When assessing memory at the bedside, we are examining 4 subtypes of memory: immediate memory, working memory, recent memory, and remote memory. The most common presentations in the clinical setting are mild cognitive impairment, Alzheimer disease, vascular dementia, dementia with Lewy bodies, Wernicke-Korsakoff syndrome, and chronic traumatic encephalopathy. Abnormal markers of both amyloid and tau are necessary for the occurrence of the accelerated neurodegeneration and memory loss that precedes Alzheimer disease.

Drop attacks are sudden falls without loss of consciousness that are not precipitated by a specific stimulus, occur with abrupt onset and without warning, and are followed by a rapid return to baseline. A range of localizations for drop attacks is possible, but most commonly lower brainstem or spinal cord structures are implicated. Drop attacks generally indicate transient impairment of bilateral CNS structures involved in maintenance of postural muscle tone and balance.

Stenosis of the lumbar spinal canal is most commonly associated with multilevel degenerative spine disease, although commonly worst at the L4-5 level. Neurogenic claudication is classically described as a poorly localized sense of discomfort and aching pain in the lower back, buttocks, and legs, precipitated by walking and relieved by sitting. Patients may experience numbness or deadness of the limbs, paresthesias, or subjective weakness that is usually bilateral and asymmetric.
