Terms | Definitions |
|---|---|
 Weber test conductive hearing loss; sound lateralizes to? | side of affected ear |
| Weber test sensorineural hearing loss; sound lateralizes to? | side opposite of the affected ear |
| Rinne Test Normal Vs conductive hearing loss? | Normal AC greater than BC Conductive hearing loss BC greater than AC |
| Pt with Weber test result of midline; Rinne left ear AC > BC & right ear AC > BC; dx? | Normal |
| Pt with weber test result of right lateralization; Rinne left ear AC > BC & right ear BC > AC; dx? | Conductive hearing loss of Right Ear |
| Pt with weber test result of left lateralization; Rinne left ear AC > BC & right ear AC > BC; dx? | Right Sensorineural hearing loss |
| Pt with Weber test result of midline lat; Rinne Left ear BC > AC & Right BC > AC; dx? | Bilateral conductive hearing loss |
| Describe the light reflexes seen in both eyes if the right optic nerve is damaged prior to the pretectal nucleus (afferent defect)? | No constriction of either pupil when light is shined in right eye. Both pupils constrict if light is shined in left eye. |
| Describe light reflexes in both eyes if the right occulomotor nerve is damaged (efferent defect)? | Right eye will not respond to light shone in either R or L eye. Left eye will constrict when light is shined in either eye. |
| MS and internuclear ophthalmoplegia; what eye abnormality? | Internuclear Ophthalmoplegia |
| A pt cannot adduct her left eye on lateral gaze but convergence is normal; what structure is damaged? | Medial Longitudinal Fasciculus (MLF in internuclear ophthalmoplegia) |
| A light stimulus in pt's right eye produces bilateral pupillary constriction; when the lgiht is shown in the left eye there is a paradoxical bilateral pupillary dilation; what is the defect? | Afferent defect |
| What are the components of a dementia work up? | Cranial CT or MRI to rule out multi infarcts or stroke and to rule out normal pressure hydrocephalus. Screen for B12; TSH; HIV; and syphilis. Mini Mental Status Exam |

| Which neurodegenerative disease is a/w Lewy bodies? | Parkinsons Lewy body dementia (Diffuse lewy bodies) Alzheimers Diffuse lewy body type |
| Which neurodegenerative disease is a/w frequent falls and syncope? | Lewy Body Dementia |
| Which neurodegenerative disease is a/w atrophy of caudate nucleus leading to chorea? | Huntingtons |
| Which neurodegenerative disease is a/w depigmentation of the substantia nigra? | Parkinsons |
| Which neurodegenerative disease is a/w both upper and lower motor neuron signs (spasticity and weakness)? | ALS |
| Which neurodegenerative disease is a/w dementia and visual hallucinations? | Lewy Body Dementia |
| Which neurodegenerative disease is a/w Dementia and personality changes and/or aphasia? | Picks Disease |
| What neural pigment/inclusion is an intranuclear inclusion seen in herpes simplex encephalitis? | Caudry type A |
| What neural pigment/inclusion is a cytoplasmic inclusion pathognomonic of rabies? | Negri bodies |
| What neural pigment/inclusion is a neuronal inclusion characteristic of parkinsons? | Lewy body |
| What neural pigment/inclusion is a cytoplasmic inclusion body associated with aging? | Lipofuscin Granules |
| What neural pigment/inclusion is a dark cytoplasmic pigment in neurons of the substantia nigra and locus coeruleus; not seen in pts with parkinsons? | Melanin |
| What neural pigment/inclusion is eosinophilic, rodlike inclusions in hippocampus of Alzheimers pts? | Hirano Bodies |
| What neural pigment/inclusion is diagnostic of alzheimers? | Neurofibrillary plaques and tangles |
| What neural pigment/inclusion stain with silver, but do not survive neuronal death? | Pick Bodies |
| What neural pigment/inclusion stain with PAS and ubiquitin? | Lewy Bodies |
| What brain tumor is a/w polycythemia? | Hemangioblastoma |
| What brain tumor is a/w Neurofibromatosis II? | Schwanoma |
| What brain tumor is a/w Prolactinemia leading to galactorrhea, amenorrhea and anovulation? | Pituitary Adenoma |
| What brain tumor is a/w Psammoma bodies? | Meningioma |
| What brain tumor is a/w perivascular pseduorosettes? | Ependymoma |
| What brain tumor is a/w loss of peripheral vision or bitemporal hemianopia? | Pituitary Adenoma Craniopharyngioma |
| What brain tumor is a/w worst prognosis of any brain tumor? | Glioblastoma Multiforme |
| Differentiate partial, simple, complex and complete seizures? | Partial - localized to specific area of the brain Simple - no alteration of consciousness Complex - Alteration of consciousness Generalized - entire brain is affected |
| What are the most common causes of seizures in children? | Genetic Infection Trauma Congenital Metabolic disturbances |
| What is the classic triad in Multiple Sclerosis? | Charcot's Triad: Scanning Speech Intention Tremor Nystagmus |

| What allele is a/w Alzheimer's? | APP Apo E4 |
| Why is Alzheimers common in pts with Down Syndrome? | Bc chromosome 21 so these pts usually have three copies of APP gene |
