We evaluated the association of HSV-1, HHV-6, and VZV with Alzheimer's disease (AD) and Parkinson's disease (PD). Brain specimens for viral DNA polymerase chain reaction represented 34 patients with AD, 40 with PD, and 40 controls. One AD patient (2.9%) was positive for HSV-1 DNA, 88.2% for HHV-6 DNA, and 26.5% for VZV DNA; 17.5% of PD patients were HSV-1(More)
The clinical, genetic, and morphological features of a previously unknown progressive neuropsychiatric disease are presented. By genealogical investigation of the background of an uncharacteristic case of presumed organic psychosis, we traced 71 relatives from four generations. The anamnestic data showed various combinations of psychiatric symptoms(More)
We investigated histamine concentration in post-mortem brain samples of patients with Parkinson's disease (PD, n = 24), multiple system atrophy (MSA, n = 8) and age-matched controls (n = 27). Histamine concentrations were significantly increased in the putamen (to 159% of the control mean), substantia nigra pars compacta (to 201%), internal globus pallidus(More)
Brain tissue from 44 patients with Parkinson's disease (PD) and 36 age-matched controls was examined for choline acetyltransferase (ChAT) activity, and for densities of D1 and D2 dopamine receptors. Brain samples were examined for Alzheimer' disease (AD) type changes and for Lewy bodies (LBs), and for apolipoprotein E genotype. Patients were evaluated for(More)
In order to investigate the correlation between single section (SS) and disector (DS) counts for estimating the pigmented neurons in the pars compacta of the substantia nigra (SNpc), 12 patients with Parkinson's disease (PD) and seven controls were studied. The SS counts were obtained at the level of the exit of the third cranial nerve in the SNpc. The DS(More)
Estrogens may be implicated in the development of Alzheimer's disease (AD). Most of their effects are mediated via receptors whose function and expression may be modified by DNA polymorphisms. Here the estrogen receptor 1 gene (ESR1) polymorphisms XbaI and PvuII were analyzed in 214 AD patients and 290 controls. In logistic regression analysis, a(More)
The disector (DS) is a method by which it is possible to estimate the density of cells in a volume of tissue, and when associated with Cavalieri's principle, the total number of cells of a neural nucleus. Since the introduction of this method, there has been some uncertainty about the value of cell counts estimated using single section (SS). To compare(More)
The effect of 32 weeks' alcohol treatment on the number and affinity of dopamine and muscarinic receptor sites in rat striatum were measured using 3H-spiperone and 3H-quinuclidinylbenzilate (3H-QNB) as radioligands. The number of dopamine receptor sites was 38 per cent and the number of muscarinic receptor sites 36 per cent lower in the alcohol group than(More)
Quantitative estimation of neuronal numbers in the human substantia nigra (SN) can be achieved by a conventional single section (SS) count or by the more modern stereological disector (DS) count. However, counting results from SS counts are potentially biased and might not accurately reflect the total neuronal number in the SN or the changes in the total(More)
Amygdala, hippocampus and six cortical gyri were examined for the Lewy body (LB) degeneration and Alzheimer's disease (AD) type changes in 45 patients with Parkinson's disease (PD). For detection of LBs, the brain areas were stained with an antibody against alpha-synuclein. The extent of neuropathological lesions was investigated in relation to cognitive(More)
