Study Notes

Language vs. Communication

Language is a sophisticated system of communication, unique to humans, distinguishing them from animals.
Communication exists in both humans and animals, but language is a distinct human trait.

Language vs. Speech

Speech refers to the verbal expression of language involving neuromuscular programming, articulation, voice, and fluency.
Language consists of socially shared rules affecting semantics, morphology, syntax, grammar, and pragmatics, relying on cognitive processes.

Basics of the Nervous System

Central Nervous System (CNS) encompasses the brain, spinal cord, and brainstem, crucial for cognitive communication functions.
Peripheral Nervous System (PNS) includes cranial and spinal nerves, responsible for motor, sensory, and autonomic functions.
CNS is safeguarded by bony structures, meninges, and cerebrospinal fluid.

Cell Types in the Nervous System

Neurons include dendrites, cell bodies, axons, and synapses, essential for transmitting signals.
Glial cells support neurons and provide myelination of axons.
Gray matter represents neuronal cell bodies and dendrites; it appears on the brain's surface.
White matter consists of myelinated axons found deeper within the brain, often referred to as tracts or fasciculi.

Divisions of the Central Nervous System

Left Hemisphere is vital for language production and comprehension.
Right Hemisphere processes spatial aspects, melody, and intonation.
Four main lobes:
- Frontal: executive functions, decision-making.
- Parietal: sensory perception.
- Temporal: auditory processing and memory.
- Occipital: visual processing.

Brain Functional Areas

Brodmann’s areas are regions in the cortex associated with specific functions.
Primary Cortex perceives stimuli, while Association Cortex interprets and recognizes information.
Types of white matter tracts:
- Projection tracts connect primary cortical areas with deeper structures.
- Association tracts connect regions within the same hemisphere.
- Commissural tracts connect equivalent areas in both hemispheres.

Blood Supply to the Brain

Continuous blood flow is critical for brain cell function to avoid cell death.
Major cerebral arteries include:
- Anterior Cerebral Artery (ACA): supplies blood to the prefrontal cortex.
- Middle Cerebral Artery (MCA): supplies blood to language centers in the left hemisphere.
- Posterior Cerebral Artery (PCA): supplies the occipital lobe.

Types of Stroke

Ischemic strokes result from blocked arteries and include:
- Transient Ischemic Attack (TIA): temporary symptoms resolving quickly.
- Thrombosis: localized plaque buildup causing a blockage.
- Embolism: blockage caused by a traveling clot.
Hemorrhagic strokes result from bleeding in or around the brain:
- Intracerebral: bleeding within brain tissue.
- Extracerebral: bleeding within the meninges.

Neuroimaging

Structural neuroimaging assesses brain anatomy in vivo, using techniques like CT and MRI to differentiate between stroke types.
Functional neuroimaging studies neural activity during specific tasks, utilizing methods like PET and fMRI.

Statistics on Neural Injury

Approximately 795,000 strokes occur in the U.S. annually, leading to significant economic and health impacts.
Traumatic Brain Injury (TBI) affects about 2.5 million people each year, with children and the elderly being the most vulnerable.
Alzheimer's Disease affects 5 million people and is a leading cause of death.

Interventions aim to restore function and enhance everyday life quality based on individual significance.
Definitions of health have evolved, emphasizing overall well-being (WHO).

Coping and Recovery

Family dynamics, financial stability, and social integration significantly influence recovery.
Advances in rehabilitation focus on neuroplasticity and adapting therapy to enhance healthy tissue functionality.
Patient-centered approaches prioritize communication, empathy, and collaboration during recovery.

Comorbidity of Mood Disorders

Depression is common among individuals with brain injury, impacting quality of life.
Current treatment strategies advocate for immediate intervention rather than delayed observation.

Chronicity of Illness

Chronic illness is characterized by prolonged duration, with emotional responses documented in stages (shock, denial, mourning, adaptation).

Quality of Life Assessment

QoL assessments evaluate physical, psychological, and social dimensions to inform care plans and interventions.
