    Study Notes

    Neurological Disorders and Pathophysiology Summary

    • Alzheimer's disease is characterized by neurofibrillary tangles and amyloid plaques in the brain, not basal ganglia degeneration or aluminum deposits.
    • Before diagnosing Alzheimer's, other potential causes of dementia must be ruled out, and a brain biopsy is not necessary.
    • Parkinson's disease is caused by a deficiency of dopamine in the substantia nigra, not demyelination or insufficient acetylcholine production.
    • Dopamine precursors and anticholinergics are used in Parkinson's disease to increase dopamine activity in the basal ganglia, not to induce neuron regeneration or prevent progression.
    • Classic manifestations of Parkinson's disease include rest tremor and skeletal muscle rigidity, not intention tremor and akinesia.
    • Demyelinating disorders like multiple sclerosis slow down the conduction of nerve impulses, rather than facilitating or increasing the rate of conduction.
    • Steroids are used to manage acute exacerbations of multiple sclerosis symptoms by reducing edema and the inflammatory response, not inhibiting viral damage or reversing disease progression.
    • Upper extremity weakness associated with degeneration of CNS neurons is characteristic of amyotrophic lateral sclerosis, not multiple sclerosis, Guillain-Barré syndrome, or myasthenia gravis.
    • Ascending paralysis with no loss of sensation is characteristic of Guillain-Barré syndrome, not multiple sclerosis, myasthenia gravis, or amyotrophic lateral sclerosis.
