Document Summary
Neurological: the neurologist is interested in ascertaining the functional and anatomical integrity of the central nervous system. Limited in the ability to say much about causation about behavioral or cognitive impairments. Methods of investigating the brain are rather limited in scope: engage the patient in neurological assessment. E. g. , cranial nerves, strength and tome of muscle groups. Screen for neurological impairment but do not diagnose neurocognitive impairment: looking for patterns indicative of neuropathology that are used for diagnostic purposes, to guide medical intervention and/or monitor the status of a known condition, limitations of neurological exam: Only extreme poles considered on continuum, middle is grey area. Structural neuroimaging: prior to the 1970"s, imaging of the brain was not available. Simple x-ray technology only reveals the structural integrity of more dense structures (i. e. , bones). (hence the need for the most basic neuropsychological tests): since the 1970"s, a refinement of x-ray technology, computerized tomography (ct), developed.
