Abstract

The aim of the study was to compare the measurable quantitative indicators of neurons and neuroglia in the gyrus precentralis region in relatively healthy individuals who died from nonviolent death and not as an outcome of the disease with similar indicators in those who died as a result of lifetime neurodegenerative diseases. Material and methods. 47 cases of nonviolent death were examined: 6 persons were relatively healthy individuals without a history of neurological diseases (average age – 67.0±7.7 years), in 2 persons– parkinsonism was diagnosed in vivo (G20.X, average age 77.0±7.1 years), in 23 persons – G93.4 (unspecified encephalopathy, 51.6±14.1 years), in 13 persons – G31.2 (degeneration of the nervous system caused by alcohol, 55.5±8.4 years). There were 32 men and 15 women. Sex differences were not taken into account in statistical processing. Results. in relatively healthy patients, the median number of neurons (N) is 26.0 (percentiles 10¸90 – 22,0¸29,0 ), coefficient of variation (CV) – 11.0, area of neurons, microns 2 (SN) – 265.3 (234.2¸352.5), CV = 16.6; neuroglia (NG) – 80.0 (75 ¸88), CV = 6.0; neuroglial index (NGI) – 3.1 (2.6¸3.8), CV = 3.2, neuroglial area, microns2 (SNG) – 15.3 (9.9¸25.9, KV = 38.2. In the deceased G20.X – N = 2.0 (1.0¸5.0), p = 0.0116, CV = 54.0, SN = 88.8 (53.6¸117.6), p = 0.0124, CV = 31.1; NG = 32.0 (21.0¸37.0), p = 0.4179, CV = 21.0, SNG = 12.3 (8.1¸20.0), p = 0.0006, CV = 36.1; NGI = 12.2 (6.8¸28.0), p = 0.000, CV = 57.0. In G93.4 – N = 3.0 (1.0¸4.0), p = 0.0065, CV = 35.0, SN = 177.6 (47.9¸299.6), p = 0.0007, CV = 52.4; NG = 83.0 (68.0¸94.0), p = 0.1618, CV = 10, SNG = 14.6 (9.9¸21.0), p = 0.0007, CV = 31.6; NGI = 28.7 (19.3¸83.0), p = 0.0000, CV = 56.0. In G31.2 – N = 15.0 (11.0¸20.0), p = 0.6767, CV = 21.0, SN = 59.7 (37.9¸77.8), p = 0.0000, CV = 28.1; NG = 62.0 (49.0¸77.0), p = 0.0477, CV = 16.0, SNG = 14.6 (9.2¸21.7), p = 0.0122, CV = 33.4; NGI = 3.8 (2.7¸7.0), p = 0.0003, CV = 38.2. Conclusions: 1) in parkinsonism, a significant decrease in the number and area of neurons and neuroglia was revealed; 2) in G93.4, neurons are more involved in the pathological process than glial cells; 3) in G31.2, there is an equally large decrease in the number of neurons and glial cells, but the area of neurons decreases more significantly than in glial cells.
