Neurology Quiz on Disorders

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.
