    Study Notes

    Neurological Case Studies

    • Case 1: A 40-year-old male presented with transient dysphagia, episodic headache, increased light sensitivity, and weakness on the left side of the body. Possible diagnosis needed.

    • Case 2: A 60-year-old female complained of a constant headache, worsening in the morning, and improving throughout the day. She had a history of intermittent visual disturbances and recent episodes of scalp tenderness. Her ESR was elevated. Likely diagnosis required.

    • Case 3: A 24-year-old female, Ms. Deepa, had a history of recurrent migraines without aura, diagnosed 12 months prior. She sought medical follow-up and to discuss treatment options, including preventative medications. Possible medications included amitriptyline, propranolol, sumatriptan, and ergotamine.

    • Case 4: A 28-year-old female presented with recurrent headaches described as throbbing, unilateral, accompanied by nausea, vomiting, and sensitivity to light and sound. Episodes typically lasted 4-72 hours and often preceded by auras. Likely diagnosis identified.

    • Case 5: A 35-year-old female with a history of recurrent, unilateral, throbbing headaches lasting 4-72 hours, and associated with nausea, vomiting, and photophobia. Often experiences auras before the headache. Likely diagnosis reported.

    • Case 6: A 40-year-old man presented with a sudden, severe headache described as the worst he'd experienced, localized around the neck and back of the head. He also reported nausea and photophobia, elevated blood pressure, and a stiff neck. Possible diagnosis noted.

    Neurological System Disorders (Pathology)

    • Autonomic Nervous System Disorders: Pathology of peripheral or central nervous system can result in autonomic nervous system disorders.

    • Upper Motor Neuron Lesion: Anterior horn cell disease, multiple sclerosis, prion disease, tuberous sclerosis are all types of upper motor neuron lesions.

    • Dystonia: A 30-year-old male presented with rapid, involuntary muscle contractions, causing repetitive movements (especially neck and shoulders), often worsening with stress. No history of trauma or neurological conditions. Likely diagnosis is dystonia.

    • Pseudotumor Cerebri: A condition caused by vitamin toxicity.

    • Upper Motor Neuron Lesion: All except anterior horn cell disease are examples.

    • Neurological diagnoses: Parkinson's disease, Huntington's disease, multiple sclerosis, amyotrophic lateral sclerosis (ALS), Wilson's disease.

    Additional Neurological Conditions and Treatments

    • Migraines: A 35-year-old male presented with chronic neck pain.
    • Headache Disorders: tension-type headache, migraine, cluster headache, sinus headache, temporal arteritis.
    • Vitamin toxicity: vitamin causes pseudotumor cerebri.
    • Treatment: options for managing migraines include medications like amitriptyline, propranolol, sumatriptan, and ergotamine.
