Neuropathological changes in elderly residents of Oslo, Norway were characterised with respect to the cerebral substrates of dementia. Ninety-two brains were examined, representing 41% of all deaths occurring in 10 nursing homes during a 9-month period. The autopsy cohort showed a similar mean age (85 years) and sex ratio (73% female) and proportion of demented patients (75%) compared to all the patients resident in these homes who died during the same period. Clinical data was compiled retrospectively. Diagnosis was made using the CERAD protocol, and criteria for the diagnosis of Lewy body dementia. Lewy body formation was present in 20% and cerebral infarction in 21% of patients. In the demented group (69 patients) 90% fulfilled CERAD criteria for definite or probable Alzheimer's disease. Eight demented cases had absent neocortical neurofibrillary tangles and 6 other cases showed Lewy body dementia (9% of demented patients). A further 8 of these demented cases had brain stem Lewy bodies with only minimal cortical involvement. Thirteen cases (19% of the sample) had cerebral infarcts but these were considered to be clinically significant in only 4 (6%). In the non-demented patients (23) 4 patients had brain stem Lewy bodies and 6 had cerebral infarcts. Despite inclusion criteria biased towards the collection of Alzheimer's disease and normal patients, both Lewy body dementia (7%) and cerebral infarcts contributing to dementia (6%) were frequent.

Neurodegeneration in bipolar disorder (BPD) is poorly understood. Therefore, the current study was designed to assess the immunohistochemical changes in neurodegenerative markers in patients with BPD. Eleven consecutive autopsy cases diagnosed with BPD were analyzed. Sections were obtained from archival paraffin blocks of representative areas and stained using conventional methods, as well as immunostained with several antibodies to screen for neurodegenerative diseases. Age- and non-argyrophilic grains (AGs) degeneration matched controls were selected for each case. Clinical information was retrospectively collected from medical charts. All patients were men, and the average age of death was 70 years. Neuropathological diagnoses included dementia with grains (2), argyrophilic grain disease (2), corticobasal degeneration (CBD, 1), Lewy body disease (1), hypoxic encephalopathy (1) and cerebral infarction (1). All cases showed AGs to various degrees. Three patients died in their 50s; one demonstrated dementia with Lewy bodies, while the other two showed abundant AGs in the thalamus and amygdala. Of the three patients who died in their 60s, one showed AGs preferentially in the thalamus and amygdala, while the others demonstrated limbic predominance. The patients who died in/after their 70s demonstrated AGs similar to controls, except for the patient with CBD. Our data provides potentiality that neurodegenerative diseases may be an underlying pathology in certain cases of BPD.
