OBJECTIVE

To study clinical and epidemiological characteristics of Parkinson’s disease (PD) in Baku.

MATERIAL AND METHODS

The authors retrospectively collected information on the newly diagnosed and all patients diagnosed with PD in outpatient clinics in Baku in 2010—2019. A prospective observation was carried out in the clinic of the Department of Neurology of the Azerbaijan Medical University in 2019, where 2% of patients diagnosed with PD, who were registered in the dispensary, respectively in 2010—2019 (a total of 125 patients), were hospitalized by random selection.

RESULTS

The trend in the dynamics of incidence (Y=0.4747x+7.0665; R²=0.9731) and prevalence (Y=0.9776x+100.9; R²=0.9271) is described by a linear equation with a high degree of approximation. With age, the prevalence of PD increases and its greatest value was observed at the age of 70—79 years (186.7 per 100.000 population). In all age groups, the difference in the prevalence of PD in the female and male populations is significant (p<0.01). The proportion of patients in the first, second, third, fourth and fifth stages was 18.8; 37.5; 26.6; 11.1 and 6.0%, respectively. The values of these indicators in the groups of men (18.7; 37.5; 29.6; 7.7; 6.5%) and women (28.8; 37.6; 22.3; 16.0; 5.3%) are basically similar.

CONCLUSIONS

In Baku, there is a clearly expressed trend of growth in the incidence and prevalence of PD, the levels of which for 2010—2019 years fluctuated in the interval 7.4—12.0 and 101.4—110.6 per 100.000 population, respectively. The most noticeable clinical and epidemiological characteristic of PD in Baku is the prevalence of patients in the second stage of disease (37.5%) as well as males (59.4%).
