Objective: To investigate applicability for Boston naming test (30 items) (BNT) in Chinese elderly and identify effect for mild cognitive impairment (MCI) and Alzheimer's dementia(AD) using BNT. Methods:100 normal elderly, 38 amnesic MCI, 34 mild AD and 38 moderate AD were evaluated by neuropsychological tests (include BNT, mini mental state examination and auditory verbal memory test, etc). MMSE total score of 4 groups were 28.4?1.5, 26.1?2.6, 20.7?1.7, and 15.6?3.3, respectively. Results: Age, sex, level of education were found to be significant factors affecting overall scores of spontaneous naming in normal elderly group. Spontaneous naming score for participants of elementary, high school and college groups were 22.2?3.3, 25.5?2.5 and 26.3?1.8, respectively. Scoring of male participants higher than that of females. Spontaneous naming score of 4 groups were 24.9?3.0, 20.9?3.6, 18.7?4.0 and 15.7?4.2, respectively. As cut-off ≤22 score of spontaneous naming of BNT, the sensitivities for MCI, mild AD and moderate AD were 61%, 79% and 95% respectively; the specificities were all around 81%. Selective impairment of unfamiliar items occurred MCI and mild AD and hold of familiar item across diagnostic groups. Semantic cue naming and recognition ability by BNT showed there was progressive damage in AD patients, but less than that of spontaneous naming of BNT. Conclusion: The ability of naming is influenced by age, gender and educational level. Patients with MCI or mild AD have impairment in naming.

Objective To summarize the clinical features,neuroimaging findings and pathological characteristics of demyelinating pseudotumors(DPT)of the brain,and to differentiate it from glioma. Methods The clinical features,neuroimaging findings and pathological characteristics of 35 patients with demyelinating pseudotumors of the brain were summarized,and the diagnosis for 18 of them was confirmed by bioscopy.Results Demyelinating pseudotumors affected adults of both sexes.The onset age of patients ranged from 9 to 69 years old.There was no definite antecedent,and the clinical syndromes were atypical. Neuroimaging scans showed multiple lesions in cerebral hemisphere,while the lesion in brain stem and spinal cord was single.The symptom and neuroimaging were not parallel.While with many or large lesions, the symptoms and signs were less.The lesions were not enhanced on CT scan,but appeared round or patch enhancement on MRI scan.Nine patients with DWI all appeared high density.The myelin basic protein was useful for diagnosis.The typical pathological changes were demyelination,perivascular inflammatory infiltration and reactive gliosis.The Creutzfeuldt cells were also found in these patients.The lesions might become small or disappear after treatment,but could not serve as the criterion to exclude brain neoplasm. Conclusions DPT is a distinct demyelination disease entity,which is confusable with brain neoplasm.It is difficult to distinguish DPT from brain neoplasm with the clinical features and conventional neuroimaging scan.But DWI scan is useful.The pathological changes accord with demyelination,and Creutzfeuldt cells are also found.It is important to apply corticosteroid treatment or biopsy rather than being anxious to excise the lesions.
