Diabetes mellitus is associated with cognitive dysfunction and abnormalities that can be seen with brain imaging. Recent studies provide important new insights into the nature and severity of these cerebral complications that help to explain why some patients with diabetes have clinically relevant neurocognitive morbidity, whereas most are apparently unaffected. ⋯ Outside of these periods cognitive decrements mainly occur in patients with notable diabetes-related comorbidities, in particular microvascular or macrovascular complications. The identification of crucial periods and conditions for the development of diabetes-related cognitive decrements helps to draw the attention of physicians to individuals at risk and can direct future studies into the mechanisms that underlie these conditions.

Amyloid-beta (Abeta) plaque formation is a hallmark of Alzheimer's disease (AD) and precedes the onset of dementia. Abeta imaging should allow earlier diagnosis, but clinical application is hindered by the short decay half-life of current Abeta-specific ligands. (18)F-BAY94-9172 is an Abeta ligand that, due to the half-life of (18)F, is suitable for clinical use. We thus studied the effectiveness of this ligand in identifying patients with AD. ⋯ (18)F-BAY94-9172 PET discriminates between AD and FTLD or healthy controls and might facilitate integration of Abeta imaging into clinical practice.

Convulsive status epilepticus (CSE) is the most common neurological emergency in childhood and is often associated with fever. In sub-Saharan Africa, the high incidence of febrile illnesses might influence the incidence and outcome of CSE. We aimed to provide data on the incidence, causes, and outcomes of childhood CSE in this region. ⋯ Prevention of infections and appropriate early management of seizures might reduce the incidence and improve the outcome of CSE in children in sub-Saharan Africa.
