REVIEW
Patrick Roth, Dorothee Gramatzki, Michael Weller
PURPOSE OF REVIEW: Glioblastoma represents one of the major challenges in neurooncology and approximately half of the patients are 60 years or older. We summarize the particular situation of elderly glioblastoma patients with a focus on therapeutic considerations. RECENT FINDINGS: Favorable molecular markers such as mutations in the isocitrate dehydrogenase (IDH) 1 or 2 genes are virtually absent in glioblastomas in elderly patients. Treatment options are similar to the situation in young patients and comprise surgical resection, radiation therapy, and alkylating chemotherapy...

Parkinson's disease is a widely heterogeneous disorder with a broad list of motor and nonmotor manifestations. Identifying subtypes of Parkinson's disease is one of the top clinical and research priorities. This review aims to summarize the most valid conventional and recent subtyping solutions that have been introduced so far and to update our current knowledge with recent discoveries on the association between subtypes and disease progression. We also discuss the challenges of subtyping in the context of Parkinson's disease, stability of the subtypes over time, and potential clinical implications...

Huntington's disease (HD) is an autosomal dominantly inherited neurodegenerative disease characterized by progressive motor, behavioral, and cognitive decline, ending in death. Despite the discovery of the underlying genetic mutation more than 20 years ago, treatment remains focused on symptomatic management. Chorea, the most recognizable symptom, responds to medication that reduces dopaminergic neurotransmission. Psychiatric symptoms such as depression and anxiety may also respond well to symptomatic therapies...

REVIEW
Erik H Middlebrooks, Lawrence Ver Hoef, Jerzy P Szaflarski
In recent years, the field of neuroimaging has undergone dramatic development. Specifically, of importance for clinicians and researchers managing patients with epilepsies, new methods of brain imaging in search of the seizure-producing abnormalities have been implemented, and older methods have undergone additional refinement. Methodology to predict seizure freedom and cognitive outcome has also rapidly progressed. In general, the image data processing methods are very different and more complicated than even a decade ago...

Mutations in the SNCA gene, which encodes the α-synuclein protein, were the first discovered genetic causes of familial parkinsonism with Lewy pathology. To date, six different SNCA missense mutations as well as multiplications are known to cause parkinsonism. For this review, we performed a literature search to identify all published cases of SNCA-related parkinsonism to provide an updated summary of the clinical and neuropathological features of parkinsonism due to SNCA mutations. Familial parkinsonism associated with SNCA is rare, but α-synuclein aggregation is a core feature of sporadic parkinsonism, including Parkinson's disease, dementia with Lewy bodies, and multiple system atrophy...

REVIEW
Yumna Saeed, Sabra M Abbott
Alzheimer's disease (AD) is increasing in prevalence and has a significant impact on caregivers and the healthcare system. One of the many physiologic process affected by AD is the circadian system, with disruption reflected in abnormalities of the sleep-wake cycle. This interaction is bidirectional, with circadian and sleep disruption influencing disease progression. Understanding the bidirectional relationship between AD and circadian disruption may allow for earlier recognition of the potential to develop dementia as well as improved targeted approaches for therapy...

Multiple Sclerosis (MS) is a chronic, disabling neurologic disease that has its onset in young adulthood. While the knowledge about underlying pathogenesis of MS has improved significantly over the last few decades, the exact cause still eludes us. Despite the availability of several United States Food and Drug Administration-approved disease-modifying therapies (DMT) for MS in the last two decades, the disease remains disabling for many. DMT use is limited by its partial effectiveness, significant side effects in many cases, and high cost that leads people with MS (PwMS) to look for alternative management options...

Primary headache disorders, including migraine, are some of the most common neurological disorders presenting to hospital. Episodic syndromes that may be associated with migraine, including recurrent gastrointestinal disturbances such as abdominal migraine and cyclic vomiting, often pre-date or co-occur with the onset of migraine in a child who is at risk of developing the headache condition. The purpose of this review is to evaluate the two most common episodic syndromes, abdominal migraine and cyclic vomiting syndrome, including their pathophysiology, common presentations, and diagnostic criteria...

Traumatic brain injury (TBI) and traumatic spinal cord injury (SCI), collectively termed neurotrauma, are two parallel neurological conditions that can cause long-lasting neurological impairment and other comorbidities in patients, while at the same time, can create a high burden to society. To date, there are still no FDA-approved therapeutic interventions for either TBI or SCI. Recent advances in proteomic technologies, including tandem mass spectrometry, as well as imaging mass spectrometry, have enabled new approaches to study the differential proteome in TBI and SCI with the use of either animal disease models and/or biosamples from clinical observational studies...

#11
REVIEW
Katja Lohmann, Christine Klein
Mainly due to the advent of next-generation sequencing (NGS), the field of genetics of dystonia has rapidly grown in recent years, which led to the discovery of a number of novel dystonia genes and the development of a new classification and nomenclature for inherited dystonias. In addition, new findings from both in vivo and in vitro studies have been published on the role of previously known dystonia genes, extending our understanding of the pathophysiology of dystonia. We here review the current knowledge and recent findings in the known genes for isolated dystonia TOR1A, THAP1, and GNAL as well as for the combined dystonias due to mutations in GCH1, ATP1A3, and SGCE...

REVIEW
Martin Schain, William Charles Kreisl
The potential for positron emission tomography (PET) to detect neuroinflammation in vivo has sparked a remarkable interest in various disciplines of neuroscience. Early PET radioligands, such as [(11)C]PK(R)-11195 for the 18-kDa translocator protein (TSPO) and [(11)C]L-deprenyl for monoamine oxidase B, have been used in studies designed to clarify the role of neuroinflammation in a variety of psychiatric and neurological disorders. Recent years have witnessed the development of several second-generation PET radioligands for TSPO and radioligands to measure endogenous targets that are active in various stages of the inflammatory cascade, such as cyclooxygenase and arachidonic acid...

REVIEW
Melissa Rayhill, Rebecca Burch
Observational studies suggest that closure of a patent foramen ovale for other indications may reduce or even eliminate migraine attacks, particularly migraine with aura. The first randomized clinical trial of patent foramen ovale (PFO) closure for prevention of migraine, the MIST trial, showed negative results. The results of the other two completed studies in this area have recently been published in the last year. PRIMA and PREMIUM were also both negative for their primary endpoints. The PREMIUM trial did show a reduction in headache days in the migraine with aura subgroup but the final results of this subset analysis have not been published...

REVIEW
Anna Gryglas, Robert Smigiel
Migraine and stroke are common, disabling neurologic disorders, with a high socioeconomic burden. A link between them has been proposed years ago, and various theories have been proposed to explain this bidirectional relation. However, the precise causes remain unclear. We briefly summarize existing hypotheses of this correlation seeking for recommendations for stroke prevention in migraineurs, if any exist. Among the strongest suggested theories of migraine-stroke association are cortical spreading depression, endovascular dysfunction, vasoconstriction, neurogenic inflammation, hypercoagulability, increased prevalence of vascular risk factors, shared genetic defects, cervical artery dissection, and patent foramen ovale...

Huntington disease (HD) is an autosomal dominant neurodegenerative condition caused by a CAG trinucleotide expansion in the huntingtin gene. At present, the HD field is experiencing exciting times with the assessment for the first time in human subjects of interventions aimed at core disease mechanisms. Out of a portfolio of interventions that claim a potential disease-modifying effect in HD, the target huntingtin has more robust validation. In this review, we discuss the spectrum of huntingtin-lowering therapies that are currently being considered...

REVIEW
Margaret Slavin, Jessica Ailani
PURPOSE OF REVIEW: Migraine is a common disorder causing attacks of neurological dysfunction and pain. Treatment ranges from pharmacological to lifestyle changes to improve both frequency and severity of attacks. Focus on lifestyle changes, especially diet, is often discussed during clinical visits in the care of migraine patients. RECENT FINDINGS: Diet may play a role in triggering migraine, but available evidence on migraine and diet is limited. When advising patients on dietary changes to improve migraine, it is important to acknowledge the limits in evidence and the larger role that diet may play in lifestyle changes...

Degeneration of neuron and axons following injury to cells with which they synapse is termed trans-synaptic degeneration. This phenomenon may be seen in postsynaptic neurons (anterograde) or in presynaptic neurons (retrograde). Retrograde trans-synaptic degeneration (RTSD) of the retinal ganglion cells and retinal nerve fiber layer following injury to the occipital lobe has been well documented histologically in animal studies, but its occurrence in the human retina was, for many years, felt to be limited to cases of neonatal injury during a critical period of neuronal development...
