Molecular imbalance linked to brain tumour seizures 

Researchers in France may have discovered why some patients with a type of brain tumour have epileptic seizures.

Their study, published in Science Translational Medicine, suggests that seizures in patients with glioma may be linked to an imbalance of chloride – which is involved in nerve activity – in certain brain cells.

Whether a patient has seizures is linked to how aggressive their tumour is – with less aggressive cases being more prone to epilepsy as tumour cells slowly progress and alter brain tissue.

Brain Tumour cells found circulating in blood 

German scientists have discovered rogue brain tumour cells in patient blood samples, challenging the idea that this type of cancer doesn’t generally spread beyond the brain.

Researchers from the University Medical Center Hamburg-Eppendorf, in Hamburg, found that patients with an aggressive form of brain tumour known as glioblastoma multiforme sometimes have tumour cells circulating in their blood.

In the US, Duke University investigators have recently published an esoteric molecular genetics research finding that may increase our ability to understand the biology of pediatric intrinsic brainstem gliomas.
