    Study Notes

    Pain Biopsychology

    • This course is on pain and biopsychology.
    • The presenter is Marla Joy Mierzejewski.
    • The course is at the University of Europe for Applied Sciences.

    Semester Schedule

    • Week 1: Introduction to the Central Nervous System (CNS). (October 28, 2024)
    • Week 2: Peripheral Nervous System and Neurons. (November 4, 2024)
    • Week 3: Drugs, Psychiatric Disorders, and Sensory System 1. (November 11, 2024)
    • Week 4: Sensory System 2, Movement, and Pain 1. (November 18, 2024)
    • Week 5: Pain 2, Immune System, and Stress. (November 25, 2024)
    • Week 6: Heart, Breath, and Hunger. (December 2, 2024)
    • Week 7: Sleep, Sexuality, and Genetics. (December 9, 2024)
    • Week 8: Methods and Recap. (December 16, 2024)

    Recap

    • Sensory systems: Visual, auditory, olfactory, gustatory, and haptic.
    • Motor system: Basal ganglia, cerebellum, thalamus, brainstem, and spinal cord.
    • Pain: Acute vs. chronic pain, pain diagnostics, neuroplasticity, and biofeedback.

    Research

    • Research in groups of 4-5 on how pain sensation and processing works.
    • Research on nociceptors and their role.
    • Research on brain areas essential for pain processing.
    • Report findings within 10 minutes.

    Pain Conduction

    • Nociceptors perceive thermal, chemical, or mechanical stimuli potentially harmful.
    • Nociceptors are not pain receptors.
    • Stimuli trigger signals to spinal cord - >thalamus.
    • Thalamus filters information, passing it on to lateral and medial systems and frontal cortex.
    • Lateral system relays conscious pain perception to somatosensory cortex.
    • Medial system processes pain's affective and subjective meanings through limbic system.
    • Frontal cortex processes memories and experiences related to pain.

    Chronic Pain Risk Factors

    • Current stressors (work, family).
    • Operant reinforcement (leads to stronger pain behaviors).
    • Operant mechanisms (related to medication intake and activity design).
    • Model learning.
    • Attention processes.
    • Iatrogenic influences: Over-diagnostics, incorrect information (rest, bed rest), or incorrect medication.
    • First learning processes at the level of the posterior horn; Cerebral changes in the form of expanded representations in the somatosensory cortex, leading to somatosensory "pain memory".

    Chronic Pain definition (Temporal, Spatial & Behavioral)

    • Temporal: Intermittent (stage 1), continuous (stage 2), highly changing intensity (stage 3).
    • Spatial/Localization: Limited to time / paraphrased (stage 1), extended to neighboring areas (stage 2/3).
    • Behavioral: Adequate medication, doctor consultations, hospital/surgery (stage 1), partly abuse of medicines, change of doctor, hospital/surgery (stage 2-3)

    Pain Disorder in ICD-10 & -11

    • ICD-10 F45.4: Persistent pain disorder (at least 6 months of severe pain).
    • ICD-11 MG30: Chronic pain. Primary pain (visceral, widespread, musculoskeletal, headache, orofacial), cancer related, postsurgical/post traumatic, secondary musculoskeletal, visceral, or neuropathic pain.
    • Psychological and social factors influence chronic pain.
    • Symptoms, Signs, or Clinical Findings (chronic pain, associated emotional distress, and functional disability) affect appropriate diagnoses.

    Phantom Limb

    • Pain that occurs in an amputated body part.
    • Characterized by tingling sensations, touch and warmth/cold.
    • Related to changes in the brain's nervous system (functional reorganization of somatosensory cortex; internal representation remains intact).
    • Damaged neurons form neuroma and generate action potentials.

    Pain Therapy

    • Acute pain: Tablets, pain pumps, appropriate activity and physiotherapy are used.
    • Phantom pain: Medication, prosthesis, and mirror therapy are used.
    • Chronic pain: Electromyography biofeedback, physiotherapy, relaxation method, cognitive behavioral therapy, imagination, and mindfulness are used.

    Immune System

    • Brainstorming topics: Immune system function; Composition of the immune system; Influence of the immune system; Problems with malfunctioning.
    • Reading material: Innate and adaptive immune systems and associated questions.
    • Study topics: Protective function, Innate immune system, Adaptive immune system.

    Immune System and Vaccination

    • Principle of vaccination: Injection of killed or weakened pathogens.
    • Immune response: Body reacts by producing antibodies and memory cells to prepare for real pathogen encounter.
    • Covid-19 and Vaccination: The vaccination against Covid-19 generates an immune response, reducing the chance of severe illness and death, and minimizes chances of spreading the virus.

    Immune System - Infection vs. Vaccination & Measles

    • Measles: High infectivity, epidemic risk, potential serious consequences from infection, as opposed to vaccination.
    • Research (in groups of 4-5) should be done on the correlation between measles vaccination and autism in the U.S.

    Disorders of the Immune System

    • Primary immune deficiencies: Born with a weak immune system.
    • Acquired immune deficiencies: Resulting from a disease or medicine that weakens the immune system.
    • Overactive immune systems: Can cause allergic reactions (rhinitis, asthma, eczema).
    • Autoimmune disorders: Immune system attacks the body's own cells (type 1 diabetes, rheumatoid arthritis).

    Stress

    • Brainstorming topics: Identifying stressors; How to recognize stress; Discussion within small groups.
    • Stress definition: Body reactants with physiological change in response to stressor.
    • Stress definition – biological: Fight or flight response, General Adaptation Syndrome, and Allostatic Load.
    • Stress definition – psychological: Critical Life Events, Transactional stress theory, Theory of Resource Conservation.
    • Stress components: Stressor (environmental stimulus), Detection of threat (unconscious/conscious), Stress response (activation of various biological systems).
    • Stress Location in the Brain: Hypothalamic-pituitary-adrenocortical axis (HPA axis); Corticotropin releasing hormone (CRH), Adrenocorticotropic hormone (ACTH), and Cortisol.
    • Stress and allostatic load: Allostasis, the body’s ability to adapt and maintain homeostasis during a stress response. Allostatic load represents consequences of the constant adaptation, damage to the body due to long-term stress exposure, or inefficient system response.

    Immune System & Stress

    • Short-term stress has a positive effect; Long-term stress weakens the immune system.
    • Chronic stress, elevated cortisol levels and increased vulnerability to infections.
    • Stress can reduce the number of natural killer cells and influence T- and B-lymphocytes.
    • Communication/interactions between nervous system and immune system are relevant.
    • Hippocampus is vulnerable to stress.
    • More research is needed.

    Research Topics

    • Stress role in disease development (in groups of 4-5).
    • HPA axis and the functions of CRH, ACTH, and Cortisol (in groups of 4–5).
