Study Notes

Course Introduction

Course title: Neurobiology, human behavior, and clinical neuroscience
Course structure: 19 CFUs (frontal) + 2 CFUs (clerkship)
Specialities covered: Neurology, Mental Health, Neurosurgery, Rehabilitation Medicine, Infant Neuropsychiatry, Pathology, Radiology, Pharmacology, Human Physiology, Anatomy, General Psychology, and Clinical Psychology
Examination: oral exams in Neurology and Mental Health; written multiple choice exam covering modules except Neurology, Mental Health, and Clinical Psychology with an additional open-ended essay for Clinical Psychology; asynchronous activity with graded clinical case reports

Neurological Examination

Essential tools: hammer, tuning fork/diapason, cotton bud, ophthalmoscope
Initial approach: observe patient's gait, posture, movements, presence of tremors, alertness, and general condition
Important to understand: symptoms, when they started—acute, subacute, or chronic—and any progression, associated symptoms
Questions to ask: any other medical history, family history of neurological illnesses, current medication, and any previous diagnoses
Prioritize understanding structural details of neurological disorders, especially common ones, rather than rare diseases

Cranial Nerves

Number of cranial nerves: 12
Cranial nerves are part of the peripheral nervous system, except for the optic nerve.
Testing methods: assessment of smell (olfactory), vision (optic), eye movements (oculomotor, trochlear, abducens), facial sensations (trigeminal), facial movements/expressions (facial), hearing and balance (vestibulocochlear), taste/tongue/pharynx (glossopharyngeal), visceral functions/GI tract/heart/lungs (vagus), neck and shoulder movements (accessory), and tongue movements (hypoglossal)
Importance of understanding specific pathways and associated muscles involved in cranial nerve functions like vision, facial expression, or eye movement.

Neurological Diseases

Main categories: cerebrovascular diseases (e.g., stroke), trauma, neoplasms (done by surgeons and pathologists), Epilepsy, headaches (not readily detectable), infectious diseases, inflammatory diseases (e.g., Multiple Sclerosis), degenerative neurological disorders (e.g., dementia, Parkinson's, ALS), developmental diseases, spinal cord diseases, and peripheral nerve diseases, and muscle diseases
Importance of recognizing symptoms, signs, and potential causes
