Abstract

BackgroundMovement disorders are common neurological problems, but epidemiological studies are lacking in our locality. Type of movement disorder depends on the site of the lesion and the type of pathologic changes.ObjectiveTo estimate the prevalence rate of dystonia, chorea, and athetosis, in Al Quseir City (Red Sea Governorate), Egypt.MethodsThis study is a part of a door to door survey of major neurological disorders that was conducted in Al Quseir City, Red Sea Governorate, Egypt, on a sample size of 33,285 subjects. They were screened through 3 neurologists and 15 social workers. Then, each of the three staff members of neurology subjected positive cases to meticulous clinical evaluation separately.ResultsThirteen cases with dystonia, 7 cases with chorea and 5 cases with athetosis were found with prevalence rates of 39/100,000, 21/100,000, and 15/100,000 respectively.ConclusionPrevalence rates of dystonia, chorea, and athetosis in Al Quseir City are higher than those of the worldwide. This may be attributed to some specific environmental factors of this locality.

Highlights

The basal ganglia are organized to facilitate and harmonize voluntary movements and to inhibit competing movements that might interfere with the desired movement
The aim of this study is to estimate the prevalence of dystonia, chorea, and athetosis in Al Quseir City, Red Sea Governorate (Egypt) as a part of a big project studying the epidemiology of many neurological disorders through door-to-door survey
Phase I: data collection was performed by three qualified neurologists, through a standardized screening questionnaire [9] to pick up any suspected cases of dystonia, chorea, and athetosis
