Q
Neuroleptic
A
*Antipsychotics are often referred to as “neuroleptics” especially (but not exclusively) the typical, 1st generation drugs like thorazine, mellaril, halloo, navane, prolix, etc.
13
Q
Neurolepsis (Contd…..)
A
- In the early literature the drugs were said to cause “neuroleptic”, characterized by 3 major behavioral effects:
- Psychomotor slowing
- Emotional quieting
- Affective indifference
14
Q
Phenothiazines
A
- Most typical antipsychotics are phenothiazines - a name for a type of chemical structure

18
Q
EPS and Typical Antipsychotics
A
- Extra-Pyramidal signs & symptoms
- These side effects are most often associated with typical antipsychotics, likely due to the relationship with dopamine (specifically the D2 receptor)
19
Q
EPS and Typical Antipsychotics
Contd…
A
- However, recent studies indicate that A-typical antipsychotics Also show a higher incidence of these side effects than initially suspected, especially with long term use. (D2 also & Serotonin)
- Also some atypical (e.g. Risperadal or Zyprexa) may show higher incidence than others (Clozapine, Seroquel)

34
Addictive Potential
* Benzodiazepines are considered to have a very high potential for addiction & it can happen quickly, or almost certainly occur over extended use
- Thus missed doses can result in behavioral episodes
- Rapid Tolerance: can develop rapidly esp to hypnotic effects of medication, may lead to taking higher doses
35
Benzos & Alcohol
* This can be lethal combination
* Both metabolic & dis-inhibitory effects combine & lead to overdose & death
* Bx analysts working with individuals who seek out alcohol in the community must be sure the prescribing physician is fully informed
36
Other issues
* Cognitive impairment: esp problematic with elderly patients who are at high risk for falls/hip fractures
* Chronic use results in lengthy withdrawal effects, including months of anxiety, depression, insomnia, gastrointestinal prob
37
Likely Functions Related to Anxiety
* All functions are in play as always, but the likely functional relations inherent in anxiety-related Bx are:
1) Escape/ Avoidance (esp avoidance)
2) Respondent conditioning (e.g. phobias)
38
Anxiety as a Cause of BX?
- This is a classic explanatory fiction
- But calling it that is probably why ppl do not usually come to us to seek relief for their anxiety!
- We need to change this
39
Anxiety & BX Analysis
* Bx analysts must operationalize those target responses that are agreed upon as "Anxiety" by both individuals seeking treatment & the medical professionals who manage medication
- We then collect data on Those targets
40
Measurement Tools
- While data maybe collected by observers on external responses such as Pacing, Refusals to go out, Running away, hyperventilating Confusion etc., "Anxiety" is typically experienced as a pvt event
- Thus, self-reporting is helpful, esp during assessment (for individuals with verbal repertoires)
41
Treatments
- Everyone is different, but besides anxiolytic drugs...
- Systematic desensitization (related to anxiety producing situations)
- Teaching other relaxation techniques
- Search the literature for more
42
Other Concerns Related to Anxiolytics & Behavior Analysis
- Anxiolytics work, initially
- They have very low toxicity
- But btw addiction potential, tolerance, paradoxical side effects & withdrawal effects, anxiolytics can actually result in an increase anxiety responses over time
43
Other Concerns Related to Anxiolytics & BX analysis
| contd
*Add to these prob the issues of potential lethality when some of the most common anxiolytic are combined with alcohol or other drugs of abuse potential (e.g. opioids)
44
Bx Analysis & Anxiety
*One way or the other with/without medication, Bx analysis is necessary in the treatment of anxiety
45

50
Its All in The Name
* Welbutrin Vs Zyban
* An excellent e.g. of main effects Vs. side effects
* For Welbutrin, the main effect is as an antidepressant, the side effect is the reduction of addictive urges
* For Zyban, just the opposite is true
51
Anti-depressants and Therapeutic Effects
*For many anti-depressants there is a time delay btw when the drug is first taken & when therapeutic effects are detectible......
52
Antidepressants: Delayed Effects
- Newer anti-depressants (e.g. SSRIs) take many days to reach a therapeutic level in the blood
- Clinical improvement maybe delayed by 2 weals/more as the medication takes effect slowly
- This reduces their abuse potential, since they are not immediately reinforcing
53
Behavior Analysis & Depression
- Many of the same points made in the section on Bx analysis & anxiety pertain to depression as well
- Depression is not a cause of Bx, but a category of behavioral responses that can be operationalized
54
Depression and Medication
* Studies are quite mixed on the efficacy of anti-depressant medication in changing Bx related to most types of depression
* The Bx analyst MUST be involved in tracking target behaviors, operationalized as markers of depression & charting those data
55

56

57

a) True
b) False
a) True
58
Charlott's Web Oil Update
-In Nov of 2014, Gov. Rick Scott of Florida signed a bill legalizing of the use of Charlotte's web oil for both seizures in children and other medical uses
59
Seizures and Behavior Analysis
| *Seizure activity in an individual is imp for Bx analysis services for 5 main reasons
1) Bx before the Seizure
2) Bx during the seizure
3) Bx after the seizure
4) Staff training related to seizures
5) Tracking medication effectiveness
60
Behavior Before the Seizure
* The BX analyst maybe able to help identify behavioral signs of the onset of a seizure
* The Bx analyst maybe able to help the individual identity & recognize "aura" signs that a seizure episode maybe about to begin
61
Behavior During the Seizure
* There are many types of Seizures
* Most involve Tonic/Clonic involuntary movements ("Grand Mal"), or brief periods of "absence"
* Caregivers must be trained to recognize & track these episodes, by collecting "seizure data"
62
Atonic Seizures and Protective Devices
* Atonic Seizures, where muscle control is totally lost and during which an individual can simply drop to the floor without warning, poses a safety hazard to the individual (e.g., head injuries when failing)
* Helmets or other safety devices maybe needed, & usually a Bx analyst is involved in training and tracking these interventions
63
Frontal and Temporal Lobe Seizures
- Some literature indicates temporal lobe (or frontal lobe) seizure activity maybe tied to aggressive/violent Bx
- As such, this Bx may or may not be good candidate for behavioral intervention. The Bx analyst must assess this
64
Behavior After the Seizure
- Often right after a seizure, the individual is tired, irritable, not talkative & otherwise exhibiting a different behavioral profile than usual
- Efficient learning maybe temporarily compromised
- Automatonisms (robot-like responses after a seizure) maybe mistaken for a Bx prob - these must be behaviorally assessed
65
Seizure-related Behavior
- These & other patterns of responding may not be under full operant control - or may at the very least be functionally related to the physical act of having gone through a seizure
- Bx analysts are responsible for training caregivers how to respond to these types of post-seizure behaviors
66
Staff Training re: Seizures
*Staff must be trained on all 3 of these phases: what to do before a seizure if one is identified as coming: what to do during a seizure, including special medication administration for rapidly cycling & high freq seizure activity (usually per rectal)
67
Taking Medication Effectiveness
- Seizures can be counted and times, and data maybe collected on those events. Each can be a condition line
- Frequency/duration charts on seizure-based bx provide an imp tool for determine the effectiveness of a particular does of a particular drug (or drugs)
