No data exists on Parkinson's disease (PD) and secondary Parkinsonism in Northwestern Nigeria. This study was designed to create a database, document the clinical profile of PD in Kano, northwestern Nigerian, and compare this to prior observations within and outside Nigeria.


A database was documented on prospective patients presenting consecutively to the Neurology out-patients clinic of the two tertiary health facilities in Kano northwestern Nigeria over a period of 4 years. Demographic and clinical data at presentation were documented for all patients. Cases were classified as PD or secondary Parkinsonism. The severity at presentation and at last visit was classified using the H and Y scale.


Over a period of 4 years, out 1153 a total of 96 patients comprising 74 males and 22 females were enrolled. Eighty (83.3%) of them had clinically diagnosed PD while 16 (16.7%) had clinical features compatible with secondary Parkinsonism. The mean age at onset of symptoms in the PD patients (mean 58.2 ± 6.72 yrs ) was more than in secondary Parkinsonism (mean 51.4 ± 10.04 and P = 0.001). There was male preponderance in both idiopathic Parkinsonism (PD) (m:f = 3.2:1) and secondary Parkinsonism (m:f = 4.3:1). Out of the patients with secondary Parkinsonism, 10 (62.5%) and 5 (31.3%) had vascular Parkinsonism and drug-induced Parkinsonism, respectively. Duration of symptoms prior to presentation ranged between 3 months and 16 years. The mean (SD) time interval from the onset of motor symptoms to diagnosis of PD was 3.6 ± 3.4 yrs and time interval for men and women (male 3.8 ± 3.7; female 2.8 ± 2.1; P = 0.249).


Clinical profile of patients with PD and secondary Parkinsonism in Kano is similar to that from other populations within Nigeria and other developing countries. However, delayed presentation, less frequent family history, lower frequency of Young-onset PD as well as treatment challenges occasioned by poverty, inadequacy of expert, and lack of newer drugs and treatment options contrasts the situation in western populations.
