Study Notes

Neurology Overview

Neurologists specialize in diagnosing and treating neurological disorders including strokes, movement disorders, neurodegenerative diseases, seizure disorders, and infections affecting the brain and nervous system.
Stroke: Medical condition caused by inadequate blood flow to the brain leading to cell death; characterized by symptoms such as facial drooping, arm weakness, and speech difficulties.
- Types:
  - Ischemic stroke: Most common, caused by blood clot blocking circulation.
  - Hemorrhagic stroke: Caused by bleeding due to ruptured vessels.
Symptoms of stroke include dizziness, loss of vision on one side, inability to move or feel on one side, and sudden speech problems.

Meningitis

Meningitis refers to the inflammation of membranes surrounding the brain and spinal cord; can be viral (most common) or bacterial (more severe).
Symptoms include sudden high fever, neck stiffness, light sensitivity, sleepiness, and potential complications like hearing loss and brain damage.

The Brain

Situated in the head and protected by the skull; crucial for intelligence, movement initiation, behavior control, and sensory interpretation.
Key parts of the brain:
- Cerebrum: Largest part responsible for processes like speech, emotion, and learning.
- Cerebellum: Coordinates muscle movements and maintains posture.
- Brain Stem: Controls automatic functions (breathing, heart rate, etc.).

The Pituitary Gland

Master gland that regulates other glands through hormone secretion, impacting growth, metabolism, and reproduction.

Neurons and Glial Cells

Neurons: Specialized cells composed of axons, integral to the nervous system's functionality.
Symptoms of serious conditions include skin rash, nausea, severe headaches, and seizures, particularly in individuals with weakened immune systems or children.

Traumatic Head Injuries

Commonly caused by accidents; symptoms include headaches, nausea, dizziness, confusion, and sensory changes (blurry vision, sensitivity to light).
Concussions can result from various types of trauma, often requiring emergency care.

Radiology

Specializes in diagnostic imaging techniques including X-rays, CT scans, MRI, and PET scans to visualize brain conditions.

Neurodegenerative Disorders

Alzheimer’s Disease: Most common type of dementia, characterized by progressive memory loss and brain shrinkage due to protein aggregation leading to neuron death.
Parkinson’s Disease: A brain disorder leading to uncontrollable movements, stiffness, and coordination issues, with gradual symptom onset and worsening over time.

Psychiatry

This branch of medicine addresses mental health disorders such as schizophrenia, depression, addiction, and bipolar disorder.
Psychiatrists are medical doctors who can prescribe medication; psychologists focus on behavioral therapy without medication prescribing capabilities.

The Mouth and Oral Cavity

Initial part of the digestive system; digestion starts here with teeth, saliva, and the tongue aiding in breaking down food.

Maxillofacial Surgery

Involves procedures for facial trauma, reconstruction, cosmetic surgery, and surgery of the oral cavity, including cleft lip and palate repair.

The Thyroid Gland

Butterfly-shaped gland in the neck that secretes hormones (T3, T4, and peptide hormone) influencing metabolism, growth, and development in children.
Conditions affecting the thyroid include congenital iodine deficiency syndrome and hypothyroidism, commonly resulting from iodine deficiency during pregnancy.
