Study Notes
Trigeminal Neuralgia (Tic Douloureux)
- Results from degenerative changes or compression of the trigeminal nerve (Cranial Nerve V).
- Characterized by intense, sharp pain along the nerve distribution.
Bell’s Palsy
- Caused by inflammation of Cranial Nerve VII, typically from viral or bacterial infection or trauma.
- Symptoms include temporary facial paralysis, loss of facial expression muscles, eye tearing, drooling, and headaches.
Alzheimer’s Disease
- A progressive degenerative condition affecting the cerebral cortex, leading to neuronal degeneration and neurotransmitter loss.
- Signs include memory loss, dementia, disorientation, confusion, irritability, personality changes, and speech deterioration.
Amyotrophic Lateral Sclerosis (ALS)
- A progressive degenerative disease impacting motor neurons in cranial and spinal nerves, potentially linked to genetic and environmental factors.
- Symptoms comprise muscle spasms, cramps, fatigue, slurred speech, difficulty swallowing, and eventual paralysis and breathing issues.
Cerebral Palsy
- A non-progressive motor function disorder caused by brain damage before or during birth, from infection, trauma, or toxic conditions.
- Symptoms include impaired speech and walking, muscle spasms, and spastic paralysis.
Cerebrovascular Accident (CVA)
- Occurs due to interruption of blood flow to the brain, resulting in ischemia and tissue necrosis. Can be ischemic (thrombosis or embolism) or hemorrhagic.
- Symptoms include unilateral numbness and paralysis, slurred speech, aphasia, muscle weakness, mental confusion, visual impairments, and potential coma or death.
Epilepsy
- Characterized by abnormal electrical impulses in the brain leading to seizures, linked to brain injuries, tumors, infections, or metabolic issues.
- Signs include nausea, visual disturbances, altered tastes and smells, loss of consciousness, muscle tremors, convulsions, and sensory loss.
Encephalitis
- Inflammation of the brain, often triggered by viral infections.
- Symptoms range from fever, headache, lethargy, delirium, to seizures and potential brain damage, coma, or death.
Huntington’s Disease
- A hereditary disorder causing neuronal degeneration in the brain, resulting from an autosomal dominant defect on chromosome 4.
- Signs include muscle rigidity, mental health changes, depression, dystonia, ataxia, chorea movements, swallowing difficulty, and dementia.
Parkinson’s Disease
- A neurodegenerative disease affecting motor neurons, particularly in the substantia nigra where dopamine production is impaired.
- Symptoms consist of resting tremors, decreased movement speed, slow speech, coordination challenges, shuffling gait, and a mask-like facial expression.
Meningitis
- Inflammation of the meninges, often due to viral or bacterial infections.
- Common symptoms include fever, headache, neck stiffness, confusion, vomiting, and severe neurological issues if caused by bacteria.
Poliomyelitis
- An infection of the spinal cord's gray matter caused by poliovirus, leading to inflammation.
- Symptoms include paralysis, muscle atrophy, respiratory failure, and potential infections affecting the digestive and respiratory systems.
Astigmatism
- Results from abnormal curvature of the lens, causing irregular light bending.
- Symptoms include blurred or distorted vision.
Myopia
- A refractive error where elongated eyeball shape leads to difficulty in seeing distant objects clearly.
- Commonly referred to as nearsightedness.
Hyperopia
- Caused by a shortened eyeball shape, resulting in difficulty seeing close objects clearly.
- Commonly referred to as farsightedness.
Nyctalopia
- Also known as night blindness, can occur from vitamin A deficiency or retinal degeneration.
- Symptoms include difficulty seeing in low light or darkness.
Conjunctivitis
- Inflammation of the conjunctiva usually caused by infections, either viral or bacterial.
- Signs include redness, itching, and discharge, and it is highly contagious.
Strabismus
- Characterized by the misalignment of eyes due to inherited factors or trauma.
- Types include convergent (medial) and divergent (lateral) deviations.
Glaucoma
- Increased intraocular pressure from excessive aqueous humor can lead to optic nerve damage.
- Symptoms include visual field loss and potential blindness if untreated.
Cataracts
- Cloudiness in vision from calcium buildup in the lens or cornea, often associated with aging or medication.
- Symptoms manifest as foggy or blurred vision.
Tinnitus
- A condition characterized by ringing in the ears, caused by injury, infection, otosclerosis, or age-related issues.
- Symptoms include persistent ringing, buzzing, or other auditory noises.
Otitis Media vs. Otitis Interna
- Otitis Media: Middle ear infection usually following upper respiratory infections. Symptoms include ear pain, inflammation, and fever, more prevalent in children.
- Otitis Interna: Involves inner ear inflammation typically resulting from infections, leading to more complex symptoms.
