Considerations in Subtyping and Monitoring of Symptom Progression in Primary Progressive Aphasia
Authors: Sapolsky Daisy , Domoto-Reilly Kimiko , Dickerson Bradford C.
Published: November 2014

A speech-language pathologist (SLP) may be one of the initial clinical providers for a patient with primary progressive aphasia (PPA), a group of neurodegenerative diseases involving the selective, progressive deterioration of speech and/or language abilities. While the three primary subtypes of PPA have distinct profiles of language preservation and impairment, the process of identifying the subtype can be challenging for many reasons, including subtle initial symptoms which can be difficult to detect on standard testing batteries. Early and accurate subtyping is important for clinical and research applications, which we will discuss here. The SLP plays a critical role in the initial subtyping process, as well as in helping to confirm that the course and presentation are consistent with a root diagnosis of PPA, as opposed to normal aging or other etiologies. The involvement of the SLP over time then focuses on monitoring symptom severity and progression, which is a particularly relevant issue for this population. The SLP can apply this information to inform treatment planning and patient/family counseling, and to assess potential benefits from interventions including conventional and novel speech therapies, and pharmaceutical treatments as they become available.
Neuroimaging in Primary Progressive Aphasia
Authors: Bonakdarpour Borna
Published: November 2014

Neuroimaging is a standard part of a primary progressive aphasia (PPA) diagnostic work-up and an important component of research investigating changes in the speech-language network in patients with PPA. In this paper, structural neuroimaging, including computed tomography (CT), magnetic resonance imaging (MRI), and diffusion tensor imaging (DTI), as well as functional neuroimaging, including single photon emission computed tomography (SPECT), positron emission tomography (PET), and functional MRI (fMRI), are discussed. Neuroimaging, in conjunction with meticulous clinical and neuropsychological evaluation, can increase diagnostic certainty for PPA subtyping and identification of underlying pathology, which is important for justification of potential pharmacological treatments, such as cholinesterase inhibitors. MRI and, more recently, DTI, have expanded our knowledge of structural brain changes in PPA, including gray matter abnormalities as well as alterations in neuronal tracts. SPECT and PET provide information regarding brain regional blood perfusion (SPECT) or metabolism (PET). Recently, thanks to PET ligands that bind to amyloid protein, it has become possible to diagnose or rule out Alzheimer pathology as a cause for PPA and tau imaging may be forthcoming. Finally, fMRI provides a unique window into brain-behavior relations for language as well as reorganization of the language network in disease. fMRI has also been used to gauge the effects of therapeutic interventions, including language treatment, and can be used for implementation of neuromodulatory mediations, such as repetitive transcranial magnetic stimulation (TMS).
Right Temporal Variant of Frontotemporal Dementia: A Clinical Introduction
Authors: Babiak Miranda C.
Published: November 2014

Frontotemporal dementia (FTD) is a progressive, neurodegenerative syndrome that results in changes in personality, behavior, and language. The right temporal variant, a relatively under-studied and perhaps under-diagnosed clinical subtype of FTD, manifests as behavioral changes, loss of person-specific knowledge, and eventual deficits in word-finding and semantic knowledge. Thorough assessment is necessary in order to distinguish right temporal variant FTD from other dementias. Speech-language pathologists (SLPs) play an essential role in accurate diagnosis, provision of appropriate resources and referrals, and administration of effective treatments.
Analysis of phase variation of CMOS digital attenuator
Authors: Sun Pinping
Published: November 2014

A comparison of phase variation and insertion loss between a conventional digital attenuator and a proposed capacitive‐phase‐compensation digital attenuator design based on an analysis of phase variation is presented. In a standard CMOS technology, the proposed attenuator is analytically demonstrated to have less phase variation than the conventional digital attenuator due to the capacitive‐phase‐compensation network. The proposed switch can maintain <1 dB insertion loss while achieving an 8–18° improvement of phase variation than the conventional designs over 10–20 GHz, which support the theoretical analysis.
Performance analysis of energy detection‐based spectrum sensing in κ–μ shadowed fading
Authors: Aloqlah M.
Published: November 2014

The performance of an energy detector operating over κ–μ shadowed fading is investigated. A novel closed‐form expression for the average detection probability using the well‐known probability density function‐based method is derived. The unified framework, in terms of Fox's H‐function, shows that the obtained results can be used for arbitrary values of fading parameters. On the basis of this derived analytical formula, the impact of key fading parameters on the performance of the energy detector is discussed. Furthermore, the accuracy of the analytical expressions is substantiated by Monte Carlo simulation results.
Formula for self‐resonant frequency of Archimedean spiral coils
Authors: Yun Him‐Chan , Lee Gunbok , Park Wee Sang
Published: November 2014

A simple empirical formula is proposed to calculate the self‐resonant frequency of Archimedean spiral coils made of circular wire. A spiral coil can be considered as a deformed straight wire with some specific structural parameters. Each structural parameter is assumed to affect the self‐resonant frequency. Two spiral coils, one that resonates near 13.56 MHz and one that resonates near 6.78 MHz, were fabricated to test the proposed formula. The average per cent error between the measured result and the calculated result was 2.66%. The proposed formula will be helpful in the design of Archimedean spiral coils for wireless power transfer.
