Study Notes

Neurological Assessment Overview

Focuses on understanding the anatomy and physiology of the nervous system.
Includes assessment of consciousness, cognitive functions, and physical examination.

Nervous System Arrangement

Central Nervous System (CNS): Comprises the brain and spinal cord.
Peripheral Nervous System (PNS): Encompasses cranial and spinal nerves, connecting the CNS to the rest of the body.

Brain Anatomy

Parietal Lobe: Responsible for spatial sense, navigation, and language processing.
Frontal Lobe: Involved in reward processing, short-term memory, planning, and motivation.
Cerebellum: Stores muscle memory; crucial for motor tasks, e.g., riding a bike.
Temporal Lobe: Processes speech, working memory, and emotions such as empathy and morality.
Occipital Lobe: Primarily responsible for visual processing.
Brain Stem & Midbrain: Regulates essential bodily functions like heart rate and digestion.
Limbic System: Involved in processing emotions and forming new memories through the hippocampus.

Common Brain Pathologies

Increased Intracranial Pressure (ICP) due to traumatic injuries or tumours.
Infections: Meningitis, encephalitis.
Ischaemic conditions: Ischaemic strokes, microvascular diseases (e.g., in diabetes).
Neurodegenerative disorders: Includes Alzheimer's disease, Parkinson's disease, and multiple sclerosis.
Cell death can lead to severe neurological impairment.

Blood-Brain Barrier (BBB)

A complex network of blood vessels supplying oxygen and nutrients to the brain.
Selectively regulates passage of substances, protecting the brain from infections.
Difficulty in treating brain infections due to large antibiotic molecules struggling to cross the BBB.

Monro-Kellie Hypothesis

Intracranial contents include blood, brain tissue, and cerebrospinal fluid (CSF) within a rigid skull.
Increased volume in one component raises ICP unless compensation occurs.
Mechanisms include:
- CSF regulation: Feedback adjusts CSF production based on pressure.
- Pressure autoregulation: Maintains stable cerebral blood flow through blood vessel adjustments.
- Metabolic regulation: Adjusts cerebral blood flow in response to CO2 levels, temperature, and acidity in the brain.

Level of Consciousness

Assessed on a continuum ranging from alert to coma.
Levels include:
- Alert: Fully responsive.
- Drowsy: Disorientated and retains some awareness.
- Stupor: Limited response to stimuli.
- Coma: Unresponsive to external stimuli.

Glasgow Coma Scale (GCS)

Developed by Jennet & Teasdale in 1977 for assessing impaired consciousness.
Assesses eye opening, verbal response, and motor response, providing an objective measurement of coma severity.
Used to triage patients and monitor consciousness trends in various medical situations.

Glasgow Coma Scale Scoring

Eye Opening: Ranges from spontaneous (4) to none (1).
Verbal Response: From oriented (5) to none (1).
Motor Response: From obeying commands (6) to no response (1).

Importance of GCS

Facilitates communication among clinicians regarding patient status.
Aids in determining severity of injury and required interventions.
