ABSTRACT
Background:
Movement disorders are common causes of disability, especially in older people. As the practice of neuroscience grows in Delta State, South-South Nigeria, there is need to create a data base on this neurological syndrome.
Objective: The aim of this study is to assess the types and frequency of movement disorders and to determine their age and sex prevalence.
Methodology: The records of all patients diagnosed with movement disorder who attended the Neurology Clinic of Delta State University Teaching Hospital, Oghara, from January 2011 to December 2014 were retrieved from the data base of the clinic and the Health Information Department, and analyzed.
Results: The frequency of the various movement disorders were: Parkinsonism 68 (59.6%), dystonia 21 (18.4%), tremors 15 (13.2%), myoclonus 4 (3.5%), cerebellar ataxia 2 (1.8%), freezing 1 (0.9%), restless legs syndrome 1 (0.9%), hyperekplexia 1 (0.9%) and tics 1 (0.9%). The patients were 90(78.9%) males and 24 (21.1%) females, and their mean age was 58.3 19.1years. Of all the patients diagnosed with parkinsonism, 88.2% had Parkinson's disease, and young onset (=50years) parkinsonism was found in 10.3% of them. Among the patients with dystonia, 71.4% were focal, 19% generalized and 9.52% segmental.
Conclusions: Parkinsonism, dystonia and essential tremors are the predominant movement disorders seen in the clinic. It is not clear why the frequency of dystonia is higher in this study compared to other studies in the country. A population based study is, therefore, needed to establish the true prevalence and burden of movement disorders in the region.
