Diagnostically, headache is the easy part of migraine. It is the surrounds of migraine--the aura, prodrome and postdrome--that can be most challenging, and confused with other pathologies. This article examines the definition and variants of migraine; alternative diagnoses for which migraine may be mistaken (mimics); conditions that lie between migraine and other diagnoses (borderlands) and the possible presentations of migraine posing as other conditions (chameleons). ⋯ Migraine is more often a chameleon than a mimic; and it is the careful history that usually makes the distinction. Given migraine's prevalence of 10-15%, relatively uncommon features of migraine occur quite often, in comparison with frequent manifestations of less common diseases. Thus, even rare or under-recognised presentations of migraine come into the differential diagnosis of many presentations.

Traumatic brain injury (TBI) remains a major public health problem. This review aims to present the principles upon which modern TBI management should be based. The early management phase aims to achieve haemodynamic stability, limit secondary insults (eg hypotension, hypoxia), obtain accurate neurological assessment and appropriately select patients for further investigation. ⋯ TBI is associated with a number of complications, some of which require specialist referral. Patients with post-concussion syndrome can be helped by supportive management in the context of a multi-disciplinary neurotrauma clinic and by patient support groups. Specialist neurorehabilitation after TBI is important for improving outcome.

Review Case ReportsRare neurological diseases: a practical approach to management.
Although neurologists are frequently faced with the management of rare diseases, there is little generic guidance for the approach to management. There are complexities with respect to diagnosis, counselling, treatment and monitoring which are idiosyncratic to rare diseases. ⋯ We discuss current issues, guidance from regulatory bodies, and offer practical tips for diagnosis, treatment and monitoring, including the use of decision tree analysis. We offer a generic algorithm to aid neurologists when facing rare conditions.

ReviewWhen the going gets tough: how to select patients with Parkinson's disease for advanced therapies.
Levodopa-induced motor complications of Parkinson's disease, including motor fluctuations and dyskinesias, become increasingly frequent as the disease progresses, and are often disabling. Oral and transdermal therapies have limited efficacy in controlling these problems. Advanced device-aided therapies, including continuous infusion of apomorphine, deep brain stimulation and levodopa-carbidopa intestinal gel can all ameliorate these complications. This review summarises the principles of each of these therapies, their modes of action, efficacy and adverse effects, and gives advice on timely identification of suitable patients and how to decide on the most appropriate therapy for a given patient.
