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.
