Varicella-Zoster virus associated vasculopathy in a young male multiple sclerosis patient, treated with dimethyl fumarate.

With the increasing use of disease modifying therapies as treatment for multiple sclerosis, knowledge of the rare but possibly severe adverse events becomes increasingly important. We present a case of Varicella-Zoster virus associated vasculopathy in a young male multiple sclerosis patient, treated with dimethyl fumarate. We aim to address this rare but potentially deadly complication of varicella-Zoster virus infection and spread awareness about the increased risk in this patient population.

Blood-based Aβ42 increases in the earliest pre-pathological stage before decreasing with progressive amyloid pathology in preclinical models and human subjects: opening new avenues for prevention.

Blood-based (BB) biomarkers for Aβ and tau can indicate pathological processes in the brain, in the early pathological, even pre-symptomatic stages in Alzheimer's disease. However, the relation between BB biomarkers and AD-related processes in the brain in the earliest pre-pathology stage before amyloid pathology develops, and their relation with total brain concentrations of Aβ and tau, is poorly understood. This stage presents a critical window for the earliest prevention of AD.

Subacute combined degeneration of the cervical and dorsal spinal cord in a 40-year-old male patient: A case report.

Subacute combined degeneration of the spinal cord is a neurologic complication of vitamin B12 deficiency. It presents as a potentially reversible demyelination of the posterior and lateral columns of the cervical and dorsal spinal cord. We present the case of a 40-year-old male with progressive sensory and motor deficit from the lower extremities ascending to the mid-thoracic region.
