Electrophysiology enables the objective assessment of peripheral nerve function in vivo. Traditional nerve conduction measures such as amplitude and latency detect chronic axon loss and demyelination, respectively. Axonal excitability techniques "by threshold tracking" expand upon these measures by providing information regarding the activity of ion channels, pumps and exchangers that relate to acute function and may precede degenerative events. As such, the use of axonal excitability in animal models of neurological disorders may provide a useful in vivo measure to assess novel therapeutic interventions...

Multiple sclerosis (MS) is an inflammatory disorder targeting the central nervous system (CNS). The relapsing-remitting phase of MS is largely driven by peripheral activation of autoreactive T-helper (Th) 1 and Th17 lymphocytes. In contrast, compartmentalized inflammation within the CNS, including diffuse activation of innate myeloid cells, characterizes the progressive phase of MS, the most debilitating phase that currently lacks satisfactory treatments. Recently, bryostatin-1 (bryo-1), a naturally occurring, CNS-permeable compound with a favorable safety profile in humans, has been shown to act on antigen-presenting cells to promote differentiation of lymphocytes into Th2 cells, an action that might benefit Th1-driven inflammatory conditions such as MS...

PURPOSE OF REVIEW: Migraine is an extremely incapacitating collection of neurological symptoms that usually includes a severe, throbbing, recurring pain on one side of the head. The World Health Organization ranks migraine as the third most prevalent disease and the seventh commonest primary pain condition in the world. Trigeminovascular-mediated central sensitization has been implicated in the development of migraine symptoms including pain following light touch. This review explores the activation and sensitization of the brain systems that have emerged from recent studies and that contribute to migraine...

A 67-year-old right-handed woman presented with dysarthria, left upper extremity weakness and right-sided neglect of 3 hours duration. Imaging of the brain revealed acute right middle cerebral artery stroke; however, tissue plasminogen activator could not be administered due to severe thrombocytopenia. A peripheral smear revealed schistocytes and the patient was treated empirically for thrombotic thrombocytopenic purpura (TTP) with therapeutic plasma exchange. An extensive workup revealed no embolic source or other cause for stroke, and a diagnosis of large vessel infarct secondary to TTP was made...

BACKGROUND: Carpal tunnel syndrome is the most common peripheral entrapment neuropathy, for which conservative treatments are the first measures taken. However, these measures are not usually sufficient. Recently major attention has been drawn to platelet-rich plasma for its possible effects on axon regeneration and neurological recovery. Although few studies have evaluated the effects of this treatment in carpal tunnel syndrome, further investigation is required to reach concrete conclusion...

Sandip Ashok Sonar, Girdhari Lal
The blood-brain barrier (BBB) is an important physiologic barrier that separates CNS from soluble inflammatory mediators and effector immune cells from peripheral circulation. The optimum function of the BBB is necessary for the homeostasis, maintenance, and proper neuronal function. The clinical and experimental findings have shown that BBB dysfunction is an early hallmark of various neurologic disorders ranging from inflammatory autoimmune, neurodegenerative, and traumatic diseases to neuroinvasive infections...

Apathy is observed across several neurological and psychiatric conditions; however, its pathogenesis remains unclear. We clarified the involvement of brain-gut signaling in the disruption of goal-directed behavior. Male C57BL/6J mice were exposed to water immersion (WI) stress for 3 days. Food intake and nesting behavior were measured as indexes of motivation. Repeated WI caused decrease in food intake and nesting behavior. Plasma levels of peptide YY (PYY), IL-6, and ratio of dopamine metabolites in the striatum were significantly elevated after WI...

BACKGROUND: Higher amyloid burden predicts gait slowing in aging. Whether and which gait characteristics are associated with amyloid burden is less clear. Gait variability may be more sensitive to amyloid burden than mean gait characteristics. METHODS: In the Baltimore Longitudinal Study of Aging, 99 older participants without neurological disease had concurrent amyloid imaging and assessment of gait characteristics. β-amyloid burden was measured using 11C-Pittsburgh compound B (PiB) positron emission tomography...

Human herpes virus 7 (HHV-7) is a cause of encephalitis, meningitis and myeloradiculoneuropathy in adults who are immunocompetent or with immunosuppression. The involvement of the peripheral nervous system is always associated with myelitis. We report a case of acute polyradiculoneuropathy due to HHV-7, without involvement of central nervous system, in an immunocompetent patient. A 35-years-old man complained of lumbar pain radiating to both buttocks. On examination muscle strength and tendon reflexes were normal...

Human T-cell lymphotropic virus (HTLV)-1-associated myelopathy (HAM) is well described. Clinical features are predominantly consistent with cord pathology, though imaging and autopsy studies also demonstrate brain inflammation. In general, this is subclinical; however, six cases have previously been reported of encephalopathy in HTLV-1-infected patients, without alternative identified aetiology. We describe three further cases of encephalitis in the UK HAM cohort (n = 142), whereas the annual incidence of acute encephalitis in the general population is 0...

The nervous system may be affected in primary immune deficiency (PID) syndromes through infectious, autoimmune, neoplastic mechanisms, or as a primary feature of the syndrome. However certain neurologic problems do not conform to these etiopathogenetic groups. We retrospectively examined PID patients seen in neurology consultation between 2014 and 2017 in order to determine the spectrum of nervous system involvement. Among patients with confirmed neurologic problems (n = 35), common manifestations were encephalopathy and global developmental/cognitive delay...
