Electrodiagnostic Features of Vasculitic Neuropathy
Electrophysiological studies of vasculitic neuropathy indicate that the best discriminators of vasculitis vs. other axonal neuropathies are the side-to-side differences between the same bilateral nerves. When the diagnosis is uncertain, nerve biopsy may be definitive.

Insulin Resistance at the Blood-Brain Barrier in Alzheimer’s Disease
Alterations in cerebrovascular insulin receptor isoform levels are associated with Alzheimer’s disease pathology and cause deficits in insulin signaling at the level of the blood-brain barrier.

Leriglitazone for the Treatment of Adrenomyeloneuropathy
A 96-week trial of leriglitazone to slow the progression of symptoms in adrenomyeloneuropathy did not meet the primary endpoint. However, post-hoc analyses revealed a beneficial effect in patients treated earlier in their disease course.

A Population-Based Study of Progressive Multifocal Leukoencephalopathy
In this population-based cohort study of 584 cases of progressive multifocal leukoencephalopathy (PML), predisposing conditions with the highest risk of PML were human immunodeficiency virus (HIV) infection, hematological malignancies, chronic inflammatory disease, solid organ transplantation, solid malignancies, and primary immune deficiency. The one-year mortality rate was 38.2% for all cases of PML. Factors independently associated with higher mortality rate were older age, male gender, and immunosuppressive diseases, such as hematological malignancies, solid neoplasms, and HIV.

Do Spinal Cord Stimulators Really Help for Chronic Pain?
The results of a comprehensive analysis of a large clinical database regarding treatment of patients with chronic low back pain did not support the benefit of spinal cord stimulators compared to conventional medical management for chronic pain.

Magnetic Brain Stimulation for Alzheimer’s Disease
Transcranial magnetic stimulation, targeted at the precuneus to help maintain a normal default mode network, shows some promise in slowing cognitive decline and maintaining normal electrophysiology in patients with mild to moderate Alzheimer’s disease.
