Stress : Managing And Coping With Stress Flashcards
What are drug therapies
Can offer some effective relief from stress-related anxiety.
What is Benzodiazepines
Such as Valium increase the activity of the neurotransmitter GABA, which decreases serotonin activity. As serotonin is linked to arousal , low serotonin activity reduces arousal , thus reducing stress
What are beta blockers?
- Beta blockers act directly on the sympathetic nervous system and so reduce the arousal of the “fight or flight” response of the SAM axis and HPA axis, by acting on the CNS and ANS.
- They reduce heart rate and lower blood pressure, which are symptoms associated with stress, and act on the body not the brain.
- Beta-blockers reduce the responsiveness of the sympathetic ganglia and nerves.
What is the pathway for managing stress with drugs -(biological methods)
Benzodiazepines (BZs)
-> Most common drug to treat stress and anxiety
-> Slows down the CNS activity
-> GABA is the neurotransmitter responsible for anxiety relief naturally in the body.
-> 40% of neurons in brain respond to GABA -> BZs enhance GABA -> BZs also reduce the serotonin activity in the brain as this is the neurotransmitter which causes the arousal; this also reduces anxiety.
What can stress cause?
Stress causes an arousal of the sympathetic nervous system (SNS) and this can lead to: - raised blood pressure
- increased heart rate
- elevated levels of cortisol
These then can cause:
- cardiovascular disorders
- reduction in the effectiveness of the immune system
What do beta blockers achieve?
- By blocking these receptors, it is harder to stimulate the cells.
- An example would be the heart; it begins to beat slower and with less force so blood vessels do not contract easily. This then leads to a fall in blood pressure which in turn means less stress on the heart. The person would begin to feel calmer and less anxious
Strengths of Drug Therapy?
- Drugs are effective
- By comparing drugs to placebos you can see if the drug has pharmacological or psychological effects.
- Kahn et al (1986) used 250 participants over 8 weeks. Found that BZs were superior to a placebo.
- BZs have been found to be better than other antidepressants.
- Beta blockers are useful in real-life situations where accuracy is more important than stamina (e.g. golf and snooker).
- Drugs are easy to use.
- Require little effort compared to psychological methods (e.g. SIT).
Limitations of drug therapy?
- BZs are addictive even in low doses.
- Using BZs results in withdrawal symptoms.
-Ashton (1997) recommends taking them for no more than 4 weeks. - Side-effects of BZs include aggressiveness and cognitive impairment (e.g. the ability to store new knowledge in LTM is reduced).
- Some studies have linked BBs to diabetes.
- The effects of drugs last only as long as they are taken; the effectiveness stops when the drugs are stopped.
- If the problem has not passed then the individual’s problem could return, along with addictive side-effects. A psychological method may be recommended at the same time.
Evaluation of Physiological Methods of Stress Management ( Beta-Blockers )
Beta - Blockers :
• Quick and effective way of reducing dangerous symptoms such as high blood pressure
• They do not produce harmful side effects.
• They only reduce the physical symptoms of stress; they do not deal with the source of that stress.
• Therefore, they are not a long-term solution.
Evaluation of Physiological Methods of Stress Management ( Benzodiazepines)
- Relatively easy to prescribe and use help to relieve the symptoms associated with stress such as a lack of sleep
• However, these drugs only help with the symptoms and only so long as the drugs are taken.
• BZ’s can have minor side effects such as dizziness and tiredness or more serious effects such as blurred vision and changes in sex drive.
• Another major problem with these drugs is that they can become addictive. Therefore, patients may experience withdrawal symptoms such as increased anxiety, seizures, tremors and headaches when they come off the medication, which can be distressing.
• Such issues give rise to ethical concerns regarding the prescription and management of such treatments and whether or not patients who are experiencing high levels of stress and anxiety are able to give fully informed consent.
What is Biofeedback?
Biofeedback involves the individual being connected to a machine that provides feedback (visual or auditory) on ANS arousal/signs of stress e.g. heart rate, muscular tension etc.
Heart rate is usually measured and feedback will indicate if it is too high or OK.
They use the feedback try and alter their own heart rate, breathing etc.
What steps can a Person learns how to control and regulate symptoms of stress?
- 1.electro codes are attached to your skin. Person attached to machine that monitors and gives feedback on heart rate
- 2.They then send information to a monitoring box which translates measurements onto a computer screen.
- Person is taught relaxation techniques reducing the activity of the SNS and activate the parasympathetic nervous system, slowing heart rate and makes them feel relaxed. This means that adrenaline and noradrenaline are no longer produced, this results in reduced heart rate, blood pressure and all other symptoms associated with stress.
- 4.Relaxation acts like reward and encourages person to repeat this involuntarily-Person learns to use it in
real-life situations
What are the Biofeedback steps?
Learning to control ANS/involuntary body activities:
Feedback: Patient connected to a machine that provides
information about ANS activity.
Relaxation: Learn to control ANS.
Operant conditioning: Successful behaviours are repeated because they are rewarding.
Transfer to everyday situations.
Research into biofeedback?
Lemaire et al (2011) found that doctors who were taught biofeedback techniques and used them over 28 days reported much more reduced levels of stress (measured through a questionnaire) than a control group, supporting the effectiveness of biofeedback in managing stress.
But also measured the physiological symptoms of stress, such as heart rate and blood pressure, in the same participants, and found no significant changes over the 28-day period.
These findings weaken the use of biofeedback, as the effect on the physiological effect of stress seem to be very limited, or non-existent
What is Budzynski research?
Budzynski et al conducted research into the effectiveness of biofeedback as a way of treating tension headaches.
He assigned 18 participants into 3 groups of six. Group A had biofeedback sessions,
Group B were taught relaxation techniques
Group C were a control who received no intervention.
Group A reported a significant decrease in headaches; this shows biofeedback can be effective
