Diagnosing stroke is not always straightforward. Stroke mimics such as Todd's paresis or hemiplegic migraine account for between a fifth and a quarter of suspected strokes (depending on the setting in which they are assessed). Stroke chameleons can arise when the tempo of symptom onset is not apoplectic or if the loss of function is not clearly consistent with a deficit within an arterial territory. Thrombolysis and secondary prevention have much to offer patients with stroke chameleons, though those with stroke mimics may be harmed by these treatments and have more to gain from other therapies.

Over 10 million people in Africa have epilepsy of which most have no access to appropriate treatment. Epilepsy in Africa is different- the incidence is higher, and the causes and cultural attitudes towards it differ. This article examines the epidemiology, causes and treatment of epilepsy in sub-Saharan Africa and looks at the challenges to improve access to treatment and potential solutions and the implications for neurologists in more developed countries.
