Primitive reflexes (palmomental and snout reflexes) were positive. CT scan and MRI of the brain showed a generalized cerebral atrophy. EEG, cerebrospinal fluid, Doppler sonography of the cerebral arteries, and xenon SPECT for the measurement of cerebral blood flow did not show any abnormalities. The serum vitamin B₁₂ level was in the lower normal range (307 pg/ml). The red blood count was normal. The Schilling test was pathological (9% absorption of cobalamin), but normalized after substitution of intrinsic factor (18% absorption), indicating a lack of intrinsic factor. Gastroscopy revealed atrophic gastritis, which was confirmed by biopsy. Serum titers escort service Visalia of antibodies specific for parietal cells were not elevated, however.

Detailed psychological testing (complete Wechsler Adult Intelligence Scale–Revised, Benton Visual Retention Test, Trail Making Test, and Mini-Mental State Examination [MMSE]) reflected an average overall IQ (102). Concentration and the ability to solve complex cognitive tasks were reduced, however.
