Study Notes
Neurological Examination Findings
- Anosmia is seen in Kallman syndrome due to olfactory bulb agenesis
- Patient tested for visual acuity with Rosenbaum chart, has 20/70 vision in left eye, 20/40 in right due to optic nerve damage
- Swinging flashlight test shows relative afferent pupillary defect in left eye
- Light-near dissociation occurs in Argyll-Robertson pupil, seen in neurosyphilis
- Patient shows right hemianopia from lesion behind optic chiasm
- Ocular myasthenia gravis patient has bilateral ptosis, ocular misalignment
- Patients with 6th and 3rd nerve palsies have incomplete eye movements and ptosis
- Patient lacks optokinetic nystagmus due to lesion of parietal-occipital gaze center
- Sensory deficit for both light touch and pain on left side of face for all divisions of 5th nerve
- Weakness of pterygoids causes jaw deviation, positive jaw jerk indicates upper motor lesion affecting 5th cranial nerve
- Patient has difficulty identifying taste on right side of tongue, indicating sensory limb lesion of 7th nerve
- Patient has conductive hearing loss in right ear, deficit of right 9th & 10th cranial nerves causes palate elevation and uvula deviation to left
