Sudden changes in cognition in MS: the isolated cognitive relapse.

Of all the types of functional difficulties that a patient with multiple sclerosis (MS) can experience, cognitive change remains the area that is hardest to delineate. MS patients may experience changes in memory, attention, reasoning and executive function that can be subtle and therefore hard to detect clinically, but significant enough to compromise their daily […]

Dystonia and the inspired sensory tricks

Sensory tricks, also called geste antagoniste, is a typical feature of primary and secondary dystonias.  The sensory tricks may take many forms and if not recognized, may lead to misdiagnosis and mislabeling as “psychogenic”.  Importantly, the sensory tricks are associated with neurophysiological changes, including normalization of TMS parameters such as intracortical facilitation as well as […]

Glutamate and memory: A novel paradigm in MS

Glutamate is a major excitatory  neurotransmitter in the human brain vital for multiple functions, including memory and cognition.  Importantly, excessive glutamate activity may be harmful to the CNS, leading to neurodegeneration.  In this issue of JNNP, Muhlert and colleagues report a link between glutamate levels and memory, a unique link in MS.  Given that forgetfulness […]

Genetic mutations: Predisposing but not causative?

Hereditary IBM is an autosomal recessive myopathy characterized by distal muscle weakness, and the absence of the classical IBM phenotype.  mutations in the UDP-N-acetylglucosamine 2-epimerase/N-acetylmannosamine kinase (GNE) gene has been linked with development of this myopathy.  However, there has been a paucity of genotype-phenotype correlation studies, critical for understanding disease mechanisms.   In this issue […]

Thunderclap headache and subarachnoid haemorrhage: yes, it’s as bad as it sounds.

Aside from publishing ground-breaking insights into the mechanisms of neurological disease, JNNP also publishes many manuscripts that focus on common hard-to-manage clinical problems, things that neurologists come across on a daily basis. In this issue of JNNP, there is a very interesting paper from Bakker and colleagues http://jnnp.bmj.com/content/85/8/885.abstract that concerns one of the most feared […]

MS and Pregnancy: Control the disease before conception for good outcomes?

Pregnancy has been traditionally associated with lower frequency of relapses and more quiescent MS disease activity.  Consequently, cessation of medications is encouraged, and is necessary for some of the newer oral therapies.  In this issue of JNNP the Italisn MS group publish an important and elegant paper documenting that the control of disease post-partum is […]
