pet if not addressed
- Ongoing communication with the owner is essential to increase the likelihood of compliance with the treatment plan
- Because treatment response depends on many factors nd may be unpredictable, Frequent consultation may be needed to adjust the treatment plan
