Study Notes
Introduction to Neurology
- Neurology is a medical speciality focusing on nervous system disorders. This includes the brain, spinal cord, nerves, and muscles.
- Neurologists understand nervous system structure and function, diagnosing and managing conditions.
- Neurological conditions range from common issues (headaches) to severe ones (multiple sclerosis, Alzheimer's).
Nervous System Structure and Function
- The nervous system has two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS).
- The CNS (brain and spinal cord) is the main control centre.
- The PNS is a network of nerves connecting the CNS to the body, enabling communication.
- Neurons are the basic units. They transmit information electrically and chemically.
Common Neurological Conditions
- Headaches and Migraines: Common complaints, caused by stress, tension, or underlying issues. Migraines are severe, throbbing headaches often with nausea and light/sound sensitivity.
- Seizures: Episodes of abnormal brain electrical activity, causing temporary neurological disruptions. Causes vary.
- Stroke: Impaired blood flow to a brain area, causing brain cell damage. Symptoms depend on location and extent of damage.
- Multiple Sclerosis (MS): A chronic autoimmune disease affecting nerve fiber myelin sheaths, causing mobility, sensation, balance, and vision problems.
- Parkinson's Disease: A neurodegenerative condition leading to tremors, rigidity, slow movements, and balance issues.
- Alzheimer's Disease: A progressive neurodegenerative disease causing mild memory loss, worsening over time.
Diagnostic Tools in Neurology
- Neurological Exam: Evaluating reflexes, muscle strength, coordination, and senses for diagnosis.
- Neuroimaging: CT, MRI, and PET scans visualize the brain and spinal cord, identifying structural issues and dysfunction.
- Electroencephalography (EEG): Measures brain electrical activity, diagnosing seizures, tumors, and other conditions.
- Electromyography (EMG): Measures muscle electrical activity, diagnosing muscle and nerve problems.
Treatment Approaches in Neurology
- Medication: Common to manage symptoms, slow disease progression, or prevent future episodes.
- Therapy: Physiotherapy, occupational, and speech therapy help recover or adapt abilities affected by neurological conditions.
- Surgery: Used for some conditions like brain tumors, blood vessel abnormalities, or spinal cord injuries.
- Alternative Therapies: Some explored, but often with limited scientific evidence.
Neurological Emergencies
- Stroke: Immediate diagnosis and treatment are crucial to limit brain damage and disability.
- Seizures: Treatment depends on the cause and frequency.
- Head Trauma: Urgent medical attention needed, often leading to long-term problems.
- Brain Tumors: Prompt diagnosis and treatment, depending on type and position.
Specific Neurological Disorders
- Amyotrophic Lateral Sclerosis (ALS): A progressive neurodegenerative disease impacting motor neurons, leading to muscle weakness and atrophy.
- Huntington's Disease: An inherited neurodegenerative condition causing uncontrolled movements, cognitive decline, and psychiatric issues.
- Epilepsy: A chronic neurological disorder with recurrent seizures.
Future Directions in Neurology
- Continued research into neurological causes.
- Development of new therapies (gene, stem cell).
- Improved diagnostic tools for earlier and more accurate diagnoses.
- More focus on preventative measures.
