Predicting Future Dementia With Retinal Optical Coherence Tomography
Optical coherence tomography (OCT) is an innovative imaging device that measures thickness of retinal nerve fiber layers and ganglion cells. Thinning of these layers is associated with current and future risk of dementia.

Use of Amyloid PET Imaging for Diagnosis of Dementia
The use of amyloid positron emission tomography scanning to assist in accurate diagnosis of patients with symptoms of cognitive impairment as well as frank dementia results in a change of diagnosis in at least 25% of patients.

Viral Therapy for Glioblastoma
In a Phase I/II trial, convection-enhanced delivery of an engineered poliovirus yielded similar median overall survival compared to historical controls. However, a small subgroup of treated patients had extended survival past two years.

Are Oral Corticosteroids as Effective as Intravenous Steroids in the Treatment of Acute Optic Neuritis?
Based on outcomes measured at one and six months following optic neuritis in the context of multiple sclerosis, these investigators reported similar efficacy when comparing oral to bioequivalent doses of intravenous steroids.

Dual Antiplatelet Therapy for Minor Ischemic Stroke or TIA
These investigators undertook this study to evaluate the effect of clopidogrel plus aspirin, vs. aspirin alone, in an international population of patients who had minor ischemic stroke or TIA — Platelet-Oriented Inhibition in New TIA and Minor Ischemic Stroke (POINT).

Tenecteplase vs. Alteplase for Ischemic Stroke
In a recent trial, treatment with tenecteplase before thrombectomy was associated with a higher incidence of reperfusion and better functional outcome than alteplase if administered to patients with ischemic stroke within 4.5 hours of symptom onset.

Prodromal Symptoms Predict the Onset of α-Synucleinopathies
In this review of the common prodromal symptoms of α-synucleinopathies, such as Parkinson’s disease, dementia with Lewy bodies, and multiple system atrophy, the authors provided a potential framework for a timeline of the development of these conditions, starting with these prodromal symptoms.

Chemotherapy-induced Neuropathy in Childhood Cancer Survivors
Long-term symptoms and disability from chemotherapy-induced peripheral neuropathy occur in more than half of childhood survivors of cancer, with vinca alkaloids and platinum agents implicated most often.

Cannabidiol: Does It Help in Drug-resistant Epileptic Encephalopathies?
In this double-blind, placebo-controlled trial, the authors investigated the efficacy of adjunctive cannabidiol in a population of severe developmental epileptic encephalopathies and found some efficacy.
