Parkinson's Disease (PD) is a neurodegenerative disease that affects millions of people around the world. Diagnostics tools based on the clinical symptoms have been developed by the scientific community mostly in the last decade. This study proposes a new method of PD detection from gait signals, using artificial neural networks and a novel technique framework called Neighborhood Representation Local Binary Pattern (NR-LBP). Vertical Ground Reaction Force (VGRF) readings are preprocessed and transformed using several methods within the proposed framework. Statistical features are extracted from the transformed data, and the Student's t-test test is used to create different feature sets. A simple artificial neural network is trained over these features to detect PD, and its performance is evaluated using different metrics. Classification accuracy of 98.3% and Matthews Correlation Coefficient of 0.959 are obtained, indicating high-performance classification. Based on these performance measures, the proposed NR-LBP algorithm is compared to the regular LBP algorithm and found to be contributing positively to classification performance when various types of transformations are used in combination.

Investigating conversion from mild cognitive impairment to alzheimer's disease using latent space manipulation Ayvaz, Deniz Sezin; Baytaş, İnci M. (Orta Doğu Teknik Üniversitesi Enformatik Enstitüsü; 2022-10) Alzheimer’s disease, a progressive neurologic disorder, is the most common cause of dementia, affecting millions worldwide. Mild Cognitive Impairment (MCI) is considered an intermediate stage before Alzheimer's. Early prediction of the conversion from MCI to Alzheimer's is crucial to take necessary precautions for decelerating the disease progression and developing suitable treatments. This study proposes a deep learning framework to identify patients whose diagnoses might change from MCI to Alzheimer’s in ...
Personalized Remote Monitoring of the Atrial Fibrillation Patients with Electronic Implant Devices Laleci, Gokce; Dogac, Asuman; Yuksel, Mustafa; Kabak, Yildiray; Arbelo, Elena; Danmayr, Franz; Hinterbuchner, Lynne; Chronaki, Catherine; Eichelberg, Marco; Lüpkes, Christian (Hindawi Limited, 2011-6) Cardiovascular Implantable Electronic Devices (CIED) are gaining popularity in treating patients with heart disease. Remote monitoring through care management systems enables continuous surveillance of such patients by checking device functions and clinical events. These care management systems include decision support capabilities based on clinical guidelines. Data input to such systems are from different information sources including medical devices and Electronic Health Records (EHRs). Although evidence-...
Association of cytochrome P4502E1 and NAD(P)H:quinone oxidoreductase 1 genetic polymorphisms with susceptibility to large artery atherosclerotic ischemic stroke: a case-control study in the Turkish population Ozcelik, Aysun Turkanoglu; CAN DEMİRDÖĞEN, BİRSEN; Demirkaya, Seref; Adalı, Orhan (Springer Science and Business Media LLC, 2017-06-01) Stroke, a major cause of death and disability, is described as interruption or severe reduction of blood flow in cerebral arteries. Oxidative stress plays an important role in the pathogenesis of atherosclerosis and carotid atherosclerosis is a risk factor for stroke. Combination of multiple environmental and genetic risk factors is thought to increase stroke. Therefore, investigation of the polymorphisms of enzymes is of crucial importance to determine the molecular etiology of the disease. To test this hy...
Gene-level pathogenicity scores for alzheimer’s disease using genomic variants from rna-seq data Bozkurt, Fatma Betül; İlgün, Atılay; Uzuner, Dilara; Çakır, Tunahan (Orta Doğu Teknik Üniversitesi Enformatik Enstitüsü; 2022-10) Alzheimer’s disease (AD) is a complex neurodegenerative disorder affecting millions of people worldwide. Next-generation sequencing technologies such as whole-exome/genome sequencing have been widely used for detecting the variants in the genome to understand the disease etiology and unravel underlying molecular mechanisms. Alternatively, RNA-Seq data can also be used to detect variants. Since AD is a complex disease, several variants are involved in the disease pathogenesis. By using scoring algorithms, it...
Association between gamma aminobutyric acid (GABA) type B receptors gene polymorphisms and idiopathic generalized epilepsy Eroğlu, Ezgi; Adalı, Orhan; Demirdöğen, Birsen Can; Department of Biology (2011) Epilepsy is neurological disorder affecting 0.5 to 1% of the population all around the world. It is characterized by the seizures, which are the sudden alterations of behavior due to a temporary change in electrical functioning of the brain. Idiopathic generalized epilepsy (IGE) accounts for one-fifth of all the other epilepsy types, and several gene mutations were identified as the causes of IGE. In general, voltage-gated and ligand-gated ion channel mutations are linked with seizure formation. Gamma amino...
