Study Notes
Neuropsychology Profession
- Neuropsychologists utilize knowledge from neurology, neuroscience, and psychology to understand the correlation between behavior and brain function.
- Often work clinically to diagnose conditions and make referrals for treatments.
- Some neuropsychologists are involved in research, investigating causes of disorders, brain-behavioral processes, diagnostic approaches, and treatment efficacy.
Brain Lesions and Function
- Brain lesions, caused by damage such as stroke, injury, or tumor, provide insights into brain function.
- Broca's aphasia, a condition caused by damage to a specific area of the brain, demonstrates the connection between brain damage and language impairment.
- Localization: Damage in a particular brain area suggests that specific functions are located anatomically.
- Lateralization: Damage to a specific side of the brain indicates that some functions are typically located on one side.
- Distribution of function: The brain's ability to compensate for lost functions suggests other areas can take over.
- Hierarchical organization: The complexity of functions differs depending on whether a higher or lower brain area is damaged, highlighting the brain's layered processing.
Principles of Organization
- Donald Hebb's Hebbian theory proposes that neural pathways develop and strengthen based on experience, emphasizing the brain's plasticity.
- Hebbian plasticity is a cornerstone of neuropsychology, recognizing the brain's ability to change and adapt, which is essential for understanding therapies and interventions.
Biopsychosocial Model
- The biopsychosocial model highlights social support, personal well-being, and environmental factors alongside biological aspects for a comprehensive understanding of health outcomes.
- The model helps in assessing and addressing psychosocial stressors that contribute to cognitive decline in conditions like dementia.
- The Neuropsychiatric Inventory (NPI) provides a standardized measure of dementia symptoms, including frequency, severity, and behavioral changes.
- Applying the Biopsychosocial model, neuropsychologists consider cultural context, beliefs about healthcare, and relationship to the healthcare system to provide culturally sensitive and holistic care.
Genetics and the Brain
- Epigenetics explains how experiences can influence heritable traits, bridging the gap between genetics and environment.
- Stress can lead to epigenetic changes and impact mental health over an individual's lifespan and across generations.
- Modern neuropsychology recognizes the interplay of genetics, epigenetics, and experience in shaping behavior and health outcomes.
The Neuron
- Neuropsychology relies on understanding the workings of neurons, the fundamental unit of the nervous system, to explore the basis of change within the brain.
- Understanding cellular processes aids in understanding the causes and mechanisms of numerous disorders, such as Multiple Sclerosis (MS).
Multiple Sclerosis (MS)
- MS is a heterogeneous condition, meaning symptoms and experiences vary based on factors such as lesion size, location, and the individual's brain organization.
- MS attacks the myelin sheath, which insulates nerve fibers, leading to a range of symptoms that affect motor function, sensory perception, cognitive processes, and emotional well-being.
- There are four types of MS: Primary progressive (PPMS), Relapsing remitting (RRMS), Progressive relapsing (PRMS), and Secondary progressive (SPMS), each having distinct symptom presentations and progression.
Key Points
- Phineas Gage's case demonstrated the localization of brain functions.
- Lesions can be caused by diverse factors like injury, blood flow problems, or cellular damage.
- The brain's capability to reorganize and compensate for lost functions is crucial for understanding treatment and recovery.
- Hebbian theory emphasizes the brain's ability to change, adaptability, and influence by experience.
- The biopsychosocial model integrates biological, psychological, and social factors to improve understanding and care delivery.
- Epigenetics underscores the impact of environment and experience on inherited traits.
- Neuropsychologists work in diverse settings, including clinical practice and research, to analyze and understand brain-behavior relationships.
