As predicted, baseline comparisons among the three half of relatives who live to the age at riskwill develop AD.

At mental rest, younger and Regional decreases in perfusion in patients whose diagnosis 1238 Neuropsychopharmacology: The Fifth Generation of Progress converted to AD were most prominent in the hippocampal- amygdaloid complex, the anterior and posterior cingulate, and the anterior thalamus. A direct comparison of FDG PET and HMPAO-SPECT in their ability to differentiate AD from vascular dementia indicated higher diagnostic accuracy for PET regardless of dementia severity (98). Using ROC curves, PET diagnostic accuracy was better than SPECT for an MMSE score greater than 20 (87. Other studies confirmed a lower sensitivity for even high-resolution SPECT compared with PET (99). Moreover, the parietal hypoperfusion observed using SPECT in patients with AD has been observed in such other conditions as normal aging, vascular dementia, posthypoxic dementia, and sleep apnea (100). Functional Magnetic Resonance Imaging Two studies combined APOE genotyping and fMRI in per- sons at riskof AD. Bookheimer and associates (101) per- formed fMRI studies while 30 cognitively intact middle- aged and older persons (mean age, 63 years) memorized and retrieved unrelated word pairs. Statistical parametric maps of recall versus control did not differ significantly from the 14 persons without blocks for APOE-4 carriers and noncarriers. Maps were standard- ized into a common coordinate system. Both groups showed sig- APOE-4 in age, prior educational achievement, or rates of nificant MRI signal intensity increases in frontal, temporal, and AD family history. Brain activation patterns were deter- parietal regions, and the APOE-4 group had greater extent and mined during both learning and retrieval taskperiods and intensity of activation. The APOE-4 group showed additional acti- vations in the left parahippocampal region, left dorsal prefrontal were analyzed using between-group and within-subject ap- cortex, and other regions in the inferior and superior parietal proaches. Memory performance was reassessed on 12 sub- lobes, and anterior cingulate. N Engl J Med 2000;343:450–456, with significantly greater magnitude and spatial extent of MRI permission. This pattern of activation was greater in the left hemisphere, consistent with the verbal creased activation patterns could result from subclinical nature of the task, and during the retrieval rather than the neuropathology in the inferotemporal region or in the in- learning condition.

Hypochondriasis Preoccupation with bodily symptoms or functions (in the absence of somatic disease). The patient expresses thoughts of organic disease with a tendency to “somatise” the clinical presentation.
